  • I'm not sure what you mean by power off, as the voltage must be coming from somewhere.  If you mean no demand, then if the last demand was heating only, then the valve may output a lower voltage (50-150v) on the orange wire until there is another demand.  This is perfectly normal operation of the valve.  The pump or boiler should not be activated by this lower voltage.
  • If it stays in the H position when you switch the power off then it will be stuck and need replacing.

  • Hi,
    You will need to replace the valve body to fit the Drayton.  However, if it is stuck on heating only it may be because the valve body is stuck so needs replacing anyway.  Neither unit allows you to override into hot water only, as they have a spring to return them to this position.

    Make sure your existing valve is 22mm before ordering this one.

  • I'm afraid not.  I would recommending using HCO Code 11C13 to connect the old plug to the new actuator.

  • Yes it come with a 1m cable.
  • For CH only, both the white and grey wires should be 230v. For CH and HW, white only should be 230v. If that is what the valve is receiving, then it sounds like the valve has failed.
