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.

Honeywell VisionPRO IAQ thermostat. No back light. Screen shows characters, but dim. When touched, back light fails to work. All other systems function okay.


this control has an option for back light display in the set up menu. if it has never worked this may be the problem. if it did work then quit you should replace the t-stat. there are many different models as they have advanced over the years. this is a great control. see if you can find the set up manual

Try the screen button and clean your screen in the given time.
also try honeywell.com/yourhome and use the contact us. They will try to walk you through and fix the problem as an ac company will usually just try to sell you another. These are not cheap stats I use one myself, I've have mine for years. I know it isn't much but hope this puts you in the right direction.

Mystery message "wait" appears above "following schedule" display line on our Th8000. Ac does not come on even when temperature is in range. Fan operates ok. Is "wait" setting one I can reset? Maybe a compressor issue rather than thermostat? Thanks

Same problem, backlight on all the time


http://www.ntsupply.com/files/products/VP8000TechData.pdf
check out this website
if this is the touch screen tstat you have to enter installer setup
touch the SYSTEM button once
hold down what is usually the HOLD and SCREEN keys touch both keys at the same time
(hold the two blank keys on either side of the center key at the bottom)
this will bring you into the setup
BE VERY CAREFUL WHAT YOU CHANGE THIS COULD EASILY SCREW UP YOUR SETTINGS
change where the numboer is 0120 to 0280 and change 1 to 0 then hit done this should fix it:)

Non-deletable schedule in VisionPRO TH8000


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:
http://customer.honeywell.com/honeywell/ProductInfo.aspx/TH8321U1006
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.
