ED15112-12 5 Introduction

This document contains the necessary information you need to incorporate a MicroTech III Unit Controller (i.e. Applied Rooftop, Self-Contained, Maverick II™ or Rebel™) from Daikin Applied into a building automation system (BAS). It lists ® all BACnet properties, LON WORKS variables, and corresponding MicroTech III Unit Controller data points. It also contains the BACnet Protocol Implementation Conformance Statement (PICS). BACnet and LON WORKS terms are not defined. Refer to the respective specifications for definitions and details. Unit Controller Data Points The MicroTech III Unit Controller contains data points or unit variables that are accessible from three user interfaces: the unit keypad, a BACnet network (BACnet/IP or MS/TP), or a LON WORKS network. Not all points are accessible from each interface. This manual lists all important data points and the corresponding path for each applicable interface. Refer to OM 920 (available on www.DaikinApplied.com) for keypad details. This document contains the network details necessary to incorporate the MicroTech III Unit Controller into the network. Protocol Definitions The MicroTech III Unit Controller can be configured in either an interoperable BACnet or LON WORKS network. The controller must have the corresponding communication module installed for network integration (see Reference Document section for corresponding part numbers). There are three communication modules: BACnet/IP, BACnet MS/TP (Master/Slave Token Passing), and LON WORKS . There are two LON WORKS modules: one in accordance with the LonMark Space Comfort Controller (General) functional profile and one in accordance with the Discharge Air Controller functional profile. BACnet Protocol BACnet is a standard communication protocol for Building Automation and Control Networks developed by the American National Standards Institute (ANSI) and American Society of Heating, Refrigeration and Air-conditioning Engineers (ASHRAE) specified in ANSI/ASHRAE standard 135-2008. It addresses all aspects of the various systems that are applied to building control systems. BACnet provides the communication infrastructure needed to integrate products manufactured by different vendors and to integrate building services that are now independent. LON WORKS Networks A control network specification for information exchange built upon the use of LonTalk for transmitting data developed by the Echelon Corporation. LonTalk Protocol A protocol developed and owned by the Echelon Corporation. It describes how information should be transmitted between devices on a control network. LonMark Certification LonMark certification is an official acknowledgement by the LonMark Interoperability Association that a product communicates using the LonTalk protocol and transmits and receives data per a standard LonMark functional profile. The LON WORKS communication modules are LonMark 3.4 certified in accordance with the Space Comfort Controller (SCC) and Discharge Air Controller (DAC) functional profiles.

6 ED15112-12 Basic Protocol Information

Setting Unit Controller Communications Parameters There are 12 communication parameters involved in setting up the unit controller for proper communication with the four communication module options (BACnet IP, BACnet MS/TP, LON WORKS SCC or LON WORKS DAC). These parameters are set differently depending on which communication module is ordered and shipped with the unit. The table below lists the three possible sets of default parameter settings. Not all the parameters apply to all the module options. The bold parameters can be changed using the keypad display located on the unit controller.

Communication Setup Parameter Settings Parameter Name BACnet IP BACnet MS/TP LON (DAC or SCC) DHCP On N/A N/A IP Address DHCP Enabled N/A N/A IP Subnet Mask DHCP Enabled N/A N/A Given IP Address 1 127.0.0.1 N/A N/A Given IP Subnet 255.255.255.0 N/A N/A Mask 1 Given Gateway 127.0.0.1 N/A N/A Address 1 UDP Port Number 47808 N/A N/A MSTP MAC N/A 18 N/A Address 2 MSTP Baud Rate N/A 38400 N/A Device Instance variable variable N/A Number Max APDU Length 1476 480 N/A Device Object POL908_FF2BEE 3 POL904_AD45EC28 4 N/A Name Receive Heartbeat 0Sec 0Sec 0Sec Max Master N/A 127 N/A Max Info Frames N/A 1 N/A Term Resistor N/A No 5 N/A Notes: 1. These addresses are used if DHCP is set to Off. For changes to these parameters to take effect, use the keypad display and set Apply IP Chg on the IP Setup menu to Yes and cycle power. 2. The MSTP MAC Address is set via the keypad/display. You must cycle power after changing it for the changes to take effect. 3. The last 6 digits are the last 6 digits of the MAC address. The MAC address is printed a sticker affixed to the BACnet communication module. 4. The last 8 digits are computed from the production number and date code. 5. Term Resistor is only changeable via the keypad/display. This item must be set to Yes for the first and last unit on the MS/TP network. On all other units, this variable should be set to No (default).

BACnet Networks Compatibility The MicroTech III Unit Controller Unit Controller is tested according to the BACnet Testing Laboratory (BTL) Test Plan. It is designed to meet the requirements of the BACnet Standard (ANSI/ASHRAE 135-2008) as stated in the Protocol Implementation and Conformance Statement (PICS). However, it is not BTL listed. The PICS is located at the end of this manual or the separate PICS document, ED 15113 (available on www.DaikinApplied.com .)

