SOURCE: honeywell RTH230B

Normally, you should have 5 color wires: W-White, Y-Yellow, G-Green, R-Red and C-Blue.

The Blue wire is a common from the transformer on older systems, which is probably hooked to RC terminal.

Try this: Remove the blue wire and jump the RC to RH with the red wire and you will be fine. Blue wire should not be needed with the new thermostat.

This should also be stated in the instruction manual.
Hope this helps.

SOURCE: Honeywell 5+2 day programmable thermostat will keep heating to 29 degrees!

Our Honeywell thermostat is model RTH6300B. Now that the weather is getting hot, we decided to put the centeral air on. Hot air keeps blowing out. I called Honeywell several times thinking that we had fixed the problem. It still is blowing out hot air. Also, my husband checked the wires. Has anyone else had this problem? Any ideas what it could be?

SOURCE: My furnace works intermittently.

You may have a dirty flame sensor. There are a number of other possible causes as well. Rheem/Ruud/Weatherking furnaces also have problems with the connection on the blower deck.
The flame sensor sometimes must be bypassed around the MOLEX CONNECTOR in the deck due to humidity.
Hope this helps.

Honeywell ct3200 thermostat won't turn on


DON'T BUY A NEW ONE JUST YET! IF THE BATTERIES DIED & THERMOSTA LOST POWER, IT MAY HAVE LOST IT'S MEMORY. IT MOST LIKELY WENT BACK TO FACTORY DEFAULT SETTINGS, & NEEDS TO BE RE-PROGRAMMED THROUGH THE INSTALLER SET-UP MENU. HOPEFULLY YOU HAVE THE PAPERWORK FOR THE THERMOSTAT STILL & CAN POSSIBLY DO THE SET-UP YOURSELF. IT SHOULD HAVE STEP BY STEP INSTRUCTIONS FOR THIS IN THE INSTALLATION GUIDE (NOT THE OWNERS MANUAL)

Removed my non programable Honeywell RT 5220D replaced it with a Honeywell RTH6350D to run my Goodman Heat Pump. First I labeled the wires then connected wires as follows: AUX, G, C, O/B (orange wire)...


Leave the factory jumper between R & RC. Connect the wires to the new stat just as you have them labeled. Use a piece of thermostat wire to make a jumper from AUX to E terminals. Your new thermostat should give you instructions on how to access the installer set up. You are going to set it up as heat pump with aux. I see this is 2 days old but if you need any help let me know.

I install new RTH7500D thermostat Honeywell, when I set for Cool it blowes heat when I set for a Heat nothing works I wire per instruction have two stage system


Hi,
It sounds like the t-stat is programmed for a heat pump or you have a heat pump and the t-stat is programmed for a regular furnace....
Check out the manuals in the tip and go into the installer setup to change the t-stat to the proper programming for your system..

Temperature fluctuates


Actually that thermostat is adjustable for only +/- 1 degree. I would make sure it is located close to a radiator/register, whichever you have, to help close that 8 degree variance. The thing about hot water heat is that even when the boiler shuts down those radiators are still putting off heat, so the temp can still shoot up a few more degrees after the stat has been satisfied. Is the boiler shutting down when the stat hits 71* ? If not then the stat may be bad. Honeywell carries a 5 year replacement warranty on that stat. I use the Honeywell Focus stats in almost all my installations. They are a very dependable thermostat. Feel free to ask anything else that will help solve your problem...Rob

I replaced a Lennox DSL-450LX heat pump thermostat with a Honeywell RTH3100C. Everything works except the gas does not ignite when set to emergency heat. The Lennox was wired as follows: W = white wire Y1...


Hi, If indeed you do have a heat pump, there wouldn't be any gas involved as a heat pump runs on freon with a reversing valve and heat strips for aux and emerg. heat. For gas electric operation thermostat terminals are rc to rh with factory jumper. Red wire to either.W to W for Heat, Y to Y for cooling G to G for Fan. If you have a blue, you wont need it unless this is a commercial stat useing a common for the Led lights on the stat. The unit will get its 24volts through R terminal in combination with y,w,and,g. Cant be a heat-pump if you have a gas furnace.Wrong t-stat. You need a gas /elect stat. And on a 24volt programmable t-stat, the batterys are used for the program only.If the batterys die, than you will loose the program on most residential stats. On commercial stats with the common in play, when batters die the stat defaults back to the factory settings.If you had a Lennox heat-pump stat on a gas/elect unit, you need to change it. Someone was using what they had on hand. Let me know if this has helped you.I will be here if you need me. Sincerely,

GE airconditioner. Temperature setting goes up to 86 degrees by itself. Nothing can change it tried evrtything


Sounds like the stat is "defaulting" to factory setting, or, what are the programmed settings at? A programmable thermostat will revert to programmed settings unless placed in "hold". If all ok, time to get a new stat.

Permanent hold message on thermostat


press run program.... from there, set the schedule for maximum efficiency. permanent hold only shows up after the hold button has been pressed 2-3 times. If this does not fix the issue, there is a master reset button on the thermostat that will set all settings back to factory default.

How do i wire a potterton programable controller


Hi,

All you need to do is look at the wiring diagram on the back of the old room stat, you will have the following:

(normally wired with these colours)

OLD COLOUR CODING

Live (sometimes called common) - Red
Neutral - Blue
Switch Live - Yellow

NEW COLOUR CODING

Live - Brown
Neutral - Grey
Switch Live - Black

All you need to do is wire up the new stat with this in mind. (please note: if the wires are not colour coded like this then do not proceed and get an electrician)

Any problems or questions let me know

I hope this helps
