® 3000 Communicating Zone Control System U.S. Patent No. 9,253,260 Addendum sheet for the UT3000 Zone Control Code version 1.68 - 1.73 Applies to Daikin® FIT Inverter based systems and the Daikin® One+ communicating thermostat and Ultra-Talk® UT3000 Zone Panel “Twinning” instructions

STOP & read this bulletin before you start the Inverter! EWC Controls is proud to announce that the Ultra-Zone® UT3000 Zone Control has been approved to operate with the Daikin® FIT Inverter and Daikin® ComfortNet™ HVAC systems!

The Daikin Inverter A/C or HP will provide variable BTU capacity based on a proportional demand from the Daikin One+ thermostat and the Ultra-Zone UT3000 zone controller.

If you are installing a Daikin Inverter based system and a Daikin One+ thermostat, along with the Ultra-Zone UT3000 Zone Controller, these start-up instructions on page 1 & 2, apply to you. See page 7 for final instructions.

1. Confirm your UT3000 zone control is code version 1.68 or higher. 2. EWC highly recommends installing Daikin ONE+ thermostats in all zones. 3. Navigate to the “Home WiFi” screen of each communicating thermostat and allow the Homeowner to identify their own home WiFi network and input their own WiFi password, while you look the other way. 4. Allow sufficient time (approx 15 minutes) for all thermostats to download the latest software updates. 5. Using the Zone 1 “Master” thermostat, navigate to “Dealer Edit” and then to “Installer Wizard”. 6. Access the “Equipment Setup” folder, and select “Add Equipment”...Then select “Zone Board”. 7. On the next screen, confirm “EWC Zone Board” is shown and “designate” that thermostat as “Zone 1”.

8. Using any “Slave” thermostat other than Zone 1, navigate to “Dealer Edit” and then to “Installer Wizard”. 9. Access the “Equipment Setup” folder, and select “Add Equipment”...Then select “Zone Board”. 10. On the next screen, confirm “EWC Zone Board” is shown and “designate” thermostats as “Additional Zone”.

The Daikin One+ communicating thermostat can activate a “System Test” on the Inverter system. This test is required to calibrate the Inverter system settings and parameters. Normal cooling operations are not allowed until this test is complete. NOTE: If the “System Test” has already been performed with an existing Daikin ONE+ thermostat, there is no need to perform it again via the UT3000.

The “System Test” may last 5 to 15 minutes and MUST NOT BE INTERRUPTED! The system test must be performed via the “Master” Daikin One+ thermostat connected to the zone 1 terminal block only! See Page 2.

IMPORTANT: ALL ZONE THERMOSTATS MUST BE SET TO OFF!!! Including the Daikin One+ thermostat being used to initiate the System Test. DO NOT INTERRUPT THE TEST!!!

Follow the Daikin One+ thermostat prompts to perform a “System Test” verify “Refrigerant Charge” or “Pump- Down the System”. For a detailed commissioning and installation video, including further instructions on the Daikin One+ smart thermostat, please visit the thermostat website at: https://daikinone/smart_thermostats/oneplus/pros/

1. Any of the above “Sealed System” functions can be performed via the Daikin One+ thermostat in zone 1 only! All zone thermostats must be set to “OFF” with no demands for Cool, Heat or Fan.

2. After the system test is complete and/or the refrigerant charge has been verified, you may decide to re-access the Equipment User Menus and modify other settings such as (Cool or Heat Trim Settings, Cooling Profile, Temperature Rise, Clear Diagnostic Faults, etc).

3. You may now set all zones to demand conditioned air. See page 7 for guidance on “Naming Thermostats”.

4. Contact EWC Controls Technical Support if you have questions.

Step 1: Using the Daikin One+ thermostat Step 4: Select “Heat Pump or AC” or select connected to Zone 1 only, navigate to “Dealer “Furnace or Air Handler” in order to access Edit”, insert the password and select the the menu folders for each unit. Otherwise, Installer Wizard. select “Next Step” to move to the next screen.

Step 2: Then select “Begin Full Setup” on Step 5: Select “System Test” to advance to that screen. the next screen. You can navigate back to this screen after the system test is complete, and select “Charge Mode” to confirm that the refrigerant level in your system is correct.

Step 3: Select “Equipment Setup” to access Step 6: Select the arrow and your Inverter the equipment menu folders. Heat Pump or Air Conditioner test will start. The arrow will change to a spinning wheel indicating the test is underway. The test will last approx. 5 - 15 minutes. DO NOT interrupt the test.

U.S. Patent No. 9,253,260 3000 Refer to the “Twinning” diagram on page 4

1. Twinning requires both control panels to be the same code level. Both must be code 1.68 or 1.73.

2. Mount Panel “A” and Panel “B” in close proximity to each other and the Indoor unit. See Technical Bulletin 090375A0260-L for acceptable locations.

3. Install a dedicated 24v 60va listed transformer and run 24v power to both UT3000’s. DO NOT use separate transformers! * Do not power up yet.

4. Connect the communicating HVAC system control wiring to Panel “A” communicating SYSTEM block.

5. Connect communicating 24v thermostats to Panel “A” and Panel “B”. The Panel “A” Zone 1 must be a communicating thermostat. See page 1 for Daikin One+ thermostat setup/adding a zone controller.