BACnet Objects MicroTech III Unit Controllers incorporate standard BACnet object types (i.e., object types defined in the BACnet Standard) that conform to the BACnet Standard. Each object has properties that control unit variables or data points. Some object types occur more than once in the MicroTech III Unit Controller; each occurrence or instance has different properties and controls different unit variables or data points. Each instance is designated with a unique instance index. Some

ED15112-12 7 properties can be adjusted (read/write properties, e.g., setpoints) from the network and others can only be interrogated (read- only properties, e.g., status information). Each data point accessible from a BACnet network is described with a table that gives the Object Identifier, Property Identifier, Full BACnet Reference or path, and the Name enumeration of the property.

Example of BACnet Data Point

Keypad Menu Path Standard Menus\Flow Summary\Ret/Exh Fan= Object Identifier Property Object Type Type ID Instance Name ID Binary Output 4 1 Present_Value 85 Full Reference .ExhFanState.Present_Value Enumeration 0 = Off 1 = On

Object Identifier Object Identifiers are each designated with an Object type as defined in the BACnet specification. The first column of the data point definition gives the object type. This object happens to be Return/Exhaust Fan Status (See page 88.) The object identifier is a property of the object that you can read from the object. The name of the property is “Object_Identifier” and the property identifier is 75. Each object in the unit controller has a unique identifier. BACnet object identifiers are two-part numbers of BACnet Object Identifier data type. The first part identifies the object type (the first 10 bits of the 32-bit BACnet Object Identifier [See ANSI/ASHRAE 135-2008 BACnet A Data Communication Protocol for Building Automation and Control Networks]). The first column of the data point definition gives the object type. The second part identifies the instances of that particular object type (the last 22 bits of the 32-bit BACnet Object Identifier). The object identifier is shown in the data points listing as two numbers. The first number is shown in the Type ID column and designates the Object type enumeration. The second number is shown in the Instance column and designates the instance of that particular object type. The object identifier is a property of the object that you can read from the object code. The name of the property is “Object_Identifier” and the property identifier is 75. The ASHRAE BACnet specification reserves the first 128 numbers for ASHRAE defined objects. Manufacturers may define additional object types and assign a number above 127 as long as they conform to the requirements of the ASHRAE BACnet specification. Each object also has a name. Object names are character strings. The object name is a property of the object that you can read from the object. The name of the property is “Object_Name” and the property identifier is 77. Objects are sometimes referred to as an object type and instance number as they are in the BACnet specification. The example object above would be: Binary Output, Instance 1. Property Identifier Each object has a number of properties or attributes. Each property has a unique identifier of BACnet Property Identifier data type. Property identifiers are an enumerated set; a number identifies each member. The Property Identifier enumeration number is shown in the Property ID column. In the example above the property identifier is 85. Property Name Each property also has a unique name. Property names are character strings and shown in the Property Name column. In the example above the property name is Present Value. Full Reference The full reference is the path of the property within the network where the MicroTech III Unit Controller resides. It is a character string equivalent to the object identifier and the property identifier. In the example above the full reference is .ExhFanState.Present_Value. Enumerated Values Some properties are standard data types and some are enumerated sets. If the property value is an enumerated set, all enumerated values and corresponding meaning are given in the Enumeration column of the data point listing.

MicroTech III Unit Controller Device Object Each BACnet compatible device must have one and only one BACnet Device Object. Device Object Identifier The MicroTech III Unit Controller Device Object Identifier uniquely specifies the unit within the network. The device object type for all devices is fixed by ASHRAE at 8. Therefore the device object instance number must be unique. The initial Device Object identifier is set at manufacturing. The device object identifier can be read from the unit controller. The name of the property is “Object_Identifier” and the property identifier is 75. The initial device object instance number is 1579312. This number must be unique on the entire BACnet network. The object instance number can be changed via the keypad display. You must cycle power for the change to take effect.

! CAUTION

If another device in the network already has this object identifier (instance number), you must change the instance number of one device object, so that all devices in the network have a unique device identifier.

Device Object Name The Device Object Name uniquely specifies a device in the network. It must be unique in the network. The device name for the MicroTech III Unit Controller device is to be determined. The device name is the “prefix” of all object names in the MicroTech III Unit Controller. All objects include the device name and a period “.” preceding the object name. The Device Object name is also available to the network in the device. The property name is “Object_Name” and property identifier is 77. For a BACnet IP card, the default Object Name is POL908_###### where ###### is the last 6 digits of the MAC address. For a BACnet MS/TP card, the default Object Name is POL904_######## where ######## is computed from the production number and date code. Device Object Properties The device object contains many other informative properties as shown in Table 1. Table 1. MicroTech III Air Handling Unit Controller Device Object Properties

1. For BACnet IP, the last 6 digits are the last 6 digits of the MAC address. The MAC address is printed a sticker affixed to the BACnet communication module. For BACnet MS/TP, the last 8 digit are computed from the production number printed on the bar code label affixed to the side of the module. 2. While the MicroTech III Unit Controller supports the entire set of object types, not all object types are used. See the Object List for details. 3. The BACnet communication module and the MicroTech III Unit Controller both have their own time clocks. The date and time read via BACnet could differ from the date and time in the unit controller the date or time is changed via the keypad display. The two time clocks resynchronize approximately every 60-68 minutes and after every power cycle of the unit controller or BACnet communication module.

