Icon Mode and Function
The DEHUMIDIFICATION mode icon illuminates when the DE-
HUMIDIFICATION mode is selected. This mode controls humid-
ity 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 min.
• Air temperature is sampled and recorded.
• After 30 min, a cooling cycle starts and continues until the
• Four hours after the temperature is satisfied or the cooling

ed or when the unit is in an AUTOMATIC mode heating cycle.
Only the heating system operates. If the ambient temperature ris-
es above the set point, the system will not automatically switch to
the COOL mode.
The AUX HEAT mode icon illuminates when the optional auxiliary
electric heater is in operation. If the ambient temperature rises
above the set point, the system will not automatically switch to the
COOL mode.
OFF mode icon. All control outputs are turned OFF. The display
reads OFF. All settings are saved in non-volatile memory.
ON mode icon. All control outputs are on and the display indi-
cates the current state of operation. The display shows the cabin
temperature. All parameters operate as set.
The AUTOMATIC mode icons illuminate when the system is in
AUTOMATIC mode, which switches to cooling or heating as re-
quired to satisfy the temperature set-point. When AUTOMATIC
mode is selected, the system provides both heating and cooling,

as required. The COOL and HEAT indicators or COOL and AUX
HEAT icons are illuminated according to the AUTOMATIC mode.

NOTE For DX systems only: the DEHUMIDIFI-
CATION mode heat cycle will not run when the am-
bient temperature is below 40 °F (4.44 °C). This pro-
tects the condenser coil from freezing. Systems con-
figured with electric heat will run the DEHUMIDIFI-
CATION mode heat cycle regardless of the cabin
temperature.
Icon Mode and Function
The Fan icon allows the user to cycle through all of the different
fan speeds, which include auto and 1–5 (1=low, 2=medium low,
3=medium, 4=medium high, and 5=high). Fan speeds are auto-
matic based on default and programmed values. Program menu
settings P-1 and P-2 decide the maximum and minimum fan speed
settings.
• Fan speed decreases as the temperature set-point is ap-
proached in COOL mode and operates at low speed when
the set point is reached.
• The automatic fan speed operation can be reversed for
HEAT mode when parameter P-12 is set to "rEF". See
gramming the
• Automatic fan mode determines the required fan speed
based on temperature differential. This balances the most
efficient temperature control with a slower, quieter fan
speed. To select automatic fan mode, tap and release the
Fan icon until an "A" appears on the display.
Manual Fan allows the selection of a consistent desired fan speed.
There are five manual fan speeds available: high, medium high,
medium, medium low, and low. The speed number is illuminated
on the display when selected.
• Tap and release the Fan icon to advance from automatic to
manual fan operation.
• Tap and release the Fan icon to cycle through the manual
fan speeds, from low to high.
• Tap and release the Fan icon to return to automatic fan op-
eration.
Use Fan-Only to operate the fan for air circulation when no cool-
ing or heating is desired.
1. From the OFF mode, tap and release the Fan icon to select
a desired fan speed.
Cycled / Continuous Fan mode
The fan can be set to run continuously whenever the system is
turned ON, or it can be set to cycle ON and OFF in conjunction
with the cooling or heating cycles.
1. Tap and hold the Fan icon for five seconds.
CYC displays when the operational setting is set to cycled.
CON displays when the operational setting is set to continuous.
