Functioning of a wind direction-dependent control (according to DIN 18232-2)4.3
With no wind and wind speeds < 1 m/s, all NRA/RWA and air supply areas in the outer walls of the smoke section
are opened. At speeds > 1 m/s, only the supply air and NRA/RWA areas in the respective downwind wall surfaces
are opened. The wind speeds and wind directions are measured above the roof and averaged over a period of 10
± 2 minutes.
Operating requirements MBZ 300:4.4
In addition to the wind direction transmitter, connection and conguration requires wind sensor and, if necessary,
rain sensor:
Weather module WMà
Licensed software for conguring the MBZ 300à
See the central description for connection, and description of the software MBZ 300 for setting.
Assembly5
To mount the wind speed and rain sensor, see Installation Instructions „Wind and Rain Sensor Set GC 401 RS / GC
402 WVS“ (Mat. No. 143015)
For the connection to the RWA centre MBZ 300, see description of the centre; conguration of the wind direction-
dependent control for the MBZ 300 requires a licensed software of the manufacturer of the centre.
Installation of the wind direction transmitter5.1
The switching point for the wind speed sensor for the ventilation operation must be adapted to local conditions.
The smallest wind speed is set at the factory.
The sensors are mounted on the side of the building that faces the weather. Surrounding buildings andà
electrical equipment must not impair their function.
The console must ensure a secure hold even in extreme weather conditions (storm).à
Mount wind direction transmitter and wind speed sensor on one pole for perfect measurement results.à
The mounting position must be chosen in such a way that wind direction and wind speed can be ideallyà
determined (e.g. above the roof).
The north-marking of the wind direction transmitter must face exactly north.à
