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.

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”

Thermostat problem
by: Anonymous

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

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
