This product should not be disposed of with household waste.
Please recycle the products where facilities
for electronic waste exist. Check with your local authorities for recycling advice.
Please note!
• The device may only be opened and installed according to
the circuit diagram on the device or these instructions by a
qualified electrician. The existing safety regulations must be
observed.
• Appropriate installation measures must be taken to achieve
the requirements of protection class II.
• This independently mountable electromechani-
cal or electronic device is designed for controlling the
temperature in dry and enclosed rooms only under normal
conditions.
• The device confirms to EN 60730, it works according opera-
ting principle 1C.
• The permissible relative humidity of max. 95% must not be
exceeded. Condensation is to be avoided.
• When starting up the room temperature controller, it
must be noted that the thermo-bimetal requires a certain
period of time to adapt itself to the room temperature. The
switching point will therefore deviate from the room tem-
perature immediately after installation or after switching off
the night set-back. The switching point accuracy is ensured
after approx. 1 to 2 hours of operation.
To heat up faster in the beginning and shorten the com-
pensation time in the beginning, we recommend setting
the room temperature higher than actually desired. After
attaining the temperature, the temperature setting can be
set back to the desired setpoint value.
Applications
• The room temperature controller controls the temperature
in closed rooms, such as apartments, schools, halls, work-
shops, etc. subject to normal ambient conditions.
Installation location
• Preferably opposite the heating source on an inside wall.

Room
Temperature Controller
• Installation height: approx. 1.5 m above the floor
• Avoid outside walls and air drafts originating from windows
and doors.
• Please observe that the normal convection air of the room
must be able to reach the controller without hindrance.
The controller should therefore not be installed between
shelves, behind curtains or be covered in any way.
• Heat from other sources has a negative influence on cont-
roller accuracy.
Therefore you should avoid:
direct sunlight, installation in the vicinity of TVs, radios,
heaters, lamps, chimneys, and heating ducts.
• Even a dimmer creates heat!
If the controller and a dimmer are installed in a shared
switch frame, the devices should be placed as far apart from
each other as possible. If the devices are installed above
each other, the controller must be below the dimmer on the
bottom.
Installation on 58mm flush-type box (DIN 49 073)
a) Remove casing cover:
- Pull off the adjustment knob
- Loosen the cover screw
- Pull off the cover
b) Electrical connection according to circuit diagram
(see below).
c) Mount the device onto the socket using the thread-forming
tapping screws for flush-type boxes.
d) Mount the casing cover with switch frame.
The cover must latch into the bottom part of the casing before
tightening the screw.
- Push the adjustment knob back on
To facilitate dismantling, the casing cover and switch frame
should be removed together.
Electrical connection
Connect all lines exactly as shown in the relevant circuit
diagram.
Please observe that the neutral conductor N is connected to
terminal N. If this is not the case, large temperature deviations
will result since the controller will not be able to function
properly.
Conductor cross-section: 1 mm2 to 2.5 mm

solid conductor
No protective-conductor terminal is required since the device
is completely insulated.

Narrowing down the temperature setting range
The controller is factory-set to a maximum setting range of
5 °C to 30 °C (see Fig. 1).
There are 2 ring gauges in the adjustment knob. These ring
gauges can be used to narrow down the temperature setting
range as required, for example to a range of 8 °C to 23 °C.
Setting procedure:
1. Select the temperature limits:
Example: max. 23°C min. 8°C
2. Note! First turn the adjustment knob to the approximate
average value in the middle of the desired setting range.
Example: The average value between 8°C and 23°C is
approx. 15°C
3. Then pull off the adjustment knob.
4. Set the red ring gauge to the max. temperature limit.
Example: 23°C
Rotate counter-clockwise. The numbers on the outside of the
scale are valid! Place the tip of a pen into the hole and rotate
the red ring counter-clockwise to 23°C (max. scale Fig. 2).
5. Set the blue ring gauge to the minimum temperature limit.
Example: 8°C
Rotate clockwise. The numbers on the inside of the scale are
valid! Place the tip of a pen into the hole and rotate the blue
ring to 8°C (min. scale Fig. 3).
6. Push the adjustment knob back on:
The indicator must be approximately in the center of the new
setting range; see 2.
Example: approx. 15°C
