d) Placement of the connected heater/air conditioner
• Please comply with the operating instructions of the heater/air conditioner 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 operated far
away enough from the room thermostat, so as to ensure as little mutual interfer-
ence 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 version 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 programmed
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 thermostat.

Placement of the room thermostat
The temperature sensor is installed permanently in the room thermostat. For this reason, the
room thermostat measures the temperature of the location where it is operated (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 according
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 furniture 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 mini-
mally 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 temperature sen-
sor and it would consequently lead to switching on/off at a
temperature that greatly deviates from the installed tempera-
ture limit.
Selecting the temperature unit °C or °F
• Turn off the thermostat with the button "
• Press and hold both of the buttons „ " (7) and " " (8) at the same time for about 3 seconds
to switch between the temperature unit °C (Celsius degree) and °F (Fahrenheit 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 tem-
perature 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 tem-
perature 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 "
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 "
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 " " (7) or increased with the button " " (8) (hold the corresponding button longer for a
quick adjustment).
The installation is only possible when the room thermostat is switched on.
