Operation Elite Control
7.1 Understanding the Heating and Cooling Cycles
The heating and cooling cycles operate differently
depending on the system installed. This section
describes the possible cycles.
7.1.1 Normal Heating or Cooling Cycle
In AUTOMATIC mode, heating and cooling are supplied
as required to meet the cabin temperature set point.
• The system starts a cooling cycle once the cabin
temperature exceeds the temperature set point by
2°F (1°C) and starts a heating cycle once the cabin
temperature falls below the temperature set point by
2°F (1°C). The system continues the cycle until the
cabin temperature equals the set point.
• During a cycle, the cabin temperature must drop
below the set point by at least 4°F (2°C) before the
system switches from cooling to heating or exceed
the set point by at least 4°F (2°C) before the system
switches from heating to cooling. This behavior
prevents small temperature overshoots from causing
the system to switch between heating and cooling
when it is not necessary.
COOL mode supplies cooling only and HEAT mode
supplies heating only.
• The cabin temperature for either mode is maintained
within 2°F (1°C) of the set point by default.
• When the heating or cooling set point is satisfied,
the compressor cycles OFF and the fan returns to low
speed.
To view the current water temperature, press and hold
Power and Down. Refer to “Using the Control Display
Panel” on page 13. The fan remains on low speed
until the adequate water temperature is available.
To provide heat when the required water
I
temperature is not available, install the optional
auxiliary electric heater and program parameter
P-13. Refer to “Programming the Control” on page
14.
7.1.3 Air and Water Temperature
Differential (CW Systems Only)
The electric heater and the chilled-water heat can affect
the CW system.
The optional auxiliary electric heater overlaps with the
chilled-water heat by 22 °F (12° C). The heater turns on
when required and remains on until the chilled-water
temperature exceeds the ambient air temperature by
22 °F (12° C) or until the room temperature is satisfied.
During very cold conditions, the auxiliary electric heat
overlaps the chilled-water heat to supplement heating.

7.1.2 Chilled-Water System Operation
(CW Systems Only)
In CW systems, the water valve does not open unless the
water temperature is adequate to heat or cool the cabin.
The adequate heating or cooling water temperature is
defined by the water temperature differential setting in
the control parameters. Refer to “Selecting a Parameter”
on page 16.

Elite Control Operation
7.1.4 Reversing-Valve Operation (DX
Systems Only)
COOL mode or HEAT mode is determined by the
position of the reversing valve. The reversing valve is
programmed to automatically toggle in these situations:
• When the system is running and an opposite cycle is
needed to maintain the temperature, the reversing
valve will toggle to the opposite position to initiate
the opposite cycle and reduce the starting surge of
the compressor.
• When a cooling or heating cycle is initiated aer the
system has been OFF for less than five minutes.
• When a cycle is interrupted by changing the display
mode to OFF or changing the set point from the
display panel.
To reduce reversing-valve noise, unnecessary valve
toggling is limited by default. Program the minimum
compressor staging delay (parameter P-3) to five
minutes or greater, to eliminate valve toggling. Refer to
“Programming the Control” on page 14.
When the system is powered up, a power-on-reset
I
always initiates a valve toggle.
and by periodic HEAT mode cycles with the fan turned off.
The de-icing cycle algorithm initiates periodic
compressor shutdowns every 10 minutes if the inside
temperature is at or below 69 °F (20 °C). The lower the
temperature, the longer the compressor shutdown will
last. In addition, the de-icing cycle algorithm will perform
brief reverse cycle runs (with the fan purposely turned
off) if the cooling cycle runs for 40 minutes without any
cooling progress or if the cooling cycle runs for more
than 60 minutes, regardless of cooling progress.
The parameter setting for the de-icing feature
depends on whether you are using the
optional inside air temperature sensor or the
display built-in temperature sensor. Installation of an
optional inside air temperature sensor (located in the
return air path) greatly increases the effectiveness of the
de-icing feature, and this option should be considered
whenever the display sensor cannot read the room
temperature accurately.
For additional details on parameter settings and
navigation options, refer to “Selecting a Parameter” on
page 16 and “Navigation Tree” on page 24.
7.2 Choosing the Control Operation
7.1.5 De-icing Cycle (DX Systems Only)
DX systems have a de-icing cycle option to prevent ice
buildup on the evaporator coil during extended periods
of cooling operation. Installation variables, such as
grille sizes, length of ducting, insulation, and ambient
temperatures, determine the runtime required to achieve
the set point.
Factors that substantially increase the runtime include
operating the system with hatches and doors open and
programming an unrealistic set point (e.g. 65 °F/18 °C).
Such situations can cause the evaporator to form ice on
warm humid days.
De-icing is accomplished by closely monitoring the room
air temperature in 10-minute intervals during a cooling
cycle. Depending on the parameter value and the change
in room temperature during these monitoring intervals,
the control performs various actions to prevent ice from
forming or to melt ice that has already formed. This is
accomplished by short compressor shutdown periods
combined with a one-speed increase in the fan speed,
The four Mode indicators represent the different modes
of the control: COOL, DEHUMIDIFICATION, HEAT, and
AUXILIARY HEAT. Refer to “Using the Control Display
Panel” on page 13.

