UNITA' CENTRALE
I problemi dell'Unità Centrale CWS possono derivare da:

• Mancanza di circolazione dell'acqua di raffreddamento (circuito acqua mare);  questo problema si può verificare controllando lo scarico fuori bordo.  Il funzionamento senza raffreddamento può, a lungo , causare altri danni all'impianto. In caso di dubbio far verificare il circuito acqua mare tenendo spento l'impianto di condizionamento.
• Problemi di alimentazione elettrica insufficiente (voltaggio insufficiente). L'alimentazione insufficiente può causare danni alle parti elettriche ed anche al compressore se si insiste a cercare di farlo funzionare.

FAN COIL
La ventola del fan coil non funziona: verificare per prima cosa che il pannello di controllo sia adeguatamente impostato alla modalità   desiderata ("Cool" in estate e "Heat" in inverno) e che il termostato sia ruotato completamente verso "18" in estate o verso "24" in inverno.
Quindi controllare le spine di collegamento. Se sono in ordine, controllare la tensione ai terminali delle spine dopo aver selezionato la velocità   massima.
La tensione fra i fili nero e blu deve essere 230V. Se la tensione è giusta, il motore della ventola è difettoso e deve essere sostituito. Fornire al servizio assistenza ogni dettaglio sul fan coil e sul motore al fine di ottenere il ricambio adeguato. Tener conto che il motore del fan coil deve funzionare con il suo condensatore di funzionamento specificato installato nella scatola di controllo.
Se non vi è tensione, controllare il commutatore e il termostato sul pannello di controllo.

First Level alarms:

The controller stops the compressor and starts an auto-reset timer in case of:

• Refrigerant Low Pressure (LP)
• Refrigerant High pressure (HP)
• Low fresh water flow (Fresh Water Flow)
• Low fresh water temperature (Antifreeze)

Pressing  ENTER additional information on alarms are displayed:

 
After 3 cut outs made by the “first level alarms” (3 is the default number) the system goes in the Master Alarm mode which requires the manual reset.

Second Level alarm: Master ALARM ( manual reset)


The control system is reset by pressing ENTER and goes back to the first menu page with the system OFF.
From this point it is possible to restart the system once the origin of the alarm is cleared.
Note: the system  goes in Master Alarm also in case of disconnected or faulty fresh water temperature probe.


CENTRAL UNIT PROBLEMS -  RED LED  “GENERAL ALARM”:
All the alarms are triggering the red LED  “General Alarm” .



Alarms:
Fresh Water Flow: it means that the fresh water flow in the module is to low. This causes the flow meter stops the compressor. Running the compressor in this situation is very dangerous and  high care must be taken to find the cause of this alarm. Check that:

• The fresh water pressure stays between 1 e 2 bar
• The fresh water pump runs regularly and quietly.
• There is no air inside the fresh water circuit. The pump must runs very quietly.
• If the system is equipped with a spare pump, select this pump and make the necessary changes in the water circuit.

LP : low refrigerant pressure: this module has a problem and needs service. Exclude this module and call the authorized CLIMMA service.
HP:  high pressure: this module has reached the high pressure cut out.
In COOL mode: Check the sea water circuit (inlet, strainer and oulet). If the system is equipped with a spare sea water pump, turn the switch to this option, make the necessary changes on the sea water circuit and run the system wth the spare pump. This alarm is however stopping the the sea water pump and in consequence, all the compressors.
In HEAT mode: (Reverse cycle): check the functioning of the fresh water pump.

• Antifreeze Alarm : The fresh water temperature has reached a lower minimum limit with the risk of freezing. Check the fresh water circulation (in cool mode) or the sea water circulation (heat mode), see next point.
  Note: Check always that the fresh water circuit has an antifreeze solution.
• The system doesn't heat enough: All the units supplied with reverse cycle can run with seawater temperature above 10° C, which is common in the Mediterranean Sea. If the sea water temperature falls below 10° C the system should never be run as the sea water heat exchangers could be damaged by freezing. .

