The purpose of the wind/rain sensor, including the electronics, is to send a command to the control panel for NSHEV, or for ventilation only, to close the skylight in the event of increased wind (adjustable wind speed) or rain.
The electronics contain 4 separate switching contacts (allows for independent ventilation lines)
The wind and rain sensor is connected to the electronics. This system enables the adjustment of:
Wind sensitivity,
Heating the rain sensor,
Service mode (line blockade)
