Unwanted non-deletable schedule exists.Honeywell VisionPRO TH8000 When moving from Sleep scheduleto Wake schedule former schedules appear even though correct scheduleis placed in memory and is visible as desired schedule for wake mode.Is there any way to purge entire memory and go to default so that I canremove unwanted schedules.

    I have one of the TH8000s and one of the older variety without the touch screen - if not the Model# RTH221B, it's a lookalike (the model number is too small to read - age - poor me).

    Our problem is, we have peak time and off peak time with our electricity provider, so when the peak hours finish at 7PM, the thermostats had already kicked in and were running up our demand charge, not to mention double the KWH rate.

    The TH8000 model was disabled with 530 function set to zero, the other with function 13 set to zero. This worked perfectly and I'm happy to be back in charge of my cooling schedule :-)

    I wouldn't have cared so much if it wasn't for the ridicules 12PM-7PM peak rates down here around Phoenix.

The thermostat has a function called "Adaptive Intelligent Recovery".

This feature allows the thermostat to learn how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the time you set. For example: Set the Wake time to 6 am, and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6.

You can turn off this function. Download the installation guide at the next link:
and look for funcion number 0530 Adaptive Intelligent Recovery. In this manual you also find the way to do a reset with the function number 0710.

I hope this solves your problem.

    I mourn the loss of my old mercury switch thermostat! The electric company talked me in to going with the new and improved programmable thermostat. When the installer programmed a Day/Night schedule for my heat pump, the Adaptive Intelligent Recovery caused my auxillary heat (electric) to come on the estimated time in advance resulting in an approximate $127 increase in my monthly bill (which the company eventually reimbursed). The second service tech who came to investigate the problem explained the adaptive intelligent recovery program (which apparently the first guy didn't know about when I told him I did not want my auxillary heat coming on without my intervention). He programmed it to OFF (program 530 set at "0") and all was well. Then I had a service call for my heater and the service guy "broke" my thermostat and he replaced it but didn't know about program 530. This Link in this answer takes you to the Installer's SETUP information (page 15) and I was able to "turn off" the adaptive intelligent recovery. I'll go with this but there is something to be said for the old mercury switch with a manual control! Thanks for the information!

    In order to turn of the Adaptive Intelligent Recovery, search for the installation manual for your model. Mine was Honeywell model TH6110D, you had to press the fan and up button to get into the menu, and then turn option 13 to 0.

I have a Honeywell VisionPRO IAQ thermostat. Heat won't kick on automatically, thermostat keeps saying 'wait. Can turn system off, back on and works. Is there something I can do to fix it?

Have you tried reseting the system by throwing the breaker waiting a minute then restarting? Turning it off and on at the keypad isn't the same thing. That has happened to me and the program glitched. I'm not sure what is being displayed on the screen, so am not sure what you have done, partially completed a scheduling program, etc. However, I found the manual online.
You can look through it and see if there is something in there you aren't/are doing to keep it from working properly. There is also a 1800 number for assistance from Honeywell if your still stuck. Hope this helps.

Whdoes it mean of wake, return, sleep and leave on honeywell digital thermostat

I believe it means (I assume winter weather in my example):
1. Wake - This is the time you wake up and you would set the temperature at the time you want it then. So, your temperature throughout the night might have been set at 63, and if your "wake" time on the thermostat is set to 6:00 am and 68 degrees, then your system will automatically adjust the temperature setting to 68 degrees at 6:00 am.
2. Leave - This is the time that you would typically leave your house for work. You probably don't need to heat or cool your house that much during this time especially if no one will be there. So, let's say you leave for work at 8:00 am. You would set this time for 8:00 am and 60 degrees.
3. Return - This is the time you get off work. Let's say you get off at 5:00 pm. You would set this time for 5:00 pm and 65 degrees. Then the system will start warming up at 5:00 pm and will be warmer by the time you get home.
4 - Sleep - This is for when you go to bed. Following the example, let's say that you set your temperature while sleeping to 63 degrees at 10:00 pm. Then, the system adjusts at that time and will adjust again as soon as then next parameter is met, which at this point would be the wake time.

This is usually for a Mon - Fri schedule and then a separate one for the weekend.

Right side of i touch screen non-reactive

Perform the under given steps to troubleshoot the issue:

(i) Clean the iPhone screen with the cleaning cloth that came in the box with the iPhone.

(ii) If you have a protective plastic sheet or film on the touchscreen, try removing it because it may be preventing the touchscreen from working properly.

(iii) The current application may not be responding (frozen), press and hold the Home button below the screen for at least 30 seconds, until the application you were using quits.

(iv) If that doesn't work, turn the iPhone off and turn it on again. Press and hold the Sleep/Wake button on the top of the iPhone for 30 seconds until a red slider appears, and then slide the slider. Then press and hold the Sleep/Wake button until the Apple logo appears.

(v) If the iPhone did not turn off, reset the iPhone. Press and hold the Sleep/Wake button and the Home button at the same time for a least 30 seconds, until the Apple logo appears.

If the issue persists then service will be required.

Honeywell 8000 Thermostat relay switch clicking noise.

It's an expensive solution but doable. Look for Honeywell's VisionPro IAQ thermostat. It works much differently than a conventional thermostat and shouldn't click at all make sure it's the 3-wire version.

Can not delete unwanted schedule

Remove the batteries and any power source for 10 minutes. This should go back to factory defaults. Sounds like a stat problem honestly. I would exit the program and change temps manually at all times.

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.
