My Heat Pump is not working on Stage 1. It blows room temp air for the test. Stage 2 blows hot. My understanding is Stage 1 is the Heat Pump and Stage 2 is the emergency electric heater. I can confirm the outside unit is not running on either test. Expect it to run on Stage 1. Outside temp today is 55 F.
Carrier HP - CH13NA036-C
Warren Electric Heater - WKF1002B
Carrier Fan Coil FB4CNF042
Old thermostat wiring (left) new Wyze wiring (right).
I feel like the wiring is done properly but something is obviously off. On the old thermostat the label behind the green wire is G, behind orange is W1, behind blue is C. The rest are visible.
I did confirm that when I test the Wyze under Stage 1 and I go outside, I do not hear or see the Heat Pump is on. So I waited until today and it being 55 F so I know the HP will be used (it’s been in the 20’s and 30’s) and I hooked up the old thermostat and set to to 80 F and went outside and I can see the HP is on (fan spinning) and I can hear it.
What am I missing?
FYI I did not mess with any of the Wyze controls. Since I am using the test feature those should not come into play (comfort, energy, etc.)
Any help is greatly appreciated as I’m faced with using the old thermostat or having a professional come and look at it.
Thanks in advance!
