Wireless Communication Setup
Follow these steps to setup the PROsync Wireless System
1. Choose the equipment module location.
2. Remove the front cover and attach the equipment module to the wall.
3. Wire the equipment module to the air handler.
4. Snap the cover back on. The C terminal light should be illuminated
indicating the equipment module is powered.
5. Install batteries in the main thermostat and ensure it is communicating
with the equipment module. Any changes to the main thermostat
that create a call will now be displayed at the equipment module
in the LEDs associated with the terminals.
6. Choose the install location for the T755WHO. In the tech settings, check
the “Signal Strength” tech setting and ensure the value is greater than zero.
7. Remove the subbase and attach it to the wall using screws and
anchors in the box.
8. If you want to hardwire the thermostat, connect the R and C wires.
9. Snap the thermostat onto the subbase. Make sure the connection
is secure and the display is illuminated.
10. Add any additional remote sensors as desired.
Note.
Each time a message goes back and forth between the remote
thermostat and the equipment module, the light on the equipment
module will blink blue twice, and the antenna icon on the remote will
blink twice.
