HIGH TEMPERATURE ALARM: e factory preset for this setting is “70”.
is setting designates the High temperature inside the cabinet at which the alarm is triggered.
We recommend leaving this setting at the factory preset.
LOW TEMPERATURE ALARM: e factory preset for this setting is 41.
is setting designates the Low temperature inside the cabinet at which the alarm is triggered.
We recommend leaving this setting at the factory preset.
ENERGY SAVINGS MODE DIFFERENTIAL: e factory preset for this setting is “4”.
is setting increases or decreases the Temperature Dierential for the Energy Savings Mode.
e recommended range for this setting is 2-4.
Standard Protection Mechanisms
e cooling unit is programmed to shut down certain components to protect those components, as well as the wine inside the cabi-
net, under the following circumstances:
Scenario
P1 Alarm
P3 > 140°F
What it means
Probe 1, which senses the
temperature inside the cabinet
and controls the on/o cycles of
the cooling unit, has failed
e condenser probe is
measuring temperatures
that are too hot
What happens
e cooling unit enters a timed
auto-cycle mode until Probe 1
is repaired or replaced. In this
mode, the cooling unit will turn
for 12 minutes and o for 8.
e compressor and condenser
fan will turn o until the
condenser temperature falls
below 140°F
Optional Protection Mechanisms
Magnum cooling systems are programmed to turn o the compressor and condenser fan in the event of an HA2
alarm, as described below.
Maintenance
e condenser coil at the back of the cabinet will collect dust, dirt and lint over time. It is critically important
to clean the lter periodically. If the lter become clogged, the cooling unit will not have proper airow and its
performance and longevity will be compromised.
For advanced cleaning, remove the lter and grill, and simply vacuum or brush the coils until all dust and lint
have been removed. Do not use compressed air to clean the coils because it may force dirt particles into the
cooling system and cause serious damage to its internal components.
