CDA Matrix MHN101FR User Manual page 10

Please note: The booster function cannot be used on two vertically
arranged cooking zones at the same time. This is to prevent damage
to the internal modules caused by overheating.
If the appliance's electronic circuits or induction coils overheat
whilst the booster function is in operation then the function will be
automatically deactivated and the zone will continue to operate at
its nominal power. The booster function will be available again once
the internal components have been cooled sufficiently.
It is normal for a high pitched whirring noise to begin whilst the
booster function is in use. This is the cooling fan inside the hob
keeping the internal components as cool as possible.
If a pot is removed from the cooking zone whilst the booster function
is in use, the function remains active and the ten minute countdown
continues.
Operating time limiter
In addition to the booster deactivation timer, each zone has an
operating time limiter to increase overall efficiency and to prevent
the hob from being left on indefinitely. If a zone's heat setting is
not changed for a specific duration then the associated zone is
automatically switched off and residual heat indicator activated.
Zones can still be used as normal in accordance with the operating
instructions. The operating time limiter is set according to the last
selected heat setting. The maximum operating times for each setting
can be found on page 11.
