Question about Air Conditioners

1 Answer

Honeywell VisionPro 8000 cycles between Hot and Cold all day.

I have 4 Honeywell VisionPro 8000 controllers controlling 4 commercial HVAC units.
They are all programmed to AUTO setting and cool above 72F and Heat below 69F. 3 of them work well but one of them, for the last several months, constantly switches from hot to cold and back. It basically keeps heating till well past 69, actually way up to 76 or more, then the AC comes on and cools down to 65 or below when the heating starts again. Is this something that can be fixed easily or is this likely to be something requiring warranty service?

Yes it sound like either they wired it wrong or when theywent and configured the settings this obe did not take to the configuration correctly. Have the contractor come back and do the job correctly or replace the thermostat. Thinks for using Fixya

Why is screen showing EE and will not respond to touch?


The replacement batteries could be defective or installed incorrectly. Also, the thermostat could have been reinstalled incorrectly after battery replacement.

Is there a battery in the t8000c thermostat the screen is blank


There should be a couple of AAA batts in it. Grab all 4 corners and pull straight out & off the mounting plate. If no batteries are installed it is hard wired & the problem is at the air handler(blown blade fuse or open transformer winding). When you reinstall batteries make sure there is no corrosion. And careful when you put the tstat back onto the base. There are some small pins that need to align with its holes/terminals. Honeywell has a great 1-800 support #. Should be on the tstat.

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

I have a Carrier Weathermaker SX HVAC unit with a Honeywell thermostat. Even if the thermostat is turned "off", my fan keeps blowing!


Hello, usually this is a sign of a bad blower relay on the intergrated control board. The only option is to replace the control board.

My visonpro Honeywell 8000 digital thermostat's screen is locked and I can't unlock it


Push the System button, then in the bottom row of empty buttons, press the middle buttton for 4 seconds. The display will change, showing system codes on left and that code's setting on the right.
Choose 670, and option 0 opens it up completely, option 1 locks it partially. You should not try to override settings the HVAC/Building admin has set for you, in case you are trying to defeat their control.
