Webasto BlueCool Classic Series AC Systems OVERVIEW

Description and operation

Self-Contained Air Conditioning Unit

ATTENTION All Webasto air conditioning units pump seawater around the condenser to aid in the cooling process.

Cooling CycleThe compressor compresses the refrigerant gas which is then condensed to liquid as it passes through the seawater cooled condenser. The liquid refrigerant is injected through a small nozzle and evaporates. This evaporation process produces the refrigeration effect. The evaporation takes place in a tubular finned coil (also called: evaporator coil). A blower forces the air through the evaporator coil. While passing through the evaporator the temperature of the air is lowered by approximately 15 °C (59 °F).

Heating Cycle (option)

ATTENTION The heat cycle becomes inefficient when the outside water temperature drops below 6 °C (43 °F) approx.

It is quite possible to produce heat with an air conditioning unit. For this purpose the unit shall be equipped with a 4-way reversed cycle valve (option). During the heat cycle the condenser effectively becomes the evaporator. It removes any available heat from the seawater and transfers it to the refrigerant. The finned evaporator becomes the condenser and produces heat to approx. 45/50 °C (113/122 °F).

Digital Display Panel

All Webasto air conditioning units are controlled by a Digital Display <AIR CONTROL> which gives access to all functions necessary for the normal operation of the unit and attached accessories (blowers, pumps, etc.).In order to start the system you only need to press the <On/Off> key on the digital display. From there on the electronic control unit takes care of the progressive starting up of the air conditioning unit as well as its normal functioning.The digital display will show the present air temperature of the cabin in which the digital display is situated or where the main temperature sensor is located (in case it is placed in a different room). After a delay of approx. 20 seconds the display will indicate the cycle in which operation the unit will start i.e. <COOL> or <HEAT>. The choice will depend upon the setpoint temperature and the air temperature as measured by the external air temperature sensor.After a further delay of approx. 50 seconds the compressor(s) will start up and the normal operation cycle will begin.

2004 Series Digital DisplayThe WEBASTO <AIR CONTROL> digital display gives access to information and controls at three distinct levels:

Immediate Access - Level 1

1. Room temperature readout in the main 4 LED display window

2. 3 small LED’s to the left indicating the operating cycle presently active: cool cycle only operation; automatic cycle (switching governed by the end user’s entered setpoint temperature); heat cycle only operation.

3. 2 setpoint keys give immediate access to the thermostatic setpoints for blower control (“Sun”and “Snow”keys). These keys are also used to alter programming values.

Secondary commands and info -Level 2The F/Blower key gives immediate access to a number of secondary commands which need to be accessed frequently for day to day operation. First access is to the blower speed control, then evaporator temperature readout, etc.

Programming Commands - Level 3A number of programming commands that do not need to be accessed for day-to-day operation are hidden and require a special procedure to enable access and modification (See Programming Access). An access code can be enforced to avoid accidental modification of programming values.

Startup delayAfter pushing the On/Off key the LED’s will display <On> while initializing the system. Push again to stop operation; the display will briefly show <Off> before extinction. The appropriate LED to the left (heat, cool, etc.) will come on after approx.15 seconds and compressor operation will start after approx.50 seconds. The seawater circulation pump will come on approx. 9 seconds before compressor startup.

Modification of setpoint temperatureThe setpoint temperature, i.e. the temperature desired by the operator for blower operation can be modified as following:

1. Press and hold one of the setpoint selector keys and wait until the new desired setpoint temperature is obtained.

2. Press <On/Off> key to memorize. The display will return to normal room temperature readout after approx. 5 seconds. Non-volatile memory keeps last settings.

Special Features - 2004 Series

A) Dedicated Blower speed key: The 2004 Digital Display provides for a dedicated blower speed key which allows you to cycle through the speed settings. The <F> key from 2004 onwards is only used for programming and setting purposes.

B) Self-priming pumps: WEBASTO Marine has developed a variable flow ultra-silent self-priming pump system. This will automatically adjust its flow rate to the real required capacity, i.e. during a hot sunny afternoon the pump will run at full speed, during the night it will slow down to minimum speed. This system is referenced: WEBASTO WB200; it is basically a DC pump with a special control unit between the TCC controller card and the pump allowing to adjust the pump speed as needed. The use of standard 115V/230VAC pumps is still possible without any restriction. Installation of WB200 pumps can be above the waterline to 250 mm approx.Flow rate varies between 6 and 12 L/min. approx.

