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.
Warnings:
• For all the models of the NEMO series and the Volo SR models: the "sun" and
"wind" intervention thresholds may be adjusted exclusively in the climate sensor.
Please refer to the sensor 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
material damages that occur due to atmospheric events not detected by the
sensors.
6.1 - Definitions and conventions
• Manual "Sun On" command = enables the reception, by the motor, of automat-
ic 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
overwrite the automatic operation of the automation.
• Manual "Sun Off" command = enables the reception, by the motor, of automat-
ic commands transmitted by the "Sun" sensor if present in the installation. When
the reception is disabled, the automation operates exclusively with the manual
commands sent by the user. The "Wind" and "Rain" sensors cannot be disabled
because they protect the automation from the action of wind and rain.
• "Over-threshold" intensity of sun/wind = a condition in which the atmospheric
phenomenon stands at values that are above the value set as threshold.
• "Under-threshold" Intensity of sun/wind = a condition in which the atmos-
pheric phenomenon stands at values ranging from zero to half of the value set as
threshold.
• "Wind protection" = a condition in which the system inhibits all the awning
opening commands because of the over threshold wind intensity.
• "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" = Raise, Lower or Stop command sent by the user by
means of a transmitter.
6.2 - Behaviour of the motor in the presence of
climate sensors
6.2.1 - Behaviour of the motor in the presence of "Sun" sensor (fig. 7)
When the intensity of the sunlight reaches the over-threshold, after 2 minutes from
the beginning of this condition the motor autonomously performs a lowering ma-
noeuvre. When the intensity of the sunlight reaches the under-threshold, after 15
minutes from the beginning of this condition the motor autonomously performs a
raise manoeuvre. Note – Momentary drops in solar intensity, lasting less than 15
minutes, are not detected. The manual commands of the user always remain active
and are added to those generated automatically by the system.
6.2.2 - Behaviour of the motor in the presence of "Rain" sensor (fig. 8)
The rain sensor recognised 2 states: "absence of rain" and "presence of rain".
When the motor receives the "presence of rain" information, it activates the com-
mand programmed in the same motor for this state (e.g., closing of the awning).
The rain sensor is deactivated after the absence of rain has been detected for at
least 15 minutes.
The manual commands of the user always remain active and are added to those
generated automatically by the system. Therefore, in case a manual command is
sent that is contrary to the previous automatic command, the system carries out
the manoeuvre and starts, in that same moment, 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 is automatically closed by the system.
4. After a few minutes (it continues raining...) the user commands
the opening of the awning.
5. After 15 minutes from the opening (it continues raining...) the
awning is closed automatically by the system.
6. It stops raining.
7. It does not rain for at least 15 minutes: the user commands the
awning to open again.
8. The awning stays open.
6.2.3 - Behaviour of the motor in the presence of "Wind" sensor (fig. 9)
When the intensity of the wind reaches the over-threshold, the system activates the
wind protection and automatically closes the awning. With the wind protection in-
serted the manual commands are deactivated and it is not possible to open the
awning. At the end of the barring period the manual commands are reactivated and
after 15 minutes the automatic operation is restored.
6.3 - Priority among atmospheric events and operat-
ing priority among the "Sun", "Rain" and "Wind"
sensors
The priority scale among the atmospheric events is as follows: 1) - wind, 2) - rain, 3)
- sun. Wind has a higher priority than the others. A phenomenon with a higher prior-
ity resets the phenomenon underway, if this has a lower priority.
Example:
1. On a sunny day, the intensity of the light is over-threshold; the sensor makes the
awning open automatically.
2. Rain hits the sensor; the system resets the existing sun condition and commands
the manoeuvre envisaged for the new rain condition.
3. The intensity of the wind increases and reaches the over-threshold; the motor
deactivates the automatic sequence set for the rain and commands a raise ma-
noeuvre (the awning will be locked by the system in the "0" closing position as
long as the intensity of the wind remains over-threshold).
4. The wind dies down and reaches the wind under-threshold; after about 10 min-
utes the wind alarm condition stops; at this point, if there is still the "raining" con-
dition, the rain sensor is reactivated and the preset manoeuvre is commanded.
5. When the sensor detects the "not raining" condition, it reactivates the "sun" sen-
sor and, if the light intensity is over-threshold, the system opens the awning.
6. When the light intensity drops to the under-threshold, after about 15 minutes a
raise manoeuvre is commanded.
6.4 - "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 at the time when the "Sun-On" command is sent the sunlight inten-
sity is over-threshold, the system commands the opening of the awning; instead, if
in that moment the sensor is already activated, the system is reset and activates the
sensor again, making the algorithms start again immediately.
If no manoeuvre is set when the "Sun-On" command is sent, the motor signals the
reception of the command by performing 2 movements. If at that time the sunlight
intensity is under-threshold and does not allow the awning to be opened, the mo-
tor will command the closure of the awning, in accordance with this condition. In the
conditions to perform a manoeuvre are not met (e.g. because the awning is closed
and it is not sunny), the motor will perform 2 movements to signal the reception of
the command, upon receiving the "Sun-On" command. By sending the "Sun-Off"
command, the automatic movement of the awning is inhibited in connection with
the sun phenomenon. Therefore the automation will only work in the manual mode.
Warning – The "wind" and "rain" sensors cannot be deactivated.
