This Summer I purchased a new HAI Omnistat2 (RC1000 WH) thermostat and honestly once the AC worked, I never tested the heat. Well the first day the heat turned on last week (Florida) I noticed it got much hotter than I wanted the heat set point, in fact it got as hot as my cool set point. Upon some investigation I discovered that although my Heat Pump turns off, the blower and heat strip (I assume this based on the temp of the heat coming from the vent) continue to run until the house reaches my cool point when the thermostat turns on the AC.
I verified this by putting the Hold to On, and switching the mode from Auto to Heat and then turning the heat point one degree warmer than the current temperature. At that point the heat turns on, and I go outside to verify the heat pump is on. Then I switch the mode to off, at which point the heat pump turns off, but the blower continues to blow. So I wait 10 minutes and it never turns off. Now I switch the mode to Cool and turn the cool point to a degree cooler than the current temperature and the Heat Pump turns on and cold air starts blowing from the vent. Now I switch the mode to off and the entire system turns off.
I checked all the wiring and everything seems in order. The only thing interesting is that the white wire connected to #6 B runs to the air handler where it is wired to both the Heat Pump and the Heat Strip. But this all worked fine with my old Omnistat1, so I'm thinking either the thermostat is messed up or my Heater, not sure how to tell which.
Here are my components.
Goodman CPLJ48-1B (condenser/heat pump)
Goodman arpt049-00c-1a (air handler)
Goodman HKR-10A (Elec Heat)
Thanks
