44860 thermostat won't activate in heat mode

I replaced a Honeywell CT3611 on a heat pump system. The AC works fine but the heat does not activate. The system setting is on heat pump. The controll wiring is a 6 wire system.

I had the same set and problem. I had a RC wire which is the power to the AC. But didn't have an RH wire which is the power for the heat. To fix this just use the jumper wire and insert it in with the RC wire and hook it up to the RH. Fixed my problem.

Replaced an Inter therm Thermostat Model # 65a-473-765b, with a Hunter Model 44860. The Fan works on everything but the heater. Heater comes on and runs for about 2 minutes but no fan, I manually turn on fan. I have tried to put it on auto and the Fan clicks off. Everything else works fine. Hooked up Red (with jumper RH/RC) ,White,Yellow and Green wires. I have 4 more wires that were not attached to old thermostat, Blue Orange Brown and Black. What do you suggest for my next move on getting heater to come on? Thanks Mike

We had the same problem with a Rheem and a Honeywell thermostat and changed to the Hunter 44860. X is C and had to use the little jumper as in a single stage to get it to work. Made sure our span degree is 2, no less and fan set to auto.

Now here is the kicker...our white loops and goes to the emergency heat terminal as in the old thermostat. Is this coming on too?

Our heat bill jumped, but I am not sure if it had to do with the thermostat or whether is was because we had some unusually cold weather here in the south.

Currently, all is working as far as we can tell...on/off when supposed to. If we get another high bill, I will call the HVAC guy to review our wiring....never can tell if the old thermostat was right to begin with!

    Well, the saga continues. Noticed a burning smell about a day after our unit iced over. Turned air on to melt problem. 24 hrs later a burning smell..metallic/electrical, then it went away. Came back less smelly that afternoon. Call techn., fuses had some burnt spots, replaced, added freon. That nite, little smell, this morning, iced over. Is my thermostat wired correctly? They wouldn't touch it under my home warranty contract but looked at the diagram and listened to how we hooked it up.

    Got a call in today to them. If they fix it, I will post.

Honeywell Thermostat

Make sure G from indoor unit goes to G on thermostat for fan continous fan, if that doesn't work and you have 24 volts to R and C then the t'stat is bad.
For 2nd stage heat or aux.heat, on the indoor unit you need to make sure the wire W2 from the indoor unit goes to W2 on t'stat.
You don't need any wires from W1on the indoor unit to W1 at the t'stat because with a York heat pump Y1 is the contactor which turns the compressor on and you will get 1st stage heat, and for cooling the t'stat will also bring on O which is the (reversing valve) or cooling changeover relay for the cooling mode.
C = common usually black wire
R = hot usually red wire
Y or Y1 = contactor
W1 = 1st stage heat not needed for heat pump
W2 = Aux. heat indoor heat
G = fan
O = Cooling changeover relay
B = Heating changeover relay
L = System monitor
E = Emergency heat relay