Network Considerations Access to Properties Object properties are accessible from the network by specifying the device object identifier, object identifier, and the property identifier. To access a property, you must specify the object identifier including the device object identifier or the object name including the device object name and the property identifier.

BACnet/IP Addressing The BACnet/Internet Protocol (BACnet/IP) address of the MicroTech III Unit Controller in a BACnet/IP network consists of the four-octet Internet Protocol address followed by the two-octet UDP (User Datagram Protocol) port number. The BACnet/IP address is a six-octet value analogous to a MAC address. The IP address portion of the BACnet/IP address must be unique in the BACnet/IP network segment. The default UDP port number in the MicroTech III Unit Controller is 47808 (BAC0 in hexadecimal). The device object of the MicroTech III Unit Controller contains a Given Internet Protocol Subnet Mask (Default is 255.255.255.0) and a default Given IP address of 127.0.0.1. The controller does support DHCP (Dynamic Host Configuration Protocol) IP addressing which is enabled by default. The keypad/display can be used to configure the BACnet/IP addressing. The keypad will display the current IP address only when the network is connected. The MicroTech III Unit Controller can be incorporated into a BACnet/IP network dedicated to BACnet devices only or an Ethernet network shared with BACnet devices and other devices.

Shared Ethernet Networks Integrating the MicroTech III Unit Controller into a shared Ethernet LAN requires close cooperation with the network administrator of the shared Ethernet network. First, verify whether DHCP should or should not be enabled. If not, obtain the IP Subnet Mask of the shared network from the network administrator. Then, obtain static IP Addresses for all MicroTech III Unit Controllers you are integrating into the shared network. Finally obtain the address of an IP Router to use for sending IP messages to and from the BACnet IP subnets. Once you have these, refer to Setting Unit Controller Communication Parameters in the Basic Protocol Information section found previously in this document.

10 ED15112-12 Configuring the Unit Controller The MicroTech III Unit Controller with attached BACnet communication module is ready to operate with the default values of the various parameters. Default values may be changed with the unit’s keypad or via the network. Refer to the MicroTech III Unit Controller for Commercial Rooftop, Applied Rooftop and Self-Contained Systems (OM 920) or MicroTech III Unit Controller for Rebel Commercial Rooftop Systems (OM 1141). BACnet MS/TP Network Addressing The BACnet MS/TP device address (Media Access Control [MAC] address) of the MicroTech III Air Handling Unit Controller in a BACnet Master Slave/Token Passing (MS/TP) Local Area Network (LAN) is set using the keypad/display. Navigate to the Advanced Menus\MSTP Setup menu to change this value. You must cycle power (turn the unit controller off and then on again) in order for the new address to take effect. LON WORKS Networks LON WORKS technology, developed by Echelon Corporation, is the basis for LonMark interoperable systems. This technology is independent of the communications media. The LonMark Interoperable Association has developed standards for interoperable LON WORKS technology systems. In particular they have published standards for HVAC equipment including the Discharge Air Controller functional profile and the Space Comfort Controller functional profile. These profiles specify a number of mandatory and optional standard network variables and standard configuration parameters. This manual defines these variables and parameters available in the MicroTech III Unit Controller.

Compatibility The MicroTech III Unit Controller with LON WORKS communication module operates in accordance with the Discharge Air Controller (DAC) functional profile or the Space Comfort Controller (SCC) functional profile of the LonMark Interoperability standard.

LON WORKS Variables MicroTech III Unit Controllers incorporate LON WORKS network variables to access unit data points. The unit controller uses LON WORKS Standard Network Variable Types (SNVT) from each profile. Some data points can be adjusted (input network variables, nvi) (read/write attributes, e.g., setpoints) from the network and others can only be interrogated (output network variables, nvo) (read only attributes, e.g., status information). Configuration variables (nci) are included with the read/write attributes. Each data point accessible from a LON WORKS network is described with a table that gives the LON WORKS Name, Profile, SNVT Type, and SNVT Index. If the variable is a configuration variable the table also includes the SCPT Reference and the SCPT Index.

Example of LON WORKS Data Point LonWorks LonWorks Name Profile SNVT Type SNVT Index nvoBldgStatPress DAC, SCC SNVT_press_p 113

LON WORKS Name Each network variable has a name that you use to access the data point. This is the name of the variable from the profile. In the example above the name network variable is nvoBldgStatPress. Profile The profile column designates the MicroTech III LON WORKS Communication Module that incorporates this network variable. The variable itself may not be a standard component of that particular profile, but the communications module does implement and it is available to the network.

SNVT Type This column gives the name of the standard network variable type from the master list.

SNVT Index This column gives the number of the standard network variable type from the master list.

