MK2.2 De Dietrich-Steuerung 7778882

The MK2.2 control is an electronic control unit used in certain boiler models to manage heating and hot water functions. This component oversees operation, including ignition, temperature regulation, and safety monitoring. If your boiler is displaying error codes or failing to start, a faulty control board may be the cause. Replacing it with a compatible MK2.2 control can restore normal operation and improve system reliability. Ensure compatibility with your specific boiler model before installation.
