Installation Methods flush-mounted switch box
Mount the HERZ clever&smart Room Sensor narrow It in a suitable place.
Caution!
Device and function may be damaged. Select a suitable environmental condition. Direct sunlight,
sources of heat and cold, e.g. radiators and windows must be avoided.

Mounting in flush-mounted switch box

Use the supplied screws (3.0 x 16 mm) to fix the mounting frame to the switch box. Open the terminals with a
screwdriver and make the electrical connection as described below.
Each HERZ clever&smart Room Sensor narrow It has a unique 16-digit 1-Wire ID. This ID is required for sensor-
room assignment in HERZ clever&smart Room Controller . The ID can be found inside the sensor on the type plate
and on the supplied sticker. We recommend placing the sticker in the table of the HERZ clever&smart Control Box
instruction manual or in the HERZ clever&smart Control Box terminal plan sticker to simplify the later configuration of
the system.
To connect a HERZ clever&smart Room Sensor narrow It one of the terminal points VDD/ GND/ DQ is required in
each case. The additional three clamping points are for easy connection of further sensors. Use a suitable twisted
pair cable and ensure sufficient wire cross-section e.g. LIYCY 2 x 2 x 0.75mm²
Only to be used with SELV or PELV protective extra-low voltage.
If shielded cables are used, contact between the shielding and the PCB can cause damage to the
device and lead to malfunctions.
