3. Turn thermostat blower switch to auto position.
Indoor blower should stop.
4. Set system switch to heat or cool. Adjust thermostat
to call for heat or cool. The indoor blower,
compressor, and outdoor fan should start.
NOTE: If there was no power to 24 volt transformer,
the compressor and outdoor fan motor will not
start for 5 minutes. This is because of the
compressor short cycle protection.
