Radiator thermostat – compact-2

Comfortable heating at the workplace with a particularly long battery operating time 

We spend a large part of the day at work. Your workplace should of course also have the optimum temperature so that you'll be comfortable there. Homematic IP provides the right indoor climate in your office too, at all times. You set the heating profiles in the app only. So no one forgets to turn off the radiator overnight - and you save valuable energy. And all this with a particularly long battery life of up to five years.

The Stiftung Warentest winner 2019 relaunched and even more long-lasting

Ideal for offices, doctors' surgeries, firms or kids' rooms: The closed housing design does not allow unwanted manual operation or tampering, and does not protrude into the room. Thanks to the long battery service life of 5 years, the radiator thermostat is also very low-maintenance.

You can set heating profiles via the Homematic IP app, a wall thermostat or by voice control. The dismantling protection included in the scope of delivery provides additional safety.

Dynamisch. adaptiver Abgleich

Homematic IP automates hydraulic balancing

Fraunhofer IEE confirms that the Homematic IP radiator thermostat automatically performs dynamic and adaptive balancing on the radiator.

more

Homematic IP thus eliminates the need for the expensive installation of presettable valves, which was previously necessary, and thus makes hydraulic balancing much easier.

offenes Fenster

Open window detection

If a window is opened in your home, the radiator automatically lowers the temperature to save energy.

more

Notice open windows and doors with the open window detection function or even more precisely with a window and door contact from Homematic IP.

The dynamic-adaptive balancing of Homematic IP

Studies by Fraunhofer IEE have confirmed that the Homematic IP radiator thermostats eTRV-2, eTRV-C, eTRV-C-2 and eTRV-Evo perform dynamic and adaptive balancing at the individual radiators.

This means that the manual hydraulic balancing of each individual radiator by means of a valve presetting is no longer necessary. Compared to conventional, static control, automatic balancing through Homematic IP also has the distinct advantage that the flow rate of each radiator is dynamically adjusted to the real heat demand of the respective room. This means that the heating is really always set efficiently - on any day and in any weather.
