Forced Absorption
In some cases it may be necessary to charge the battery at the absorption voltage for a
specific period of time. In the Forced Absorption mode, the Phoenix Multi Compact will
charge at the normal absorption voltage during the preset maximum absorption period.
The "absorption" LED will light up (only on Phoenix Multi Control).
The Phoenix Multi Compact can be switched to one of these modes from the remote control
as well as with the aid of the front switch. A prerequisite is that all switches (front, remote,
remote Control) are switched to "on", and that none are switched to the "charger only"
position.
Proceed is as follows to switch the Phoenix Multi Compact to either the equalizing mode or
Forced Absorption mode:
REMARK: switch quickly from "on" to "charger only" and back. The switch must be switched
in such a way that the intermediate position is, as it were, "skipped". If the relevant switch
remains in the "off" position for any length of time, you may run the risk that the appliance will
be switched off. In that case you will need to start again. Use a remote control for best
results.
1. Ensure that all switches (i.e., front switch, remote or remote control switch if
present are switched to the "on" position).
2. Ensure that the Phoenix Multi Compact is charging (an AC input voltage must be
present; check that the "charger" LED is one (only remote control: "mains", of
either the "bulk", "absorption" or "float" LEDs is illuminated).
3. Switch the switch successively to "charger only", "on" and "charger only". NOTE:
the switching itself should be done quickly but the interval between switching
should be from 1/2 to two seconds.
4. The "green front-led =bulk", "yellow front-led=absorption" and "red-front
led=float" LEDs will flash five times (only remote control the "bulk", "absorption" and
"float" LEDs will flash five times.

If the switch is not in the required position after these steps, it can be simply switched one
more time. This will not change the charging status.

Subsequently, the "green front led=bulk", "yellow front led=absorption"
and "red front led=float" LEDs will each light up for a period of two
seconds.
If the switch is switched to "on" while the "green front led=bulk" LED
illuminates, the charger switches to the equalizing mode.
If the switch is switched to "on" while the "yellow led=absorption" LED
illuminates, the charger switches to 'Forced Absorption'
