For battery power, insert the 2 supplied "AA" type alka-
line 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 cor-
rectly with the +/- symbols in the battery compartment.
For 24 Volt AC power, you must connect the common

sub-base. In dual transformer installations, the tranformer
