Thermostat temperature never changes?

I have a honeywell setback thermostat, and the temperature on the thermostat never changes below the temp. i have set on it, but it still turns on the furnace. Is it supposed to do this, or is there something wrong?

Those thermostats maintain the temperature within 1/2 of one degree. Therefore, you may not notice the temperature changing and the unit turns on more often for shorter cycles.

this is normal during the winter months. the thermostat kicks the heat on when it gets down, and kicks it off when the temp has been reached...it might be in a fraction of a degree and this would be hard to tell.
Could be you are in setup mode. Have you already programmed the stat? If yes, do you have a resume button or one that takes you back out of the set up mode? The others are correct in that your temperature should only fluctuate a degree plus or minus, depending on the temperature differential you programmed. In other words, if you set the temp in heating for 70, when the temp drops to 69, your furnace will come on. When the air temperature reaches 71, your furnace will shut off. If you set the differential to 1, that is 1/2 degree under and 1/2 degree over 70. That is a very tight range, but if you want it to be a constant 70, that is where you need it set. You can change the differential to 2, which would give you a 1 degree +/-.
