If your thermostat does not have a manual reset button, you might be able to perform a reset through the device's software interface. This can typically be done from the settings menu where you'll find an option to restore factory defaults.
Press and hold the 'Set' button. Simultaneously press the reset button with a paperclip. Hold for 5 seconds and release. Check for programming errors and consult the manual for troubleshooting tips if issues persist.

A bad thermostat can be detected when your AC or furnace is not turning on, your HVAC systems are not turning off, the thermostat not responding, your HVAC system is short-cycling, the room temperature not matching the temperature displayed on the thermostat, and the programmed setting resetting themselves.
Switch the thermostat to the off position. Locate the breaker that powers your HVAC system and turn it off. Wait 30 seconds and turn the breaker back on. Turn your thermostat back on and confirm it has reset properly.

Restart Your Honeywell Thermostats
It might be helpful to set it to “off,” and then back to “on” again to trigger the restart. Depress and hold the Menu button down for 5 seconds. Count to five to ensure the unit has the proper time to recognize the command. Scroll though the digital menu and select “Reset.”
Using the “hold” function on your system means you can suspend the program if you'll be away from home for a while, such as while you're on vacation. This means you can tell your HVAC to stay put at a specific temperature to keep your pipes from freezing in winter but as warm as you want it to be for comfort.
