My house has two heat pump systems (Goodman PHKJ0601F), each attached to a Honeywell RTHB6300 thermostat. The wiring from the pump to the t-stat is R->R (with a jumper to the other R terminal), Y->Y, G->G, B->W. This set up works: I turn it to heat, and hot air comes out; I turn it to cool, and cold air comes out.
However, I want to change my thermostats. The current ones don't let me set the number of cooling cycles, or have a 'span' feature like a Hunter t-stat, so I find the unit turning on/off frequently. I'd prefer to be able to set it at 81, have it let the room warm to 83 or so, and then cool it down to 79, so that the machine runs longer but less often.
I recently purchased 2 Hunter 44260 t-stats. They are, according to their literature, compatible with heat pumps and have a 'span' feature that should give me the performance that I want.
When I went to install them (same wiring as above), I could not get them to blow cold air. When I turned on the heat, they blew hot air; when I turned on the cool, they either did nothing or blew hot air. (I did this about a week ago and honestly can't remember.)
Any ideas on what I need to do to install these t-stats and have them work properly? I do have the receipt, so if I need to purchase a different t-stat to have it work, I can do that, too.
Thank you in advance for any assistance you can offer.
