I bought the same PID that you used and am following your diagram but was unsure which ports on the PID I connect to. I see that on the boil has 4 ports, HLT and Mash have 12 ports. I was hoping you could explain this a little more. Thanks!

Here is how I’ve connected the PID’S:

Boil PID:

– Port 9 and 10 = hot and neutral
– Port 6 and 7 = going to the boil SSR (make sure not mixing up polarisation + and -)

Mash PID:

– Port 9 and 10 = hot and neutral
– Port 3 = going to XLR connector (pin number 2)
– Port 4 and 5 = going to XLR connector (pin number 1,3). the 2 wires are interchangeable.

HLT PID:

– Port 9 and 10 = hot and neutral
– run a jumper wire from the hot port (either 9 or 10) to port 12. (thats for the alarm relay)
– Port 11= run the hot wire to the alarm switch
– Port 6 and 8 = going to the HLT SSR (make sure not mixing up polarisation + and -)
– Port 3 = going to XLR connector (pin number 2)
– Port 4 and 5 = going to XLR connector (pin number 1,3). the 2 wires are interchangeable.
