Setting the clock and day of the week
1. Turn on the appliance at the ON/OFF key on the
display.
2. Press the ON/OFF and “M” Menu keys at the same
time to access the
TECHNICAL MENU
.
3. Use the
TOUCH PAD
to select the “
clock
” icon;
“
” starts to blink.
Press “
enter
” to confirm
.
Use the
TOUCH PAD
to set the current hour.
Press “
enter
”
to confirm.
Use the
TOUCH PAD
to set the current minutes.
4. The display will show:
VV
Voltage value
V1fan speed
Air flow rate
measured by
the pressure
transducer
target
Air flow rate
Air flow m3/h
Wait for the automatic calibration system to align the
value measured by the transducer to the target value.
5. Once fan V1 is calibrated, the system automatically
starts calibrating fan V2.
The display with show:
VV
Voltage value
V1 fan speed
Air flow rate
measured by
the pressure
transducer
target
Air flow rate
=
VV
Voltage value
V2 fan speed
Air flow rate
measured by
the pressure
transducer
target
Air flow rate
Air flow m3/h
Wait for the automatic calibration system to align the
value measured by the transducer to the target value.
Once fan V2 is calibrated,
the system automatically goes back to the main
screen of the technical menu (symbol “
V
” flashes).
NOTE:
with pressure transducer mounted, the MENU
“
PAr
” will show a parameter called “
Sprc
”; this param-
eter is the imbalance of the return flow rate compared
to the supply flow rate.
It can be altered with a range from +20 to -20 (%).
Example: if the parameter set is +10, the return is 10%
less than the supply flow rate.
WARNING:!: In case where one fan cannot be run at the
target flow rate, message "Out of Range" is temporarily
displayed.
Then, system steps to next extraction fan balancing or
ends the flow rates setting procedure.
When "Out of Range" is displayed, last flow rate blown
by fan just before the message is the one set by the sys-
tem, which is the flow rate as close as possible to target.
