Vokera 80SP question?
The boiler works fine both HW and CH, but the operation sequence seems not quite right. When CH is selected, it fires up as soon as the main power is switched on without demand of both HW and Ch( taps closed, radiators in the "0" position ), I see the pin pushing out on the flow microswith, it must be this operation that is trigging the firing up. The pin back to the orignal position, when the mian power supply is switched off. Is something wrong with the wiring?
