Question about Honeywell Programmable Thermostat Heater

1 Answer

My new Honeywell RTH6300B has 6 terminals: G, W, Not Used, Y, R, RC. My AC/Heater has 6 wires: Green, White, Blue, Yellow, Red and Brown. I don't know if it is a heat jumper or not. The house is two years old. I guess I can leave the brown not connected but I don't know what to do with the blue wire.

I am trying to install a Honeywell RTH2300B thermostat. I can't get the wiring. I have a red, blue orange, green, yellow, brown and white wire and B, O, G, Y, W, Not Used, R, and RC terminals. Can


what type of system are you wiring it to???? for general info b and o are used if heat pump system, g =fan (blower), Y =cooling (ac), W=heat, R and rc are 24v feed to stat, do not use rc if system does not have cooling. if it does and 24v is from one source then connect fed to r and install jumper between r and rc . you list wire colors you must identify where they are connected at other end.

HONEYWELL RTH5100B , THE WIRES I HAVE ARE BLUE, GREEN , WHITE , YELLOW, BROWN, THE A/C WILL NOT COME ON SHOULD I USE THE BLUE WIRE AND IN WHAT ? RC, R, Y, W, G, THANKS


Hi , you need to make sure rc and r are jumpered together.
R=red
G=green
W=white
Y=yellow

Blue is probably the other side of the transformer (24v) and usually would go on "c" if the thermostat has that particular post. To know for sure where blue goes, trace back to the furnace. Blue will be attached to a marked terminal either on a transformer or a circuit board. Hope this helps you.

Honeywell RTH230B cooling problems...


I printed out the instructions for your thermostat. It looks like you should have the following.

There should be jumper wire between Rh & Rc

Red wire to Rh or Rc whichever is easier since there is a jumper. This is the hot wire and all the thermostat does is connect to route it to the components needed for heating or cooling.

Blue wire, tape it up and don't use it. There is no spot on this thermostat for it. It is only used on thermostats that are powered by the transformer.

White wire to W. Powers the heat relay

Yellow wire to Y. Powers the cooling contactor

Green wire to G. Powers the indoor fan relay

There is a black jumper on the back of the face plate. Look at section 2.4 Setting J2 Jumper in the installation instructions. Make sure you have it in the right position for what you have. If you don't have them just google them.

Hope this helps.

Replacing thermostat what to do with single red wirew/bridge?


yes u leave the bridge intact and just put ur red wire to r or rc and usually they say rh and rc that is for a 2 transformer system which obviously u dont have so leave the wire intact jumped and hook ur red wire up yellow is ur ac wire white is ur heat wire and green is ur fan wire and red is ur 24 volt hot wire all a tstat does is jump that red wire to white for heat green for fan or yellow for ac but make sure ur power to ur unit is off before u change wires or u risk touching wires together and burning up transformer

Installing thermostat - extra wire?


you have to go down to your furnace and follow the thermostat wire ...it connects to a terminal strip or fan centre...the color doesn;t really matter...installers mix and match all the time....look at the furnace wiring and mark it down...Red on "R"...Green on "Y" whatever it is...and connect it accordingly upstairs...if you only have 4 thermostat wires downstairs you will need a jumper wire between RH and RC...if you have 5 wires you will see 2 wires on "R" at the furnace.,...and connect either to RH and RC at the thermostat

I bought new Honeywell non programmable,letters are different.


If you have a 5 wire thermostat then you have a two transformer system a cooling transformer and a heating transformer.
The cooling transformer wires to Rc - Y - G,
and the heating transformer wires to R - W the R terminal heating would be the #4 terminal from the old stat.

I have installed a Honeywell CT8775C, when I put it on the heat the A/C goes on!! I have checked my wiring and everything looks right? what should I do to correct it.


You should have a minimum of four thermostet wires. The red wire goes on the R terminal. White wire on the W terminal. Green wire on the G terminal. Place the yellow wire on the Y terminal. In most cases NO other terminals are used...... IF YOU DO NOT HAVE A YELLOW WIRE...... place the blue wire on the Y terminal. This should hopefully fix it. IF NOT....See if the thermostat has a RH and a RC terminal. If so I'll bet that you put the red wire on RC ternimal. this is for airconditioning ONLY. The RH terminal is for heating ONLY. Put a small jumper wire that will connect RH & RC. Then this should solve your problem.