8

9

C) Automatic blank/sleep mode programmable time delay: Factory default:15minutes. While in blank/sleep mode the cycle LED flashes discretely every 20 seconds. To go back to normal operation push any key. D) Calibrate all blower speed settings in real time mode: It is possible to calibrate all speed settings (1 to 5) before actually putting the system into service (See Blower Speed Setting Calibration).

CAUTION! Never program speeds so low that the blower is in danger of stopping or will not restart at that setting. This will inevitably entail motor winding burnout and will not be covered by the WEBASTO warranty.

E) Automatic Deicing Control: During intermediate seasons (spring, autumn) when moderate temperature conditions prevail, there is a definite risk of icing the evaporator coil in cool mode and pressure safety cut-outs in heat mode. To allow maximum blower speed variation and still function within a normal operating window, the TCC card is equipped with a second temperature sensor which reads the exact evaporator coil temperature. Whenever coil temperature approaches the danger zone, blower speed is increased to half speed; if that is not sufficient the micro-processor will stop compressor operation for pre-determined intervals and will resume normal operation when coil temperature has moved back to within normal operating values. This feature is completely transparent to the end user. When this happens, code <tA11> can be seen in the display instead of evaporator coil temperature. Press <F> key (5) to read out evaporator coil temperature or code <tA11>.

F) Infrared Remote Control: Infrared remote control can be obtained as an option. This remote control is based on the standard protocols also used by TV and other appliances. Although the WEBASTO controls have been chosen so as to avoid interference with most TV models, the end user should be aware that in certain cases interference may occur with TV sets or other appliances. In general, it is therefore advisable to avoid locating a WEBASTO Air Control panel next to other appliances using infrared control units.

G) Access Code: The end user can deny access to all program settings by introducing an access code (see Programming Access - code ). Blower speed and setpoints always remain accessible. Once an access code is validated, the digital panel will show <CODE> if the end user tries to access functions other than blower speed or setpoint. To gain full access push the sun key to reach the code value as programmed and push the F/Blower key again to gain access to full program settings.

Secondary CommandsThe <F> key gives immediate access to settings and displays necessary for day-to-day operation. When pushing the <F> key you will see a code which indicates the setting or the present value.

The following is a list of commands / displays In order of appearance:

Table 1 Secondary Commands

Blower speed control (0,1,2,3,4,5) A = automatic blower speed adjusted to temperature differential.1 to 5 = manual speed control Note: Speed control is in real time mode i.e.changes are effective immediately without any validation procedure.

ATTENTION The following functions need validation before a new value is accepted. Press the <F> key and go to the next function line. Validation will occur automatically when the display goes back to room temperature readout. Validation can be forced by pushing the On/Off key while in F mode. and is confirmed by the message <MEMO>.

11

Central Blower ControlThe central <AIR CONTROL> digital display also directly controls the blower of the evaporator. For all WBCC systems, there are two modes of blower control and operation: thermostatic interruption of blower operation as soon as the desired setpoint temperature has been reached; un-interrupted blower operation regardless of thermostatic compressor control. The choice between these two functioning modes can be programmed directly by the end user. The digital control is initially programmed by the manufacturer in second - i.e. un-interrupted blower operation. Blower control can be manual with 5 different speed levels or automatic; in this case blower speed will be governed by the temperature differential with the setpoint temperature.

Webasto BlueCool Classic Series AC Systems INSTALLATION

INSTALLATION

Installation and Positioning of BlueCool Classic unit Location: BlueCool Classic units are designed to be installed in any convenient location. The unit is normally placed in the living areas. The unit will produce condensation so a drain line from the drain pan is needed in these installations. The space around the unit can be insulated to reduce noise if desired. The unit is internally cooled and does not require additional ventilation. The location selected should provide for access to refrigerant, seawater, and electrical connections and be accessible for service. It should be installed on a flat, horizontal surface away from direct spray from engine air intakes or water wash-down.

Location checklist • Adequate space for access to refrigerant, seawater and electrical connections.• Accessible for service and maintenance.• Flat, horizontal surface.• Away from direct spray from engine air intakes or water wash-down. • Don’t place a return air grille directly opposite the finned coil surface of an evaporator.

See Air Ducting - Ventilation, section “5) Return Grill Offset”.

Mounting the Classic unit: Orient the unit so the refrigerant, electrical connections and service ports are accessible. Use “L” brackets to bolt the unit down. Fasten the mounting base pan securely in such a way that the unit can be removed for future service if need be. Do not remove any covers, caps or fittings that may expose any wiring or refrigerant. Only remove these items when you are ready to complete the installation or for service purposes. Removal of any covers may result in damage to the electrical components. Removal of the caps or fittings may result in refrigerant loss.

