I've been building up my brewing kit for a few years and last year decided to try a PID controlled HERMS brewery. After a lot of research, development and making I have a brewery but the PID does not seem to operate as expected. My understanding is that it reads the temperature via the sensor (which was supplied with the PID), turns on the output if the temp is lower than the set temp and turns off the output if the temp is higher than the set temp. The output of the PID turns on/off a SSR which controls heating elements. The problem is, when the set temp is reached the heating elements stay on, therefore not giving auto temp control. I've checked my wiring but can't find a problem. Should I be setting up the PID or doing anything with it that I'm not aware of in order for it to operate as expected?
Any guidance would be appreciated.
Cheers.
