Question about Heating & Cooling
I have either a P/n P474-0100 or P474-0220 Totaline thermostat installed in 2002. A few weeks ago we had a scheduled power outage in our area that lasted about 6-8 hours after the power was restored my thermostat never came back on. It was working fine until the outage happened. Tried the breakers but still nothing. I can't believe it is time for a new one. Any suggestions?
The power outage probably caused the thermostat to go back to factory default settings. You need to go through the advanced setup procedures in the owners manual on page 6. This will allow you to turn the heat pump back on.

Check to see if you have power at the circuit board in the furnace, as this is where the stat is powered. You may have blown the control fuse on the board. If you have power, check to see if you have 24vac on the r terminal at the board and at the stat. If you do, probably time to go shopping for a stat.
