Access the Menu: Once the thermostat is off, press and hold the center button on the device. This will bring up the main menu. Navigate to Reset Option: Use the arrow buttons to navigate to the “Settings” option, then select “Reset” from the list. Select Factory Reset: You will see a few reset options.
For the Honeywell Home app: Select the thermostat, press the Schedule icon, choose Options, then Turn Schedule Off. For the 8000 series thermostat: Press the "Sched" button, select "Edit," choose the days and period to clear, then select Cancel Period to clear the schedule.
Turn your thermostat “off”, then flip the related circuit breaker “off”. Wait 30 seconds, then turn the breaker back “on,” then the thermostat. Set the thermostat to hot or cold, whichever you prefer, and your desired temperature. This should effectively reset it.
Check the Power Source: Ensure your thermostat is receiving power. Replace batteries if your model requires them or check the circuit breaker if it's hardwired. Inspect the Wiring: Over time, wiring can degrade. Inspect for any loose connections or signs of wear.
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.”
Switch the batteries.
Remove the batteries, then install them backwards. Leave them that way for at least five seconds, then take the batteries out and put them back in the correct position. Close the battery door and check if the display is back–if it is, then you've just reset the thermostat successfully.
If you have a manual thermostat, setting the temperature on your Honeywell thermostat is simple. All you need to do is to press the up and down buttons to set the temperature. The temperature you set will stay until you change the temperature again.
By pressing “Hold”, your thermostat will lock in the temperature it's currently at until you change it again. When you are ready for your normal schedule to resume, simply press the “Run” button and return to your typical programming.
To completely bypass all programming, simply press the HOLD button once. HOLD will appear in the display. For as long as HOLD appears in the display the thermostat will not change the set-point temperature unless you adjust it yourself with the up or down arrow buttons.
To reset the device so that the pump priming cycle can be entered, press and hold the reset button until the light emitting diode (LED) flashes (approximately 30 seconds).
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.
If your thermostat is set to a temperature regulation mode or has an energy-saving program enabled, it might reset to conserve energy.

Resetting your Honeywell Thermostat can fix common issues like inaccurate temperature readings, scheduling problems, and unresponsive buttons.
Troubleshooting a Programmable Honeywell Thermostat
Put in new batteries; Check the circuit breaker; Check the indoor unit to make sure all the panel doors are closed; Make sure the power is connected to the furnace or air conditioning unit by checking the switch near the indoor unit is up.
One of the most obvious is when the display becomes dim or unresponsive, meaning there is low battery power. This can also signal a dead battery. You may also notice that the temperature in your home is not consistent, or that the thermostat is inaccurately registering the temperature.
Check the configuration of the thermostat to make sure it is controlling the equipment properly. Verify that the thermostat is wired correctly. Make sure all of the wires are secure and in the correct terminals. Make sure the voltages are between 18 and 30 VAC or 20 and 30 VAC depending on the thermostat model.
