Operation Elite Control
– Display LEDs illuminate to indicate the selected
mode.
– The display locks into the last mode selected after
five seconds of inactivity, then displays the room
temperature. The selected mode LED remains lit.
– After 3 seconds of inactivity, the display shows the
room temperature and enters the IDLE state.
– To indicate an OFF state, all the display LEDs turn off.
– When the display is making a call for heating,
cooling, auxiliary heat, or humidity, the appropriate
Mode indicator illuminates (and flashes for auxiliary
heat).
2. Press the Power button to wake up the control from
the OFF state.
Available Modes and Options for Operation
Icon Description/Mode Function
AUTO
AUTOMATIC
The AUTOMATIC mode LED illuminates, together with the HEAT or COOL mode LED, when the
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.
AUTOMATIC with
Auxiliary Heat
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 water-
valve status is indicated when the system is in manual HEAT or COOL modes.
COOL
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.
HEAT
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.
DEHUMIDIFICATION
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.
• After 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 after the temperature is satisfied or the cooling cycle times out, the cycle repeats.
For temperature control:
• After 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 after the temperature is satisfied or the cooling/heating cycle times out, the cycle
repeats, each time determining whether cooling or heating is required.
I
For DX systems only: the DEHUMIDIFICATION mode heat cycle will not run when the ambient
temperature is below 40 °F (4 °C). This protects the condenser coil from freezing. Systems
configured with electric heat will run the DEHUMIDIFICATION mode heat cycle regardless of
the cabin temperature.
ON
All control outputs are on and the display indicates the current state of operation. The display shows
the cabin temperature. All parameters operate as set.
