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
display built-in temperature sensor or the optional inside air temperature sensor.
• If using an optional inside air temperature sensor., set this parameter to 1 to turn the de-icing feature
ON, or to OFF to disable.
• If using the display built-in temperature sensor, choose one of the two selectable behavior modes:
– 1: assumes the display built-in temperature sensor may be reading the room temperature as
much as 5 °F (3 °C) greater than the actual evaporator temperature (standard).
– 2: for more extreme installations - assumes the display built-in temperature 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.
I
The following applies to software revision #A13 and older.
De-icing is accomplished by switching the reversing valve to HEAT mode while the system
is cooling. The valve remains energized for the programmed cycle time. The cycle is
programmable to OFF or to a period of one, two,or three minutes.
I
The following applies to software revision #A15 and newer.
De-icing is accomplished by closely monitoring the room air temperature in 10-minute intervals
during a cooling cycle. Depending on the parameter value and the change in room temperature
during these monitoring intervals, the control performs various actions to prevent ice from
forming or to melt ice that has already formed. These actions include short compressor shutdown
periods combined with a one-speed increase in fan speed and by periodic HEAT mode cycles
with the fan turned off.
P-8 Optional Pump Sentry

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 seawater
temperature and the system type. Refer to the sensor installation instructions for detail. The setting
increments are in °F even when the control is set to display °C.

x x 4 (Dimmest)–18 (Brightest)
Set this parameter setting between 4 and 18.
A dark cabin requires a setting of 4. A very bright cabin requires a setting of 12–18.

F = Fahrenheit Displayed
C = Celsius Displayed
A = Automatic Selection Based on Voltage
50 Hz = Celsius
60 Hz = Fahrenheit
Select °C for Celsius. (Celsius readings are displayed in tenths, for example 22.2°). The default setting is °F.

Cycle Pump with
Compressor
x CYC
CYC = Cycle with Compressor
Con = Continuous Pump
Select cycled or continuous pump operation:
• CYC: increases the pump life and conserves electricity by cycling ON and OFF with the compressor.
• Con: programs the pump to operate continuously whenever the system is on.
P-12
Reverse Automatic Fan
Speeds During Heating
x x rEF
nOr = Normal Fan Operation
rEF = Reversed Fan in HEAT Mode
Reverse the automatic fan speeds during HEAT mode to improve heat output in cooler climates.
• When set to rEF, the fan speeds up as the set point is approached. The fan switches to low speed
when the set point is satisfied and the water valve or compressor cycles OFF.
• When set to nOr, the fan operates the same as during cooling, which represents normal fan operation.
