100–120 VAC: 75–105
208–240 VAC: 175–205
Set the built-in voltmeter circuit that monitors the AC input voltage prior to each cooling or
heating cycle.
• For 100–120 VAC input power, set to OFF or 75–105 VAC.
• For 208-240 VAC input power, set to OFF or 175–205 VAC.
P-8 De-icing Cycle
x 1
OFF
1 = ON with 5 °F (3 °C) Display Sensor Differential
2 = ON with 7 °F (4 °C) Display Sensor Differential
Select the parameter setting for the de-icing feature depending on whether you are using
the optional alternate air temperature sensor or the display’s built-in inside air-temperature
sensor.
• If using an optional alternate air temperature sensor, set this parameter to 1 to turn the de-
icing feature ON, or to OFF to disable.
• If using the built-in inside air temperature sensor, choose one of the two selectable
behavior modes:
– 1: assumes the display sensor may be reading the room temperature as much as 5 °F
(3 °C) greater than the actual evaporator temperature (standard).
– 2: assumes the display 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.

Optional Pump
Sentry
x OFF
OFF
ON = Select 100 °F to 150 °F (38 °C and 66 °C)
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 control board.
Program a temperature between 100 °F and 150 °F (38 °C and 66 °C), depending on the
seawater temperature and the system type. Refer to the sensor installation instructions. The
setting increments are in °F even when the Passport control is set to display °C.
P-10
Display Brightness
Control
x x 9 4 (Dimmest)–13 (Brightest)
Set this parameter setting between 4 and 13. A dark cabin requires a setting of 4 or 5. A very
bright cabin requires a setting of 10–13.
P-11
Fahrenheit or Celsius
Selection
x x F
F = Fahrenheit Displayed
C = Celsius Displayed
Select °C for Celsius (Celsius readings are displayed in tenths, for example 22.2°). The
default setting is °F.
P-12
Cycle Pump with
Compressor
x OFF
OFF = Cycle with Compressor
On = Continuous Pump
Select cycled or continuous pump operation.
• OFF: increases the pump life and conserves electricity by cycling on and off with the
compressor.
• ON: programs the pump to operate continuously whenever the system is on.
