  • This actuator is only suitable when the existing actuator is fixed to the valve by two screws. It will not fit valves where the actuator pushes onto the valve.
    If it pushes on, then you will need to replace both valve and actuator.
  • The wiring is exactly the same.  If the SZM1801 fixes to the valve with two screws, then it will be a direct replacement.

  • Hi
    It is as follows.
    Switched Live from control - Brown
    Neutral - Blue
    Permanent Live - Grey
    Pump/Boiler - Orange


  • Yes, just make the two extra wires safe.

  • Hi.  It will fit to the existing valve so is a dry job.

  • Yes it will.  Depending on the age of the valve, you may need to use cable ties through the screw holes fix it in place.

  • Yes it will.  Wiring changes details are under the downloads tab.
  • That is not the part number.  Please email us a photo to sales@heatingcontrolsonline.co.uk.

  • Hi.  Yes it will.  You will need to isolate the two extra wires.

  • Yes, you can order for delivery to Cyprus.

  • Yes it will.
  • Yes that's correct. It is new.
  • It depends what device you are looking to plug it into. You can usually connect the plug from your old actuator to the new one by cutting it off at the wire and connecting the wires together.
  • They are bare wires
  • Yes it will.
