The radiator thermostat Comet Plus is the successor, the new design variant, of its predecessor Sparmatic Comet. The digital thermostat has a high-quality metal nut that ensures a longer service life and an even better hold for the Comet Plus.The Comet Plus electronic radiator thermostat can be programmed individually. Four heating and four economy times can be set per day. The settings can be made directly on the Comet Plus or even more conveniently on the PC with the aid of the PROGmatic programming stick (not included, available as an accessory). Thanks to the window-open detection, Comet Plus recognises when a room is being aired and immediately closes the valve of the radiator thermostat to save energy. The valve is only opened again when the temperature rises or after an individually adjustable time.The various functions of the Comet Plus can save heating costs of up to 30%.
