A faulty or broken display makes it impossible to monitor and adjust the system, which can lead to inefficient operation or undetected faults going unaddressed. This used original Vaillant complete display (part number 0020239939) has been carefully refurbished and tested and is fully functional, making it a cost-effective spare part that restores full visibility and control of your heat pump.