SCPT Reference This column gives the name of the Standard Configuration Parameter Type (SCPT) from the master list.

SCPT Index This column gives the number of the Standard Configuration Parameter Type (SCPT) from the master list.

Network Considerations Network Topology Each LON WORKS Communication Module is equipped with an FTT-10A transceiver for network communications. This transceiver allows for (1) free topology network wiring schemes using twisted pair (unshielded) cable and (2) polarity insensitive connections at each node. These features greatly simplify installation and reduce network commissioning problems. Additional nodes may be added with little regard to existing cable routing. Free Topology Networks A LON WORKS “free topology network“ means that devices (nodes) can be connected to the network in a variety of geometric configurations. For example, devices can be daisy-chained from one device to the next, connected with stub cables branching off from a main cable, and connected using a tree or star topology, or any of these configurations can be mixed on the same network. Free topology segments require termination for proper transmission performance. Only one termination is required. It may be placed anywhere along the segment . Refer to Echelon LON WORKS FTT-10A Transceiver User’s Guide for further details). Free Topology Restrictions Although free topology wiring is very flexible, there are restrictions. See below for a basic summary of limitations. Refer to the Echelon FTT-10A User’s Guide for complete details. 1. The maximum number of nodes per segment is 64. 2. The maximum total bus length depends on the wire size: Wire Size Maximum Node-to-Node Length Maximum Cable Length 24 AWG 820 ft (250 m) 1476 ft (450 m) 22 AWG 1312 ft (400 m) 1640 ft (500 m) 16 AWG 1640 ft (500 m) 1640 ft (500 m)

The longest cable path between any possible pair of nodes on a segment must not exceed the maximum node-to-node distance. If two or more paths exist between a pair of nodes (e.g., a loop topology), the longest path should be considered. Note that in a bus topology, the longest node-to-node distance is equal to the total cable length. 1. The total length of all cable in a segment must not exceed the maximum total cable length. 2. One termination is required in each segment. It may be located anywhere along the segment. Doubly Terminated Networks You can extend the maximum total cable length without using a repeater by using doubly-terminated network topology. The trade-offs are (1) this network topology must be rigorously followed during the installation and subsequent retrofits and (2) two terminations must be installed at the ends of the bus for proper transmission performance. Refer to Echelon LON WORKS FTT-10A Transceiver User’s Guide. Network Cable Termination LON WORKS network segments require termination for proper data transmission performance. The type and number of terminations depend on network topology. Refer to Echelon LON WORKS FTT-10A Transceiver User’s Guide. LonWorks Network Addressing Every Neuron Chip has a unique 48-bit Neuron ID or physical address. This address is generally used only at initial installation or for diagnostic purposes. For normal network operation, a device address is used. Device addresses are defined at the time of network configuration. All device addresses have three parts. The first part is the Domain ID, designating the domain. Devices must be in the same domain in order to communicate with each other. The second part is the Subnet ID that specifies a collection of up to 127 devices that are on a single channel or a set of channels connected by repeaters. There may be up to 255 subnets in a domain. The third part is the Node ID that identifies an individual device within the subnet.

A group is a logical collection of devices within a domain. Groups are assembled with regard for their physical location in the domain. There may be up to 256 groups in domain. A group address is the address that identifies all devices of the group. There may be any number of devices in a group when unacknowledged messaging is used. Groups are limited to 64 devices if acknowledged messaging is used. A broadcast address identifies all devices within a subnet or domain.

LON WORKS network variables for both the Discharge Air Controller and the Space Comfort Controller are defined below. Variables are used in both the Space Comfort Controller and Discharge Air Controller profiles unless marked otherwise.

12 ED15112-12

Commissioning the Network Pressing the service pin, switch on the LON WORKS Communication Module, generates a service pin message, which contains the Neuron ID and the program code identification of the node. A service pin message is a network message that is generated by a node and broadcast on the network. It can be used to commission the LON WORKS network. A network configuration tool maps device Neuron IDs to the domain/subnet/node logical addressing scheme when it creates the network image, the logical network addresses and connection information for all devices (nodes) on the network. External Interface File (XIF) LonMark guidelines specify exact documentation rules so that proprietary configuration tools are not required to commission and configure LON WORKS devices. The MicroTech III LON WORKS Communication Module is self- documenting so that any network management tool can obtain all the information needed over the network to connect it into the system and to configure and manage it. An External Interface File (a specially formatted PC text file with an extension .XIF) is also available so that any network tool can design and configure it prior to installation. XIF files are available on http://www.DaikinApplied.com/ and www.lonmark.org.

Configuring the Unit Controller 1. The MicroTech III Unit Controller is designed, programmed, and configured to be a rooftop or self-contained unit controller in accordance with either the LON MARK Discharge Air Controller (DAC) or LonMark Space Comfort Controller (SCC) functional profile. The unit is ready to operate with the default values of the various parameters set at the factory. Default values may be changed with the unit’s keypad or via the network. See the MicroTech III Unit Controller Operation Manual (OM 920).

