Honeywell Thermostat Reset WiFi Instructions

This post gives Honeywell thermostat reset WiFi instructions. We show this on the RTH9580WF smart t-stat, and this WiFi reset method does the following.

  • First, it erases out all custom settings.
  • Then, it resets the WiFi network the thermostat connects to to none.
  • Finally, it restores the WiFi thermostat back to factory default state.

So, follow the steps below, to reset the WiFi on most any Honeywell wireless thermostat.

We recommend these directions when fixing network connect problems, because resetting the thermostat cuts the chance that faulty settings are causing the t-stat to act funny.





But note that after resettting, 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, 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.

Before you Start with Honeywell Thermostat Reset WiFi Instructions

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.