Installation and Positioning of Seawater Pump1) Seawater cooling: The seawater system shall consist of a scoop-type thru-hull fitting, water shut-off valve or seacock, strainer, seawater pump, water hose and overboard discharge fitting. Water shut-off valve at thru-hull fitting is for safety and maintenance. If more than one Classic unit is using a single seawater pump, a water manifold and pump relay are also needed.

Install the pump/strainer assembly in such a manner that a natural gentle upwards slope exists from the sea-cock to the pump itself. See Figure 4.

Make sure that pump/strainer are accessible for service and maintenance.

ATTENTION It is strongly recommended to install air-bleeder systems both in the suction line as well as immediately after the discharge outlet of the pump. The advice is especially valid for pumps WB250/350/1000. The WB1500/2000 and Calpeda pumps 0.5HP to 1HP generally will not require a bleeder system to ensure proper operation.

It is strongly recommended to install a water scoop at the entry of the sea-cock and directed towards the bow of the boat so that at speed positive pressure builds up in the supply line to the seawater pump.

Figure 4 Self-priming Seawater Pump WB200

2) Seawater cooling exits: Provide for a separate seawater exit for each air conditioning unit installed even if only one pump provides cooling for all units. Introduce shut-off valves for each unit if 1 pump provides cooling for more than 1 air conditioning unit. This will allow easy priming of the circuit and also calibration of the seawater flow for each air conditioning unit in case of imbalance in the water tubing lengths.

3) Evaporator coils: The finned coils of the evaporators and/or air-handlers are fragile. If the fins are damaged during installation, take care to re-align them to ensure proper air-flow.

4) Air-ducts: Flexible air-ducts need to be of good quality with sufficiently strong steel or plastic reinforcement. Do not restrict air flow by bending the air-ducts too tightly or by accidental local deformation. Do not install air ducts of excessive lengths (> 2.5 m); the pressure loss and consequent reduction of air-flow will seriously diminish the efficiency of the installation.

Air Ducting - Ventilation1) Minimum Air Grill Sections: In order to obtain an acceptable noise level at max. blower speed certain requirements regarding grill and duct sections should be observed. Also, the size of the transition box behind the supply air grill is important. See Table 2 to select correct grill sections according to BTU rating.

2) Duct Type: To avoid accidental crushing, flexible air-ducts should be of high quality with sufficiently strong steel spiral reinforcement. Spiral type ducts should be extended to their maximum possible length to obtain max. interior smoothness. For very long duct sections preference should be given to rigid ducts (in PVC for example) which offer a far greater smoothness than flexible spiral type ducting and therefore will greatly reduce internal friction. For very short lengths non-insulated ducts may be used. Over greater lengths it is advisable to use insulted type ducts to avoid condensation on the outside of the air-ducts.

NOTE: For duct lengths over 1.80 m, it may be possible to use the nominal duct diameter (for example 100 mm - 6,000 BTU model), if instead of spiral type flexible ducts, rigid perfectly smooth interior ducts are used.


3) Blower Outlets: 90° turns with flexible ducts directly from blower outlets should be avoided at all costs as they introduce severe restrictions in the air flow. All WEBASTO blowers (except on 24,000 BTU models) can be rotated through 45° steps so as to obtain a straight-line outlet from the blower. See Figure 6 for approved installation.

Figure 6 Rotating Blower Outlet

4) Transition Boxes: Transition boxes behind supply air grills essentially serve the following purpose: Serve as an expansion volume for the air-flow to be reduced in velocity and therefore reduce air noise when crossing the outlet louvres. It follows therefore that the depth of the transition box is an important factor to allow dispersion of the air flow. The table (see Figure 7) gives the necessary information as to the minimum dimensions advisable for such transition boxes.

Figure 7 Transition Box Information

5) Return Grill Offset: It is best to avoid placing a return air grill directly opposite the finned coil surface of an air-handler. This will inevitably allow propagation of direct blower or compressor motor noise through the grill. Always try to offset the grill so the return air does not flow directly to the coil inlet. This will lower direct noise propagation significantly.

TROUBLESHOOTING Webasto BlueCool Classic Series AC Systems

23

TROUBLESHOOTING

Routine Checks When starting up an air conditioning unit it is advisable to carry out a certain number of routine checks to ensure proper functioning of the unit:

1. Always check (especially after a long absence) the functioning of the seawater cooling system. Immediately stop the system if no seawater comes out of the pump exit after compressor start up.

2. Periodically check the seawater strainer. Clean if necessary.

3. Periodically check the air filter in the return air grills. Clean if necessary.

4. Check condensation drain from the evaporator drain pan, take care to not damage the air-ducts. A damaged air-duct may stop air flow through the evaporator, freeze up the evaporator and subsequently damage the compressor.

