4 Proper use
The Marine Climate System is an air conditioning system designed for use
on boats or yachts. It can cool down or warm up the interior of the boat or
yacht.
5 Technical description
The Marine Climate Systems MCS6, MCS12 and MCS16 are marine air
conditioners which can be used for variable air conditioning inside a boat or
a yacht. They can cool and warm the room.
The Marine Climate System consists mainly of the air conditioning unit and a
control panel. A refrigerant gas is circulating through the system which is sea-
water cooled.

7 Operating
7.1 Initial startup
ANOTICE!
Do not turn the unit off and immediately turn it back on. Allow at
least 30 s for refrigerant pressure equalization.
➤Ensure seawater intake ball valve (seacock) is open.
➤Make sure the control is powered OFF.
➤Turn on air conditioner circuit breaker.
➤If the seawater pump has its own circuit breaker, turn that on too.
8 LED “Fan Indicator” This LED is lit when a Manual Fan Speed is
selected.
9 LED “Cool Mode” This LED is lit when
– the Cool Only Mode is selected
– or when the unit is in a cooling cycle.

➤Press the Fan Button (fig. 12, page 2).
✓This energizes the fan.
➤Verify that the fan is running and that there is steady airflow out of the sup-
ply-air grille.
➤Select a temperature set point lower than the current cabin temperature.
✓This starts the compressor and seawater pump.
➤Check for a steady solid stream of seawater from the overboard
discharge.
➤If the unit does not appear to be operating properly, refer to trouble-
shooting guidelines (“Troubleshooting” on page 23).
7.2 Overview
Power On
➤Press the Power button (fig. 11, page 2) once to engage the system.
✓The display indicates room temperature when the system is on and is
blank when the system is off.
Set Temperature
➤Press the Up or Down button (fig. 13 and 4, page 2) to set the desired
room temperature.
The set point can be viewed by momentarily pressing and releasing the
Up or Down button.
Fan Speed
Fan-speed operation is automatic, allowing fan speed to decrease as the set
point temperature is approached in the Cool Mode. The fan operates at low
speed when set point is satisfied.
➤Use the Fan button (fig. 12, page 2) to select manual fan speeds.
You can program the fan to run only when cooling or heating is required. Nor-
mally the automatic fan-speed operation is reversed in the Heating Mode,
however, the fan can be programmed to operate the same as in the Cooling
Mode.

Memory
The control’s nonvolatile memory requires no batteries or backup power.
When power is lost, the operating parameters are retained indefinitely. When
power is restored, the control resumes operating as last programmed.
7.3 Modes of Operation
Off Mode
When the Marine Climate System is in the Off Mode, all control outputs are
turned off. Program parameters and user settings are saved in nonvolatile
memory.
On Mode
When the Marine Climate System is in the 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 stored the
last time the unit was operating.
Cool Mode
When Cool Mode is selected, the Cool Mode LED is lit and the cooling
systems are operated as required. When the temperature drops below the
set point, the system will not automatically switch to the Heat Mode.
Heat Mode
When the Heat Mode LED is lit, only the heating systems are selected and
operated as required. Should the temperature rise above the set point, the
system will not automatically switch to the Cool Mode.
Automatic Mode
Automatic Mode provides both heating and cooling as required. The Heat or
Cool LED will be lit according to the mode required.
Temperature in a given mode is maintained within 2 °F (1.1 °C) of set point,
however a 4 °F (2.2 °C) difference is required to allow the Marine Climate
System to change modes.
Once the mode changes temperature will be maintained within 2 °F (1.1 °C)
of set point.

Manual Fan Mode
Manual Fan Mode allows to select the desired fan speed manually. When a
manual fan speed has been selected, the Fan LED will be lit. Manual Fan
Mode is sometimes preferred when room temperature is constantly changing
due to varying heat loads.
The fastest fan speed is represented by “6”, the slowest represented by “1”.
➤Press and hold the Fan Button during normal operation to select one of
the six manual fan speeds available.
Circulation Mode
When the system is off at the control panel the fan can be used to only
circulate the air.
➤Press and hold the Fan Button when the display is off until the desired
speed number appears in the window.
➤Release the Fan Button
✓The fan will run at the selected speed circulating the air without heating or
cooling.
➤Press the Power Button once to cancel the Circulation Mode and enter the
On Mode.
Moisture Mode
➤While in the On Mode simultaneously press the Power and Down Buttons.
✓The first cycle will start in one minute.
➤Press the Power Button to end the Moisture Mode.
✓The “HU1” mnemonic code is displayed while in the Moisture Mode.
Program Mode
INOTE
The program mode can only be entered from the Off Mode.
The Program Mode is used to adjust the systems operating parameters to
suit the particular needs of individual users. The Program Mode is also used
to tailor the air conditioning system for the most efficient operation within an
installation.
