GENERAL WARNINGS
IMPORTANT
• Important safety instructions: observe these in-
structions - improper installation can result in
serious injury.
• For personal safety it is important to observe
these instructions.
• Keep these instructions.
• All installation procedures, connections, pro-
gramming and maintenance of the product
must be performed exclusively by a qualified
technician!
• The sensor is not a safety device capable of elimi-
nating damage to the awning due to strong winds
(indeed, a simple power failure can prevent the
awning being automatically retracted). The sen-
sor is rather part of an automation capable of
protecting the awning and facilitating its use.
• The manufacturer is not responsible for damage due
to atmospheric events undetected by the device's
sensors.
• Do not open the device protection housing as it con-
tains non-serviceable electrical circuits.
• Never apply modifications to any part of the device.
Operations other than as specified can only cause
malfunctions. The manufacturer declines all liability
for damage caused by makeshift modifications to
the product.
• Never place the device near sources of heat and
never expose to naked flames. This may damage it
and cause malfunctions.
• The product is not intended for use by persons (in-
cluding children) with reduced physical, sensory or
mental capacities, nor by anyone with insufficient ex-
perience or familiarity.
• Make sure that children do not play with the product.
5 – English
• On the power line to the system, install a device for
disconnection from the power mains with a gap be-
tween contacts that assures complete disconnection
in the conditions of overvoltage category III.
• Make sure that the surface of the rain sensor is clean
and clear of leaves, snow and other objects: clean it
with a soft damp cloth, do not use alcohol, benzene,
solvents or other agents when cleaning it.
• Handle the product with care, making sure not to
crush, strike or drop it.
1 - PRODUCT DESCRIPTION AND INTEND-
ED USE
This product is a climatic sensor with integral radio
transmitter; its other components are indicated in the
Quick reference guide (Step 1 - fig. A). The sensor is
mains powered and is intended for use in automation
systems for awnings, shutters, skylights, etc. with Nice
tubular motors and control units. Any other use is to
be considered improper and is strictly prohibit-
ed! Nice declines all liability for damage resulting
from improper use of the product and other than
as specified in this manual.
Product operation is based on real-time readings of
variations in wind speed (not present on SRT), sunlight
intensity and the presence of rain or snow. When the
climatic sensor readings violate their thresholds (either
above or below), the sensor transmits a radio signal
to the motor's automation receiver, which in turn ac-
tivates an Up or Down manoeuvre, depending on the
type of signal received (above or below the threshold).
Up to 3 sensors can be installed on a single automa-
tion system, thus enabling data acquisition at different
points of the environment.
IMPORTANT – Nemo version "SRT" has an out-
put with a zero-voltage contact relay. The signal
for the presence of rain is given by closing the
relay contact.
2 - 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.
• The sensor may not be compatible with older mo-
tors manufactured before June 2004 or with TT0
control units.
• (fig. 1) In favourable conditions (unobstructed field),
the transmission range of the sensor is 100 m, how-
ever, since the sensor is intended to protect the
awning, it is advisable to install it at most 10-20 m
away from the motor. We also recommend check-
ing that the zone is clear of other wireless devices
transmitting on the same frequency, such as alarms,
wireless headsets, etc.: they can further reduce the
range or even block the transmissions of the device
to the motor.
• Make sure that the sensor's installation zone satisfies
the following requisites:
– (fig. 2) it must allow for full and direct sunlight ex-
posure of the sun sensor surface; never install the
product in zones subject to shade from awnings,
trees, balconies etc. or below a source of intense ar-
tificial light;
– (fig. 3) the area must ensure exposure of the wind
sensor blades (WSRT only) to the same ventilation as
that applied on the sun awning to be automated.
– (fig. 4) it must permit direct exposure of the rain
sensor to the rain.
• Since the sensor's body is jointed and can be orient-
ed as desired, ti can also be installed to sloping sur-
faces. The tilt range is given in the Quick reference
guide (Step 1 - phase 1).
• Ensure that the surfaces selected for installation are
solid and guarantee a stable fixture.
• Make sure that the sensor is protected against ac-
cidental impact.
