10-piece set of the fully automatic radiator thermostat Comet Plus. 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, ensuring longer durability 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. Settings can be made directly on the Comet Plus or, even more conveniently, using the PROGmatic programming stick (not included, available as an accessory) on a PC. Despite the programmed heating profile, the temperature can always be manually adjusted at the thermostat. Thanks to the open-window detection, 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 time. With the various functions of the Comet Plus, heating costs can be reduced by up to 30%.
