The thermostat must provide a “G” sig-
nal when there is a call for “W1.”The
unit control board will energize the
indoor blower when the compressors
are energized; however, if the thermo-
stat calls for “W2” during the anti-short-
cycle delay, the electric heat (when
installed) will be energized immediately
upon the call for “W2.”
