Provide Power
• 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.
