TEC2245-4 LONWORKS® Network Thermostat Controller with Single Proportional 1 Output and One-Speed Fan Control Installation Instructions To install the thermostat controller: 4. Pull approximately 6 in. (152 mm) of wire from the wall and insert the wire through the hole in the 1. Use a Phillips-head screwdriver to remove the thermostat controller mounting base. security screw on the bottom of the thermostat controller cover. 5. Align the thermostat controller mounting base on the wall and use the base as a template to mark Note: Normally, the security screw is packaged the two mounting hole locations. separately in a plastic bag with the thermostat controller. Skip this step if the screw is not installed 6. Position the thermostat controller mounting base on the bottom of the cover. so that the arrow on the base points upward to indicate the top of the thermostat controller. 2. Pull the bottom edge of the thermostat controller cover and open the thermostat controller as Note: If you need to install the thermostat on an illustrated in Figure 1. electrical junction box, use 2-1/2 x 4 in. (63 x 101 mm) square boxes with mud ring covers, and avoid smaller 1-1/2 x 4 in. (38 x 101 mm) or 3 x 2 in. (76 x 51 mm) square boxes. This procedure ensures that you have enough space for cabling and end-of-line devices, if needed. Note: For surface-mount applications, use durable mounting hardware such as Molly bolt anchors that cannot be easily pulled out of the mounting surface. 7. Secure the base to the wall surface using two mounting screws as illustrated in Figure 3. Note: Be careful not to overtighten the mounting screws. FIG:cvr_rmvl

Table 4: Installer Configuration Menu (Part 1 of 5) Parameter Description and Default Selection Options Appearing on Display Pswrd Sets the protective access Range: 0 to 1,000 password to prevent unauthorized access to the Installer Configuration Menu. Default: 0 Note: The default setting does not lock out access to the Installer Configuration Menu. BI1 Configuration of Binary Input 1. (None): No function is associated with an input. Default: None (Rem NSB): Remote Night Setback (NSB) via a time clock input, an occupancy sensor, or from a voltage-free contact. Contact open = Occupied; contact closed = Unoccupied. (MotionNO*): Temporary occupancy request via a motion detector input. Contact open = Unoccupied. When the contact closes, the thermostat controller goes into the occupied mode for a specified TOccTime. Once the TOccTime begins, the thermostat controller remains in the occupied mode if the contact is open, until the TOccTime expires. (MotionNC*): Temporary occupancy request via a motion detector input. Contact closed = Unoccupied. When the contact opens, the thermostat controller enters occupied mode for a specified TOccTime. Once the TOccTime begins, the thermostat controller remains in the occupied mode if the contact is closed, until the TOccTime expires. (Window**): Cancels the thermostat controller heating or cooling action when a window is open. A Window alarm is displayed indicating that the window needs to be closed to resume heating or cooling. * These settings disable any local override function. **When this setting is selected, the heating and/or cooling outputs are enabled only when the contact is closed. If the fan is set to Auto, it is enabled only when the contact is closed. If the fan is set to On, it is not affected by this setting. BI2 Configuration of Binary Input 2. (None): No function is associated with an input. Default: None (Door Dry): Door contact only has an effect if BI1 is set to MotionNO or MotionNC. (See the BI1 parameter listed previously in this table.) The occupancy is now dictated via BI1 and BI2. Any motion detected sets the zone to Occupied status. The zone remains permanently in occupied mode until the door contact switch opens momentarily. The thermostat then enters stand-by mode. If more movements are detected, the occupied mode resumes. While the door is opened, any movements detected by the remote PIR sensor or the PIR accessory cover are ignored. Use a Normally Closed contact switching device. Contact opened = Door opened, Contact closed = Door closed. (RemOVR): Temporary occupancy request via a remote input. This override function is controlled by a manual remote occupancy override. When enabled, this condition disables the override capability of the thermostat controller. (Filter): A Filter alarm is displayed. This alarm can be connected to a differential pressure switch that monitors a filter. (Service): A Service alarm is displayed on the thermostat controller when the input is energized. This input can be tied into the air conditioning unit control card, which provides an alarm should there be a malfunction.

(None): No function is associated with an input. Default: None (COC/NH): Change Over Contact/Normally Heat: A dry contact input is used to signal seasonal hot/cold water changeover. The contact closes when cold water is present. Valid for two-pipe systems only. (COC/NC): Change Over Contact/Normally Cool: A dry contact input is used to signal seasonal hot/cold water changeover. The contact closes when hot water is present. Valid for two-pipe systems only. (COS): Change Over analog Sensor: Used for hot/cold water changeover switching. Valid for two-pipe systems only. Note: Select (0): Cooling Only for SeqOpera parameter. This allows changeover to occur between Cooling only and Heating only.
