I think I may have made an error. I recently bought one of these things - the CH54 model - off eBay, for $10.30 plus about $5 shipping. I was all proud of myself for getting it so cheap, but, after reviewing this thread, I re-read the posting on eBay and saw that the relays were only rated for 5A. Uh oh. If I wired this thing up to a keezer, I might burn the house down, yes? Do I need to go back to the drawing board and buy a different model? If so, it's a pity; I think the one I got displays in Fahrenheit, which I would have appreciated.
I don't even have the chest freezer yet, so I'm not in a hurry (well, I am, but I'm trying to be patient)... I hope to split an extension cord and mount the unit to the keezer collar, so I can see the display from the front of the keezer. I've seen pics on this board where people have done that, but I haven't seen anybody's in-depth build on how they mounted/ran wires. I did try searching... If someone has detailed such a build, I'd very much appreciate a link. Thanks in advance!
FWIW, the model I got will only control heating OR cooling at any given time. That's fine for me, since I'm in Houston and don't need to heat anything beer-related.
