Question about Honeywell Programmable Thermostat Heater
The thermostat is not advancing through each program. It is stuck on program one, even though the time is changing on the thermostat.
After several months of calling Honeywell (actually someone in India), I found what seems to be the solution. I think I became such a pest (they had a lot of complains from me in their record) that they put me on hold and called someone at Honeywell Corp. The solution was to "reset the microchip". You do this by holding down the "Mode" button and while holding it down, take the batteries out for a couple of seconds (still holding down the Mode button) and then put the batteries back in and release the Mode button. 10 days have passed and it has been working perfectly. Hope this doesn'f jinx it! Good luck.

Ensure both your regular time setting and your programmed time settings have the correct AM/PM setting. If not, the displays will be different from what you think they should be.
If you're using the same programming for the entire week, ensure you've programmed it accordingly by pressing the "DAY" button for 3 sec. during the programming to include Sat.& Sun. Otherwise it will be default to a 5 day cycle.
Anytime you press the Mode button after you've exited the programming, it will revert to a "hold". This means you'll have to re-program to revert to program control---hit the exit button only once.

SOLUTION #1 worked for me - my time on the thermostat was correct, the wiring was correct, and my programming was fine, but the a/c wouldn't come on even though the temp was set to 70, it was already at 77!
BUT - you don't need to hold down MODE after you take the batteries out; what you should do is hold MODE when the take them out - LEAVE THE BATTERIES OUT FOR 20-30 MIN, so the thermostat completely loses all electricity - then hold MODE when you put the batteries back in; wait 5 min and it should work

These new thermostat can be confusing to say the least. On yours does the display say HOLD on the screen? If so, then the program override is set, thus negating the program.
