Many Honeywell Home Thermostat models, have a lock screen mode. This keeps anyone from messing with t-stat settings without first putting in a password. You set this pass code when locking your t-stat. Then, to unlock it, it prompts you to enter this secret code. And doing so again grants full access to settings. These include WiFi, temperature, scheduling, and other HVAC settings. So here we give instructions on Unlocking Honeywell Home Thermostat. We show this on the RTH9580WF programmable WiFi thermostat.
This demo begins with our t-stat locked. We also assume that the t-stat is showing its Home page.
Unlocking Honeywell Home Thermostat Instructions, Step by Step
1. On the Home Screen, Tap the MENU Option
Find the MENU button in top right corner of that page. Note that even when the t-stat in lock mode, the MENU button still works.
This then displays the main menu page. But you might have to press the down-arrow button several times to reach the Security Settings option.
The next picture shows the main menu, already scrolled, to show the Security Settings item.
2. Tap the Security Settings Option
A password protected Honeywell Home Thermostat then shows the Please enter your password prompt screen, as shown next.
3. Enter the Pass Code
Enter the code you assigned when you created the password. In this scenario, our security code is 2752. So, we enter the correct digit for each slot with the UP and DOWN arrows above and below each position.
Again, Unlocking allows access to the Security Settings menu. There you can either fully unlock, partially lock, or remove the password altogether.
4. Press the Done Button to Continue with Unlocking your Honeywell Home Thermostat
Tap Done once you’ve punched in the pass code, the thermostat then shows the Security Settings screen, as shown next.
From here, you could choose either of the following.
-
- Delete the Security Settings password.
- Change the lock mode while leaving the existing password in place.
You need not remove the password to unlock the thermostat. Nor must you change the lock mode in order to remove the password.
5. Tap the Change Lock Mode Button
This then displays the Change Lock Mode screen, that shows the Fully Locked option highlighted in blue.
6. Tap the Unlocked Button
This unlocks the thermostat and returns you to the Security Settings screen, as shown next.
7. Tap the Previous Menu Button
So this returns you to the main menu. Note that all menu items are now available. So verify this by scrolling down through them. If you see the following items such as…
-
- Create Schedule.
- Color Themes.
- Preferences.
- Temporary Schedule Changes.
- WiFi Setup.
- System Setup.
If you do see these, then you have indeed unlocked your Honeywell Home Thermostat.
8. Done with Unlocking Honeywell Home Thermostat Instructions !
