Question about Heating & Cooling

Hunter 44100A programmable thermostat

I have 6 wires going to my old thermostat. Orange(o), green(g), yellow(y), red(r), blue(x), and white(w2). Do I just tape off the orange and blue in order to install the new thermostat? The old thermostat is a Honeywell heat pump thermostat if that matters.

    Knowing that I need the (o) wire is helpful, but where do I hook it? This thermostat only has terminals for y, w, g, rh, and rc.

    Had a feeling that would be the case. I just happened to have this thermostat sitting in a box from a previous residence and was hoping I could get some use out of it. Thanks.

After you install honeywell you have to set it; by holding down one of the bottom below the display and the right top button. This take you to the setting menu. The representative-1-800-468-1502 feed me the numbers I need to set the program and now it's working great.Thank God for representative that do their jobs well.

Yes you will need the orange (o) wire for the reversing valve in your heat pump. T-stat color code is red (r) for 24v power from transformer. Blue (x or c) is the common or the other 24v power from transformer and this will power your programmable t-stat. Orange is for the reversing valve that will switch your heat pump from cooling and heating. Green (g) controls your inside blower. Yellow (y) brings on your outside unit. White is your backup heat.

I am replacing a White-Rodgers thermostat with a Hunter 44155C and dont know where to connect the wires. I have white, red, green, blue, and yellow wires and none are labeled as to what they are.


The Yellow wire is for cooling, the white is for heating, the red is for power, the green is for blower fan, the blue is your common wire, all you should have to do is color code the wires to the thermostat. The thermostat should have the colors labeled R,W1,G,Y,B or C for common if it's wired correctly at the Air Handler or evaporator. The blue wire should go to B, or C.

Is this a heat pump? Look in the thermostat. You should have something like the following.
Red wire to R terminal
Green wire to G terminal
Yellow wire to Y terminal
White wire to W or W1
Blue or Orange wire to the O or B terminal
Brown wire to C terminal.

Let me know what you have in the thermostat. The wire colors are not always the same.

The Honeywell LR69071 (old) has 7 wires connected labeled (X W2 R O Y G E) The Hunter 44860 (new) has wire connections for ( Y1 Y2 W2 G RH RC/R B W1 E O C L) What connects with what? There is also a jumper...


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.

Need wiring diagram for Honeywell RCT8100


The old thermostat has a second stage heat which is W2. The new one doesn't have second stage heat.
The wiring your describing on the old thermostat is telling me you have a heat pump with second stage heat and the new thermostat is for air conditioning only. You will need to get a thermostat for a heat pump.

Switching old thermostat to Hunter thermostat model 44155c


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.

Need help with wiring on Hunter 44110


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.
