I have a Honeywell Thermostat 32207445-001 and the screen is blank. The cover indicates it may be a security feature. How do I reset the unit?

Did you try turning off the power to the unit. Also is there a lock on the thermostat. Check manual maybe you need to hold certain buttons to unlock.

My thermostat is not working. It might be locked. It's blinking with all of the information it holds flashing on the screen. The part number is: tstatccnhp01-c My heat is no longer working. Can you...

  1. 1 Unlock a partially locked screen by pressing any locked key, which will bring up the "Screen Locked" message. Next press an unlocked key, which will likely be the temperature up and down arrow keys. This will unlock the screen.
  2. 2 Press the "System" key from the home screen. Five blank touch keys, flanked by the "Done" and "Cancel" keys, will appear. Hold down the middle key for about five seconds. The Advanced Settings menu should come up.
  3. 3 Change the User Setup Number, found in the bottom left of the screen, by pressing the middle arrow keys up or down. Set the number to "0670," the universal unlock code.
  4. 4 Turn to the arrow keys on the right side of the screen. Press the keys up or down to change your options. Selecting the number "0" will unlock the screen, while choosing "1" will partially lock it. You can fully lock your screen again by selecting.

Honeywell th8110u1003 touch screen frozen working but cant adjust at all

It sounds "locked". Refer to the installation/setup manual that came with the tstat for information on how to lock and unlock the thermostat.

Display is stuck and won't respond to buttons

Your screen may be locked out. Read instruction on locked screen sometimes people lock it by mistake. All Honeywell tstats are different the way they lock. Push mode and and up and down buttons at the same time. You may have to go into it to change parameters. If this does not work bad Tstat.

Honeywell VisionPro TH8000 touch screen will not allow changes to the schedule. Screen is unlocked and not in cleaning mode

In the set up mode are you sure the lock was not turned on. The set up mode has a different book for the installer. Do you have the book if not check with Honeywell or let me know.
