I'm speccing a job in a pub, replace 2 boilers. Old system is simple, 1 or 2 boilers depending how warm you want it, one big pump and a few switches,
New system is less so. 2 boilers, with a pump each (A and B) and a third pump (C)
2 timeswitches, one for each boiler
1 boiler needs A and C
1 boiler needs B and C
2 boilers need A,B and C
this should be simple, except the new boilers don't have pump over run so the boilers and the pumps are connected to the time switches, so if I just wire it all together then both boilers and all 3 pumps will run all the time, but I need to be able to control the boilers separately, i'm guessing I need a relay or 2?
Ideally something commercially made, I'm thinking DIN rail mount in a nice box
Don't mind the wiring, just not sure how to wire it all up
