Hello i have a vision pro 8000 seriees thermostat from a previous apt, we just moved into a house and i'm pretty sure that we have a 1heat/1cool unit but i'm not 100 percent. The furnace is a carrier model # fy4anf036.
The previous thermostat was a carrier TSTATCCBHP01-B that had 6 terminals W, O, G, R, C, Y and all were wired.
i hooked up the honeywell thermostat model# th8110u1003 with
Rc & R jumped
R to R on the honewell
O to the O/B on the honeywell
Y to the Y on the honeywell
G to the G on the honeywell
C to the C on the honeywell
and i was left with an extra wire that previously plugged into the W terminal
The thermostat had power, the fan worked, but when i turned the a/c on hot air came out and when i turned the heat on nothing happend so i imagine i need to do somthing with the wire that plugs into the W.
if anyone has wiring suggestions i would appreciate it.
I contacted honeywell and they were no help, i'm hoping that i just had it wired wrong but if i need to buy a different thermostat that would be fine also. Thank you for any help and if you need more information please let me know.
Nick

You have a multistage heat pump.
The Visionpro TH8110 will not support your multistage heatpump.
The TH8320 and the TH8321 will.
W = Aux & E (use jumper)
O = O/B
G = G
R = Rc & R (use provided jumper)
C = C
Y = Y
Color codes vary, (especially C and E)
Set option 170 to 7 (2Heat/1Cool heat pump with aux. heat)
option 190 = 0 (O/B terminal is O)
"Tip of the Day" Remember to remove power first.
