The temperature coefficient is negative, i.e. the resistance decreases as the temperature rises. The NTC characteristic is Temperature °C Resistance value k www.sauter-controls.com –20 96.97 –10 55.30 0 32.65 10 19.90 described below.

There is a 1 K error with a temperature difference of 5 K between wall and air at a dis-tance of approx. 1 m. Fitting These room temperature sensors can be fitted in various different ways. Single mounting (one unit) Fittin method Recessed mounting Wall mounting Wall mounted with surfacemounted power cable Recessed mounting with nonSauter frame Recessed junction box Suitable types, e.g.: D: Kaiser CH: AGRO F: Legrand If necessary No Suitable types, e.g.: D: Kaiser Double mounting (two units, one below the other) Fitting method Recessed junction box Recessed mounting Suitable types, e.g.: D: Kaiser CH: AGRO F: Legrand Wall mounting If necessary Wall mounted with surfaceNo mounted power cable Recessed mounting with Suitable types, e.g.: non-Sauter frame D: Kaiser Use of different frames Because the device insert is separate from the frame, there are many different possibilities for the type of mounting and choice of frames. This flexibility is achieved choosing the accessories accordingly. 0940240101 Frame, single, including mounting plate The mounting plate is screwed onto a recessed junction box. The device insert is placed onto the frame and connected to the mounting plate by pressing it in. 0940240201 Frame, double, including mounting plate Same as single frame. However, this enables two devices to be mounted one below the other or side by side. 0940240301 Base, single The base can be screwed directly onto the wall. In this case, the cable feed also comes out of the wall, from behind. The device insert is fitted onto the base by pressing it in.

Cable plate, double (packing unit: 10 pcs.) 0940240801 Mounting plate, double (packing unit: 10 pcs.) 0940240401 Base, double Same as single base. However, this enables two devices to be mounted one below the other or side by side. 0940240501 Cable plate, single/ 0940240601 Cable plate, double If the cable feed to the base is fitted on the surface, this accessory is fitted under the base. The cable plate can be broken open at various points in order to feed the cable in. 0940240701 Mounting plate, single/ 0940240801 Mounting plate, double If non-Sauter frames, e.g. frames made by manufacturers of light switches, are employed, then it is imperative that the mechanical function is correct. The mounting plate is screwed onto a recessed junction box. The device insert is placed onto the frame and connected to the mounting plate by pressing it in.
