How did you set the parameters for the pcb to match the boiler. I have 35kw combi but can’t get the parameters to flash from 1-12 when I follow the instructions

What temperature would you say the boiler should sit at idle? Mine is set to 65c would you expect this to drop to say 30/40 when I'm not using jt for heating or water ?

FF fault is the board I recently changed one and worked fine after. They aren't cheap at £271
