Installation and electrical connection

DANGER

Electric shock from touching live parts in the installation environment.

An electric shock can be fatal.

Before working on the device, disconnect the power and cover live parts in the area.

• Mount the room temperature controller on an internal wall opposite the heat source if possible.
• Do not mount the room temperature controller on outside walls.
• Avoid draughts from windows and doors.
• Ensure that the normal air circulation in the room reaches the controller without any obstacles.
• External heat sources influence the accuracy of the controller. Avoid direct sunlight and do not place heat-emitting devices in the vicinity of the room temperature controller (heaters, lamps, etc.).
• Dimmers also generate heat.
  If a controller is installed in a common switch frame with a dimmer, the distance between them should be as great as possible. When arranging them vertically, the controller must be installed underneath the dimmer.

5 Operation

Restricting the temperature setting range

The temperature controller is set ex works to the maximum setting range of 5 °C to 30 °C.

Fig. 6: Temperature setting range

Two adjustment rings are located in the setting knob. You can use these rings to restrict the temperature setting range required e.g. between 8 °C and 23 °C.

Procedure:

- Select the temperature limits.

Example: min 8 °C, max. 23 °C

- Important!

First position the setting knob roughly in the centre of the required setting range.

Example: The centre point between 8 °C and 23 °C is approximately 15 °C.

- Now remove the setting knob.

- Set the red locating ring to the max. temperature limit.

Example: 23 °C

- Rotate anti-clockwise.

The numbers on the outer dial apply!

- Insert the tip of a pen in the hole and turn the red ring to the left until it reaches 23^ (max. scale).

Scale for setting the temperature with dials

1 = approx. 5 °C
2 = approx. 10 °C
3 = approx. 15 °C
4 = approx. 20 °C
5 = approx. 25 °C
6 = approx. 30 °C
