Ive got a fault with this boiler, customer has had new PCB fitted and will only fix boiler, not responsible for pump/valve in airing cupboard.
Im sure the mid position is a Danfoss, which ive never seen, is the wiring on this the same as a Honeywell 4073a ?.
The pump humms fine on 3 speeds.
Can anyone suggest what voltages i should be geting at the wiring centre ?.
