What it is

The Buderus 7746900069 is a replacement control unit for Buderus appliances. It is the control box that carries the electronic circuitry governing the appliance's operating sequence, including burner demand and safety monitoring. It is listed by Buderus under part type CONTROL BOXES and is supplied as a single unit for direct replacement of the original component.

Signs this part needs replacing

  • The appliance does not respond when a demand is made from the controls.
  • The display or indicator panel is blank, flickering or showing persistent fault codes.
  • The boiler runs erratically, cutting in and out without a change in demand.
  • Controls or buttons on the unit stop registering input.
  • The appliance fails to complete its start sequence after a reset.

Before you order

  • Confirm the appliance model and GC number against the compatibility table above before ordering.
  • If the existing unit carries one of the previous numbers 78199 or T0000781990, the 7746900069 is the current reference for that component.
  • Check the condition of any seals, gaskets or mounting fixings disturbed during removal and replace them if they are perished or damaged.
  • Isolate the electrical supply to the appliance before removing or refitting the control unit.
