6.1.2.4 - Behaviour of the system with various weather conditions at
the same time
Each condition has a priority level. The scale of priorities is the following: wind, rain,
sun. Wind has the highest priority. A condition with higher priority neutralises one with
lower priority.
Example:
On a beautiful sunny day the awning is lowered due to the effect of the sunlight.
If some clouds arrive and a drop of rain falls on the sensor, the motor neutralises the "sun
present" condition and actuates the manoeuvre specified for "rain present".
If 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.
When the thunderstorm stops, the wind alarm condition elapses after 10 minutes and,
at this point, if the "rain present" 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 thresh-
old, the awning will re-open.
When the sunlight intensity falls below the threshold level for at least 15 minutes, a com-
mand will be sent to raise the awning.
6.1.2.5 - Sun-On and Sun-Off commands
The Sun-ON and Sun-OFF commands enable/disable automatic operation.
Sending a Sun-On command enables automatic operation, so that in strong sunlight the
awning is lowered automatically. If automatic operation is already enabled, the com-
mand resets the systems, and the detection/actuation algorithms start again with imme-
diate effect. When it receives a Sun-ON command, and no movement is required by
the algorithms, the motor will respond by moving twice. If a Sun-On command is sent
but the level of sunlight is not such as to open the awning (the sunlight threshold is not
exceeded), the motor will generate a command to close it according to the conditions
at that time. If no movement is required (for example, the awning is already closed and
the sunlight level is low), when it receives the Sun-On command the motor will move
twice to confirm reception. Sending a Sun-Off command disables automatic operation.
For example: awning closed ... press Sun-On, the awning immediately opens (if there
is sufficient sunlight), not 2 minutes later. If there is insufficient sunlight to open the awn-
ing, the motor moves twice...
Disabling automatic operation inhibits automatic operation by the sunlight algorithm.
The automatic functions associated with wind and rain cannot be deactivated.

WARNINGS FOR EVERYDAY USE OF
THE MECHANISM
7.1 • RDC function
This function reduces the force with which the mechanism closes at the top limit.
7.2 • Maximum continuous work cycle
In general, the tubular motors are designed for residential, and hence sporadic, use.
They guarantee a maximum continuous operating time of 4 minutes and in cases of
overheating (e.g. caused by continuous prolonged operation) a safety "thermal protec-
tion device" intervenes to cut the power supply, restoring it when the temperature returns
to normal.
7.3 • "Automatic limit switch update" function
Every time the awning collides with its top position, the limit switches adjusted by the
impact of the mechanical blocks (safety plugs and rigid anti-intrusion springs) are veri-
fied by the "Automatic limit switch update" to determine whether they have moved. This
allows the function to measure the new limit switch values and update the existing ones,
thereby recovering any slack due to wear and/or thermal shocks to which the parts of
the structure and the motor's springs are subjected.
The constant update of the heights allows the awning to always reach the limit switch
with maximum precision. This function is not activated when the stroke of the awning
lasts for less than 2.5 seconds and does not reach the limit switch.
7.4 • Commanding partial opening/closing of
the awning (height "H")
In general, to command the partial opening/closing of the awning, press the key as-
sociated with the partial height during programming (for more information, read point
06 of procedure 5.9). If the transmitter has only three keys and only one "H" height is
memorised, press keys s and t together to recall it.

WHAT TO DO IF...
(troubleshooting guide)
• When an Up command is sent, the motor does not start:
This can happen if the awning is near the Upper limit switch ("0"). In this case you
must lower the awning a little bit and give the Raise command again.
