Honeywell RTH9580WF Thermostat Reset Instructions

These Honeywell Thermostat reset instructions (RTH9580WF model) clear all user changed settings in this thermostat.  Resetting also erases lock screen passwords and screen color changes et al. Resetting restores it 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 t-stat 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.

Before Honeywell Thermostat Reset on the RTH9580WF Smart Thermostat

Before resetting, get the RTH9580WF booklet. The RTH9580WF 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.
