Hour Meter
Total compressor cycle time is saved in EEPROM every six minutes of continuous
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 dis-
play 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
