1.0 Elite Controls • Introduction The Elite Control is designed for use with direct expansion air conditioning systems. The Elite is covered under existing Marine Air Systems Warranty Policy. Incorrect installation, neglect and system abuse are not covered under Marine Air Systems warranty policy. 1.01 Standard Features • User friendly five button display panel requires no manual for basic operation 1.03 System Overview Elite is a user friendly, easy to operate, programmable temperature control.
1.04 Normal Heating or Cooling Cycle Select Cool Mode and cooling only will be supplied. The cabin temperature will be maintained within 2°F (1.1°C) of the set point. Select Heat Mode and only heating will be supplied. The cabin temperature will be maintained within 2°F (1.1°C) of the set point. Select Automatic and both heating and cooling will be supplied as required. While in the Automatic Mode, Elite will maintain a 2°F (1.1°C) temperature variation. A 4°F (2.
2.0 Elite Controls • Basic Operation 2.01 Operator Controls and Display Panel 6-THREE DIGIT SEVEN SEGMENT DISPLAY The inside air temperature is displayed in the window whenever the control is turned on. 1-POWER BUTTON The Power Button is used to toggle between the On and Off Modes. Press the Power Button once to toggle the unit to the On Mode. The display also indicates program information, fault codes and outside air temperature when the optional outside air sensor is installed.
On Mode 12-MOISTURE MODE LED The Moisture Mode LED is lit when the Moisture Mode has been selected. This mode is used to control humidity during periods when the vessel is unoccupied. When the control is in the On Mode, power will be supplied to the appropriate control outputs and the display will indicate the current state of operation. The operating and program parameters resume based on those stored the last time the unit was operating. 2.
2.05 Fan Modes Entering Program Mode Automatic Fan Speeds The Program Mode can only be entered from the Off Mode. From the Off Mode and in the following order, press the Mode, Up, Down and the Mode buttons. These buttons have to be pressed and released in the order given. The numerals “85” which represent the high fan limit, appears in the display. The “85” is followed by the characters “P 1” followed again by the parameter setting “85”. “P 1” represents the first programmable parameter.

P-6: Low Voltage Monitor have the software identification number and the air conditioning unit serial number available. The serial number may be found on the dataplate label. The Elite has a built-in voltmeter circuit that monitors the AC input voltage. Depending on whether the input power supply is 115VAC or 230VAC, this parameter can be set to “OFF”, to “95” (for 115VAC input power) or to “195” (for 230VAC input power). The factory default setting is OFF. 2.
P-11: Cycle Pump With Compressor This de-icing feature is turned ON by default with programming parameter P-7 set to “1”. The behavior of the feature is always the same whenever an optional alternate air temperature sensor is installed . However, the feature has two different, selectable behavior modes when it is used in conjunction with the Elite display’s built-in room air temperature sensor. It attempts to compensate for any temperature discrepancy that the display sensor may experience.
P-19: Filter Cleaning/Replacement Timer Value & Reset have a 24K or an HV unit. A 24K unit is identifiable by the “24” in the model number (i.e., VCD24K). A High Velocity unit does not have a blower motor overhang, the motor is inside the blower, and there is an “HV” in the model number. If your air conditioner is one of these two models then you must change parameter P-14 to “SC” prior to operating the equipment.
Failsafe Level 0 Only “ASF” detected and displayed. The control will shut down and will not restart until the fault is repaired. Once repaired the control will restart after a two minute delay. Failsafe Level 1 All actions in level 0 plus all other faults detected but not indicated. The system shuts down for two minutes or until the fault is cleared whatever is longer. The system will restart if the fault is cleared. Failsafe Level 2 All actions same as level 0 and 1. Faults are indicated.
3.0 Elite Controls • Troubleshooting 3.01 General Troubleshooting 5. Seawater temperature too high for cooling or too low for heating. Also see specific digital or mechanical control troubleshooting sections following these general guidelines. Seawater temperature will directly affect air conditioning unit's efficiency. This air conditioning unit can effectively cool your boat in water temperature up to 90°F (32.2°C) and heat (if reverse cycle option is installed) in water as low as 40°F (4.4°C).
Fault: No heating. Fault: System runs continuously. Possible Reason/Correction Possible Reason/Correction 1. Unit is cool only, or if reverse cycle, reversing valve may be stuck. 1. Set point temperature is improperly set: too low for cooling or too high for heating. Tap reversing valve lightly with rubber mallet while unit is in Heat Mode. Call for service if that does not correct the problem. Raise or lower set point. 2. Porthole or hatches open. Close all port holes and hatches.
Fault: Fan is not running but the compressor is. Fault: System runs continuously. Possible Reason/Correction 1. Improper air sensor location. Possible Reason/Correction Verify display head location with criteria found in the control manual. Install alternate air sensor if necessary. 1. Failed triac on Passport I/O circuit board. Send for repair or call local service technician. Fault: Fan runs continuously although it is set to cycle with compressor. Fault: “HPF” is displayed.
Fault: “PLF” is displayed. Possible Reason/Correction 1. Indicates that seawater flow through the condenser coil is insufficient. Check for adequate seawater flow. Verify pump operation. Inspect the condenser coil, it may need cleaning (see Maintenance section). Sensor may be faulty, replaced if necessary. Call for service technician. Fault: “LAC” is displayed Possible Reason/Correction 1. Indicates the AC input voltage is less than 95VAC (for 115VAC input power) or 195VAC (for 230VAC input power).
4.0 Elite Controls • Maintenance Reversing Valves Return Air Filters Reverse cycle units have a reversing valve; the valve must be energized periodically to keep the internal parts moving freely. To do this, switch the a/c unit into heat for a few seconds once a month. Check the return air filter about once a month and clean as necessary. To clean the filter, remove it from the unit, rinse with water, air dry and reinstall.
5.0 Elite Controls • Manufacturers Limited Warranty Agreement The following warranty is extended to cover marine air conditioners manufactured or supplied by Dometic Environmental Corporation, and is subject to qualifications indicated. Dometic warrants for the periods set forth below that products manufactured or supplied by it will be free from defects in workmanship and material, provided such products are installed, operated, and maintained in accordance with Dometic’s written instruction.

Automated Factory Self Test Program Maximum recorded time is 65,536 hours, the meter stops and can only be reset by a service technician. 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 will continue until the AC power is interrupted or the Power Button is pressed once. Service History Log Elite will record and remember the last eight service problems or service faults detected.
If these conditions cannot be met, the Optional Remote Air Sensor must be purchased and installed in the return air stream. Display Panel Installation Before mounting the Elite or AH-Elite digital display panel touch pad, consider the location. The air sensor built into the display panel will provide excellent room air temperature sensing given a proper installation.
