2.3. Sensor assembly
1. First, place the windproof box with the supply connection. Seal the inlet tubes as
well, in order to prevent drafts.
5. Then screw the baseplate (circuit board) on to the box. The lettering OBEN/TOP
must be at the top and at the front.
6. Position the frame of the switch series and firmly put the sensor housing with the
latches onto the baseplate (circuit board) so that this is fixed to the frame.
2.4. Notes on mounting and commissioning
Never expose the device to water (e.g. rain) or dust. This can damage the electro-
nics. You must not exceed a relative humidity of 95%. Avoid condensation.
2.5. Establish wireless connection
1. Set the control system to teaching (follow the chapter
Teaching wireless connec-
tion
in the manual).
2. Press the programming button on the
WG AQS/TH-UP sensor
3. Observe the response from the control system ("device taught").
