Automated Factory Self-Test Program Elite Control Operations Manual

18 L-2230 ENGLISH

• Use pressurized air injected at the seawater intake fitting to force system water through the seawater overboard

discharge fitting, thus expelling any trapped water from the system.

In addition, since the seawater pump utilizes a magnetically driven impeller, remove the impeller from the wet-end assembly,

wipe with an alcohol solution, and store in a warm, dry area until commissioning takes place.

AUTOMATED FACTORY SELF-TEST PROGRAM

The Elite software contains a self-test program to facilitate factory testing of the entire air conditioning system. Once the self-test

program is activated, the test cycle continues until the AC power is interrupted or the Power button is pressed once, which

returns the system to Off Mode.

To activate the self-test program, press the Power button immediately after turning on the AC power and while all LEDs are

illuminated (“888”). The control is now in the self-test program and “tSt” appears in the display.

Once activated, the self-test software continuously executes the following commands:

1. Turn on Heat Mode and supply heating for ten minutes.

2. Stop heating and run only the fan for five minutes.

3. Switch to Cool Mode and continue cooling for ten minutes.

4. Stop cooling and run only the fan for five minutes.

5. Return to step one and repeat procedure until interrupted.

To halt the self-test program, press the Power button once or interrupt the flow of AC power.

SERVICE UTILITIES

HOUR METER

The Hour Meter provides a way to judge a compressor’s longevity based on actual run time. Total compressor-cycle time is

saved in EEPROM every six minutes of continuous compressor running time. Cycle times of less than six minutes are discarded

to conserve memory and allow the most flexible Hour Meter possible.

To view the Hour Meter, disconnect AC power then reconnect it and immediately press the Down button while all LEDs are

illuminated (“888”). The following Hour Meter information appears in the display:

1. “Hr” displays for one second.

2. The display blanks out for one second then displays for three seconds a two-digit number representing thousands of

hours. (For example, a display of “02” equals 2,000 hours.)

3. The display blanks out for one second then displays for three seconds a three-digit number representing hundreds,

tens, and ones of hours. (For example, a display of “163” equals 163 hours. Combined with the example above, the

complete Hour Meter reading is 2,163 hours.)

4. The display returns to its last operating state before power was removed.

Maximum recordable time is 65,536 hours, at which point the meter stops and can only be reset by a service technician.

SERVICE HISTORY LOG

The control records and remembers the eight most recent faults. Each time a fault is detected, a one-hour timer starts. Three

consecutive faults within that hour cause system shut down, lockout, and the fault code displays.

The following events are entered into the service history log:

• High Refrigerant Pressure (HPF)

• Low Refrigerant Pressure (LPF)

• Air Sensor Failure (ASF)

• Low AC voltage (LAC).

• Pump or Loss of Seawater (PLF)

During the timed hour, to conserve memory, recurring faults of the same type are 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. If a different fault is detected during the hour, it is also entered into the service history log.

NOTE

Collect all discharged liquids and recycle or dispose of in a proper manner in accordance with federal, state and/or

local regulations.
