WIRING DIAGRAMS
CAUTION
1. Be sure to disconnect the power to the control
transformer before removing or installing thermostat.
2. Do not short compressor relay, reversing relay, aux heat
relay, fan relay or fault relay... even momentarily. This
will blow a non-replaceable fuse.
3. Do not attempt to hook up to live circuits. An accidental
connection to a component on the thermostat circuit
board could cause damage to the thermostat.
