New Rheem Heat Pump install in basement with Emerson Thermostat. Turned heat on for first time in Georgia since its down to 37 degrees outside. New to heat pumps but I think I have a problem.
Thermostat is set to AUTO/Heat. Target temperature is 68 degrees and that is what T-stat reads. However, blower is blowing 52 degree air into the room. Drops room temperature to 66 degrees according to my own thermometer - Temp on T-stat doesn't budge off of 68 as my temp reading is going down. Once room hits 66 degrees, AUX kicks in on T-stat (even though T-stat still hasn't budged from 68 reading). Aux air blows 85 degrees warm until my thermometer and room heat back up. Aux kicks off, blower continues blowing but now blowing the 52 degree air again. Repeat, Repeat, Repeat every 20 minutes. Clearly T-stat knows it is getting colder, cuz it kicks Aux in at the same true temp every time.
Have original tech coming back out for 3rd time tomorrow.
I know Heat Pumps are different than furnaces, and 37 degrees outside make Heat Pumps perform less efficiently, but what the heck ....
Why does blower blow when T-stat says target temp reached and not calling for heat? My furnace shuts off and stops blowing when target temp reached.
If blowing, why blowing 52 degree air?
Why T-stat not changing temp reading but Aux kicking on and off as temp indeed goes down?
Logical answer would be defective T-stat, but this was 2nd brand we tried.
Any help would be greatly appreciated.
