Initial PID setup

Hi All,

I have finished the hardware setup of a 373Ltr residential fridge with a Mangrove Jacks 240v 25w heat pad with 60Ltr fermentor

I am ready to start testing with just water initially while tuning in the PID. What numbers are people using for Kp, Ti and Td in a similar setup? I am not sure where to start.

Cheers.
