A number of designs can use wall-mounted temperature sensors. The module is always manufactured in the respective electrical design and it includes an internal temperature sensor and terminals for connecting an external temperature sensor (e.g. floor temperature).
The sensor consists of two parts. The internal part contains the sensor electronics and is terminated with 4 wires (the CIB and the external temperature sensor) and a connector, where the cable from the other part is inserted. The second part represents the wall-mounted design feature itself with an installed temperature sensor terminated on a 70mm cable with a connector. The second temperature sensor (NTC 12 k or NTC up to 100k) is e.g. for measuring the floor temperature.

Notes:
-
The external temperature sensor must be an NTC 12k or other NTC with the resistance of up to 100k; the connection cable can be up to dozens of meters long. A typical use is for a floor sensor, the recommended cables include e.g. the SYKFY or similar cables, with at least 1x2 wires with 0.5 mm diameter.
-
The module is designed as a small embedded module in a flush-box (KU68); it is terminated with four 10 cm wires (the CIB bus and an external temperature sensor) and a small connector, in which the temperature sensor cable from the top part of the module (the design cover with the temperature sensor) should be inserted.
-
The temperature sensor is usually placed in the front surface of the cover and is visible from the outside (a small oval metal housing), which guarantees that the sensor actually measures the temperature in the room, with the minimum effect of the heat dissipated by the internal electronics and the temperature of the wall.
