How to Reset Honeywell Thermostat Settings

A reset Honeywell thermostat settings erases all user changed settings.  Resetting also removes lock screen passwords and screen color changes et al. Resetting restores this Honeywell RTH9580WF touchscreen thermostat to factory default condition.  You reset by following the routine below. We suggest this reset Honeywell thermostat settings action when fixing smart thermostat issues as well.  Why?  Because resetting rules out the likelihood that wrong settings are causing the RTH9580WF to act strangely.  The problem often goes away after reset.

Keep in mind though, that after reset, the RTH9580WF forgets any user added settings. So you’ll have to enter your WiFi and furnace info again. Also, the RTH9580WF gets rid of custom program schedules you’ve entered.  Thus, resetting returns the RTH9580WF to the default daily heating and cooling schedules. So again, you may need to set them again to your specific needs, if you have any.
