I'm currently collecting the parts needed for building a new HERMS system with the following criterias:
3 26.5 gallons kettles: Hlt, MT, Boil kettle
2 gas jet burners for Hlt and boil kettle
wort recirculating inside the HLt from the MT
2 March pumps
1 counterflow cooler for wort from the boiling kettle to the fermenter after the boiling time
everything will be managed by the brewtroller microcontroller with the 3 relays and the 16 relays boards.
I'm quite stuck on planning the correct water/wort and gas solenoid valves number and placement among one kettle and the other, in order to automate all the HERMS process.
Is there anybody with an already done similar project that could be so nice to share it here?
Thanks and cheers!
