Goodman & Honeywell Vision Pro Short Cycling


Hi Everyone,

I am just wondering if someone can let me know if there is a mult-speed setting on the honeywell Vision Pro 8000. I have also read a few issue of people's furnaces short cycling with this thermostat. Just wondering how to resolve this?

My current furnace is running every 15min to 20min. When I look at the thermostat it says 23 and my house is at 23.

Lastly for a Single-Stage, Mutli-speed 91 efficent furnace 115,000 btu what setting should I be using on the Honeywell

Appreciate the help
Thanks Terry

And if its already at 3. Go to 2.

You can have short cycling when your furnace is oversized.

I have 2 of thes stats.
The short cycling problem is due to the swing of 1 degree which is not adjustable....per Honeywell.
They do hold room temp well.
I replaced one of them with a RiteTemp 8085C which has an adjustable swing. I set it at 2 degrees and the short cycle was gone.

Best Wishes for Happy and Warm Holidays

Only time you have trouble with the Vision Pro 8000 or IAQ short cycling after the CPH is set right. Is on oversized systems.

Glad you got it taken care of.

I'm just trying to get an answer to a question that Goodman should have in the install manual. The installer didn't have the answer.
I was blown off by the Pro's so I came here.
I'm an old Civil/Mechanical engineer....I can make the adjustment necessary to set the blower output.
Someone has the answer to this....they have sold hundreds of these 2 ton systems.
Thanks anyway,
Xander

Goodman has poor documentation on how to set those smaller high efficiency systems up. And many people don't take the courses on how to install them.
