I have seven sensors on my bcs and they all fluctate several degrees constantly. In the course of 15 seconds they might go shift up/down almost two degrees (a total rang of almost four degrees). This isn’t too bad at mash temps but gets to be a problem at fermentation temps when i am cycling pumps.
Any ideas?

Re: Temperatures fluctuations
Sounds like you don't have a ground jumper between the BCS ground (negative) and earth ground.
