my questions is what wires go where. i just bought a Hunter thermostat model # 44155c. on my old thermostat the wires are as followes:W2-jumps to quot;F(Yellow Wire)F-Yellow WireO/B-Light Green WireR-Red WireG-Dark GreenC-Red Wire Y-Yellow WireMy new thermostat has these options:RH, RC, G, Y/O, W/B, Y1can anyone tell me what wires go where?thank you
you were suppost to mark the wires by which they were screw to by color code; w rd blk etc.and then wire to new unit with same color code, some terminals need a small branch wire to bypass, lets say an ac with a heat pump.Ok now this is what an ac man will do, he will go to the compressor and write where the wires there are wired and then he would look up the color code and put the wires where they go. Also i relie heavily on the 800 help line number.Some ac men will put different colors on the wrong terminals, put a sticker on the unit and when there is trouble, they will call him,if all the wires were black and he knowes where they go, you see. A trusted ac man would be a great help,and remember, you're checking at the wall, not at the unit where the signals are not being recieved correctly, the thermostat is the brain, and one more thing, you are on the right track, because a progamable thermostat can save you a lot of money especiall if you're gone a lot.
Well, unfortunately, this particular Hunter model isn't well-designed for operating heat pumps, which is what I'm assuming you've got, since you've got a W2 (aux heat) wire and and O/B (compressor reversal) wire. Still, you can sorta get it to work, but it might take some trial and error, when it comes to the O/B wire, as I'll explain in a minute. Here's the connections you should make: RH - 24VAC hot - connect to R wire RC - 24VAC cool - Jumper this to the RH connector G - Fan - connect to G wire Y - Compressor - connect to Y1 The O/B wire should connect to EITHER the Y/O or W/B, depending on your heat pump. If the reversing valve of the pump is supposed to operate when it heating mode, then you connect to the W/B terminal. If the reversing valve operates in cooling mode, you connect to the Y/O terminal. The other wires should be taped off with electrical tape and left disconnected. These wires are: W2 - auxiliary heat control - leave disconnected (your thermostat can't activate auxiliary heat) F - not sure what this is, to be honest; it might be for controlling a thermostat system check LED C - 24VAC common. Your thermostat doesn't need it.
