Safety warnings
Attention:
Electrical equipment must be installed and fitted by qualified
electricians only and in strict observance of the relevant
accident prevention regulations.
Failure to observe any of the installation instructions may
result in fire and other hazards.
• The combination sensor can be directly connected to a weather station
(Best. Nr. 7541 40 03) which ensures further processing of the measured data and
transmission to the bus in the form of switching or value telegrams.
• The combination sensor Best. Nr. 7590 00 57 is equipped with a DCF77 receiver
which can receive the legal German time (CET or CEST) and transmit the signals to
the KNX/EIB bus (e.g. to synchronize KNX/EIB clocks).
• The internal heating of the combination sensor protects the electronic circuitry
against dew and condensation in the specified temperature range. It does not
protect against the formation of ice on the housing or on moving parts in extreme
weather conditions (freezing rain).
• For checking the function of the wind-wheel, the software of the weather station can
effect a plausibility check of the wind signal. If the software detects signals that do
not make sense, the system can move wind-sensitive fixtures (e.g. external blinds,
awnings) into a wind-protected position. Unlogical signals are transmitted, for
instance, when the wind-wheel is blocked due to icing.
• The combination sensor needs an external 24 V power supply, e.g. Best. Nr. 7591 00 01.
• The other functions of the device depend on the software of the weather station and
on the parameters programmed. Detailed information on this subject can be found in
the corresponding product documentation.

Combination sensor
Function
The combination sensor can measure wind speed,
precipitation, brightness and twilight. Brightness
can be measured separately for the cardinal points
East, South and West. Position and orientation of
the individual sensors see FIG. .
A: Wind-wheel
B1...B3: Brightness sensors West, East, South
C: Twilight sensor
D: Precipitation sensor
Combination sensor
Installation
Important: Combination sensor with DCF77
Check the place of installation for optimal reception of
the DCF77 time signal. Reflexions can cause reception
interference. Minimum distance from other electrical
devices: 3 m.
If no interference-free reception is possible, change the
place of installation by a few meters until the
combination sensor receives the time signal without
interference (see chapter „Antenna orientation").
• The device is fitted in its position of normal use
shown in FIG.
• For fitting on a tubular mast (∅ 35 ... 50 mm), the
sensor is supplied with a stainless-steel mounting
bracket. Fitting see FIG
North • The
unobstructed by obstacles in all directions.
• When the combination sensor is installed in front of a
wall, a minimum spacing of 0.5 m must be respected
to prevent incorrect measuring values due to
negative influence on the sensors.
• To enable the brightness sensors to clearly
determine the sun's actual position, the combination
sensor must be aligned with the help of a compass in
such a way that the precipitation window points to the
North (see FIG.
sensors are correctly aligned with the cardinal points
(FIG.
• To ensure perfect wind speed measurements, the
wind wheel must be able to turn freely. This can be
checked visually at low wind speeds.
• To obtain correct measurements, the housing should
be as free from dust deposits as possible. In
operation, the surfaces of the housing are cleaned
automatically by the falling rain.
