Lennox xp15 heat pump, power outage blip
Thank you oberkc. The HP was running at full strength at the time of the 15 second power outage. I didn't think to check the thermostat right after the power blip, until about 30 minutes later, when I realized I wasn't feeling any warmer and checked the register. I assume the quick power outage caused the HP to suddenly shut off and turn back on again, which can't be any good for it. The HP and thermostat correctly did the safety delay, when I reset the breakers though, but the heat still did not come out of the register, even though the air was blowing out vigorously, like the HP was on.
I don't believe it was my back up propane furnace, because then I would have felt warm air coming out of the register, and I actually have that setting turned off in my thermostat programming.
The air coming out the register now is actually much warmer than my last edit post, so it seems to be working fine now, so that power blip while the HP was on must have been bad for it. Heavy winds are forecast in about 2 hours here in the Seattle area, so I'm getting my house up to 73 degrees temperature with a fireplace insert and HP combined right now, so that the HP could shut off before another outage hits. Of course that means my fireplace fan will shut off too, but then I'll have to get the generator out....I live in the country.