Data Integrity The integrity of some data depends on a valid network connection to maintain current values. The following data points require a valid network connection if bound. If data points listed in Table 2 do not change after a given time, the controller reverts to local control. In the case of the LonWorks module, the variables will revert to their default values.

ED15112-12 13 Typical Application: Minimum Integration

When you have integrated the unit into your network, you can monitor and control unit operation from your workstation. At a minimum, you can: • Display and monitor a minimum of important data points on your workstation display • Turn the unit on or off from your workstation • Set the schedule from your workstation and • Operate the unit safely This section gives you the basic information and outlines a procedure to set up the unit for network control.

Set up the Unit for Network Control To control the MicroTech III Unit Controller over the network, set the Control Mode function to AUTO from the unit keypad. The keypad password (2526) is required to edit this function. For a detailed description of how to use the keypad, refer to the MicroTech III Unit Controller for Commercial Rooftop, Applied Rooftop and Self-Contained Systems (OM 920) or MicroTech III Unit Controller for Rebel Commercial Rooftop Systems (OM 1141).

Display Important Data Points Typical workstation displays of MicroTech III Unit Controller attributes include the following significant data points (page number of detailed description in parenthesis). Each data point is identified with a number that also identifies it in the Comprehensive Data Point Tables. These data points are also shaded in the comprehensive tables so that you can distinguish them from the rest of the data points in the table. References in the text of this section also identify these data points with a number and shading. Table 3. Significant Data Points

No Configuration No Temperatures/Pressures No Setpoints No Clear Alarms 1 Unit State (96) 5 Discharge Air Temperature 9 Duct Static Pressure Setpoint 14 Clear Alarms (108) (45) (49) 2 Application Mode 6 Return Air Temperature 10 Unoccupied Cooling Setpoint (34) (87) (97) 3 Occupancy (75) 7 Outdoor Air Temperature 11 Occupied Cooling Setpoint (80) (78) 4 Occupancy Mode 8 Duct Static Pressure (46) 12 Occupied Heating Setpoint (76) (79) 13 Unoccupied Heating Setpoint (98)

You can display any number of additional data points based on job requirements or individual preference. See LON WORKS Variables for lists of all LON WORKS Variables available to a LON WORKS network. See BACnet Standard Objects on page 17 for a list of all Standard BACnet Objects available to a BACnet network. For a more detailed description of all available data points, see the Detailed Data Point Information section. Network Off The unit can be turned off over the network by writing to the Application Mode. Writing AUTO to Application Mode allows the unit controller to determine its mode of operation based on input conditions. Writing OFF to Application Mode shuts down the unit, etc. The Emergency Override Mode Flag can also be used to shut down the unit from the network.

Network Occupancy Scheduling Using the keypad, set the Occupancy Mode to Auto. Schedule unit operation over the network with the Occ Scheduler input. Switching from OCC, UNOCC, BYPASS (TntOvrd), or AUTO commands the unit into the mode you select.

14 ED15112-12 Alarms and Events Alarms in a MicroTech III Unit Controller are divided into three classes: Faults, Problems, and Warnings. • Fault Alarms have the highest priority. • Problem Alarms have medium priority. • Warning Alarms have the lowest priority. Notification BACnet MicroTech III Unit Controllers may have their alarms monitored by one of four methods: 1) individually by BACnet Binary Values, 2) Alarm value using one BACnet Analog Value, 3) Alarm class, or 4) Notification Classes. 1. To monitor alarms individually, read the Present_Value of the desired Binary Value object. Each alarm has its own Binary Value object. If the Present_Value is Inactive (0), the alarm is not active. If the Present_Value is Active (1), the alarm is active. 2. To monitor alarms by alarm value, read the Present_Value property of the Alarm Value Analog Value object. The Present_Value displays a value that corresponds to the highest priority alarm that is active. It is possible to have multiple active alarms, but only the highest priority is displayed. For example, if there is a simultaneous Dirty Filter Warning (value of 24) and a Freeze Fault (value of 252), then the Freeze Fault value of 252 will display in the Present_Value because it is the higher priority alarm of the two. Once the Freeze Fault condition is corrected and the fault is cleared, the next priority active alarm value (in this example, value of 24 for Dirty Filter alarm) is displayed. The values for all alarms are described in the Alarms section tables. If the Present_Value displays a zero, there are no active alarms. 3. To monitor alarms by alarm class, read the Present_Value of the appropriate Analog Value object (Warnings, Problems and Faults). The Present_Value displays a value that corresponds to the highest priority alarm that is active for that particular alarm class. It is possible to have multiple active alarms, but only the highest priority is displayed. 4. To monitor alarms using the Notification Class objects, see the Alarm Notification section.

