Operation Manual
WEBASTO BLUE COOL CLASSIC
Compact Air Condition Systems
General Information
Dear Webasto Customer!
This operation manual provides an overview about how to use the compact air condition system
and its control panel. An extensive documentation and description can be found in the installation
and service manual.
Safety Notes
In general, all A/C systems are running on 230 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 switching on, water comes out of the over-board discharge. If not, switch off the system
and check the sea-water circuit again!
The control panel „Air-Control“ for Compact Systems
The digital control panel is always factory pre-programmed and the secondary commands are
code-protected.
•If your Compact air-condition system has a heat cycle (easily detectable by the magnetic valve
next to the compressor), the cabin(s) can be heated until a sea-water temperature of about
10°C. The control panel will be pre-set with the function „Automatic“.
•If your air-condition does not have a heat cycle, the function „Cooling“ is pre-set.

Operating the Air-Control for Compact Systems
When the air-conditioning is connected with the electrical power, the system initialises 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) is shown. Depending on the room and set-point temperature the
appropriate mode will start. Mode indication by LED.
→A malfunction is indicated by a blinking error code (see below)
→ba11 is no error code that causes a system stop (see below)
Setting the
Temperature With the buttons and between 15°C and 29°C while the room -
temperature is displayed.
Air-condition without heat cycle
→the set temperature must be below the room temperature.
e.g. room temperature 25° C
Set temperature between 15°C and 24°C.
•Air-condition with heat cycle
→the set temperature can be between 15°C and 29°C.
e.g. room temperature 25° C
Set temperature = 20°C, Cool mode starts.
Set temperature = 29°C, Heat mode starts.
Setting Blower
Speed Press the button until bis shown to the left and the selected value to
the right, e.g. b 5 (Blower speed 5)
•Value Range (Blower speeds): 1-2-3-4-5 and A
•Factory Setting: A(Automatic Blower Speed)
Program with the buttons and . Confirm by pressing the button.
Secure your setting by pressing the button. The display shows memo
and then the room-temperature.
→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.
→The manual blower speed mode (1 to 5) is indicated by the LED
„Manual blower operation“.
Displaying the
Evaporator
Temperature
Press the button until Eis shown to the left and a numerical value to
the right, e.g. E10.5. Check if the current operation mode is functioning
properly.
→Cool mode (LED snow flake) = Evaporator temperature drops constantly
→Heat mode (LED sun) = Evaporator 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 manual.

Error code display and actions
The error codes are viewed on the display screen. After the error codes are displayed, the system
is shut off for 60 sec. and re-started (except for ba11). If the same error occurs within 30 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.
Error codes and causes
AAA Persistent low voltage (below 195 Volt for more than 5 sec.)
A01 Low pressure cut-out compressor 1
→Not enough refrigerant in the system, please inform service station.
→Sea water temperature in heat mode too low (<7°C), heat mode not
possible.
A02 High pressure cut-out compressor 1
→Sea water circuit interrupted, please check circuit.
→Too much refrigerant in system, please call service station.
→Sea water temperature in heat mode too high (>17°C), heat mode not
possible.
A03 - 08 Not applicable for “Classic” systems
A09 Room temperature sensor (external or internal) defective or absent.
A10 Temperature sensor at evaporator defective or absent.
CA11 All compressors have been deactivated. Re-activate with the code menu
EA11 Compressor stopped by de-icing control. Automatic re-start. This error is
only visible in the evaporator temperature read-out E10.0.
Warranty claims
Failure to follow the installation manual 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 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 water exit.
•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.
Winter storage At frost temperatures the whole sea water circuit must be emptied and the
sea water valve closed.
