Once you have completed the hookup, run the procedure 6.A to allocate the
"Open" or "Step-by-step" command to the key.
6.2 - Climate sensors for wind, sun, rain
The climate sensors of the NEMO and VOLO series let you move the awning auto-
matically, depending on weather conditions.
Wires to use to connect the sensors by wire:
White-orange + White-black (some models are connected exclusively via radio).
Up to five tubular motors can be connected to one accessory, respecting the polar-
ity of the signals (connect the white-black wires of all the motors to each other and
connect that white-orange wires of all motors to reach other).
Warnings:
• After connection (or after memorization) of a climate sensor, you must make your
procedure 6.A to select the command to associate with a single button ("Open"
or "step by step" command).
• For all the models of the NEMO series and the Volo SR and Volo ST models: the
"sun" and "wind" intervention thresholds may be adjusted exclusively in the climate
sensor. Please refer to the sensor instruction manual.
• For all the Volo and Volo S models: the "sun" and "wind" intervention thresholds
may be adjusted exclusively in the tubolar motor. Please refer to procedures 6.B
and 6.C in this instruction manual.
• The climate sensors must not be considered as devices to increase the safety of
the awning when it rains or there is strong wind. Nice declines all liability for any ma-
terial damages that occur due to atmospheric events not detected by the sensors.
• These climate sensors must not be considered as safety devices that can eliminate
failures in the awning caused by the effects of rain or strong winds; a mere electric-
ity blackout, in fact, would make the automatic movement of the awning impos-
sible. Consequently, these sensors must be considered as components of the
automated device, that are useful in protecting the awning. Nice declines all liability
for any material damages that occur due to atmospheric events not detected by
the sensors.
6.2.1 - Memorisation of a climate sensor connected via radio
To store a climate sensor to perform the procedure 5.11.
6.2.2 - Definitions and conventions
• Manual "Sun On" Command = enables the reception, by the motor, of auto-
matic commands transmitted by the "Sun" sensor if present in the installation.
When reception is enabled, the user can send manual commands at any time:
these override the automatic operation of the automated device.
• Manual "Sun Off" Command = enables the reception, by the motor, of auto-
matic commands transmitted by the "Sun" sensor, if present in the installation.
When the reception is disabled, the automated device operates exclusively with
the manual commands sent by the user. The "Wind" and "Rain" sensors cannot
be disabled because they protect the automated device from these atmospheric
phenomena.
• "Above-threshold" intensity of sun/wind = condition where the intensity of the
atmospheric phenomenon corresponds to high values above the set threshold.
• "Below-threshold" intensity of sun/wind = condition where the intensity of the
atmospheric phenomenon corresponds to low values below the set threshold.
• "Wind protection" = a condition in which the system inhibits all the awning open-
ing commands due to the intensity of the wind above the threshold.
• "Presence of rain" = a condition in which the system detects the presence of rain,
with respect to the previous condition of "absence of rain".
• "Manual command" = UP, DOWN or Stop command sent by the user by means
of a transmitter.
6.2.3 - Behaviour of the motor in the presence of climate
sensors
• Behaviour of the automated device when there is a
Sun sensor: fig. 7
When the intensity of the sunlight exceeds the set threshold for at least 2 minutes,
the motor automatically lowers the awning. When the intensity of the sunlight goes
below the specified delay threshold and remains there for at least 15 minutes, the
motor automatically raises the awning. N.B. – the delay threshold is about 50% of
the value for the specified sunlight threshold.
Momentary reductions in sunlight intensity, that last a short time or less than 15 min-
utes, do not affect the overall cycle. Manual commands sent by the user are in addi-
tion to the automatic commands.
The factory setting for the solar sensor setpoint is level 3 (= 15 Klux). If you wish to
change this value use procedure 6.B.
• Behaviour of the automated device when there is a
Rain sensor: fig. 8
The rain sensor recognises two states: "absence of rain" and "presence of rain".
