Combi boiler diverter valve - when hot water is on (tap opened) the diaphragm should deflect and move a spindle which makes contact with a micro switch - thus letting the primary hot water (from the primary HE) heat the domestic hot water instead (ia the secondary/plate HE) ... right?
but should there be a flow switch also near the diverter valve, which operates also, or is this just for the temperature? ...
sorry i am trying work out how it works ...
