i need a schematic diagram for a Compact HE COMBI BOILER, i am adding a new control timer. There are four black wires coming from a unit labeled CN1, this is the internal boiler time clock, the manual only shows two wires connected in series with the thermostat. What are the other two black wires for? thanks