LON WORKS MicroTech III Unit Controllers may have their alarms monitored by one of two methods: 1) by using the In_alarm attribute of nvoUnitStatus or 2) by alarm class. 1. Alarms within MicroTech III Unit Controllers can be monitored individually by using the In Alarm attribute of the Unit Status Network Variable Output (i.e. nvoUnitStatus_in_alarm). This attribute displays a value that corresponds to the highest priority alarm that is active. It is possible to have multiple active alarms, but only the highest priority is displayed in this attribute. For example, if there is a simultaneous Dirty Filter Warning (value of 24) and a Freeze Fault (value of 252), then the Freeze Fault value of 252 will display in nvoUnitStatus_in_alarm because it is the higher priority alarm of the two. Once the Freeze Fault condition is corrected and the fault is cleared, the next priority active alarm value (in this example, value of 24 for Dirty Filter alarm) is displayed. The values for all alarms are described in the Alarms section tables. If the attribute nvoUnitStatus_in_alarm displays a zero, there are no active alarms. When the nvoUnitStatus_in_alarm attribute reads a value in the range of 1 to 99, a Warning Alarm is active. When the attribute reads a value in the range of 100 to 199, a Problem Alarm is active. When the attribute reads a value in the range of 200 to 255, a Fault Alarm is active. 2. To monitor alarms by alarm class, read nvoWarnAlarm, nvoProbAlarm and nvoFaultAlarm. The value corresponds to the highest priority alarm that is active. It is possible to have multiple active alarms, but only the highest priority is displayed.

Clearing BACnet MicroTech III Unit Controllers have one Multi-State Value objects that can be used to clear alarms. All alarms of a particular class may be cleared by writing the appropriate value to the Present Value property of ClearAlarms (2=ClearAllFaults, 3=ClearAllProblems, 4=ClearAllWarnings). All alarms of all three classes can be cleared by writing a 5 (ClearAllAlarms) to Present_Value. Once the alarms are cleared, the Present_Value of this object goes back to None (1).

LON WORKS MicroTech III Unit Controllers have one variable that can be used to clear alarms; nviClearAlarms. All alarms of a particular class may be cleared by writing the appropriate value to nviClearAlarms (1=ClearAllFaults, 2=ClearAllProblems,

ED15112-12 15 3=ClearAllWarnings). All alarms of all three classes can be cleared by writing a 4 (ClearAllAlarms) to nviClearAlarms. Once the alarms are cleared, this variable goes back to None (0).

Unit Controller Sequence of Operation The sequence of operation for a MicroTech III Unit Controller depends on the control type. Refer to the MicroTech III Unit Controller for Commercial Rootop, Applied Rooftop and Self-Contained Systems (OM 920) or MicroTech III Unit Controller for Rebel Commercial Rooftop Systems (OM 1141) available on http://www.DaikinApplied.com/, for sequence of operation details, including keypad operation.

Object Request Keypad Menu Path No Keypad Equivalent This input network variable provides the mechanism to request an operation or a mode for a functional block within a device. A request consists of an object ID (the object_id field) and an object request (the object_request field). The object ID is the functional block index for a functional block on the device. The Node Object functional block is index zero. The remaining functional blocks are numbered sequentially, starting with one.

The following functions are supported: • RQ_NORMAL - If the specified functional block was in the disabled or overridden state, this request cancels that state, and returns the functional block to normal operation. If the functional block was already in the normal state, a request to enter the normal state is not an error. After device reset, the state of functional blocks on the device is application-specific. An RQ_NORMAL request that specifies the Node Object functional block index is a request for all functional blocks in the device to leave the disabled and overridden states.

ED15112-12 73 • RQ_UPDATE_STATUS - Requests the status of the specified functional block to be sent to the nvoStatus output network variable. The state of the functional block is unchanged. An RQ_ UPDATE_STATUS request that specifies the Node Object functional block is a request for the status of the device and all functional blocks on the device. The status bits of the Node Object (with the exception of invalid_request and invalid_id ) are defined to be the inclusive- OR of the status bits of all the other functional blocks in the device; with the possible addition of error conditions and other conditions attributed to the device as a whole, rather than to any individual functional block. For example, if comm_failure is supported for the Node Object, then it should be set when reporting the Node Object functional block status whenever any of the functional blocks in the device reports communications failure, as well as when there is a communications failure at the device level. • RQ_REPORT_MASK - Requests a status mask reporting the status bits that are supported by the specified functional block to be sent to the nvoStatus output network variable. A one bit in the status mask means that the device may set the corresponding bit in the object status when the condition defined for that bit occurs. A zero bit in the status mask means that the bit is never set by the device.

Object Status Keypad Menu Path No Keypad Equivalent This output network variable reports the status for any functional block on a device. It is also used to report the status of the entire device and all functional blocks on the device. A status update consists of an object ID (the object_id field) and multiple status fields. The object ID is the functional block index as described under nviRequest . If the object ID is zero, the status of the device itself and all functional blocks on the device is reported. The status fields are one-bit bitfields. The only supported status fields are the report_mask , invalid_id , and invalid_request fields; all other status fields are not supported. • invalid_request - Set to one if an unsupported request code is received on the nviRequest input network variable. • invalid_id - Set to one if a request is received for a functional block index that is not defined in the device. No further checking of the request code is required when set to one.

