I have a Johnson Control A419 hooked to a chest freezer.
I've done trial runs at different temperatures and it has worked great. Now, today, when I finally try to put it to use for brewing, it is not cooperating.
I earlier today, I had the set point at 63 with a differential of 1 and I got down to 56 before I shut it off. I reset it at 65 with a differential of 2 and it held pretty close to 65. I knocked it back to 63, differential still at 2, and it was just reading 58 degrees.
any clues as to what I'm doing wrong?
any help is greatly appreciated.
thank you.
