TYPICAL WIRING DIAGRAMS
CAUTION
1. Be sure to disconnect the power to the control
transformer before removing or installing thermostat.
2. Do not short cooling or heating relays, or fan 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.