74 ED15112-12 • report_mask Set to one if an RQ_REPORT_MASK request is received by the nviRequest input network variable, and the nvoStatus output network variable is set to contain the status mask. The status mask is an nvoStatus value that describes the status bits that are supported beyond the three mandatory status bits. The status mask consists of all fields in the nvoStatus output network variable, with the exception of the report_mask , invalid_id , and invalid_request fields. A one bit in the mask means that the functional block may set the corresponding bit in the nvoStatus output network variable when the condition defined for that bit occurs. A zero bit means that the functional block may never set the bit.

ED15112-12 101 Alarms and Events

Two methods of obtaining alarm information are available in the MicroTech III Unit Controller: 1) by monitoring individual alarms and 2) by monitoring alarms according to alarm class. Alarms are divided into three classes: Faults, Problems, and Warnings. Fault alarms have the highest priority. Problem alarms have the next priority. Warning alarms have the lowest priority. The alarms within each class are also prioritized. Refer to the MicroTech III Unit Controller Operation Manual (OM 920) for a description of each alarm. The MicroTech III Unit Controller has various ways of managing alarms, depending on the protocol. Using one of these mechanisms, alarms can be recognized and acknowledged by alarm class or individually, and cleared from the network by alarm class. Refer to Tables 5, 6, and 7 for details.

The following tables describe the alarm messages, indication, and method of clearing Fault, Problem, and Warning alarms. Alarms are listed in order of priority.

High Discharge Superheat Unload This event is initiated when the discharge superheat is high continueously for 15 minutes, the Automatic Event Variable compressor is On and the Effective Max Variable Compressor Capacity is greater than 53.3%. Reheat Stage Limited Event This event is initiated when the unit is configured for refrigerant circuit based reheat and the Automatic reheat valve is wide open and the unit is still not meeting the reheat setpoint. When this happens a compressor, on the opposite circuit as the reheat, is staged down. Oil Boost Event This event is initiated when the low oil flag is active (digital input is open) for 10 consecutive Automatic minutes or when oil boost is manually initiated. Alarm Monitoring The MicroTech III Unit Controller provides individual alarm identification through a unique value for each alarm. The value assigned to each alarm is the same for both BACnet and LONWORKS applications.

BACnet MicroTech III Unit Controllers may have alarms monitored by one of four methods: 1) individually by BACnet Binary Value Objects, 2) alarm value using one BACnet Analog Values, 3) alarm class or 4) Notification Classes. 1. To monitor alarms individually, read the Present_Value of the desired Binary Value. Each alarm has its own Binary Value object. If the Present_Value is Inactive (0), the alarm is not active. If the Present_Value is Active (1), the alarm is active. 2. To monitor alarms by alarm value, read the Present_Value property of the Alarm Value Analog Value object. The Present_Value displays a value that corresponds to the highest priority alarm that is active. It is possible to have multiple active alarms, but only the highest priority is displayed. For example, if there is a simultaneous Dirty Filter Warning (value of 24) and a Freeze Fault (value of 252), then the Freeze Fault value of 252 will display in the Present_Value because it is the higher priority alarm of the two. Once the Freeze Fault condition is corrected and the fault is cleared, the next priority active alarm value (in this example, value of 24 for Dirty Filter alarm) is displayed. The values for all alarms are described in the Alarms section tables. If the Present_Value displays a zero, there are no active alarms. 3. To monitor alarms by alarm class, read the Present_Value of the appropriate Analog Value object (Warnings, Problems and faults). The Present_Value displays a value that corresponds to the highest priority alarm that is active. It is possible to have multiple active alarms, but only the highest priority is displayed. 4. To monitor alarms using the Notification Class objects, see the Alarm Notification section. LONWORKS MicroTech III Unit Controllers may have their alarms monitored by one of two methods: 1) using the In_alarm attribute of nvoUnitStatus, or 2) alarm class. 1. Alarms can be monitored individually by using the In Alarm attribute of the Unit Status Network Variable Output (i.e. nvoUnitStatus_in_alarm). This attribute displays a value that corresponds to the highest priority alarm that is active. It is possible to have multiple active alarms, but only the highest priority is displayed in this attribute. For example, if there is a simultaneous Dirty Filter Warning (value of 24) and a Freeze Fault (value of 252), then the Freeze Fault value

