Weather Unit (WZ/S 1.1) Application program Sensor Data 2.0 Adjustable which Weathers Sensor are connected. Measured value represented in the appropriate type of data point, e.g. in m/s, in lux or in C. 2 threshold value each input with upper and lower limit / threshold value modified via the bus. Logic AND / OR, 4 inputs, invertible. 4 memory with 24 values / storage each takes place in the FiFo principle (ring puffer). Minimum duration underflow and over range adjustable (If the send communication reverts during the minimum duration, no telegrams are sent). Offset temperature +/- 5 C. 2CDC 504 057 N0204 Seite 7

Functionality of the individual sensors GPS Radio receiver of basis from GPS. Connection to a satellite is sufficient, in order to date and time. World-wide applicable. 2CDC 504 057 N0204 Seite 16
Preparation of the Weather Sensors Cover with rain sensor Catches of the cover (left and right) Base The cover of the Weather Sensor is locked on the right and left side of the lower edge. Remove the cover from the Weather Sensor by pulling the catches carefully outwards. Be careful in order not to tear off the cable connection between the circuit board in the base and the rain sensor in the cover. 2CDC 504 057 N0204 Seite 17
Installation of the holder Bridge Bridge The weather sensor includes a combined wall/pole holder. When the unit supplied, the holder is fastened to the back of the housing with adhesive tape. 2CDC 504 057 N0204 Seite 18
Installation of the Weather Sensors Horizontal wall or pole The Weather Sensor is fastened horizontal and laterally with an assembly angle of 90. 2CDC 504 057 N0204 Seite 19
