Four value memories which can store up to 24 values each are available. The Weather Unit
WZ/S 220.127.116.11 can be operated either with the new Weather Sensor WES/A 3.1 or with the former
sensor WES/A 2.1. The Weather Unit also provides the supply voltage for the connected
sensor. The Weather Unit has to be supplied with a operating voltage of 85 to 265 V AC.
The Weather Unit supports the ABB i-bus Tool for advanced diagnosis and improved commissioning.
The Weather Sensor WES/A 3.1 detects twilight, brightness in three directions, rain, temperature,
day/night, wind speed and the date and time using a GPS module. An additional heating
transformer is not required. The new Weather Sensor WES/A 3.1 can be connected to the new
Weather Unit WZ/S 18.104.22.168 or to the former Weather Unit WZ/S 1.1.
