The ViCare thermostatic radiator valve is a radiator actuator for individual room control.

The ViCare thermostatic radiator valve records the current room temperature via an integral temperature sensor. The ViCare thermostatic radiator valve has an internal frost protection function that prevents the pipes from freezing. If the room temperature falls below approx. 8 °C, the ViCare thermostatic radiator valve opens until the temperature reaches at least 8 °C again.

With the "open window detection" function, the thermostatic valve is automatically closed to save energy costs.
To prevent the valve from sticking, the motor of the ViCare thermostatic radiator valve is opened and closed again every 7 days.

Data connections:

In conjunction with a heat generator with Viessmann One Base or Vitoconnect, e.g. type OPTO2.

Operation via app:

5 Stars. We are a family of 5, and we can't be happier with the hot water. After researching low-consumption hot water systems for nearly a month, we opted for the hot water heat pump. Delivery took only 3 days from the online order.

There was a one-day delay in delivery due to the package's height, but everything else was perfect.

Thank you :)
