Description/Mode
Function
COOL
The COOL mode icon 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.
DEHUMIDIFICATION
The DEHUMIDIFICATION
mode icon
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.
HEAT
The HEAT mode icon 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.
AUX HEAT
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
All control outputs are turned OFF. The display reads OFF. All settings are saved in non-volatile
memory.
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.
or
AUTOMATIC
The AUTOMATIC mode icons illuminate when the system is in AUTOMATIC mode, which switches
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 COOL and HEAT indicators
or COOL and AUX HEAT icons are illuminated according to the AUTOMATIC mode.
Wi-Fi
Wi-Fi capable displays have the Wi-Fi icon on the display. Prior to connection, and after enabling
parameter 30, the Wi-Fi icon on the displays flashes white approximately three times per second.
Once the device is connected, the icon illuminates a solid white. Refer to “Using the CapTouch Wi-Fi
Application” on page 21 for information on the full functionality of the Wi-Fi capability.
