2.3. Mounting and connection
2.3.1. Layout of casing and pcb
2.3.2. Connection of the sensor
Remove the screwed on cover. Lead the KNX bus connection cable through the cable
entry on the bottom of the casing and connect the bus +/- to the terminal provided for
this purpose. Screw the cover back on.
2.4. Notes on mounting and commissioning
Do not open the temperature sensor if penetration of water (rain) is likely: Only a coup-
le of drops could damage the electronic.
Do not dip the measuring tip (metal sleeve with sensor) in water, as this will distort the
measuring results until the humidity sensor is completely dry again.
After the bus voltage has been applied, the device will enter an initialisation phase las-
ting 5 seconds. During this phase no information can be received via the bus.
