GENERAL WARNINGS
Safety warnings
•
During device installation, always strictly
ob serve all instructions in this manual. If in
any doubt re garding installation, do not pro-
ceed and contact the Hunter Douglas Technical
Assistance for clarifications.
• CAUTION! – Important instructions: keep these
instructions in a safe place to ena ble future
product maintenance and disposal procedures.
•
CAUTION! – All installation, connection, pro-
gramming and maintenance operations must be
performed exclusively by a qualified technician!
• CAUTION! – The product is not to be considered
a sa fety device that eliminates faults on the
aw ning caused by strong winds (in fact a simple
power failure would make automatic retraction
of the awning impossible). The product should
be con si de red part of an automation used to
safeguard the awning and to facilitate use.
• Hunter Douglas declines all liability for material dam-
age cau sed by atmospheric agents not detected by
the device sensors.
• Do not open the device protection housing as it con-
tains electrical circuits that do not require mainte-
nance.
• Never apply modifications to any part of the de vice.
Operations other than as specified can only cause
malfunctions. The manufacturer de clines all liability
for da mage caused by makeshift modifications to
the product.
• Never place devices near to sources of heat and nev-
er expose to naked flames. This may damage the unit
and cause malfunctions.
Other warnings
• The device is powered by a photovoltaic cell which
must be exposed to sunlight. Therefore ensure that
the surface of this cell is kept clean and free of leaves,
snow or other elements: clean the surface with a soft
damp cloth, avoiding the use of substances contain-
ing alcohol, benzene, solvents or similar.
• The product packaging material must be disposed of
in full observance of current local legislation govern-
ing waste disposal.

PRODUCT DESCRIPTION AND INTENDED
USE
The climatic sensors are equipped with a built-in radio
transmitter encoding and independent solar power
supplied by a built-in photovoltaic cell; during the night
the sensor uses the residual power accumulated dur-
ing the day, thus eliminating the need for connection to
the mains power supply.
The product is designed for systems used to automate
sun awnings, shutters, skylights and similar, which
implement Hunter Douglas tubular motors.
Any other
use is to be considered improper and is strictly
prohibited! The manufacturer declines all liabil-
ity for damage resulting from improper use of
the product and other than as specified in this
manual.

UNIT OPERATION
Operation is based on the detection of variations in
wind speed or variations in the intensity of sunlight.
When the reading value exceeds the
trip threshold
(mo difiable parameter), the sensor transmits a “radio
signal” to the automation. This, in turn, activates the
set ma noeuvre according to the type of signal received.
•
“Sun” sensor (fig. 8)
When the intensity of sunlight, measured by the sensor
(
b - fig. 6
) exceeds the threshold, after 2 minutes the
sensor transmits the Descent command to the auto-
mation.
Otherwise, when the sunlight intensity falls below the
threshold value, after 15 minutes the sensor transmits
the retraction command to the automation.
•
“Wind” sensor (fig. 7)
When the wind speed, measured by the sensor (
a -
fig. 6
), exceeds the threshold, the sensor immediately
transmits the Up command to the automation and
blocks execution of any other command sent to the
automation, to protect the awning from the wind.
When the wind speed falls below the threshold value,
after 4 minutes the sensor unblocks the awning protec-
tion to enable other automation commands. After the
system is unblocked, if the sun threshold is exceeded,
after 15 minutes the sensor sends the command for
awning descent.
Note
- During normal operation of the product, the led
remains permanently off, even when the sensor sends
commands.

PRELIMINARY INSTALLATION CHECKS
AND PRODUCT APPLICATION LIMITS
• Read the technical specifications provided in the
chapter “
Product technical specifications
” to check
the application limits of the sensor.
•
(
fig. 1
) Ensure that the selected installation site for
the sensor is within the range with respect to the
automation to be controlled. Although the range in
favourable conditions (open field) can reach 100m,
as the sensor represents a protection for the awn-
ing, a maximum range of 10-20 m is recommended.
It is also recommended to check that there are no
other radio devices in the zone operating at the same
frequency, such as alarms, radio headphones etc.:
these may reduce the range further or even block
communication between the sensor and the automa-
tion.
• Ensure that the selected installation site for the sen-
sor meets the following requirements:
– (
fig. 2
) must enable direct sun exposure of the sun
sensor surface, at least at the time of day in which the
sun protection of the automation must be efficient;
never install the product in shaded areas caused by
awnings, trees, balconies etc.;
– (
fig. 3
) the area must ensure exposure of the wind
sensor blades to the same ventilation as that applied
on the sun awning to be automated.
• (
fig. 4
) Select the type of configuration for the the
sensor structure according to the angle of the sur-
face selected for installation.
Caution!
–
the wind
sensor blades must be positioned horizontally
