Description
This control knob is fitted onto one of the spindles on the front of the appliance, allowing you to manually adjust various boiler functions. Depending on the model, it can be used to change the temperature or switch between operating modes. For example, some boilers allow you to select hot water without activating the central heating, or vice versa.
This part is compatible with three boilers in the Halstead range: the Halstead ACE HE, ACE HE, and CLUB HE 18.
Please check boiler manual for compatibility.
