Switch-on delay
The EFOY COMFORT fuel cell does not start imme-
diately if the switch-on voltage only drops below
the set threshold level temporarily. The device
only starts automatically if the switch-on voltage
is still below this threshold level after the switch-
on delay. For example, with the factory default of
12.3 V for lead-acid batteries, the switch-on volt-
age must drop below 12.3 V for at least 60 seconds
in order for the EFOY COMFORT fuel cell to start.
If loads with a high rate of power consumption are
operated temporarily, this value must be set in ac-
cordance with the operating times of these loads.
You can find the permitted value range for the
switch-on delay in the table on page 90.
Switch-on voltage
The EFOY COMFORT fuel cell switches on at the set
voltage and charges the battery.
Setting too high a value for the switch-on voltage
results in frequent starting of the EFOY COMFORT
fuel cell. Setting too low a value for the switch-on
voltage results in damage to the battery. Past ex-
perience indicates that 12.3 V is a good value for
lead-acid batteries.
You can find the permitted value range for the
switch-on voltage in the table on page 90.
