With the HmIP Set Basic Heating XS, you can control your heating and air conditioning according to your individual needs, room by room, and monitor the room climate directly in the room, not at the radiator. The radiator thermostat is installed quickly and without tools, without interfering with the heating system or draining water, after removing the conventional radiator valve. It then ensures precise heating according to demand and your comfort temperature in every room. You can also save money – savings of up to 33% on heating costs are possible: pre-select room temperature based on usage habits, targeted reduction during absence (workdays, vacations), lowering temperature and saving heating energy while airing out (in cooperation with door/window contacts), during parties with many people in the house, etc. Demand-oriented heating through automatic and comfortable control of room temperature allows for heating cost savings of up to 33%. The radiator thermostat replaces conventional thermostats and ensures your personal comfort temperature in every room. Individual temperature profiles with up to 13 changes per day in an adjustable heating profile are possible. Ready to use with a pre-set heating profile.
