Has anyone here heard of this? A friend said he uses this with a window air conditioner to make a walk in cooler. It is supposed to fool the air conditioner control to make it cool down to 32 degrees. There is a web page about it. I did a search for Coolbot. I guess a person would need a lot of room, but from what I read it is considerably cheaper than buying a walk in.

i'd think at that point the condensation in the air conditioner would freeze on the metal coils causing the AC to stop blowing cool air?
John Beere has a build thread where he used a ranco controller on his window unit for his walk-in cooler. Here's the link https://www.homebrewtalk.com/f51/my-latest-project-walk-cooler-11440/index6.html

The entire point is the unit cycles to prevent that.
Bypassing the thermostat on them risks this much more, even with a temp controller. I've seen one of these units in place and it kept it at 37 degrees. Had about 5 inches of insulation surrounding it.
