If your manualy setting the program and it kicks itself off, then your therm is bad, look for your warranty paperwork, or call the distributer and give them model and serial, they can point you in the right direction. If your setting a temp and not manualy holding, then it will set back by default. Check your other settings, ensure they work as well..

Can I manually override a Honeywell 69-0940-2? I don't want to program it. Just want to turn the air on for a few hours to cool the house. Thanks


That thermostat cannot be overridden to remove the seven day schedule. If you select you desired mode (HEAT or COOL) using the SYSTEM button, then using the UP or DOWN arrows next to the screen to set your desired temperature, finally press the HOLD TEMP button to lock that setting in. It should stay there until you press hold temp again, make a temperature set point adjustment, or a loss of power. These thermostats are kinda complicated for the everyday user and were usually installed in commercial buildings where the end user's access was limited. Hope this helps. I also provided a link to the Honeywell Manual. http://www.transtaracsupply.com/pdf/t8600manuel.pdf

Why does my Honeywell thermostat state temporarily set at 68 degrees? A few days later, it will be set at 62 degrees without anyone touching the thermostat?


It's a programmable thermostat. When you change the temperature, it will say temporary until the next programmed schedule starts or a set amount of time. You will have to program the thermostat to the correct temp settings you wish to have, or you can push "HOLD" after changing the temp to make it stay at that set point. Hope this helps!

Trying to set temp on honeywell t-stat


I believe what your experiencing is the 75 degrees is the hold temp position...the display then reverts back to the actual room temperature...it doesn't mean the set temperature changed back to 65 degrees. Try to reprogram the thermostat schedules, and try not to use the hold function...just the temporary hold. (which is bumping the programmed temperature up or down until the next programmed period)

My Honeywell Thermostat won't stay at the temp that I set it at!


You are likely running a schedule. When you go to tstat and change the temp it is a temporary setting that will expire in a given amount of time. 1, 2 3 hours etc. "HOLD" can sometimes bypass the schedule, "RUN" returns to the schedule. Not sure what model tstat you have but you have to exit your schedule.

How do I set the temporary or permanent override feature on the Honeywell RTH2310B model thermostat?


To set the temporary override, press arrows up or down to desired temp. This will keep temperature
at temporary setting for 2 hours then return to programming. To permanent override press MODE button until schedule period number disappears (number inside little house on stat). Then adjust temp with arrows. Press the MODE button again to cancel override and return to programmable.

Non-deletable schedule in VisionPRO TH8000


The thermostat has a function called "Adaptive Intelligent Recovery".

This feature allows the thermostat to learn how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the time you set. For example: Set the Wake time to 6 am, and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6.

You can turn off this function. Download the installation guide at the next link:
http://customer.honeywell.com/honeywell/ProductInfo.aspx/TH8321U1006
and look for funcion number 0530 Adaptive Intelligent Recovery. In this manual you also find the way to do a reset with the function number 0710.

I hope this solves your problem.
