I have a new gas furnace heat pump combination retrofitted into my older home. I can't seem to get all of the componants running properly together. When I try the test procedures via the T-stat all seems to check out but when ran as a system the main heat(heat pump) does work but my back up(aux/em heat) will not. I'm sure that it is a wiring issue but can't seem to come up with a solution.
I have an Amana 2-stage downflow furnace M3AMS90703BXA combined with a RHF42C2C heat pump c/w outdoor sensor with 8-wire ran to both from a Honeywell TH8320U t-stat. I have tried to follow the wiring diagram but they don't seem to be the same to that of the t-stat.
Can anyone help?