ED15112-12 105 of 252 will display in nvoUnitStatus_in_alarm because it is the higher priority alarm of the two. Once the Freeze Fault condition is corrected and the fault is cleared, the next priority active alarm value (in this example, value of 24 for Dirty Filter alarm) is displayed. The values for all alarms are described in the Alarms section tables. If the attribute nvoUnitStatus_in_alarm displays a zero, there are no active alarms. Alarms may also be monitored by alarm class if desired. When the nvoUnitStatus_in_alarm attribute reads a value in the range of 1 to 99, a Warning Alarm is active. When the attribute reads a value in the range of 100 to 199, a Problem Alarm is active. When the attribute reads a value in the range of 200 to 255, a Fault Alarm is active. 2. To monitor alarms by alarm class, read nvoWarnAlarm, nvoProbAlarm and nvoFaultAlarm. The value corresponds to the highest priority alarm that is active. It is possible to have multiple active alarms, but only the highest priority is displayed. Alarm and Event Notification The MicroTech III Unit Controller has three Notification Class objects for alarms and uses intrinsic reporting which allows the controller to generate event notifications directed to one or more recipients (maximum 20 recipients). There is one notification class object for each class of alarms (faults, problems and warnings). You must subscribe to the notification class objects in order to use them. The Recipient List property must indicate when and to which device notification should be made. This is a standard BACnet data type as defined in ANSI/ASHRAE 135-2008, BACnet A Data Communication Protocol for Building Automation and Control Networks. The Event_Enable property of each object can be used to separately enable and disable reporting of To-OffNormal, To- Fault, and To-Normal events. For example, if you do not want an event to be generated when the object returns to a normal state after being in alarm, set the To-Normal bit of the objects Event_Enable property to 0. The tables below show the objects that support intrinsic reporting grouped with the notification classes they report to:

Recipient List Property The recipient list property (Recipient_List), of the Notification Class object, is a list of standard BACnet data type BACnetDestination elements. This data type consists of the following elements: Element Standard BACnet Data Description Type Valid Days BACnetDaysOfWeek The set of days of the week that the destination may be used between the From Time and the To Time From Time, To Time Time The window of time (inclusive) when the destination is visible on the days of the week in Valid Days Recipient BACnet Recipient The destination devices to receive the notification. A maximum of 20 destination devices is supported. Process Identifier Unsigned The handle of a process within the recipient device that is to receive the event notification Issue Confirmed Boolean (TRUE) if confirmed notifications are to be sent and (FALSE) if Notification unconfirmed notifications are to be sent Transitions BACnetEventTransitionBits A set of three flags that indicate the transition (TO-OFFNORMAL, TO-FAULT, and TO-NORMAL) that the recipient is suitable.

If the BACnet workstation or BACnet device supports intrinsic alarming, but is unable to subscribe to the recipient list property of the notification class object, the workstation or device can still receive alarm notification by adding its Device Instance to the “NC Dev 1=” or “NC Dev 2=” items on the keypad/display. These items are located on the IP Setup or MSTP Setup menus. Power must by cycled for changes to these items to take effect. Once power is cycled, the unit controller sends out a “Who-Is” command directed at the device. If the device responds, the unit controller sends out Unconfirmed Notifications for all alarms that are generated in the application. If the device does not respond to the Who-Is, the unit controller will periodically send out the Who-Is until the device responds.

Alarm Clearing BACnet Alarms can be cleared via BACnet by setting the ClearAlms variable to value greater than 1. To clear alarms by alarm class, change the Present_Value property to a 2 to clear all faults, a 3 to clear all problems or a 4 to clear all warnings. Setting this variable to a 5 will clear all alarms in all three alarm classes. After the alarms are cleared, this variable will return to None (1). LONWORKS Alarms can be cleared by alarm class using nviClearAlarms. To clear alarms in a particular class, set the value of nviClearAlarms to the appropriate value (1=Clear Faults, 2=Clear Problems, 3=Clear Warnings & 4=Clear All). If the unit is still in the alarm condition, the In Alarm attribute of the Unit Status Network Variable Output (nvoUnitStatus.in_alarm) again reads the number corresponding to the highest priority active alarm that still exists.

ED15112-12 141 BACnet Device Management

The following functions are specific to the BACnet device. These functions are used for maintenance and testing. A network management tool such as VTS is typically used to issue the network commands.

DeviceCommunicationControl - Disable The purpose of this command is to reduce network traffic for diagnostic testing of the BACnet network. When the BACnet Communication module receives a network command to Disable communications it stops communicating information to the network. An optional time may be specified for how long to suspend communications. The unit continues to operate during the Disabled state.

DeviceCommunicationControl - Enable When the BACnet Communication module receives a network command to Enable communications, MicroTech III AHU communications to BACnet is restored.

ReinitializeDevice (Reset) When the BACnet Communication module is capable of receiving a network ReinitializeDevice command to reboot itself (cold start or warm start). The functionality of a cold and warm start are the same and simple reboot the BACnet Communication module. No password is required.

For those objects, the Present_Value is not commandable or writable. 2 Changes to this property do not take effect until the power is cycled on the unit controller. After changing COV_Increment, you must wait at least one minute before cycling power. Otherwise, this change will not be saved. 3 Thought this property is writable via BACnet, if the object is setup for Intrinsic Reporting, this value will revert to the controller value. This is a safety feature so the network cannot disable alarms from occurring. 4 Writeable only if Out of Service is true. Also limited to multistate or analog. 5 Priority 5 is reserved for the application for commandable objects. BACnet writes at priority 5 will fail. 6 Priority 1 is reserved for the application for commandable objects. BACnet writes at priority 1 will fail.
