How to Clear Settings on Honeywell Thermostat

Shows how to clear settings on Honeywell thermostat.  Here, we cover doing this on a Honeywell RTH9580WF model.  But other models with a screen work similarly

At any rate, you clear these settings by resetting the thermostat.  This also clears lock screen passwords and screen color customizations et al.

Clearing settings restores this Honeywell thermostat to factory default condition.  We recommend this action when fixing thermostat issues as well.  Why?  Because wiping settings rules out the probability that wrong settings are making the RTH9580WF act weird.  The problem often disappears after you clear the settings.

Remember however that after you clear the settings, the RTH9580WF forgets any settings you changed from default. So you’ll have to enter your WiFi and furnace parameters again.

Also, the thermostat clears all custom program schedules.  Thus, settings clearing returns the unit to the default daily heating and cooling schedules. So again,  program these in again to fit your specific needs, if any.

How to Clear Settings on Honeywell Thermostat: Before you Start

Before clearing out the thermostat, get the RTH9580WF booklet. The RTH9580WF original package includes this pamphlet.  But if you’ve lost yours, find it online at Honeywell’s web site.

Write down the program in the RTH9580WF if you’ve changed it from the default program.

Then, run through the menus. Record any settings that you’ve changed for your heating / cooling systems. These include filter-change reminders, fan mode, WiFi network data, system type, thermostat name, location, et al.

So DO NOT do this until you’ve recorded this data somewhere.  Don’t procede until you’re sure that you can set up the thermostat with your furnace / HVAC system details again. Get help from a climate control worker if unsure.
