How to Reset WiFi on Honeywell Thermostat

This post gives reset WiFi instructions for a typical Honeywell thermostat. For most t-stats, the best way to reset the WiFi settings on them is to just do a factory default reset, and so, that’s what we’ll do here.  We demonstrate this on the RTH9580WF wireless Honeywell thermostat. This method does the following.

  • First of all, it clears out all custom settings.
  • Then, it resets the WiFi network.
  • Finally, it restores the WiFi thermostat back to factory default state.

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





We suggest these directions when fixing problems. Resetting the WiFi in this way also cuts the chance that faulty settings are causing the t-stat to act funny.

But after doing this, 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. Resetting returns the Honeywell WiFi 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 How to Reset WiFi on Honeywell Thermostat

Get your Manual

Before restoring to factory default settings, gather your t-stat manual that shipped with it. Or, find it online at Honeywell’s web site.

Write Down the Current Thermostat Program Schedule

Jot the current daily program schedule currently stored in the t-stat. Do this if you’ve changed it from the default schedule.

Record any other Settings you’ve Changed from Default

Then, run down through the menus in the t-stat. Jot 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.
