Question about Honeywell Programmable Thermostat Heater

1 Answer

Thermostat displays 79 deg but really 68 in room

For some reason the room tempature shows 79 deg but the room is 68... Therefore, when I have my settings at 72 it won't turn on since it thinks the room is 79.

What does 54NC mean when displayed on my Honeywell room thermostat?


I'm guessing, I don't have your thermostat, but "NC" sounds like, "Not Connected". Check wiring at back of thermostat and at furnace.

I had my 3 year old mid-efficient furnace serviced a few months ago. I have a 4 room small bungalow. The Honeywell thermostat is set to say 72 and it says it reached 72. However, an independant...


Sounds like the switch that controls the blower is faulty. It should heat up then come on at preset temp. As for the stat where is it located. It should be located 60" off the ground not in any direct sunlight and make sure it is insulated behind the stat. You could have more heat loss in those rooms too. IE poorly insulated windows air penetrating through outlets do those walls face the wind? Is the stat located next to a heat supply?

Indoor temp is 5 degrees colder than display reads on digital thermostat


Where are you measuring the indoor temperature?
To compare it to the thermostat temperature you have to measure both temperatures at thermostat.
The thermostat will only control the temperature at the thermostat, not any where else in the room.
The room temperature depending on insulation in walls and ceiling and distance from outside wall and outside temperature, can be as high as 10° difference from outside wall to inside wall of house.
The lower the outside temperature, the greater the room difference in heating. The higher the outside temperature the greater the room difference in cooling.

I set my program for 72 degrees, but as the room heats up, it stays at 68 degrees with out getting any warmer. Though the radiator is on, it does not get any warmer, help???


Hi, The problem would not be with the thermostat, it would be with the unit itself. It may be under sized for the space you are trying to heat, I don't no how large the space is and what btu rating is of the heater. It would also depend on the insulation value and windows in your home. Does the heater run all the time and not shut off trying to keep up? Please get back to me on this so we can come up with a solution.

Thermostat does not stop heat pump unit


Most of these problems are the program settings on these way overcomplicated thermostats. You will need to re-read the instructions on setting the programs. Or bite the bullet and buy a cheaper and simpler one. If you installed it yourself, make sure the settings on the inside are correct, like gas/electric heat, and 24 volts, stuff like that.
