This post gives the resetting Honeywell home thermostat procedure. We show this on the RTH9580WF programmable thermostat, and this method does the following.
-
- First, it erases out all custom settings.
- Then, it resets the network the thermostat connects to to none.
- Finally, it restores the thermostat back to factory default state.
So, follow the steps below, for Resetting most any Honeywell smart thermostat.
We recommend these directions when fixing network connect problems, because Resetting cuts the chance that faulty settings are causing the t-stat to act funny.
But note that after Resetting, the unit forgets any programmed settings. So you must re enter your WiFi network name and password again. Also, your custom schedules, if any, will disappear as well. As mentioned, Resetting returns the thermostat to the built-in heating and cooling routines. So again, you might want to adjust them again for to your specific needs.
Resetting Honeywell Home Thermostat: Before You Start
Get your Thermostat Manual
Before restoring to factory default settings, gather your t-stat manual that shipped with it. Or, find that document online at Honeywell’s web site.
Write Down the Current Thermostat Program Schedule
Write down the current daily program schedule currently stored in the t-stat. Do this if you’ve changed it from the default schedule. If you haven’t changed this since the last time you reset the thermostat, then skip this step.
Record Any Other Settings you’ve Changed from Default
Then, run down through the menus in the t-stat, jotting down any settings that you changed prior that let the Honeywell WiFi thermostat work with your furnace. These include filter-change reminders, WiFi network connection info, system type, t-stat name, location, et al.
