Powering the Thermostat

There are two different ways to power the thermostat:

Batteries (three AAA alkaline).

24 Vac Common wire.

Wiring 24 Vac Common

Wire the common side of the transformer to the C screw of the thermostat wallplate. When installing in a single transformer system, keep jumper wire between the R and Rc screws. When installed in a two-transformer

system, use the common from the cooling transformer to connect to C screw and remove the jumper wire between the R and Rc screws.

Inserting Batteries (Optional)

If not using a 24 Vac Common to power the thermostat, install three AAA alkaline batteries (included) in the back of the thermostat. Make sure the positive and negative terminals are oriented correctly, as marked on the device. See Fig.12.
