The Comet Plus radiator thermostat is the successor and new design variant of its predecessor, the Sparmatic Comet. This digital thermostat features a high-quality metal nut that ensures a longer lifespan and better grip for the Comet Plus. The electronic radiator thermostat Comet Plus is individually programmable. You can set four heating and four saving periods per day. The settings can be adjusted directly on the Comet Plus or even more conveniently using the PROGmatic programming stick on a PC. Despite the programmed heating profile, the temperature can be manually adjusted at any time on the thermostat. Thanks to the open-window detection, the Comet Plus recognizes when a room is being ventilated and immediately closes the valve of the radiator thermostat to save energy. The valve will only reopen when the temperature rises or after a user-defined period. With the various functions of the Comet Plus, heating costs can be reduced by up to 30%.
