8.1.3.11 Alarms
N
OTE
In case of “
UtL
” alarm (fault of the fan), in
addition to the display visualization, the
equipment emits an acoustic signal that
can be switched off pressing any key on
the user interface. The alarm is never
cancelled unless the equipment is
switched off or put in stand-by.
The heat pump working mode is automatically
disabled and the one with electric
resistance is activated in order to ensure
the continuity of the warm water supply.
PLEASE NOTE!
In case of “UtL” alarm, you must contact the
technical assistance.
