Could anybody give me the pinouts from the M11 port on a 2002 linea 28 boiler please I know pin 2 is N (blue) but I dont know pins 1 and 3? Also is the 240v applied or dropped to operate the divertor valve in either heating or DHW? :?
I am having a problem with the pressure in my CH system,with the pressure set to 1 bar when cold, I turn on my heating and the pressure gradually increases to 3 bar and above! this is causing the release valve to open and reduce the pressure in my system once the heating is turned off! locking...
