I have a Carrier Series 50QT Electric heat pump that still uses the original non programmable thermostat. I am trying to replace it with Honeywell TH6000 series programmable thermostat.

The wiring on the existing Thermostat as follows:

O - White, I am thinking this is the Reversing Valve?
Y - Blue, Cooling stage 1?
R- Red, Power
E - Jumpered to W2 Emergency Heat relay?
G- Fan
C - 24 Vac Common?

What is the proper mapping of the connections to the new thermostat? And also what are the right programming options for it?

:confused:


Thanks!

First of all you did not supply the complete model number. There is a letter after the 6000 part.

Here is a wiring diagram that will cover them all.
Just follow the directions

If you cannot follow the directions then you will probably have to call for a pro to do the install. Way to many variables to and to many chances of damaging the unit.

NOTE Honeywell has a toll free number to call if you need them.

I used that guide, namely the wiring schema for 2H/1C Heat Pump System, the problem is that it's calling for 7 wires, one for L, but my existing Thermostat only has 6. Also when I did wire it, once my heat turns on, it immediately turned on the Emergency Heat, but the air coming out of the registers was still cold.

I have they same problem with the emergency hgeat turning on immediately. What was your resolution?

Thanks
