Last night I decided to move my fermenter out of the chest freezer fermentation chamber. The temp was holding steady at 19.9C before I moved it. I turned off the STC-1000 and unplugged the sensor, then moved the fermenter from inside the freezer to on top of the freezer. I plugged the sensor back on and turned on the STC-1000 and now it was holding steady at 20.6C...
According to the controller moving the fermenter a couple feet raised the temp by 1.3F...
About an hour went by and I heard a *click* from one of the relays in the STC-1000, I look over and the temp shot up to 21.5C. I kept an eye on it and the temp was bouncing all over from 20.6C up to 22.1C. Occasionally it would settle back to 20.6C for a minute or two then start oscillating again.
I turned the controller off overnight because it clearly wasn't going to be reliably holding the temperature. I turned it on again this morning and the temp held steady at 19.8C for about an hour before I turned it off and left for work.
My temp probe is ran through the blowoff tube and dangles down into the wort right in the middle. I did calibrate it with ice water and ended up with a -0.7C calibration value. I've been using it like this for a few batches now without issues. I ordered 5 more temp probes from Digi-Key to see if perhaps the probe is the problem.
Anyone had a similar problem?
