I have a heat pump with electric auxillary heat backup. I don't think I wired my new Honeywell 8320 thermostat correctly. I don't think the auxillary heat is coming on because it's taking over 2 hours for the temperature to increase 6 degrees. Can someone tell me if I have it wired right?

My old Carrier non-programmable termostat configuration:
Orange - O/W2
Red - R
Yellow - Y/Y2
Green - G
Brown - C

New Honeywell 8320 cinfiguration:
Orange - AUX
Red - R
Yellow - Y
Green - G
Brown - C

Thanks for any help

Gota have an O or B for the 4-way valve to operate in heat pump mode

If you have a heat pump, I would expect to see orange to O/B and a white wire to Aux.

option 170 = 7
option 190 = 0


Post the make and model number for your outdoor unit for verification.

Thanks for the quick response. The outside unit is a Carrier Model 38YKC 10 SEER split system heat pump. I do have a black, blue and white wire that were not used with the previous thermostat.
