You can let Adam HA switch a circulation pump using a switchable plug and the Pump groups function.

You use a pump group when underfloor heating or radiators depend on a circulation pump that supplies heat to one or more rooms. Adam then automatically switches the pump on as soon as there is a heat demand from a linked room.

What do you need?

You need:

  • an Adam HA;

  • a suitable switchable plug, such as a Plugwise Plug or Aqara Plug;

  • a circulation pump that may be switched on and off via this plug;

  • one or more rooms that depend on this circulation pump.

Steps

  1. Connect the plug to the circulation pump
    Insert the Plugwise Plug or Aqara Plug into the wall socket and connect the circulation pump to this plug.

  2. Connect the plug to Adam HA
    In the app, go to:

    Menu > Layout > Devices

    Add a new device and, at the same time, put the plug into pairing mode.
    It does not matter which zone you place the plug in.

  3. Set the plug as a circulation pump
    Open the plug settings and set the device type to Circulation pump.

  4. Create a pump group
    Go to:

    Menu > Layout > Groups

    Create a new group and select Pump group as the group type.

  5. Link the pump to the pump group
    In the pump group, select the plug that switches the circulation pump.

  6. Link the correct devices to the pump group
    In the pump group, specify which rooms depend on the heat from this circulation pump.

    Select the device that determines the heat demand for the room:

    • if a room has a separate thermostat, such as Jip, Lisa, Anna or Emma, select that thermostat;

    • if a room only has a Tom and no separate thermostat, the Tom acts as the thermostat for that room. In that case, select the Tom.

  7. Do not automatically select all valves or actuators. Koen and Floor are valve controllers and do not independently determine the heat demand of a room. They therefore do not need to be linked separately to the pump group when the heat demand is already determined by a thermostat.

    The main rule is: link the device that determines the heat demand for the room to the pump group. This is usually the thermostat, or the Tom when there is no separate thermostat in that room.

Operation

With a pump group, Adam HA automatically switches the circulation pump on as soon as one of the linked rooms has a heat demand.

The pump remains on as long as there is still heat demand from at least one linked room. Only when all linked rooms no longer have heat demand will the circulation pump be switched off.

In addition, Adam HA automatically switches the circulation pump on for approximately 2 minutes every 24 hours if there has been no heat demand for 24 hours. This helps prevent the circulation pump from getting stuck due to long periods of inactivity.

Please note

If a room only has a thermostat installed, but no Plugwise radiator valve, make sure that the standard radiator valve or underfloor heating group in that room is open.

Otherwise, Adam can detect heat demand and switch on the circulation pump, but no hot water will flow through that room.
