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.
