VTech Controller Wire Harness| GE Zoneline Wire Harness
---|---
Red (24VAC)| Red–R–24VAC
Black (Common)| Black–C–Common
Purple (Fan Low)| Tan–GL–Fan Low
Green (Fan High)| Green–GH–Fan High
White (Aux Heat)| White–W–Aux Heat
Orange (4-Way/Rev)| Blue–B–Reverse Valve
Yellow (Compressor)| Yellow–Y–Compressor
Brown (Occ Out)| N/A - Once the wiring harnesses are connected, plug the Zoneline harness connector into the connector socket on the Zoneline unit. This socket is located just to the right of the red Aux Set button.
- Plug the VTech Wiring Harness into the Controller module and press the connector firmly to ensure it snaps into place. Restore power to the PTAC/PTHP.
PTAC Configuration Settings
- Press the red Aux Set button on the PTAC.
- Using the face controls, press the Mode button until the first digit in the display shows MODE 6 (Remote Thermostat).
- Using the face controls, press the Up arrow to turn this option ON, then press again to select 6A (Auto changeover thermostat).
- Press the red Aux Set button again to save the setting and exit the configuration mode.
Provisioning the W960 Thermostat
- Install 4 AAA batteries into the thermostat.
- In the display, tap the Power/Menu key to select System Configuration.
- Tap Power/Menu again to select Std. Config via TSTAT.
- Use the Up/Down arrows to select the type of PTAC you will be controlling (Conventional System or Heat Pump System), then tap the Power/Menu key to select.
- If you have a conventional system, continue to step 3. For Heat Pump systems, please move to step 5.
- For Conventional System, select the on-board profile for a Conventional single stage heat and single stage cool system with 2 fan speeds. If your conventional PTAC is not a 1 stage heat and 1 stage cool system, you will need to utilize the EC Tool app to create a custom profile, then select Adv. Config via App in the TSTAT menu for the configuration.
- Select Start Configuration to install the default settings profile.
- Once setup complete is displayed, continue to step 8 to set up Occupancy and the System Clock.