system is in AUTOMATIC mode, switching to cooling or heating as required to satisfy the temperature
set-point. When AUTOMATIC mode is selected, the system provides both heating and cooling, as
required.
The AUTOMATIC mode LED flashes when the optional auxiliary electric heater is in operation.
• The control’s display will indicate AAH.
• The HEAT mode or COOL mode LED also illuminates to indicate whether the unit is cooling or
heating.
• In CW systems, these LEDs indicate the water-valve operating status (open or closed). No watervalve status is indicated when the system is in manual HEAT or COOL modes.
The COOL mode LED illuminates when the COOL mode is selected or when the unit is in an
AUTOMATIC mode cooling cycle. Only the cooling system operates. If the ambient temperature drops
below the set point, the system will not automatically switch to the HEAT mode.
The HEAT mode LED illuminates when the HEAT mode is selected or when the unit is in an
AUTOMATIC mode heating cycle. Only the heating system operates. If the ambient temperature rises
above the set point, the system will not automatically switch to the COOL mode. When the unit is
heating with auxiliary heat, the HEAT mode LED will flash to differentiate from reverse cycle heating.
The DEHUMIDIFICATION mode LED illuminates when the DEHUMIDIFICATION mode is selected.
This mode controls humidity during periods when the vessel is unoccupied and prevents the cabin
temperature from dropping below the minimum default temperature setting.
During humidity control:
• The fan circulates air for 30 minutes.
• Air temperature is sampled and recorded.
• Aer 30 minutes, a cooling cycle starts and continues until the temperature is lowered 2°F (1°C) or
until the cooling cycle runs a maximum of one hour.
• Four hours aer the temperature is satisfied or the cooling cycle times out, the cycle repeats.
For temperature control:
• Aer the 30-minute fan circulation, if the sampled temperature is at or above the factory default
setting 50°F (10°C), a cooling cycle begins and runs for humidity control.
• If the temperature is below 50°F (10°C), a heating cycle begins. The heating cycle continues until
the temperature reaches 50°F (10°C) or until the heating cycle runs a maximum of one hour.
• Four hours aer the temperature is satisfied or the cooling/heating cycle times out, the cycle
repeats, each time determining whether cooling or heating is required.

7.4 Programming the Control
If your AC has a Shaded-Pole (SP) fan motor
I
instead of a Split-Capacitor (SC) High-Velocity
(HV) fan motor, you must change the parameter
P-14 setting to shaded-pole (SP) before operating
the equipment. SP units are recognizable by an
overhanging blower motor. Only reprogram the
fan motor type parameter if you do not have an HV
blower.
14
For CW Only: Standard air handlers come
I
equipped with chilled-water bypass valves.
However, for no-valve air handlers, the fan must be
set to cycle on demand (CYC).
For DX Only: If your air conditioning unit is cool-
I
only (if it does not have a reversing valve), you
must change the parameter P-33 setting from heat
pump (HP) to cool only (CL). Refer to “Selecting a
Parameter” on page 16.
– You must change the parameter before setting the
Automatic mode for a cool-only unit.
EN
Elite Control Operation
– Once this parameter is set, the only allowable
modes are OFF, COOL, AUXILIARY HEAT, and
DEHUMIDIFICATION.
– If the AUTOMATIC mode is selected and the
thermostat calls for heat, the compressor will
run. Since there is no reversing valve, the air
conditioning unit will supply cool air when
heating is desired. Cool-only units do not heat
unless equipped with auxiliary heating.
Parameter settings are used to program and fine-tune
the system for the most efficient operation within an
installation and to adjust operating parameters for your
particular needs. Aer new values are entered and
memorized, the factory defaults are overwritten and the
new parameters become the default values.
Should the Elite lose power, the operating parameters
are retained. When power is restored, the control
resumes operating as last programmed.
The control has factory default values stored in
permanent memory (memorized factory default settings)
that can be recalled if you have any programming
difficulties. You can restore the original factory default
parameters manually. Refer to “Selecting a Parameter”
on page 16 for a summary of the parameters, the
permitted values, and original factory default settings.

