Installation Methods Surface / flush-mounted
Wall Installation
Mount the HERZ clever&smart Room Sensor 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
Attach the mounting ring to the switch box with the arrow pointing upwards (2). Make the electrical connection as described below.
Attach insert
Hold the cover frame (1 - not included in the scope of delivery) against the mounting ring (2). Align the HERZ clever&smart Room
Sensor (3) to fit the mounting ring and push it on.
Surface mounting
Use the surface-mounted frame set 3 F810 52 for surface mounting.
Electrical Connection
For the connection of a HERZ clever&smart Room Sensor, one of the terminal points VDD/ DQ/ GND 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.
Type Plate and Sticker with 1-Wire ID
Each HERZ clever&smart Room Sensor 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
sticking 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.

HERZ clever&smart Room Sensor room assignment
There are two ways to assign a room to the HERZ clever&smart Room Sensor:
1. Using the unit ID via the HERZ clever&smart Room Controller menu 'Expert -> Settings -> Rooms -> Room X -> Temperature'.
2. As described under 1. via the HERZ clever&smart Room Controller menu in combination with the Touch-To-Assign function (T2A) on the HERZ clever&smart Room Sensor.

Connection examples
Example 1: Series connection. The installation leads from one sensor to the next.
The 1-Wire system must be realised with 3 wires (5 VDC, DQ, GND). The wiring must be done
in series, see diagram opposite. Stub lines should be avoided or made as short as possible.
The total cable length can be up to 100 m. A suitable twisted pair cable must be used and
sufficient conductor cross-section must be ensured, e.g. LIYCY 2 x 2 x 0.75 mm², in order to
avoid impermissible voltage drop at the HERZ clever&smart room sensors.
Example 2: Tree structure. Several stub lines lead from one main line to the individual sensors.