Troubleshooting

CAUTION! Always use genuine Webasto service and replacement parts to ensure trouble-free operation of the AC system.

ATTENTION Advanced troubleshooting requires comprehensive knowledge about structure and theory of operation of the air conditioning components and should only be performed by authorized Webasto trained specialists.

1. No sign of life: check main electrical supply, fuses, etc.

2. The digital display shows 3 letters <AAA>. This means a persistent state of low voltage (less than 195 V AC for 230V units and 90V AC for 115V units). The system will restart as soon as the voltage level climbs above cut-out level and the system will then restart after a time-delay of 1 minute approx.

3. The compressor will start but no seawater circulation can be observed:

• Check sea-cock to seawater pump.

• Check seawater strainer.

• Check if pump rotates. If the pump does not turn with the compressor working, check power supply from the main control unit box to the pump.

4. Compressor and pump work but no correct operation in either cool or heat cycle:

• Check for proper air ventilation, blowers. If air flow completely stops with the compressor working, the evaporator coils may freeze up completely, obstructing all air circulation.

• During the heat cycle with too slow seawater circulation you may actually freeze up the seawater in the cupro-nickel condenser and completely block and damage the system.

• Check voltage level. Do not operate a system with a persistent voltage level below 195V AC for 230V units and 90V AC for 115V units.

• Check refrigerant charge if operation is still not satisfactory, after having checked all the above points.

5. The compressor works but is subject to intermittent stops without having attained the desired setpoint temperature. The HP and BP (if present) pressure safety switches stop the compressor because of abnormal working pressures either on the high or on the low side.

• Check for proper functioning of the cooling circuit.

• Check ventilator/blower system for obstructions.

• Check refrigerant charge (over-charge or insufficient charge level).

• Check for Error codes / interrupted system operation.

Webasto BlueCool Classic Series AC Systems TROUBLESHOOTING

6. The heat cycle takes very long to get started. Normal if the seawater temperature is very low. If seawater temperature drops below approx. 6 °C (43 °F) the heat cycle becomes much less effective and takes long to get properly started.

Visual Error Codes - Digital DisplayThe following malfunctions will be displayed directly on the digital display by a code and will be followed by a system halt. Whenever any of these codes appear the system is stopped for approx. 60 seconds and then a restart is attempted. If for more than 30 minutes the same malfunction occurs, the system will be stopped completely and the error code will become steady. No more restarts will be attempted and the user will have to re-set the system by pushing the <On/Off> switch or by temporarily cutting out the AC supply to the system

Code A01 to A08: Pressure safety cut-out of compressors 1 to 4.The HP and BP (if present) safety controls are directly controlled by the micro-processor including the time-delays for restart, etc. See note *) Standard TCC controller cards have only 1 outlet for 1 single compressor. However the embedded micro-processor program can operate up to 4 WBCC units from 1 single controller card. This special controller card can be obtained on special request but is not standard delivery.

ATTENTION *) Models WBCC5 to 12 do not have a low pressure safety switch (BP); therefore if you see a A01 warning on such

model, it can only be an electrical connection problem on the 3 pole HP/BP connector on the TCC controller card. Check that the connector is properly seated and that the BP strap is properly tightened.

If any of these error codes appear too frequently and no appropriate action can be taken with the available means on board, it is necessary to call a specialist.

Do not insist with manual restarts in such case as this may cause major damage to the principal components (compressors, pumps, etc.)

Webasto BlueCool Classic Series AC Systems CHOOSE THE RIGHT BLUECOOL

CHOOSE THE RIGHT BLUECOOL How to choose the right BlueCool air conditioner? Example: You own a yacht and would like to aircondition a room of 5 m (length) x 5 m (width) x 2 m (height).

Step 1

Determine the category of the cabin. We give an example for a cabin with an average glass area, for example a deck saloon.

Category 2

Step 2

Determine the net volume of the room (5m x 5m x 2m = 50 m3; subtract 20% for

furniture in the room; 50 m3 - 10 m3 = 40 m3; If you want to air condition the whole boat, please calculate the sum of your rooms).

40 m3

Step 3

Determine the climate region where you spend most of your time. For example the Mediterranean Sea is a “normal region” in the climate category.

Normal region

Step 4

Result: You need an air conditioning system with a 20,000 BTU cooling performance. 20,000 BTU

Step 5

Depending on the demands you can decide on a BlueCool Classic, Select or Premium with a cooling capacity of 20,000 BTU.
