motor speed to zero (stopping); in any case however, after approximately 1 minute, the hood resumes automatic
operation at the speed set by the sensor. Whenever the key is pressed during the display of filter alarms,
a RESET occurs, and the counting of the hours resumes again.  Key E : increases motor speed; in any case
however, after approximately 1 minute, the hood resumes automatic operation at the speed set by the sensor.
Modification of sensor sensitivity: sensor sensitivity can be modified by operating as follows:

- 

stop the hood by pressing key B. – Simultaneously press keys D and E (the sensor’s sensitivity index will

appear on the display)  - Pressing keys D or E, the sensor’s sensitivity will either increase or decrease (1
: minimum sensitivity / 9: maximum sensitivity). – whenever the power supply is interrupted, the sensor will
resume operation with a sensitivity index of 5.
Warning: in order to avoid damaging the sensor, never use silicone products near the hood!

OPERATION AS TRADITIONAL HOOD:

Key A : switches the lights on/off. Display C : - indicates the motor speed selected (from 1 to 4); - indicates
the operation of the Timer when the number is flashing; - indicates filter alarms whenever the central segment
is illuminated or flashing. Key D : decreases motor speed  / Stop / Reset;  decreases motor speed to zero
(stopping). Whenever the key is pressing during filter alarm display, a RESET occurs, and the counting of the
hours resumes again.  Key E : enables the motor /  increases motor speed /TIMER. Pressing this key starts
the motor (at the latest speed set); pressing the key again increases motor speed, while keeping the key pressed
down for a few seconds enables the TIMER, and 5 minutes later the motor will stop (while the number of speed
setting selected will simultaneously begin flashing on the display); the Timer will remain enabled if motor speed
is changed. In order to disable the Timer, press the key again.

Controls in Fig. 18:

Button A: Turns the lights on/off. If held down for about 2" when the filter alarm is active, it resets the hour counter.
Button B: Activates/deactivates the “Automatic” function. Light S – Filter alarm: When the light comes on, it indicates
that 30 h of use have elapsed; it remains on for 30". When the light S flashes, it means that about 120 h of operation
have elapsed. The filter reset is indicated only when the motor is off, both in manual and automatic mode.
Automatic operation with sensor:
When the button B is pressed, the automatic function is activated. This is indicated by the corresponding LED coming
on. When the LED B flashes, it means that the sensor is waiting for data.
Modifying sensor sensitivity:
While in manual mode and with the motor off, simultaneously press the buttons B and C. At this point, the set
sensitivity is indicated by the LED C, D or E coming on. To set the desired sensitivity press one of the buttons C, D
or E  (min, med, max). Press B again to store it.
Press button B once again to go to manual mode.
Operation as traditional hood:
If in automatic mode, press the button B to change to manual mode; the LED B goes off.
Press one of the buttons C, D or E to start the motor in 1st, 2nd or 3rd speed, respectively. Hold the same button
down for 2" to turn off the motor.

Controls in Fig. 19:

A) Turns the lights off.
B) Turns the lights on.
C) Reduces the motor speed until reaching zero. If pressed for 2" when the Filter Alarm is active, the HOUR counter is
reset.
D) Drives the motor (calling the last speed used) and increases the speed until reaching maximum.
E) Activates/deactivates the sensor (AUTOMATIC or MANUAL mode). In Automatic mode the sensor is active and the
letter “A” appears on the display (L).
L) Display:
- signals the running speed
- signals Automatic mode by displaying the letter “A”. When the motor speed is changed, the running speed is displayed
flashing 3 times, and then the letter “A” reappears.
- signals the filter alarm (with motor off) by displaying the central segment for 30".
FILTER ALARM: Displayed for 30" when the motor is off:
After 30h of operation the central segment lights up on the display; It indicates that the grease filters need to be cleaned.
After 120h of operation, the central segment flashes on the display; It indicates that the grease filters need to be cleaned
and the charcoal filters replaced.
After cleaning the grease filters (and/or replacing the charcoal filters), restart the hour counter (RESET) by pressing the
key C during display of the filter alarm.
GAS SENSOR SENSITIVITY: The sensitivity of the sensor can be modified to suit your requirements. To modify the
sensitivity, the appliance must be in manual mode (i.e. the running speed and not the letter “A” must appear on the display);
If not, press the key E.
Modify the sensitivity by simultaneously pressing the keys D and E. The set sensitivity is indicated on the display. By
means of the buttons C(-) and D(+) the desired sensitivity is set Store the “new” sensitivity by pressing the key E.
