Temperatures fluctuations

Post by bcrawfo2 »

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?

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

That was it i had all my ac grounds tied together and all my dc grounds tied together (separately). I hadnt tied them together. All better now