6. Communicating thermostats are recommended on both panels, but only Zone 1 (Panel A) can access the communicating HVAC system menus and activate maintenance functions. See page 1 for Daikin One+ thermostat setup/adding a zone controller.

7. Connect the twinning wire connections between the communicating SYSTEM output block of Panel “B” to the communicating Zone 3 T-stat input of Panel “A”...NOTE: If Zone 3 (Panel A) is already being used, you may connect to Zone 2 (Panel A) instead. DO NOT use Zone 1 (Panel A) for twinning.

8. Install one Supply Air Sensor and connect the wires to the SAS terminals of Panel “A”.

9. Do not connect an Outside Air sensor to Panel “A”. It will retrieve the outdoor temperature from the communicating outdoor unit.

10. There is no need to connect sensors of any type to Panel “B”. It will retrieve the outdoor temperature from Panel “A”.

11. Now, Power Up the communicating HVAC system and power up the UT3000’s.

12. Panel “A” becomes the Master panel and will automatically configure and talk to the communicating HVAC system.

13. Panel “A” will automatically configure and talk to Panel “B”, which will become the Slave/Sub-panel.

14. Communicating thermostats connected to Panel “A & B” will also configure automatically.

15. Be patient and allow all devices to fully setup and configure. Typically 10 - 15 minutes.

16. Use the Zone 1 thermostat on Panel “A”, to enable the Inverter’s “Equipment System Test”. See page 1. Afterwards you can enable “Charge Mode”....It is also advisable to access the equipment diagnostic folders and clear all fault codes resulting from the installation process. Start off with a clean slate!

17. Finally, set all thermostats to operational mode and operate the HVAC system in both Heating and Cooling modes, to confirm proper operation.

When the shorted wire is removed, the panel will resume normal functions. Now you must repair or replace the shorted wire. If one or more 140mA, 350mA or 500mA breakers trip, only the device(s) connected to that block will be affected. Remove each hot wire connected to that block until the voltage is restored. Find and repair the shorted wires or device before re-connecting the wires. If there is a short between the Data 1 & 2 wires or if the Data wires are shorted to 24v or earth ground, the communicating thermostat on that zone will alert you by displaying “Call for Service”. If a non- communicating thermostat is connected and a short occurs on the 24v wires, the thermostat will not power up and that zone will not function. Find and repair the short using the methods described above. TECHNICAL SUPPORT EWC Controls provides superior toll free Troubleshooting Support for the UT3000 when you are on the job site!

STOP & read this section before you leave the job site! Installing a state of the art HVAC system requires skilled personnel who take pride in their craft. HVAC installers and technicians are highly skilled in refrigeration, sheet metal fabrication, plumbing and electricity. These days however, the HVAC technician must also be skilled in information technology.

You are not finished with this installation until you have familiarized the Homeowner with their new HVAC system and in particular the thermostats. Since the thermostat is the Homeowner’s primary means of interfacing with the HVAC system, it is imperative that you guide the Homeowner through this process.

When the HVAC system is zoned, there may be two or more thermostats in the house. When those thermostats are WiFi capable, it is important to guide the Homeowner through the WiFi setup process. Software updates and thermostat (cloud) access cannot occur, until this important step is completed. Arguably, this should have been done already (see page 1) but if not, do it before you leave with the assistance of the Homeowner. DO NOT assume the Homeowner wants to (or can) do this on their own. Offer to assist the homeowner and if they decline, then at least you tried and you can document that fact on your work order.

1. Navigate to the “Home WiFi” screen of each communicating thermostat and select “Use WiFi”. 2. Allow the Homeowner to identify their own home WiFi network and input their own WiFi password, while you look the other way. This way the Homeowner’s WiFi password remains secure.

2a. Allow all thermostats sufficient time to download the latest software updates. 2b. Meanwhile, encourage the Homeowner to download the “Daikin One” phone APP and create an on-line account using their preferred email address. 2c. Navigate to the “Home WiFi” screen of each thermostat and select “Daikin One Cloud”. 2d. Assist the Homeowner in connecting each zone thermostat to the Daikin One phone APP. * Set the location(s) of each HVAC system. ie. Home, Vacation Home, Office 1, Restaurant, etc. * Add + each thermostat one at a time, and follow the prompts on the phone APP and each zone thermostat screen. ie. Select settings / configuration / account. * When prompted, enter the 6 digit number on the thermostat screen into the phone APP, in order to synchronize each thermostat to each location. 2e. Assist and advise the Homeowner on how to “name” each zone thermostat. ie. Main floor, Basement, Upstairs, for easy identification on the phone APP. 2f. When there are two or more zoned HVAC systems in a single home or multiple job sites each with a single zoned HVAC system, be very specific when naming each zone thermostat, for easier identification on the phone APP. See examples below:

! AC #1 master 1st floor, AC #1 slave 2nd floor, AC #1 slave Basement, etc. ! AC #2 master Great room, AC #2 slave Bedrooms, AC #2 slave Living room, etc. ! AC #3 master Main office, AC #3 slave Break room, AC #3 slave Waiting room, etc. ! As you finish “naming” each thermostat, it will automatically update in the Daikin One phone APP.

After these tasks have been performed, you may now set all zone thermostats to demand conditioned air. You can also leave the job site certain that you have educated the Homeowner, which should result in fewer call backs.
