WAREMA climatronic®Sensor Interface
1 Characteristics
The WAREMA climatronic®Sensor Interface enables the integration of numer-
ous conventional sensors in a WAREMA climatronic®system where, due to
the structural situation, measurement data are required in greater number
and in high quality.
The Sensor Interface can be used as an alternative to the climatronic®
weather station or as an additional system component. The two prod-
ucts can be combined as required, although it must be noted that the
WAREMA climatronic®supports a maximum of three components for meas-
urement data collection.
The following meteorological sensors can be connected to the device:
4 "photo" sensors (inputs can be jointly switched from a voltage to a current
interface).
1 "solar radiation" sensor
1 "dawn/dusk" sensor
4 "wind speed" sensors
1 "wind direction" sensor
1 "temperature" sensor
1 "precipitation" sensor
1 "relative humidity" sensor
A DCF77 radio clock module can be connected as well.
A power supply for active sensors (15 V DC and 24 V DC) is integrated in
the device.
NOTICE Do not supply heating units in sensors with power via Sensor Interface. Use
a separate voltage source.
The Sensor Interface is connected to the WAREMA climabus, which also pro-
vides the necessary voltage.
The measurement values of the connected sensors are read in by the control
panel in blocks via the climabus:
Safety-related data such as the wind speed, wind direction, outside tempera-
ture, precipitation and relative humidity are read in once a second.
Photo, solar radiation, dawn/dusk and the DCF77 signal are read in once
every ten seconds.

urement of solar irradiation and temperature). Incident
radiation and temperature is converted into a propor-
tional output value.
In the angle of elevation and in the azimuth, the same
direction-dependent sensitivity is reached as with solar
panels. By using these neutral sensor elements, a cor-
relation with all solar collector technologies is possible.
The temperature output cannot be connected to the
Sensor Interface because the sensor only emits an ana-
logue signal.
Mounted, for example, using a fixing
bracket outside on the facade.
Additional mounting information can
be found in the sensor operating and
installation instructions.

"Dawn/dusk" sen-
sor
Art. no. 623082
The sensor is used to detect the light intensity of day-
light and corresponds to the sensitivity of the human
eye. The linearised electrical output signal enables, for
example, the brightness-dependent control of sun shad-
ing products.

Install the sensor using the mounting
bracket supplied, or, alternatively, on
a pole.
Attach the sensors outdoors at a
readily accessible but raised location
e.g. on the facade of a building to be
monitored.
For sun shading systems above
a facade side, the sensor must be
aligned so that the middle photo di-
ode is facing in the same direction
as the sun shading system.

Wind direction (1 input)
Wind direction
sensor
Art. no. 623048
The sensor is used to measure the wind direction. In
general, the wind meters should measure the wind con-
ditions over a broad area. To obtain comparable values
for the ground wind, measurements should be taken
at a height of 10 meters on level, undisturbed terrain.
Undisturbed terrain means that the distance between
the sensor and obstacles should be at least ten times
the height of the obstacle. If this requirement cannot
be met, the wind direction meter should be erected at
a height in which the measurement values are affected
as little as possible by the local obstacles (approx.
6 – 10m above the level of the disturbance). On flat
roofs, the wind direction meter should be erected in the
middle of the roof instead of at the edges to avoid pref-
erential directions.
The sensor is mounted on a stand
pipe. If a "wind" sensor is mounted as
well, the sensors should be mounted
in close proximity. Additional mount-
ing information can be found in the
sensor operating and installation
instructions.
No settings re-

Outside temperature (1 input)
Digital input; the temperature output of the temperature and humidity sensor cannot be connected.
Outside tempera-
ture sensor
Art. no. 628145
The sensor is used to measure the outside temperature
and is needed, among other things, for ice monitoring.
To deliver reliable measurements to
the sensor unit, the sensor should be
mounted, if possible, on the northern
side of a building and should not be
exposed to direct sunlight. Additional
mounting information can be found in
the sensor operating and installation
instructions.
No settings re-
quired
Precipitation (1 input)
Precipitation (ca-
pacitive) sensor
Art. no. 1002325
A switch signal is triggered by the precipitation sensor
in the event of precipitation in the form of drizzle, rain,
hail or snow. The switching threshold of the device is
factory-set to a typical value and can be adjusted by the
user after commissioning to the requirements of the sun
shading product and the local climatic conditions. When
the sensor surface is dry, the switch signal is cancelled
after an adjustable switch-off delay. The sensor surface
is heated, which prevents triggering in high air humidity
and ice formation in negative temperatures. After the
sensor surface has detected precipitation, it quickly
dries again because of the heating.
Mount the sensor using the enclosed
fixing material at an easily accessible
location near your sun shading sys-
tem. For best results, the orientation
of the sensor should be as northerly
as possible. Furthermore, the precipi-
tation must be able to hit the sensor
surface from any direction without
interference.

