Busy saturday today with my build!
I had to wire all the relays with the different power lines, as follow:
12V: brewtroller and expansion boards, n. 10 motorized valves
24V: gas sparks and gas valves
220V: n. 2 march pumps, n. 1 apple airport express, n. 2 air pumps for the bubbler system
Probably in the evolution of the build I'll have to introduce some terminal blocks instead of having such a huge amount of spaghetti in my control panel!
Brewtroller and expansion boards (10 channel relay, 3 channel relay, network interface)
Everything seems to fit in the control panel enclosure
The 2 left switches are for the gas (HLT on top and Boil Kettle on bottom)
The 10 center switches are for valves 1-10
The 2 right switches are for pumps 1 and 2
Ports side view
Tomorrow some final adjustments and if everything will be ok, some tests and calibrations (temperature probes and volume measurement)
