How to Unlock Honeywell Smart Thermostat

Many Honeywell smart thermostats 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, the t-stat asks you to enter this secret code.  Once you do that, you again have full control over settings such as WiFi, temperature, scheduling, and other HVAC details.  So here we explain How to Unlock Honeywell Smart Thermostat.  Explicitly, we show this on the RTH9580WF programmable smart thermostat.

This demo begins with our t-stat locked.  We also assume that the t-stat is showing its  Home   page.

How to Unlock Honeywell Smart Thermostat: 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 is in lock mode, the   MENU  button still works.

This then displays the main menu page.  Keep in mind that 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 thermostat then shows the   Please enter your password   prompt screen.

3. Enter the Pass Code

Then enter the code you assigned when you set up the password.  In this scenario, our security code was 2752.  So, we used the up and down arrows above and below each number position. With these, we can enter the correct digit for 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 How to Unlock Honeywell Smart Thermostat

So tap   Done   once you punch in the pass code. The thermostat then shows the  Security Settings  screen.

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

Then this again 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.

7. Tap the   Previous Menu   Button

Then this returns you to the  main menu as shown next.  Note that all menu items are now available.  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.

So if you do see these, then you have successfully unlocked your thermostat.

8. Done with How to Unlock Honeywell Smart Thermostat !

Finally, you are now free to change any setting you wish on the main menu.  Thermostat unlocking is now complete.
