Product Highlights in Detail

Group Extension for Large Buildings

For larger buildings, we offer the Option PKM 101 to add to ventilation groups. With the up to two ventilation groups of the WRS 101, up to four ventilation groups can be set up, ensuring compatibility with the predecessor model.

Additional Wind and Rain Sensor

Thanks to the additional wind and rain sensor that can be connected via the Option WRM 101, you can ensure that your windows and shading devices are automatically closed in bad weather.

This keeps indoor areas protected and you do not need to worry about storms or water ingress.

Module for Different Ventilation Modes


In addition, we offer the ventilation extension module for other peripherals such as thermostats or timers.

For example, you can ventilate automatically at a certain room temperature or at a preset time of day.

In addition to automatic mode, CLOSE mode and manual mode via ventilation buttons are also possible.

Separate Connections for Ventilation Buttons and Actuators

The WRS 101 has separate inputs for connecting ventilation buttons.

Wiring and cable routing are significantly simplified thanks to this innovation.
