SOURCE: changing a room thermostat a potterton to honeywell t6360

I think I've done it - but don't take this as absolute truth.
For the Honeywell T6360B the original Potterton wiring should be rewired as follows:
Brown [Live] goes to terminal 1; Blue [neutral] goes to Terminal 2 and the yellow/green [which is not an earth but a switched live - i.e. gives live to the heating system when the thermostat clicks in] goes to terminal 3.
Obviously all done with the power isolated and when it was switched back on we had heating again :o)
It's been on over two hours now and all seems fine.

SOURCE: honeywell thermostat

I had the same problem and decided to take a chance and call honeywell customer support. I am shocked, they solved my problem! At least in my situation we found that the blue wire ran the compressor. Instead of hooking up to "blue" on the thermostat, we hooked it up to "white." It works wonderfully now.

SOURCE: RTH6400 Honeywell - where does the blue wire go.

it all depends how things are wired inside your furnace downstairs on a basic system blue is usually a common - C and yellow is for cool - Y just leave the jumper in from R & RC R is 24v power and RC is 24v power in Cool yuo will just have to squeeze the new wire in with it before you get to far i would open up the doors on you furnace and see where the connections are in there so you dont blow any fuses

The c in the furnace that is white is going to your condenser, it must stay. ADD the blue that goes to the tstat OR brown, which ever and then use that color on your new tstat and you will be fine. Always turn power off when changing stat

Installed a Honeywell RTH6350D...no heat. I think it has to do with the wiring. Old round unit has red, white, and blue wires. Hooked up red and white but am not sure what to do with blue. Help!


normally there are 4 wires.. should be red to red which is 24 volt
green to g which is fan
white to w which is heat
and the blue could be used on y terminal for cooling
see try that and see if it helps....

I currently have a Honeywell T874C1000 and want to replace it with a programmable thermostat. It controls a cooling only air handling unit with an outdoor condensing unit. No heat.


All you have to do is note which wires are hooked to which terminals and exchange them i.e.-R(Red) to R terminal, Y(Yellow) to Y terminal, etc. The only wires you should need are the Red, Yellow, Green, and sometimes Blue if the thermostat is powered by the unit and not batteries. Here are the most common wiring procedures:

Red(R)=Power
White(W)=Heat
Green(G)=Fan
Yellow(Y)=Cooling
Blue(B/C)=Common/Ground

Hope this helps!

Not working


"G" terminal is for the fan, typically using a green wire. "C" terminal is the common, basically a ground, typically using a blue wire. Also, leave in the jumper between "RH" and "RC".

I am trying to install a RTH2310 but I do not know where the wires go. Brother in law took old Thermostat off and did not write down where they go. I have a white wire, a red wire and a green wire. Back at...


In most cases, the wires are used as this: Red=Power, White=Heat, Green=Fan/Blower Motor, Yellow=A/C. The other wires, like the one hooked to the yellow will be the condenser wires going outside. The thing I'm not sure on, is that Honeywell Thermostats usually have the terminals marked with R,W,B,G,etc. If it does, then the wires will be as color coded and just hook them back up that way. You can also test to see if those wires are what they are supposed to be by jumping the wires. You can start with red since that is supposed to be your 24v power. Jumper red and green, you should get the blower motor on, jumper the red and white, you should get the heat to come on. Same goes for a/c as explained above. Any other questions, I will be glad to help.

the normal wiring for stats is white=w=heat,red=r=24volts,green=g=fan,blue=c=common,yellow=y=cooling.
see what ties into your furnace board and match the terminals.
