Switch-off voltage 
If the battery voltage reaches the set level, the 
EFOY COMFORT fuel cell switches off, provided that 
the value set for the "Maintenance charge" param-
eter has also been reached. 
Please note your battery's end-of-charging voltage. 
Note the charging recommendations provided by 
the battery manufacturer. 
You can find the permitted value range for the 
switch-off voltage in the table on page 87. 
Switch-off current 
The EFOY COMFORT fuel cell switches off if the 
current drops below the set switch-off current 
after reaching the switch-off voltage. 
If you want the battery voltage to serve as the only 
switch-off parameter, set the maximum value, as 
the current is always below this value in EFOY 
COMFORT fuel cells. 
You can find the permitted value range for the 
maintenance charge in the table on page 87. 
Absorption time 
This function serves as an additional switch-off cri-
terion for EFOY COMFORT fuel cells if the switch-
off current is not reached within the set time peri-
od. 
You can find the permitted value range for the ab-
sorption time in the table on page 87.
