Hour Meter
Total compressor cycle time is saved in EEPROM every six minutes of con-
tinuous compressor running time. Cycles less than six minutes are discarded
to conserve memory and allow the most flexible hour-meter possible.
To view the hour meter proceed as follows:
➤ Turn off the AC power.
➤ Press the Down Button and hold it.
➤ Restore AC power.
✓ After Power-On Reset is complete, the following appears in the display:
– "Hr" is displayed for one second.
– The display blanks out for one second then displays the thousands of
hours for three seconds.
– The display blanks out for one second then displays the hundreds
units for three seconds.
✓ The unit returns to the last operating state before power was removed.
Maximum recorded time is 65,536 hours, the meter stops and can only be
reset by a service technician.
Service History Log
The Marine Climate System records and remembers the eight most recent
faults. Each time a fault is detected, a one hour timer is started.
Three consecutive faults within that hour cause system shut down, lock out
and display the fault code. During that hour, to conserve memory, the same
recurring fault is not recorded in the service history log. Continuous operation
for one hour without the same recurring fault clears that fault counter but the
event remains in the service history log until overwritten. Should a different
fault be detected during the hour, it will be entered into the service history log.
The following events are entered into the service history log:
 High Freon Pressure
 Low Freon Pressure
 Air Sensor Fault
