Pump Sentry
Set this parameter setting when the optional pump sentry water
sensor is installed to check the condenser coil temperature and
to shut down the pump and compressor when the coil tempera-
ture rises above the programmed value. This sensor is plugged
into the H2O OUT sensor jack on the control board.
Program a temperature between 100.0 °F ... 150.0 °F
(37.77 °C ... 65.55 °C) , depending on seawater temperature
and the system type. Refer to the sensor installation instructions.
The setting increments are in °F even when the control is set to
display °C.

Select heat pump or cool-only operation.
• Selecting"HP" operates the unit in the default heat pump
mode, which allows for cooling, reverse cycle heating, or
(optional) auxiliary electric heat.
• Selecting "CL" operates the unit in COOL or (optional) AUX
HEAT modes.
• AUX HEAT mode is only available if the unit is equipped
with an auxiliary electric heater.

Water Valve
Forced Open
Open the water valve to bleed air from the system.
• OPn: forces the valve open for four hours while the control
is turned OFF. If the control is turned ON or if AC power is
interrupted during this four‑hour period, the valve over-
ride is canceled.
• nOr: returns the valve to normal operation.
P-17
Water Tem-
perature Dif-
Set the temperature differential between the ambient air temper-
ferential
ature and the hydronic water temperature that controls the water
valve. For example, selecting 10 °F (– 12.22 °C) opens the valve
when the water temperature is 10 °F (– 12.22 °C) less than the
ambient temperature in the cooling mode and 10 °F (– 12.22 °C)
greater than the ambient temperature in the heating mode.
Careful selection of the temperature differential can fully use
the ship's heating and cooling resources. For example, while in
cooling mode and using a 10 °F (– 12.22 °C) value, the valve will
open to allow some cooling while the hydronic system is coming
down to temperature.

NOTE Selecting "CL" initiates a five-minute com-
pressor delay when the compressor shuts down on
the set point, a fault, or a power outage. The five-
minute delay begins immediately after the compres-
sor shuts down. The COOL mode icon on the dis-
play flashes once per second for five minutes or for
the remaining time to complete the five minutes af-
ter the last cycle end time. If the five-minute delay
period has passed before the compressor is called
to operate, the compressor comes on with no de-
lay.
