Battery Monitor - Dometic ColdMachine 50 Instructions De Montage Et De Service

Technical description
The accumulator and TEC program control ensure a high cooling capacity
and improve the unit's efficiency. The accumulator is charged when there is
a sufficient supply of power (for example when powered by a mains adapter). In the
event of accumulator usage or under-voltage, the coolant is drawn from the
accumulator until it is empty. Thus, no power is taken from the battery during this
time.
The TEC program control always ensures that
• Cold energy is stored if there is excess electrical energy (external supply of power
by a generator).
• The coolant accumulator can be used at any time to ensure that the complete
battery power is used for other consumers.
• Stored cold energy is automatically retrieved to preserve the interior cooling
temperature of the cooling area, once the battery capacity is exhausted.

Further information on the coolant accumulator can be found in chapter
"Use coolant accumulator" on page 27.

Battery monitor

The cooling device is equipped with an electronic device to protect against revers-
ing the polarity when connecting to a battery. To protect the battery, the cooling
device switches off automatically if the voltage is insufficient (see following table).
