Automatic Mode; Switching On The Fuel Cell Manually - EFOY COMFORT 80 User Manual

Operation
3.4.1

Automatic mode

Automatic mode starts as soon as you connect the device to the vehicle's
power supply. The device monitors the battery voltage independently.
The fuel cell switches on automatically if the battery voltage drops below
12.3 V. The battery is then charged until the cut-off threshold of 14.2 V is
reached.
When the device is started, it goes through a start phase, which may last up
to 20 minutes. It only reaches its full rated output after this phase.
INFO:
If the device fails to start, check that the cover lid is not still attached to
the exhaust hose connector. Remove the cover lid.
INFO:
To ensure optimal battery maintenance, it is important that the charging
current is not abruptly stopped when the cut-off threshold is reached. For
this reason, the EFOY continues charging the battery for up to three hours
at a reduced current after the configured cut-off threshold is reached
(factory default = 14.2 volts). The length of the recharging period depends
on the battery voltage and power consumption.
INFO:
During normal operation, the EFOY fuel cell briefly interrupts power
generation several times each hour. A charging power of 0.0 A is
displayed when this occurs.
3.4.2

Switching on the fuel cell manually

You can switch on the device manually, regardless of the battery voltage.
After the start phase, the device is then in "charging mode".
INFO:
If the device fails to start, check that the cover lid is not still attached to
the exhaust hose connector. Remove the cover lid.
