Start-up
It is possible to operate the radio-controlled thermometer and the outdoor
sensor with rechargeable batteries. However, the operating time and the
display contrast, are reduced by the lower voltage (battery = 1.5 V, recharge-
able battery = 1.2 V). Since rechargeable batteries are very sensitive to cold,
the service life of the outdoor sensor is reduced further during the winter.
Thus, we recommend to operate both, the radio-controlled thermometer and
the outdoor sensor with high-quality alkaline batteries to ensure long and
reliable operation.
a) Inserting batteries into the radio-controlled thermometer
• Open the battery compartment on the back of the radio-controlled thermometer.
• Insert two AAA/Micro batteries into the radio-controlled thermometer paying at-
tention to the correct polarity (observe positive/+ and negative/-). Close the battery
compartment again.
• Once the batteries are inserted, the radio-controlled thermometer briefly shows all
display segments and some beeps are audible. If only unintelligible symbols appear
on the display, press the recessed "RESET" button (15), for example using a tooth-
pick.
• Then, the radio-controlled thermometer starts the search for the radio signal of the
outdoor sensor; the reception symbol (5) flashes. Do not press any button and do not
move the radio-controlled thermometer.
Insert the batteries in the outdoor sensor now; see next section.
b) Inserting batteries into the outdoor sensor
• Open the battery compartment on the back of the radio-controlled thermometer by
sliding off the battery compartment cover (21) downwards.
• Insert two batteries of type AAA/Micro into the outdoor sensor, paying attention to
the correct polarity (observe Plus/+ and Minus/-). Close the battery compartment
again.
• With each transmission step of the outdoor sensor, the red LED (17) on the front side
of the outdoor sensor flashes briefly.
• If the radio-controlled thermometer does not show any measurement value from
the outdoor sensor after 3 minutes, remove the batteries from the radio-controlled
thermometer and the outdoor sensor and repeat the steps described above.
Alternatively, you can start the sensor search manually, see the "Manual search for
the outdoor sensor" chapter.
c) Installation and assembly
• The outdoor sensor can be mounted on the wall through its rear opening (19) using a
nail, screw or hook. A small fold-out base (22) also allows the installation on a level
surface.
The outdoor sensor is suitable for use in protected outdoor areas. It should be
placed so that it is not exposed to direct sunlight, since this can result in a false
temperature reading. Precipitation falling on the outdoor sensor will also lead to a
false temperature reading, since this cools the housing.
Therefore, we recommend you choose the installation place carefully, so the out-
door sensor measures the correct temperature.
Never dip the outdoor sensor in or under water; this will destroy it!
• The radio-controlled thermometer can be mounted on the wall through its rear
opening (9) using a nail, screw or hook.
Using a fold-out stand (13), the radio-controlled thermometer can be placed on a
flat stable surface. Protect valuable furniture surfaces by using a suitable mat to
prevent scratches.
Manual search for outdoor sensors
• Press and hold the "SEARCH" button (11) for 3 seconds until a tone signal can be
heard. Then the display for the outdoor temperature (1) and the reception symbol
flash (5). The radio-controlled thermometer searches for the outdoor sensor for the
next 3 minutes.
• Do not press any button during the search process.
• In case of reception problems, reduce the distance between the outdoor sensor and
the radio-controlled thermometer or select a different installation location.
Switching between temperature units °C/°F
Briefly press the "F°C/°F" button (14) on the radio-controlled thermometer in order to
toggle between the units of temperature °C (degrees Celsius) and °F (degrees Fahr-
enheit).

Alarm function for outdoor temperature
The radio-controlled thermometer provides the option to emit an alarm signal if the
outdoor temperature falls below and/or exceeds a limit value.
a) Switching the alarm function on/off
Briefly press the "ALERT" button (16) several times to activate or disable the desired
alarm.

• No display:
b) Setting the limit values
• Press and hold the "ALERT" button (16) for 3 seconds until you hear a beep. Then
• Set the upper limit value using the "S" (10) button and/or "F°C/°F" (14) button (keep
• Press briefly the "ALERT" button (16); the symbol " " appears to indicate the lower
• Set the lower limit value using the "S" (10) button and/or "F°C/°F" (14) button (keep
• Briefly press the "ALERT" button (16) to exit the setting mode.
c) Stopping the alarm signal
• If the limit value is exceeded, the radio-controlled thermometer emits an alarm sig-
• The alarm can be terminated prematurely by pressing any button.
Display of the minimum/maximum values
The radio-controlled thermometer always displays the minimum and maximum values
of the last 24 hours; manual deletion is impossible.
Reset
The radio-controlled thermometer may be reset by pressing the "RESET" button (15).
The "RESET" button (20) is to be pressed on the outdoor sensor; this button may be
seen after the battery compartment cover is removed.
Range
The transmission range of the radio signals between outdoor sensor and radio-con-
trolled thermometer is up to 30 m under optimum conditions.
Due to the different influences on the radio transmission, no specific range can be
guaranteed. However, trouble-free operation is usually possible in a single family
house.
The range can be significantly reduced by proximity to cables, pipes, metal pieces,
electronic devices, and similar. Thick walls, steel construction, laminated insulated
glass windows, etc., also reduce the range very significantly.
If you notice that the radio-controlled thermometer does not contain any measured
values of the outdoor sensor, check the condition of the batteries in the outdoor sen-
sor first. Following that, select another location for the radio-controlled thermometer
and the outdoor sensor. If required, perform a manual search for the outdoor sensor
(see chapter "Manual search for the outdoor sensor").

nal. Besides, a corresponding symbol " " and/or " " flashes on the display.
The corresponding symbol will stop flashing only after the respective meas-
ured value is within the set limits again.
This transmission range data refers to the so-called "free-field range". How-
ever, this ideal arrangement (e.g., radio-controlled thermometer and outdoor
sensor on a plain even meadow without trees, houses, etc.) never exists in
practice.
