The BlueCool V-Series air-conditioning system is operated with the control
element that enables access to all functions for normal operation of the air condi-
tioning system.
3.1 Directly connected air handlers
The central digital chiller control element not only controls the general operati-
on of the chiller unit but can also directly control the air handlers located in the
saloon and/or in the cabin (where the main cabin temperature sensor is located).
This direct air handler control function is not available in all installations.
NOTE!
When an air handler is connected directly to the BlueCool V-Series
chiller it acts as the reference and governs whether the system is to
heat or cool in automatic mode.
The secondary air handlers can only be operated in the same operating mode
(heating or cooling) as the chiller unit as the unit can either only heat or cool at
any one time.
NOTE!
By using electrical heating elements in the secondary air handlers
individual cabins can be heated while the overall system operates in
cooling mode.
3.2 Operation
All fans connected directly to the chiller electrical box are started when the ope-
rating mode LED lights up. The fan control facility checks whether the cold water
circuit is at the required temperature. Example: In cooling mode at a set tempe-
rature of 21°C, the fan speed in automatic operation remains at level 1 until the
temperature in the cold water circuit is lower than 21°C. This prevents the fan
starting up too early if the temperature in the cold water circuit is unsuitable.
The digital chiller control element can completely shut down fan operation, e.g.
at night, while the other air handlers on the boat continue to operate. The fan
control is completely independent of compressor operation.

3.3 Switching on central chiller unit and air handlers
After connecting the voltage supply, first all LEDs and all segments of the numeric
display flash for a few seconds, then "INIT" briefly appears on the control ele-
ment. The display “50H” or “60H” follows, depending on which power supply
the air-conditioning system is operated on, for example 230 V/50 Hz or
230 V/60Hz.
If the system was switched on before cutting off the voltage supply, the current
cabin temperature in the reference cabin will appear on the control element and
the system will start up automatically in the set operating mode. Otherwise the
control panel will go dark and the air-conditioning system will assume standby
mode.
• Switch on the system by pressing the "On/Off" button (6).
Depending on the requested operating mode, either the LED indicator for heating
mode (7) or the LED indicator for cooling mode (9) lights up to show the active
mode. The LED indicator for automatically switching between operating modes
(8) shows whether switchover takes place automatically. Automatic switch-over
is dependent on the set temperature and the cabin temperature measured by the
cabin temperature sensor.
After a further 10seconds the 4/2-way reversing valve (that allows the air-condi-
tioning system to operate as a chiller unit (cooling) or as a heat pump (heating))
opens to equalise pressure in the refrigerant circuit. After another 10seconds the
sea water pump starts up followed by the compressor. This is followed by normal
operation.
3.4 Switching off system
The system can be switched off by pressing the "On/Off" button (6). The
condition for this is that the user is in the start menu with the display of the cabin
temperature. On the programming level (temperature, fan), the "On/Off" but-
ton (6) is used to confirm the setting and not to switch off the system.
7
3.5 Selecting cooling mode/heating mode
The system selects cooling or heating operating mode depending on the required
temperature. The prerequisite is that the system has been configured for automa-
tic switch-over between cooling and heating. For information on configuring the
operating modes please contact your authorised Webasto Marine dealer.
3.6 Setting setpoint temperature
• Set the setpoint temperature in accordance with your own preferences.
• Press the Plus button (2) or Minus button (3).
The setpoint temperature is displayed.
• Press the Plus button (2) or Minus button (3) to change the setpoint
temperature.
• Confirm the entry by pressing the “On/Off” button (6) or wait at least 5se-
conds so that the entered value is automatically adopted.
3.7 Standby mode
The control element will assume standby mode if no button is pressed for
5minutes. The corresponding operating mode LED will then flash discretely every
20seconds. Press any button to return to the normal display.
3.8 Activating Eco mode
With the Eco mode function it is possible to continuously operate the BlueCool
V-Series under modulating partial load, thus limiting the current consumption of
the system. This makes it possible to operate the system with a lower generator
output, parallel with other large electrical loads such as hot water boiler or with
weak on-shore power supply.
8
Press the function button to activate Eco mode. Press the plus or minus but-
ton repeatedly to select the maximum output level at which the system is to operate.
• Switching on system
• Press the function button (5) once
• Eco 0 is shown
• Press the button (2) to change the setting to Eco 1 or Eco 2
• Press the button (1) to return to the Eco 0 setting
Confirm the entry by pressing the "On/Off" button (6).
Eco 0: 100% of rated output
Eco 1: 80% of rated output
Eco 2: 45% of rated output
Activated Eco mode is indicated by the display alternately showing Eco1 and Eco2
as well as the set temperature.
Eco mode is never exited automatically but requires operator intervention.
Check the Eco mode setting if you find that the cooling output of the BlueCool
V-Series is unsatisfactory.
Refer to Section 4 "Malfunctions" for further information on reduced cooling
output.
3.9 Set the fan speed
• Switching on system.
• Press the fan setting button (4).
The current fan speed is displayed.
• Press the Plus button (2) or Minus button (3) to change the fan speed.
• If the Plus button (2) is pressed again when the highest speed has already
been selected, automatic fan mode is switched on and “b A” appears on the
control element. Pressing the Minus button (3) exits the automatic fan
mode and returns to the manual mode.
Confirm the entry by pressing the “On/Off” button (6) or wait at least 5 se-
conds so that the entered value is automatically adopted.

Further setting options for the BlueCool air-conditioning system are reserved for
the technician and require an access code.
4 Malfunctions
4.1 Troubleshooting
CAUTION
Troubleshooting only by professionals!
Troubleshooting requires comprehensive knowledge on the
design and operation of the individual components of the air-
conditioning system and may only be carried out by authorised
professionals trained by Webasto for this purpose.
If malfunctions occur, the system must be switched off.
4.2 Malfunctions that are displayed
The following malfunctions are displayed directly on the digital control element
as a code (e.g. A02). Each time one of these fault codes appears, the system is
stopped for approx. 60 seconds and then a restart is attempted. If a malfunction
occurs more often than 6 times consecutively within 30 minutes, the system is
completely shut down and the fault code is displayed continuously. No further
restarts are attempted and the user should have the fault rectified and then reset
the system by switching it off or by temporarily interrupting the voltage supply to
the system.

AAA Undervoltage Switch-off in case
of undervoltage.
Voltage supply be-
low set undervolt-
age value for longer
than 5seconds. The
cause is probably
excessively long
power cable for the
on-shore connec-
tion, overloading
or an insuciently
high power genera-
tor output.
Use a on-shore power
connection with a more
stable voltage supply. Use
a shorter power cable for
the on-shore connection.
Switch off other electrical
loads. Please contact
