Hi,
Trying to work out why the circulator pump does not work on CH mode. It works ok on DHW mode but won't go whilst the boiler is on Central Heating. There are 4 separate relays on the board which complicate things greatly, can these be changed or could it be something else?
Remember the burner WORKS in CH mode but pump does not?
