This post gives the Honeywell Home thermostat reset procedure. We show this on the RTH9580WF smart t-stat, and this reset method does the following.
-
- First, it clears out all custom settings.
- Then, it resets the WiFi network the thermostat connects to, to none.
- Lastly, it restores the thermostat to factory default state.
So, follow the steps below, to reset most any Honeywell Home thermostat.
We suggest these directions when fixing network connect problems, because resetting the thermostat cuts the odds that faulty settings are causing the t-stat to act funny.
But note that after resetting, the t-stat 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, WiFi resetting returns the Honeywell thermostat to the built-in heating and cooling routines. So again, you might want to adjust them again for to your specific needs.
Honeywell Home Thermostat Reset : Before You Begin
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.
Record the Current Thermostat Program Schedule
Jot down the current daily program schedule 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.
