Installation site • Install the room temperature controller on an inte- rior wall and, if possible, directly across from the heat source. • Comply with the recommended installation height of approx.

(televisions, heaters, lamps, chimney, heating pipes etc.). • Dimmers also generate heat! If the room temperature controller is used in con- junction with a dimmer, the distance between the two should be as great as possible. If aligned verti- cally, the room temperature controller should be installed below the dimmer.

If the mounting and installation instructions are not complied with, a danger of fire and other dangers can arise. The room temperature controller is mounted in a 58-mm flush-mounted box in accordance with DIN 49 073. To install the room temperature controller, proceed as follows: 1.
Page 8
2. Electrical connection in accordance with wiring schematic (see Page 10). 3. Mount device into flush-mounted box with screws. Attention: Always mount support ring on wallpa- per. The support ring may not be wallpapered over when renovating. 4. Set housing cover with cover frame in place. Engage housing cover at the top left in the hous- ing basis and tighten screw.

Electrical connection. Connect all cables in accordance with the wiring schematic (see Page 10). If this is not done, great temperature fluctuations will result, as the room temperature controller cannot work properly. An earthed connection is not required, as the device is double insulated.

Setting the temperature limits Two setting rings are found in the setting knob. You can set the temperature limits as desired with them. The temperature controller is set to the maximum set- ting range of 5 °C to 30 °C at the factory.

3. To set the red setting ring to the upper temper- ature limit (23 °C here): Insert a pointy object (e.g. pen) into one of the holes of the red ring. Rotate the red ring anti- clockwise to 23 °C. The outer numbers of the scale apply here.

4. To set the blue setting ring to the lower temper- ature limit (8 °C here): Insert a pointy object (e.g. pen) into the hole of the blue ring. Rotate the blue ring clockwise to 8 °C. The inner numbers of the scale apply here.

Temperature adjustment When commissioning the room temperature control- ler, note that the thermo-bimetal requires a certain amount of time to adjust to the room temperature. This is why the switching point will deviate from the room temperature immediately after mounting or after night-time heating reduction switches off.

Temperature setting scale The scale for the temperature setting is found on the cover of the room temperature controller and is used for visual orientation when setting the temperature (from min. 5 °C to max. 30 °C). = approx. 5 °C 2 = approx.
