3 Month baby and need help hooking up thermostat ASAP
I have an Hunter Thermostat Model 44155C. The labels say G, Rc, Rh, Y/O, W/B, an Y1. The wires are green red yellow white black brown orange. Which goes where? Need ASAP Have 3 month baby at home and no heat.

The wire colours mean nothing. If your old one didn't have letters or you already disconnected it, you will have to go to the furnace. Under one of the panels there will be a control board to which the thermostat wires connect and this might have the letters printed on it. Trace them back and connect them appropriately.
If you have a furnace that is like mine (a single-stage natural gas one), chances are that R is +24V, C is common, W is heat call, and G is the blower. Y is generally cooling. The furnace could be turned on by connecting R, W, and G together, I suppose, if the above doesn't work... but it won't shut off automatically.

Wiring on the old one, "X", probably a brown wire will not be used on the new stat. If it's a blue wire, this may be your common. "E" and "W2" probably wired together with a white wire, this controls electric heat. "R" with a red wire, this is 24 volt power. "O" is an orange wire, this is the reversing valve. "Y" is a yellow wire, this is the contactor. "G" is a green wire, this is the blower. This pretty accurate? On the new stat, the jumper should be connecting "RH" to "RC/R", leave it in and wire the "R" from your old one to either terminal. White from the old one will go to the "E" of the new one. If your electric heat doesn't work after the install, you may need to jumper the "W1" and "W2" with the "E". "O" wires to "O". "Y" from the old one wires to the "Y1" of the new. "G" wires to "G". "C" on the new one is common. Usually a blue wire goes here. If "X" on the old one was blue, plug it into the "C". If it was brown, I'd suggest not using a common, and installing batteries. Hope this helps.
I hate to tell you this but that thermostat will not work with your system.
The system you have is a 2 stage system and the thermostat you got will only do one stage.
You will need to get a thermostat theat is compatible with stage heating and cooling.
The W1 is the first stage heating, the W2 is second heating. The same is true for Y1 and Y2 on cooling
You could double them up, but it would defeat the encomoy reasons for having a 2 stage unit.
Wish I could give you better news..
I hope that this will help you to solve your problem!
By describing the wires from your new thermostat and your old one, it sounds like your new thermostat is not compatible with your system. If you have seven wires now, then you more than likely have a heat pump system and you have to get a thermostat that is compatible with this type of system. Then you will have the connections you need.
This is the corrcet wiring:
G - G fan relay
R - RC1, RC put a jumper RH ( to supply power to the cool and heat)
L - no wire connected (malfunction indicator) tape- off that wire
E - Emergency heat relay
B - W/B ( reversing valve in your heat pump energized during heat )
W2 - Auxilliary heat
Y - Y1 ( compressor contact)
O- Y/O ( reversing valve is energized during cool)
make sure that the system selector is on heat pump position.
There is no real color code for wiring but the standard is red wire to r, yellow wire to y,white wire to w, green wire to g, blue wire to c. since there's no c on your t- stat its probably battery operated, but in your case im betting white wire to w, and blue wire to g.
Depending on where the wires were connected on the old thermostat, would be the best place to start, but if that is not an option you could try to trace the wires back to your furnace and see where they connect to. It appears you have either an oil fired furnace, or a single stage heat pump. If you need more assistance please just provide type of heat used. Hope this helps
I have a manual thermostat with the following wire connections (Y, G, R, O, C, & E) with the respective wires attached (yellow, green, red, orange, blue, white). My 44260 has available G, Rc, Rh, Y/O, W/B, Y1. Which wires should I connect to which terminals on the 44160. Thanks.
