Webasto BlueCool Premium
Chilled Water Marine Air Conditioning Systems
General information
Dear Webasto Customer!
These Operating Instructions provide an overview about how to use the chilled water air
conditioning system and its control panels. An extensive documentation and description can
be found in the Installation and Service Instructions.
To ensure safe use of the appliance, ALWAYS read and follow all instructions
in this manual. It is very important that an authorized Webasto dealer carries
out any repair or maintenance not described in this manual.
Safety notes
In general, all A/C (air conditioning) systems are running on 230 or 115 Volt AC. For all work
at any of the components like pumps, compressor, blowers or electronics, the power
connection has to be interrupted. All work at the electric wiring must be performed by
specialized installers.
Before starting the air condition system, check the following points:
• The closing valve at the sea-cock is open!
• The sea-water strainer is clean and filled with water!
• The boat has enough water under the body and the sea-cock is not blocked!
• All supply and return air grilles are open and not blocked by luggage, clothing or anything
else!
• After turning the system on, water comes out of the over-board discharge. If not, switch
off the system and check the sea-water circuit again!
Designated Control Panels
The chiller unit is operated and controlled by the Chiller Control digital control panel.
Directly connected air handlers for one cabin are also operated by this control panel.
Other cabins with indirectly connected air handlers are controlled by separate Cabin
Control digital control panels.
The system must be started with the Chiller Control prior to normal functionality of
the air handlers in other cabins.

Chiller Control:Start and stop of the chiller unit
• Programming and setup of the chiller unit
• Setup of directly connected air handlers
• Selection of operation mode (Automatic, Cooling, Heating)
Cabin Control:
• Start and stop of indirectly connected air handlers
• Temperature and blower setting for indirectly connected air handlers
The operation mode can not be selected with the Cabin Control!
The digital control panel is always factory pre-programmed and the secondary commands are
code-protected.
• If your chilled water system has a heating option, the cabins can be heated until the sea-
water temperature drops below 6 °C (43 °F).
The function „Automatic with Reverse Cycle” (F3) is pre-set.
• If an external water heater is integrated in your chilled water system, you can heat inde-
pendently from the sea-water temperature (See separate heater documentation for further
details).
The function „Automatic with External Heater” (F4) is pre-set.

Operating the „Chiller Control“
When the air conditioning is connected with the electrical power, the system initializes itself.
The display shows Init and afterwards the frequency, e.g. 50 Hz.
Starting
Press once the button.
On is displayed and after appr. 20 sec. the current room temperature, e.g. 28.5 (°C) (83 ºF)
is shown.
Setting the temperature
With the buttons and between 15 °C (59 ºF) and 29 °C (84 ºF) while the room tem-
perature is displayed.
e.g. room temperature 25 °C (77 ºF)
Set temperature = 20 °C (68 ºF), Cool mode starts.
Set temperature = 29 °C (84 ºF), Heat mode starts.
Attention: Only the mode that is preselected by the Chiller Control can be started.
Setting blower speed
Press the button until b is shown to the left and the selected value to the right, e.g. b 05
(blower speed 5)
• Value Range (Blower speeds): 1-2-3-4-5 and A
• Factory Setting: A (Automatic blower speed)
Set value with the buttons and . Your setting issecured.
 In the automatic blower speed mode (b A) the blower start and operation depends on
the temperature. If there is no need for blower operation, the display shows ba11. It can
take some time before the blower starts.
Displaying the chilled water temperature
Press the button until H is shown to the left and a numerical value to the right, e.g. H10.5.
Check if the current operation mode is functioning properly.
 Cool mode (LED snow flake)= Chilled water temperature drops constantly
 Heat mode (LED sun) = Chilled water temperature rises constantly
Access to further program levels
Press the button until code is displayed. With a special access code specific settings can
be modified (by the installer).
Further information can be found in the Installation Instructions.

„Cabin Control“ for indirectly connected air handlers

Error code display and actions
The error codes are viewed on the display screen. After the error codes are displayed, the sys-
tem is shut off for 60 sec. and re-started (except for ba11). If the same error occurs more than
6 times within 60 minutes, the A/C system will be completely stopped. In this case, it can only
start again if the error has been solved and the system has been completely switched off and
on again.

Instructions for further details.)

Warranty claims
Failure to follow the Installation Instructions and the information, recommendations and
descriptions therein will void all warranties. The same applies if repairs are carried out
incorrectly, with the use of non-genuine parts or by unauthorized personnel. Warranty claims
are only valid if the claimant can verify that he has complied with the maintenance and safety
instructions.
Maintenance
Check daily:
• sea-water strainer, clean it and remove any debris if required.
Check monthly:
• air filter in the return air grilles (where applicable) and clean if necessary.
• sea-water circuit for leaks in the whole system from the sea-cock to the sea-waterexit.
• condensation drain for free flow and leaks.
• air-ducting for damage, interruption and free flow.
• function of the system by having it run for at least 10 minutes.
Check yearly:
• electrical connections for corrosion of contacts and to ensure that they are secure.
Winter storage
• At frost temperatures the whole sea-water circuit must be emptied and the sea-water valve
closed.
General Recommendation
When leaving the boat unattended for a longer period close all sea-water valves.
