The function Pump groups has been created for this. You use a pump group if your radiators are connected to a circulation pump that has to heat 1 or more rooms, such as with underfloor heating.
To be able to use a pump group, first connect a Plugwise Plug to the circulation pump (s). Then set the Plug as a central "circulation pump". After this you can compose the pump group: Indicate which Plugwise zone displays (Lisa) and whether radiator knobs (Tom or Floor) depend on the heat from the circulation pump.
With a pump group, the circulation pump will switch on when you turn up the heating for one of the rooms and off again when the temperature is (almost) reached.
Pay attention! Have you only installed a thermostat in a room, but no Plugwise radiator button? Make sure that the radiator knob on the heater is always open.
