3. ABB i-bus® KNX Weather Unit, WZ/S 1.3.1.2
Adjustable which Weathers Sensor is connected
Measured value represented in the appropriate type of data point, e.g. in m/s, in lux or in °C
2 threshold values for each input with upper and lower limit / threshold value can be modified via the bus
Logic AND / OR, 4 inputs, invertible
4 memories with 24 values each / storage takes place according to the FiFo principle (ring buffer)
Minimum duration of underflow and overrange adjustable (If the sending condition reverts during the minimum duration, no telegrams are sent)
Offset temperature +/- 5 °C
