with steel reinforcements or certain concrete compositions, steel
bearers, etc.), please reduce the distance between the external
sensor and the base station.
• If external temperatures fall below 0°C, the battery power of the
external sensor diminishes and the radio transmission signal be-
comes weaker. In this case please reduce the distance between
the external sensor and the base station.
• If the base station does not display the external temperature but
only „- - - -“, it may be because the batteries in the base station
are too weak, meaning it is unable to receive the signals from the
external sensor. Replace the batteries with new ones.
• Interruptions to reception can also be caused by other household
equipment, TV and radio remotes, interfering transmitters or
external transmitters, etc. In this case only „- - - -“, „HHH“ or
„LLL“ can be seen on the display. If this occurs, press and
hold the down arrow button for approx. 5 seconds to start the
sensor scanning process. Then wait a few moments. The current
external temperature should be displayed again after the external
sensor‘s next transmission signal.
• Weak batteries in the base station Replace the batteries as soon
as the low battery symbol is displayed. Wait for approximately
5 minutes before inserting the new batteries. Do not touch the
battery contacts when inserting the batteries. This will reduce
the corrosion behaviour of the contacts and extend the life of the
batteries. When inserting the new batteries always make sure
the polarity is correct. After changing the batteries proceed as
described under section 1.3 „Commissioning“.
• Weak batteries in the external sensor Replace the batteries as
soon as the low battery symbol is displayed. When inserting the
new batteries always make sure the polarity is correct. The exter-
nal sensor must then be registered again. To do this proceed as
described under section 1.3 „Commissioning“.
• Incorrect temperature and humidity display. The temperature and
humidity display are affected by direct sunlight and rain respec-
