Question about Heating & Cooling

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

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.

Why is my honeywell 8320r1003 short cycling for hot water heat.I have heat set at 65 degress.cycling 2min,3min,the most is 8min.


Hi Bill, after closing your thermostat, is this correct the situation?
And how far is your thermostat from your baseboard heater, if the baseboard is underneath the stat, you should move the stat elsewhere. Hope this help you find the problem.

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.

My Honeywell chronotherm IV Plus thermostat intermittent problem


The Chrono Therm 3 and 4's were some of the worst products that honeywell has EVER put out. I would suggest switching to the Vision Pro 8000, please consult your local HVAC company for more information regarding the change over.
