Sunvic SP35/20 Heating Programmer / Central Heating Controller Clean cosmetic condition. Removed from storage and appears to have seen little or no use, however I have no way to test it so it is being sold as untested. Includes fixing screws as shown in photos. Model: SP35/20 Voltage: 240V 50Hz Backplate/base not included. Ideal as a replacement part for existing heating systems or for spares and repairs. Please inspect photos carefully as they form part of the description. Sold as seen.
