LIBERO LINE WOK INDUCTION
AUTOMATIC FAN SPEED:
This function automatically regulates the
“hood” fan speed according to operating conditions on the cooking
zones.
The appliance cannot see how much vapor/smoke we are producing when cooking but it can “see” the
temperature of the cooking surfaces… the algorithm works like this “hotter the surfaces= more steam = more
hood suction level”; colder the surfaces= less vapor = less need of hood suction”.
The Automatic Fan Speed algorithm is operative both in
ON and OFF state when Manual Fan Speed mode is
not active.
H2H button is not used for Automatic Fan Speed but just for Manual Fan Speed regulation.
Automatic fan speed signals are sent also during Cleaning or even if there is an POW error. Required speed
maybe wrong when the error involves a temperature sensor because temperature reading is unreal.
H2H ICON:
Regardless of whether Manual or Automatic Fan Speed mode is active, H2H icon indicated the required hood
fan speed as follow:
ON state: White when is required speed zero (hood fan off), red when is required hood fan speed differ-
ent from zero.
OFF state: Off when is required speed zero (hood fan off), red when is required hood fan speed different
from zero.
NOTE: During Cleaning the H2H icon is forced OFF. Despite of this, automatic fan speed regulation continues
according to cooking surface temperature.
