Operating Instructions
Room temperature controller

1. Area of application

The room temperature controller is used to regulate the temperature in
closed rooms such as flats, schools, function suites, workshops, etc.

Safety instructions
Electrical equipment may only be installed and fitted by qualified

electricians while observing the current accident prevention
regulations. A relative air humidity of max. 95% may not be
exceeded. Avoid any moisture condensation. Non-observance of the
safety warnings or installation instructions may damage the device,
cause a fire or other hazards.

2. Installation

Notes:

• 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.

Mounting height: approx. 1.5 m above the floor.
Mounted in a switch box in accordance with DIN 49 073.

3. Connection

1. Carry out the electrical connection according to the respective wiring
diagram (Fig. (2) or Fig. (3).

Note:

Ensure that the neutral conductor N is connected to terminal N.
Considerable fluctuations in temperature may otherwise occur. Conductor
cross-section: 1 to 2.5 mm2 solid conductor.

Symbols used in the wiring diagram:

L = L conductor
N = N- conductor

= Connection for clock signal to reduce temperature

= Heating

= Cooling
RF = Resistor for thermal feedback
TA = Resistor for night reduction of room temperature

2. Clip the rocker (A in Fig.

c

) on the switch in the flush insert.

3. Place the center plate together with the frame on the flush insert. The
center plate must snap in place in the top left of the housing base.
