Rain sensor
The product can be purchased separately.
Connection
The rain sensor is connected to the control system by means of a 3-core
cable with a minimum cross-section of 0.5 mm
2
. This cable can be up to
100 m long.
Note:
If the rain sensor has been activated, it will take at least 2 minutes
before the comfort ventilation can be activated again.
The example below shows a cable connection with several control
systems but only one rain sensor.
