d) Placement of the connected heater/air conditioner
• Please comply with the operating instructions of the heater/air condition-
er that you connect to the room thermostat.
• For safety reasons, many heaters/air conditioners must not be operated
without supervision.
• In any case, keep a sufficient distance between the heater/air conditioner
and flammable items (e.g. curtains).
• Place a portable heater/air conditioner only on a stable, flat, level surface.
• Never cover the heater/air conditioner.
• Keep the heaters/air conditioners out of the reach of children! There is not
only the risk of injury or burns but also the risk fatal electric shock!
• Do not connect multiple heaters/air conditioners to the room thermostat.
• Make sure that the connected heater or cooling device is set up and oper-
ated far away enough from the room thermostat, so as to ensure as little
mutual interference as possible. Otherwise, switching processes occur
unnecessarily often.
Preparation
Warning on the serial plate is in German. The scope of supply contains an additional
sticker with warning in English and Dutch. Put the sticker with suitable language ver-
sion onto the room thermostat.
Initial start-up, recharging the integrated accumulator
The room thermostat features a built-in NiMH battery. The battery serves to prevent
data loss in the event of a power failure (back-up time up to 200 h).
Furthermore, the room thermostat (with fully charged battery) can be pro-
grammed even if it is not connected to a mains socket.
The battery is fully charged if the room thermostat has been connected to
the mains voltage for approx. 8 - 12 hours.
At delivery, the NiMH battery is usually empty. Nothing is shown in the display. In order
to perform the programming in this case, connect the room thermostat to a mains
socket. Shortly after, the display will be activated and you can start up the room ther-
mostat.

Placement of the room thermostat
The temperature sensor is installed permanently in the room thermostat. For this rea-
son, the room thermostat measures the temperature of the location where it is oper-
ated (e.g. when it is plugged to a wall outlet).
In a closed room, the cool air sinks and warm air rises.
For this reason, it may be necessary that the temperature limit is chosen ac-
cording to when the room thermostat should switch on a heater or a cooling
device.
Also make sure that the connected heater or cooling device is set up and
operated far away enough from the room thermostat, so that the mutual
interference is as little as possible. Otherwise, switching processes occur
unnecessarily often.
Consequently, the room thermostat should never be operated close to furni-
ture or covers because they prevent the air circulation in the room.
Connect the room thermostat in the mains outlet (wall-socket),
so that the display is on top and the front outlet is below. In this
position, the temperature sensor is located at the bottom of the
room thermostat (see the circle mark on the picture on the right),
whereby it is not or only minimally affected by the heating from
the room thermostat itself.
With another operating position, the heating-up of the
room thermostat would have greatly affected the tem-
perature sensor and it would consequently lead to swit-
ching on/off at a temperature that greatly deviates from
the installed temperature limit.
Selecting the temperature unit °C or °F
• Turn off the thermostat with the button “ “ (9) so that the control-LED (1) goes off.
• Press and hold both of the buttons „
F
“ (7) and “
S
“ (8) at the same time for about
3 seconds to switch between the temperature unit °C (Celsius degree) and °F (Fah-
renheit degree).
Choosing the operating mode
The room thermostat has two operating modes:
1. Heating mode
In this operating mode, the room thermostat turns on the connected device when the
room temperature sinks below the installed temperature limit. This operating mode is
therefore suitable for connecting to a heater.
2. Cooling mode
In this operating mode, the room thermostat turns on the connected device when the
room temperature goes above the installed temperature limit. This operating mode is
therefore suitable for connecting to a cooling device.
To switch between operating modes, proceed as follows:
• Turn off the thermostat with the button “ “ (9) so that the control-LED (1) goes off.
The operating mode currently installed in the room thermostat appears at the top of
the screen (“ “ = Heating mode, “
“ = Cooling mode).
• Press and hold both of the buttons “ “ (9) and “
S
“ (8) at the same time for 3 sec-
onds to switch between operating modes.
Installing temperature limit
The temperature limit shown at the lower right corner of the display can be reduced
with the button “
F
“ (7) or increased with the button “
S
“ (8) (hold the corresponding
button longer for a quick adjustment).
The installation is only possible when the room thermostat is switched on.
