Power Supply
While the CT102 Thermostat can run without batteries on C-wire
power, you should install batteries as well to provide power to the
unit during outages.
1. Install four (4) AA alkaline batteries following the marked polarity
in the battery compartments. Insert the battery negative end first
against the spring, then push the positive end in.
2. With all the wires connected and the unit attached to the wall, it
is time to turn the AC power back on. Reconnect the power at the
breaker you used to switch it off. The CT102 will power-up in the
OFF mode.
3. Trip the RESET button to implement the HVAC switch selections.
4. Your CT102 is not yet configured to operate your HVAC system.
You must now configure your thermostat