Select the parameter setting for the de-icing feature depending on whether you are using the
display built-in temperature sensor or the optional inside air temperature sensor.
• If using an optional inside air temperature sensor., set this parameter to 1 to turn the de-icing feature
ON, or to OFF to disable.
• If using the display built-in temperature sensor, choose one of the two selectable behavior modes:
– 1: assumes the display built-in temperature sensor may be reading the room temperature as
much as 5°F (3°C) greater than the actual evaporator temperature (standard).
– 2: for more extreme installations - assumes the display built-in temperature sensor may be
reading the room temperature as much as 7°F (4°C) greater than the actual evaporator
temperature.
• The setting of 2 should only be used if a setting of 1 does not prevent evaporator ice from forming.
The following applies to soware revision #A13 and older.
I
De-icing is accomplished by switching the reversing valve to HEAT mode while the system
is cooling. The valve remains energized for the programmed cycle time. The cycle is
programmable to OFF or to a period of one, two,or three minutes.
The following applies to soware revision #A15 and newer.
I
De-icing is accomplished by closely monitoring the room air temperature in 10-minute intervals
during a cooling cycle. Depending on the parameter value and the change in room temperature
during these monitoring intervals, the control performs various actions to prevent ice from
forming or to melt ice that has already formed. These actions include short compressor shutdown
periods combined with a one-speed increase in fan speed and by periodic HEAT mode cycles
with the fan turned off.
x OFF
Set this parameter setting when the optional pump sentry water sensor is installed to monitor the
condenser coil temperature and to shut down the pump and compressor when the coil temperature
rises above the programmed value. This sensor is plugged into the H2O OUT sensor jack on the

When this parameter is programmed for auxiliary electric heat, only the electric-heat relay located
toward the middle of the circuit board is energized during a heating cycle.
The following is applicable to soware revision #A15 - #C30.
I
When programmed for auxiliary electric heat, both the electric-heater relay and the valve relay
are energized. This change supports newer circuit board revisions without the electric-heat
relay. Please consult with Dometic Customer Service or with an authorized service technician for
assistance.
– For CW systems: Circuit boards that do not have electric-heat relays require a display with
soware revision A15 or newer to properly energize the compressor relay. Also, when using
this configuration, the electric heater L-1 connection must be connected to the COMP L-1
terminal on the AH-Passport I/O or U-board.
– For DX systems: Circuit boards that do not have electric-heat relays require a display with
soware revision A15 or newer to properly energize the valve relay. Also, since the valve-relay
output only supports a maximum of 15 amps at 115VAC or 10 amps at 230 VAC (PPIO circuit
boards revision F and newer) of resistive load, when installing an optional electric heater that
exceeds this load, it is necessary to install an additional contactor that is rated to handle the
full load of the electric heater.”

x 15°F (8°C) 5°F to 25°F (3° C to 14°C)
Set the temperature differential between the ambient air temperature and the hydronic water
temperature that controls the water valve. For example, selecting 10 °F (-12 °C) opens the valve when
the water temperature is 10 °F (-12 °C ) less than the ambient temperature in the cooling mode and 10
°F (-12 °C ) greater than the ambient temperature in the heating mode.
Careful selection of the temperature differential can fully utilize the ship’s heating and cooling resources.
For example, while in cooling mode and using a 10° F (-12 °C ) value, the valve will open to allow some
cooling while the hydronic system is coming down to temperature. Refer to “Air and Water Temperature
Differential (CW Systems Only)” on page 10 for a graphical explanation of this parameter.

The system runs continuously.
• Check the power source (shore/generator) for proper voltage.
• Check the wiring and terminals for proper sizes and connections.
• Verify with a voltmeter that the power at the unit is the same as the
power source.
A technician should inspect the display, cable, and circuit board. Look for
a red light on the circuit board.
Close all the port holes and hatches. Adjust the set point so it is not too
low for cooling or too high for heating.
Seawater temperature will directly affect the air conditioning unit’s
efficiency. This air conditioning unit can effectively cool your boat in water
temperatures up to 90°F (32°C) and heat (if reverse-cycle option is
installed) in water as low as 40°F (4°C).
• Verify the display location with the criteria found in the installation
section of this manual.
• Install an optional inside air temperature sensor if necessary. If an
optional inside air temperature sensor is already installed in the air
stream, ensure it does not touch anything warm (like the condenser
coil).
Enable de-icing in the parameters. If ice still forms immediately, revisit the
above possible causes.
Ice on a fan coil can be removed quickly by running the unit in HEAT
I
mode.
• Remove any obstructions in the return-air stream.
• Clean the return-air filter and grille.
• Check for crushed or restricted ducting. Ducting must be as straight,
smooth, and taut as possible.
• If the fan speed is set to manual low, raise the speed to a higher setting
or set to automatic mode.
• Or, increase the minimum low speed in the program parameters.
Refer to “The fan coil is iced.” in this table.
Close the hatches and doors.
• Redirect the supply air so that is not blowing in or near the return-air
stream.
• Seal any air leaks on the duct.
Refer to “There is a lack of airflow.”in this table.
