Hi guys, can anyone help,
i have a alpha 240x, and the dhw was passing over to the heating, changed the domestic diaphram and the full kit on the c.h. side. now when you run the boiler on ch demand , the pump runs the diaphram lifts but the boiler doesent fire, if you lift the dhw micro sw. the boiler fires and the ch starts to flow, let the sw go and the pump continues but the boiler shuts down, however the ch diaphram stays on demand with the clock on or off, if you now open the dhw the boiler fires and the dhw is hot so the water is now diverting as to the demand.
i,mm thinking the differential pressure sensor but ??
greatfull for any sugestions
