I have a switch master 805 programmer ,
when i switch it on to just hot water (constant) the pump runs is this right or should it only run when the central heating is on,can some one can tell me where to find a wiring diagram for the switch master 805 and to the pump and room thermostat and the three way motorised valve so i can check that it wired up correctly.
