Installation Methods
Mount the Room Sensor T2A 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
Screw the cover frame (1 - not included in the scope of delivery, art. no.: 82001) to the mounting ring (2) diagonally at the top left
and bottom right using the two screws (2.2 x 4.5 mm) supplied. Align the Room Sensor T2A (3) to fit the mounting ring and push it
on.
Surface mounting
Use the surface-mounted frame set for surface mounting Art. No.: 82002.
For the connection of a Room Sensor T2A, 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.
Each Room Sensor T2A has a unique 16-digit 1-Wire ID. This ID is required for sensor-room assignment in °CALEON . 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
°CALEONbox instruction manual or in the °CALEONbox terminal plan sticker to simplify the later configuration of the system.
