battery protection settings (see page 90). 
INFO: 
The EFOY COMFORT fuel cell switches off automatically. This fully-
automatic function is controlled by the two operating parameters of bat-
tery voltage and charging current. In order for the EFOY COMFORT to 
switch off, the voltage must drop below the set switch-off voltage level, 
and the current must drop below the set maintenance charge. The facto-
ry defaults for lead-acid batteries are a switch-off voltage of 14.2 V and a 
maintenance charge of 2.0 A (4.0 A for the EFOY COMFORT 210). This 
means that the EFOY COMFORT switches off as soon as the battery 
reaches a voltage of 14.2 V and the charging current drops below 2.0 A.
