Product Details

This module is used for time restricted opening of the comfort ventilation function.
It is not always necessary for an electric actuator to open a ventilation unit (window or light dome) by its full stroke.
Sometimes, a small gap is sufficient for ventilation purposes.
This module enables time-controlled limitation of the actuator stroke.
The module has no influence on the actuator when an ”EMERGENCY OPEN” function is triggered. In this case the actuator opens to its maximum stroke.