WAREMA climatronic®Sensor Interface
Sensor Function/connection Installation Setting
"Precipitation" sen-
sor (infrared)
Art. no. 623045
The sensor is used to measure precipitation in the
form of drizzle, rain, hail or snow. The precipitation is
detected via an IR light barrier system. A drop inter-
rupts the light barrier and triggers a signal in the down-
stream electronics. The precipitation causes a relay to
be switched whose floating contacts can be used to
inform the connected sensor unit of the precipitation.
For extreme weather conditions the device is equipped
with heating. The heating keeps the enclosure cover at
a temperature >0 °C to prevent the accumulation of ice
and snow. The power supply for the heating is provided
by a separate power supply unit.
The sensor is delivered with fixing
material and is suitable for wall and
stand pipe installation. Additional
mounting information can be found in
the sensor operating and installation
instructions.
No settings re-
quired
Relative humidity (1 input)
Temperature and
humidity sensor
Art. no. 623047
A capacitive humidity sensor converts the current hu-
midity value to an electrical signal.
The high quality metal housing and the weather and
radiation protected design guarantee a high level of
resistance to weather influences and very high precision
in data collection.
The temperature output cannot be connected to the
Sensor Interface since the sensor only outputs an ana-
logue signal.
The temperature and humidity sensor
must be mounted in a location that is
representative for climate measure-
ments. The sensor must be mounted
in such a manner as to avoid the pen-
etration of water into the sensor. Dew
and sprayed water do not damage
the sensor. In addition, the operating
voltages should be kept at the cor-
rect levels and the sensor should be
well ventilated. Deviations can lead
to measurement errors (e.g. due to
warming of the sensor). Additional
mounting information can be found in
the sensor operating and installation
instructions.
No settings re-
quired
Radio clock signal DCF77 (1 input)
"Wind/photo/radio
clock" sensor
Art. no. 623021
or
"Photo/radio clock"
sensor
Art. no. 623043
The radio clock receiver is used to receive the DCF77
time telegrams. To ensure that there is radio reception,
check the radio reception prior to the final installation
of the DCF77 module. Correct radio clock reception
can only be verified by evaluating the corresponding
network variables. Refer to the associated interface
description. If the time does not set itself within 5 min-
utes after commissioning, there is no radio reception.
Change the location of the receiver antenna and repeat
the commissioning procedure.
The LED on the Sensor Interface flashes at the rate of
the incoming time signals. However, up to 5 minutes
may pass until flashing starts. If the LED does not flash,
the DCF77 reception is strongly disturbed.
As in all radio receiver systems, the
radio clock receiver DCF77 can be
subject to certain reception limita-
tions and transmission disturbances.
If the product is installed outside of
the Central European time zone or in
areas with limited radio reception, the
DCF77 signal may not be received.
Note the information in the associated
operating and installation instructions.

4 Connection
4.1 Connection
information
WARNING
In a permanently routed installation, there must be an in-series
disconnecting and isolating device to separate the device from the supply
voltage (switch according to EN 60335-1, Section 25.2, e.g. circuit breaker).
A screw driver size 1 and 0 is needed to tighten the terminals. Electric screw
drivers may not be used.
230 V AC lines (power lines) should not be routed between the DIN rail and
rear wall but to one side at as great a distance as possible.
The external +15 V and +24 V voltages supplied by the device are intended
for sensors only.
Do not supply heating units in sensors with power via Sensor Interface.
Use a separate voltage source.
The capacitive precipitation sensor may be supplied via the Sensor Interface.
The specified lines are recommendations. The operator or installer is respon-
sible for compliance with the public utility provider regulations and the VDE
regulations according to VDE 0022.
The wiring specified in the cable diagrams is for minimum cross sections in
copper, taking no account of the length and the resulting voltage drops.
The relevant VDE regulations must be followed when routing lines outdoors.
Furthermore, the lines must be suitable for outdoor use.
High voltage and low voltage lines must be routed separately (at least 10 cm
apart).
If unexpected disturbances arise due to strong external EMC influences, un-
used inputs can experimentally be connected to earth.
DANGER
The electrical installation must be performed by a certified electrician in
accordance with the electrical installation regulations published by the
Association of German Electrical Engineers (VDE 0100) or the standards
and regulations of the country in which the device is being installed. The
electrician must observe the installation instructions included with the
supplied electrical devices.

4.2 Setting up the inputs
Depending on the sensor in use, it may be necessary to change the charac-
teristic of the inputs. This can be achieved using the encoding switches on
the printed circuit board. By default, all encoding switches are set to the OFF
position. For some sensors, the switches of the respective inputs must be
set to the ON position. The necessary settings can be found in Chapter 3.2
Mounting the sensor and in Table 5-1. This setting should always be made
with the device switched off.
