Your answer was to check the wire connections in the thermostat. My niece's boyfriend (who is not handy) installed the thermostat.

When I checked the wires I found that he had wired the hot wire to W2 instead of to RH. I rewired it to RH as shown in your diagram and now everything works. Thank you so much.

It took me an hour to find your site but well worth it. You saved me a ton of money. I am especially happy because I am a woman an no electrician you can be sure.

starstarstarstarstar 		Electronic air cleaner installed on furnace. NEW
by: Anonymous (sue)

Had new HVAC furnace installed 6 mos. ago. My old one had an Electronic Air Cleaner installed on the side of it. They removed it, Put in a big 6" filter, or more. I have a lot of debris coming from the house vents. Not dust, but looks like stuff from the chimney .Grime and grit. ("They supposedly put a new "bladder" in the chimney). I have allergies real bad, and had no problem with the old A/C../furnace.
The A/C is older, but I could not afford to have it replaced. It was working fine, but now gives a loud "POP" when it shuts off. Tech also put in a new thermostat, but it only works on Auto. Tech owns the company, is a nice man, but I cannot get him to come back out. I told him all this right after installation. I admit I am a female, and not too smart, but something isn't right. I pd. in full that day. Appreciate any suggestions. I am a desperate widow.

by: ron

ave a thermostat that controls both the central air [whichworks fine] and the oil boiler w/ 3 zones for hot water heat. the thermostat has temp settings and switches for the fan auto or off and heat off cool settings. The a/c is controlled at one zone only for entire house. The problem: Sometimes when the a/c is on [set on cool and auto fan] the heat also goes on in that zone only. That leads me to believe that it’s a thermostat problem. The solution maybe to separate [separate thermostats one for a/c and one for heat]. What do you think????

To Tony:

This sound like a furnace problem. You set the thermostat to 70 deg and the furnace unit is not supply the correct amount of heat.

My thermostat read is off by few increment. If your current thermostat is old, why not change the thermostat and see what happen. Here is links to “how to change thermostat”

Hi there,

I'm having a problem w/ my furnace heater thermostat. I noticed that the setting does not match the room temp. For example. I set up the temp on hold for 70deg but the actual room temp will only stay to 63deg. And it will only run short not reaching the required 70deg setting.
Is this a problem with the thermostat or the furnace itself? Please help before i call the HVAC repair man.

thank you for your assistance,
Tony

what happens if you let the red wire touch any of the other wires?

Hey, Kai

It is not good ideas to have Orange and Yellow wire attach to the same terminal.

Yellow wire is for cooling mode and Orange or Blue wire is for the reverse valve for the Heat Pump. It possible you may have gotten the wrong thermostat.

On a Honeywell thermostat, at the right hand side corner. It should said something about compatible with...

If this is Honeywell thermostat, here is the number to get help: 1-800-468-1502

Hey, Angie

This is embarrassing. I don't seem to remember answering your question relate to installing a thermostat. The credit goes to whoever answer it.
