during winter the heating co that does maintenance on the rented furnace came and changed the thermostat I had (Sensi) as it was no longer operating properly. They installed a Honeywell Pro Series and informed it would not work with my heat pump. I then purchased a Nest 4th gen and it was working fine until I need the cool air.
I can't say about the wiring with Sensi but on the Honeywell I had:
Y - Orange wire
G - Green
C - Black
W - White
R - Red
As per instructions I now have :
Y1 - Orange
G- Green
Rc - Red ( I did switched them at some point)
W1 - White
C - Black
Systems runs, heats well but impossible to have cool air.
My home system is central furnace gas with Amana heat pump ANZ13.
I tried to move W1 to W2 as on very first thermostat I had (Sensi) it was set on AUX but Nest rejects the attempt.
Suggestions would be much appreciated.
