SOURCE: display is blank and furnace fan stays on

Remove wires at tstat Turn switch for furnace off than on.
touch the red wire to the white to simulate a call for heat.
Or Touhc red green and yellow to simulate a call for cool.
If that works get a new thermostat.

SOURCE: Honeywell digital thermostat stopped working

Sounds to me like you have a low voltage short. If the stat had no display until you installed the battery means there was no voltage for the stat to work. Putting the battery in proves the stat works, no motors turning on probably leads to a blown low voltage fuse generally a blade fuse on circuit board in indoor unit. Good Luck

SOURCE: How do I

There is a seam around the edge of the Thermostat , a small screwdriver or butter knife should do the trick , if not then its mounted to a plate on the wall that has 4 corners basically...Gently squeeze the bottom and pull the bottom out , they are pretty sturdy and you shouldn't have a problem,...the wall plate may flex a little while doing this

Sounds like you also have a high efficiency furnace like mine.
Here is a procedure to slow down the number of cycles you are experiencing.
1. press System
2. press and hold buttons 3 and 5 on the bottom of the screen. (there should be 7 buttons displayed)
3. set code to 240
4. change setting to 3 for 3 cycles per hour. (your thermostat probably shows a higher number, probably 5? That is why your unit is cycling so often).

We have a Honeywell Digital thermosat. We just put brand new batteries in it and it is still showing lo battery.


on most of honeywell units if you pull the face of the thermostat off there is a reset button you can puch and reset try this.... if it does not have a reset remove the red power wire on the "r" terminal and if you have a wire hooked to the "c" terminal remove it at same time ///take batteries out prior to doing this and it will reset the program in thermostat... if the display comes back again with the lo battery the thermostat internally has a issue...good luck

Honeywell TH8320u Vision Pro 8000 Digital keeps calling for heat


Hi,
If the thermostat is not over shooting the temperature than don't worry about it.
These thermostats are very sensitive and will turn the heat back on even before the degrees drop on the display. Often they will shut down before the display changes also. You can change the sensitivity of the thermpstat if you read the directions and change the cycles per hour to a less number. There is an installers program in there that you need to push a combiunation of buttons to get too. The instructions tell you how to do that also.

Hopefully you did not throw away the instruction manual for your t-stat.. :-)
