Hi everyone, I've recently replaced the pcb on my ferroli he31c boiler and its since come up with an F37 code (system pressure switch). The thing is when I put my old pcb back in it goes through its sequences etc and although doesnt ignite no error comes up. I've been having problems with relays on the board hence me changing it. Can you tell me if its a pcb parameter setting that needs to be changed so it recognizes the switch. If so do you have any ideas which setting needs to be changed.
Many thanks in advance for your help regarding this
