OPERATION
•
Heat Mode Indicator - The Heat Mode icon is shown when the heat-only mode is selected or when the unit is in
an Automatic Mode heating cycle.
•
Moisture Mode Indicator - The Moisture Mode icon is shown when the Moisture Mode is selected. This mode
controls humidity during periods when the vessel is unoccupied.
2.
Fan Mode Indicator - Auto or Manual Indicator icon shows when Automatic fan speed or either of the three Manual
speeds are selected.
3.
Power Icon - Press and release to toggle between the On and Off Modes.
4.
Up Icon - Press and release to display the set point. Press and release the Up icon as many times as desired to
increase the set point. Set point increases one degree each time the icon is pressed.
5.
Down Icon - Press and release to display the set point. Press and release the Down icon as many times as desired to
decrease the set point.
6.
Fan Icon - Fan-speed operation is automatic, allowing fan speed to decrease as set-point temperature is approached
in the Cool Mode. The fan operates at low speed when set point is satisfied. Normally the automatic fan speed
operation is reversed in the Heating Mode; however, you can program the fan to operate the same as in the Cooling
Mode. Press the Fan icon to select manual fan speeds if you want to override automatic operation. You can program
the fan to run only during a cool or heat cycle; otherwise the fan runs constantly. Press and release to advance from
Auto Fan to Manual Fan. Press and release the Fan Icon to advance the manual fan speeds, from low to high. Press
and release again to return to the Automatic Fan mode. The selected Fan Mode is indicated by the Fan Indicator icon.
You can change the fan operating mode from Continuous to Cycled by going to Main Menu, Control Parameters,
General Settings, and then Fan Operate Mode.
7.
Temperature Set Point Indicator Icon - Press and release to select from Set point(s), Inside, Outside, or Service/
Water temperatures
8.
Main Menu Icon - Press the Menu icon to show the Main Menu page.
9.
Status/Schedule Icon - Press the Status/Schedule icon to view any fault occurring in the system.

When the control is in Off Mode, all control outputs are turned off. All settings are saved in nonvolatile memory.

When the control is in On Mode, power is supplied to the appropriate outputs and the display indicates the current state of
operation. The operating and program parameters resume based on those last stored when the unit was operating.

UTOMATIC
When Automatic Mode is selected, the system provides both heating and cooling as required. The Auto Mode icon is shown.
Cabin temperature in a given mode is maintained within 2°F (1.1°C) of set point by default. (See "General Settings, Set Point
Temperature Differential" on page 12 for instructions on how to reduce this variation to 1°F [0.55°C].) If the system was most
recently cooling, the cabin temperature must drop below the set point by at least 4°F (2.2°C) in order for the system to switch
from cooling to heating. Similarly, if the system was most recently heating, the cabin temperature must exceed the set point by
at least 4°F (2.2°C) in order for the system to switch 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.

When Cool Mode is selected, the Cooling mode icon is shown and only the cooling system operates as required. If the ambient
temperature drops below the set point, the system will not automatically switch to the Heat Mode.

When Heat Mode is selected, the Heating mode icon is shown and only the heating system operates as required. If the ambient
temperature rises above the set point, the system will not automatically switch to the Cool Mode.
