conditioning unit is switched off via the relay on the
control connector.
If the voltage is restored to normal (after about 1
minute) the compressor is reactivated.
If even in this condition the alternator fails to meet all
energy requirements, the power supply of the inverter
is switched to the leisure battery. If the alternator
voltage returns back to optimal voltage, more or equal
to 13.2V, the power supply returns back to the starting
battery and the air conditioning compressor is
reactivated turning off the Economy function.
ENGINE OFF
SMART-
LINK allows you to use the inverter connected
to the leisure battery even when the engine is switched
off, without risk.
If, during use, the Leisure battery voltage drops below
the safety threshold (11.1V), SMART- LINK will go into
Economy mode: while keeping the air conditioning fan
running, it deactivates the air conditioning compressor,
reducing consumption and protecting the batteries
from deep discharges.
If the leisure battery voltage continues to drop,
reaching the critical threshold (10.5V), SMART- LINK
continues to reduce consumption by completely
isolating the inverter from the batteries.
The inverter will only become active again if the service
battery voltage reaches normal working values, or
when the vehicle alternator is switched on.
