Provide Power
24VAC Power Terminal (C)
• For 24 Volt AC power, you must connect the common side of the transformer to the C terminal on the
thermostat sub-base. In dual transformer installations, the transformer common must come from the
cooling transformer.
• For battery power, insert the 2 supplied "AA" type alkaline batteries into the battery compartment located
in the rear housing of the thermostat. Make sure to position the Positive (+) and Negative (-) sides of the
batteries correctly with the +/- symbols in the battery compartment.
• If connecting this thermostat to a Wi-Fi network, a 24 VAC common (C wire) is required for the
following system types:
- Heat Only
- Cool Only
- Single Stage Heat Pump
- Multistage Heat Pump
NOTE: If a common "C" wire is not being used, the 2 "AA" batteries must be installed.
