So I brewed a Pilsner this past Saturday, and placed my fermentor (bucket) into my freezer that has my new Johnson (analog) control.
I put my brewing thermometer in the freezer to measure air temp (on top of the bucket), and taped the probe to the bucket with some Reflectix insulation on the outside of the probe, and the probe against the bucket wall.
The probe kept coming off the bucket, so the control was actually regulating the air temp of the freezer for awhile. While I have my control set to 50F, the air temp was closer to 48F, so I set the control to 52F.
Yesterday, I finally got the Reflectix and probe to stay on the bucket with the help of a couple of belts.
This morning, with the control still set to 52F, the thermometer measured the air temp at around 44F.
So I guess my question is, is this normal? I don't see any signs of fermentation yet, but I suppose the bucket could be warm enough to make the controller work hard enough to get the air temp to 44F?