When the motor receives the message "presence of rain", it automatically activates
the manoeuvre (Up or Down) that the installer has programmed for this condition(*).
The rain sensor is disabled automatically when it detects the absence of rain for at
least 15 minutes.
13 – English
(*) - If it starts to rain, the system automatically commands the awning to be raised
(factory setting). To change this setting, to perform the procedure 6.D.
The automatic rain function is deactivated after the absence of rain has been veri-
fied for at least 15 minutes. In this case, the manual commands are always active
and are in addition to the automatically-generated command. If a manual command
is sent that is contrary to the previous automatic command, the system carries out
the manual command and at the same time starts a 15 minute timer that regener-
ates the programmed automatic command once this time elapses (e.g. the closure
of the awning).
Example: 1) The awning is open. 2) It starts raining. 3) The awning closes. 4) The
user forces it to open after a few moments. 5) The awning opens again. 6) 15 minutes
after being opened, the awning closes again automatically. 7) It stops raining for at
least 15 minutes. 8) The user again opens the awning. 9) The awning remains open.
• Behaviour of the automated device when there is a Wind
sensor: fig. 9
When the intensity of the wind exceeds the set threshold, the system activates the
wind protection and automatically raises the awning. With the wind protection acti-
vated, the manual commands are deactivated and it is not possible to lower the awn-
ing. At the end of the barring period, the manual commands are reactivated and after
10 minutes, automatic operation is restored.
The factory setting for the wind sensor setpoint is level 3 (= wind at 15 Km/h). If you
wish to change this value use procedure 6.C.
6.2.4 - Priority among atmospheric events and operating prior-
ity among the "Sun", "Rain" and "Wind" sensors
Each condition has a priority level. The scale of priorities is the following:
1-wind, 2-rain, 3-sun.
Wind has the highest priority. A condition with a higher priority neutralises the one
with a lower priority.
Example: 1) On a beautiful sunny day the awning is lowered due to the effect of the
sunlight. 2) If some clouds arrive and a drop of rain falls on the sensor, the motor
neutralises the "sun present" condition and commands the specified manoeuvre for
the "rain present" condition. 3) If the speed of the wind increases and exceeds the
set threshold, the motor deactivates the specified automatic sequence for rain and
will send a command to raise the awning and locks it in the closed position for as
long as it is windy. 4) When the thunderstorm stops, the wind alarm condition elaps-
es after 10 minutes and, at this point, if the "rain presence" condition persists, the
setting for this is reactivated and the established manoeuvre is commanded again.
When the rain condition ceases, the routine for sun conditions are re-established. If
the sunlight intensity exceeds the threshold, the awning will re-open. When the sun-
light intensity falls below the threshold level for at least 15 minutes, a command will
be sent to raise the awning.
6.2.5 - "Sun-On" and "Sun-Off" commands sent by the user
The user may activate ("Sun-On") or deactivate ("Sun-Off" command) the reception
by the motor of automatic commands transmitted by the climate sensors present in
the installation. If the user sends the "Sun-On" command (automatic function ena-
bled) and at that moment it is sunny, the system commands the awning to open.
If the automatic device was already enabled, when another "Sun-On" command is
sent, the system is reset and the algorithms start again from scratch, with immedi-
ate effect. If a "Sun-On" command is sent but the level of sunlight does not allow the
awning to open (the sunlight threshold is not exceeded), the motor will generate a
command to close it according to the conditions at that time. If the conditions are not
such as to initiate a movement (e.g. the awning is closed and there is no sun), when
the "Sun-On" command is sent, the motor will remain still. If a "Sun Off" order is sent,
the automatic function is disabled.
Example: the awning is closed; a "Sun-On" command is sent; if it is sunny, the awn-
ing opens immediately without waiting 2 minutes.
By disabling the automatic function, the automatic movements associated with the
variations in sunlight intensity are blocked. Warning – The "Wind" and "Rain" sen-
sors cannot be deactivated.
