How to Reset a Honeywell Home T6R-HW Thermostat

Step-by-step fix guide | Honeywell Home heating controls

Try this first — Use the smallest reset that fixes your problem: the user menu’s RESET option can reset just the schedule, Wi-Fi or HomeKit to factory default settings.

This guide is for Honeywell Home T6R-HW owners who want to reset the thermostat. It follows the T6/T6R user guide and the T6R installation guide from Resideo, which makes Honeywell Home products.

What This Problem Means

Resideo’s guides list two reset menus on the T6R. The user menu has a RESET option for the schedule, Wi-Fi or HomeKit. The advanced menu, opened with a 5-second press, has a RESET option that also includes a full factory reset.

Common Symptoms

  • The heating schedule needs to start again from scratch
  • Wi-Fi settings need clearing before you set up again
  • HomeKit needs setting up again
  • You want the thermostat back to its factory settings

Safe Checks You Can Try

1. Choose the reset you need

The user menu RESET resets the schedule, Wi-Fi or HomeKit to factory default settings. The advanced menu RESET covers factory, schedule, Wi-Fi and HomeKit reset.

2. Reset the schedule, Wi-Fi or HomeKit

In the thermostat’s user menu, choose RESET, then pick the schedule, Wi-Fi or HomeKit option.

3. Open the advanced menu for a factory reset

This menu is in the installation guide Resideo writes for installers, so if you aren’t sure, ask your installer before a full factory reset. On the thermostat, press and hold the icon for 5 seconds to access the advanced menu; the icon is pictured in Resideo’s T6R installation guide.

4. Choose RESET in the advanced menu

The advanced menu’s RESET option offers factory, schedule, Wi-Fi and HomeKit reset. Pick the one you need.

5. Set up again afterwards

If the thermostat shows WIFI NOT CONFIGURED after a reset, Resideo says to add it in the app: see the T6R-HW Wi-Fi guide for Resideo’s app steps.

Resideo’s guides don’t say whether a factory reset clears the receiver binding. If the thermostat shows NO RECEIVER BOX BINDING afterwards, see the rebinding guide.
