Let's try resetting a Honeywell Thermostat
Power off the thermostat and remove the batteries. Put the batteries in the wrong way, with negative to positive and positive to negative. Wait ten seconds and put them back in the correct way. Your thermostat will be reset to factory settings.
Yes one moment
Done
