Freedom Marine 20
When a Freedom or Link remote control panel
is connected to the unit, the switch on the unit
or on the remote may be used to turn the unit
ON/OFF. If the unit is turned ON using the front
panel switch and then turned OFF using a
Remote or Link, the unit will not be completely
OFF. If the unit will not be used for an extended
period of time, turn the unit completely OFF.
The unit is completely OFF when the LED dis-
play on the unit is OFF.
TSC (Temperature Sensitive Charging)
This provides for the connection of a
sensor to measure battery temperature for
compensated charging. If no sensor is
connected the charge voltage levels are set to
defaults based on battery type.
echo-charge
The echo-charge feature is incorporated
in the Freedom Marine Inverter/Charger to
enable multiple battery bank charging of the
start or auxiliary battery. Freedom 10, 15, 20
have one active echo-charge output.
Freedom 25, 30 have two active outputs.
The echo-charge automatically switches
On/Off, charging an auxiliary or start battery
without affecting the main house battery bank.
The maximum charge current is 15 amps at
14.4 volts.
The echo-charge is a voltage follower, fol-
lowing the three-stage charge modes of the
Freedom Marine Charger. The echo-charge
senses if the start battery needs charging and
diverts a portion of the charging current (up to
15 amps) to the start battery. This method pro-
tects the auxiliary battery from overcharging
echo-charge
NOTE: The charger will always follow the
house battery setting, even if you mix the type
of batteries in your house and start battery
bank. If the house battery bank is either GEL
or AGM and the start or auxiliary battery is wet/
flooded, the charger will follow the GEL or AGM
voltage setting.
The echo-charge will turn ON any time
the house battery is above 13 volts, regardless
of the charging source.
OPTIONAL REMOTES
If using one of the remotes, refer to the
installation instructions included with the
remote.
