Lost directions to program a thermostat

It's possible you have a lot of dust build up inside the stat. If it has batteries remove face from wall and blow out. Take outside to see if temp will change. Plug the hole in the wall where the wire comes through. If all fails, replace. Turn power off, take wiring picture, replace, turn power on. Good Luck!!

Right below the w setting on the base plate is the o/b connection. Put the O wire in this slot. During the initial test for heat and cool, the bias for cool for function 2 is 0 and for heat it is 1. To reach the programming press fan and Up arrow. Press next to reach function 2. Be aware the the O wire is energized and operates the reversing valve. Some manufacturers energizes the reversing valve to go into cooling, and some leave it deenergized to be in cooling. Select either 0 or 1 to make the system perform in the correct mode.
Hope this helps.

What model is it? example pro 5000, 6000, 8000 ext.

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.. :-)

Heatman101

get an external thermastat installed and check the internal limit thermostat.

They will work, most zone controls only require the use of 1H/1C thermostats, the system stages and functions are controlled by the board itself.

It sounds like the fan relay in the stat itself is not closing when you make the switch over. If you have had the stat for less then 5 years it is covered. Honeywell has a full 5 year warranty on their focus pro stats, and would replace it free of charge.

most likely a bad tstat i would replace I recommend honeywell focus pro 6000

the honeywell is just a thermostat.my guess is the capacitor went out in the condenser when you lost power.turn the temp down on the thermostat and hit the hold button.....if it does not cool,call a service tech.good luck!
