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 MCS T6, MCS T12 and MCS T16 are marine air condi-
tioners 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 is circulating through the system which is seawater cooled.

7Operating
7.1 Initial startup
A
➤Ensure seawater intake ball valve (seacock) is open.
➤Turn on air conditioner circuit breaker.
➤If the seawater pump has its own circuit breaker, turn that on.
➤Press the Fan Button (fig. 12, page 3).
✓This energizes the fan.
➤Verify that the fan is running and that there is steady airflow out of the supply-air
grille.
➤Select a temperature set point lower than the current cabin temperature.
✓This starts the compressor and seawater pump.
NOTICE!
Do not turn the unit off and immediately turn it back on. Allow at least
30 s for refrigerant pressure equalization.

➤Check for a steady solid stream of seawater from the overboard discharge.
➤If the unit does not appear to be operating properly, refer to troubleshooting
guidelines (“Troubleshooting” on page 24).
7.2 Overview
Power On
➤Press the Power button (fig. 11, page 3) 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 3) 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 3) to select manual fan speeds.
You can program the fan to run only when cooling or heating is required. Normally
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 appro-
priate 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 1.1 °C (2 °F) of set point, however
a 2.2 °C (4 °F) difference is required to allow the Marine Climate System to change
modes.
Once the mode changes temperature will be maintained within 1.1 °C (2 °F) 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”.
