Viessmann Vicare thermostatic radiator head ref. ZK03840

The ViCare thermostatic radiator head is a servomotor for individual temperature regulation.

The ViCare thermostatic radiator head detects the current room temperature through an integrated temperature sensor. The ViCare thermostatic radiator head has an internal anti-freeze protection that prevents the pipes from freezing. If the ambient temperature drops below approximately 8°C, the ViCare thermostatic radiator head opens until the temperature reaches at least 8°C again.

With the “window opening detection” function, the thermostatic valve is automatically closed to save energy. To prevent the valve from getting stuck, the ViCare thermostatic radiator head motor is opened and closed every 7 days.

Data transmission:

In combination with the heat generator with Viessmann One Base or Vitoconnect, e.g. e.g. model OPTO2
