i checked all the resistances everything seems to be working fine but now i got a mail from biasi saying i cant connect a 240V thermostat to this model could this be true?
yes that i understood but when i opened the boiler, 1 was connected to neutral and 3 went to pcb now i dont know where to wire 1 on pcb or i leave the 1 empty i think it has to go somwhere.
HMMM it was wired like that with an old thermostat and it worked fine as for the manual if i check at the diagram the blue wire as i understand as the neutral comes out of electric suply to external control correct me if i m wrong