FANCOILS' PROBLEMS
The blower  doesn't run: make sure first that the control panel is properly set to the desired "Mode" function (cool in summer and heat in winter) and that the thermostat is turned completely to " +15 " for summer operation or " +28 " for winter operation.
Then check the connections. If they are OK, then test the voltage at the blower terminals  with the max speed  selected. The voltage must be 230V. If the voltage is correct, then the fan motor is defective and must be replaced. Give the fan coil and if possible the motor details to the service in order to get the correct spare. Be aware that the fan coil motor must run with its specified run capacitor, which is installed on its cable.
If there is no voltage then check the change over switch and the thermostat on the control panel.

CENTRAL UNIT PROBLEMS
Red alarm light (FL) : this means that the fresh water flow in the circuit is lower than the minimum accepted. This has caused the safety flow switch to cut the unit off. This situation could be very dangerous for the unit and extreme care must be taken in investigating the reason of the cut off.

Check that:

• The pressure in the fresh water circuit is between 1 and 2 bars
• The fresh water pump circuit breaker is engaged and OK and the fresh water pump is correctly turning.
• There is no air in the fresh water circuit. The fresh water pump shouldn't be noisy.
• If the system is equipped with a spare pump, make the necessary changes to the fresh water circuit, turn the pump change over switch to number "2",and run the system with the spare pump.

Compressor alarms:

• Yellow lamp → low pressure: the corresponding module has been working with a pressure too low. Call service and turn this compressor switch to 0.
• Red lamp → high pressure: the corresponding module has been working with a pressure too high, probably due to lack of cooling water.

In Summer operation: check the sea water circuit (intake, strainer and outlet) If the system is equipped with a spare sea water pump, turn the pump switch to "2" and make the necessary changes in the sea water circuit and run the system with the pump N.2. This alarm stops the sea water pump and consequently all the compressors will go off until the Reset procedure is made.
In winter operation (reverse cycle): check the fresh water circuit as this pump is now cooling the condenser.

• Both the yellow and red lamps contemporary on →  it means an intervention of the compressor internal overload safety. Call service and turn this compressor switch to 0.

• The system doesn't heat enough → All the units supplied with reverse cycle can run with seawater temperature above 10° C, which is common in the Mediterranean Sea.

If the sea water temperature falls below 10° C the system should never be run as the sea water heat exchangers could be damaged by freezing.

FAN COILS PROBLEMS
The blower doesn't run → make sure first that the control panel is properly set to the desired "Mode" function (cool in summer and heat in winter) and that the thermostat is turned completely to " +15 " for summer operation or " +28 " for winter operation.
Then check the connections. If they are OK, then test the voltage at the blower terminals with the max speed selected. The voltage must be 230V. If the voltage is correct, then the fan motor is defective and must be replaced. Give the fan coil and if
possible the motor details to the service in order to get the correct spare. Be aware that the fan coil motor must run with its specified run capacitor, which is installed on its cable.
If there is no voltage then check the change over switch and the thermostat on the control panel.

SAFETY BLOCK DIAGRAM

• FLOW Alarm → Safety PCB → Carel step regulator Offset → Compressors stops
• HP alarm compressor #1 → Safety PCB:
  → Carel step regulator offset
  → Compressor #1 stops
  → Sea water pump stops (Cycle)
  → All compressors stop

• LP alarm compressor #1 →  Safety PCB → Compressor #1 stops

IF NOTHING WORKS
See if power is supplied to terminals "L" and "N" in the AC Power terminal strip.

• IF NO POWER → Probably there is a problem and power is not supplied.  Restore main power.
• IF POWER →  Fuse F1 can be blown. Keep in mind that "F1" powers the: fan, sea water pump, control panel, power relay NOT THE COMPRESSOR. Check the electrical box for the presence of water or moisture.  Disconnect the different loads so as to identify the cause of the failure.  Check/replace fuse "F1" of electrical box.

IF FAN IS NOT RUNNING
Check the connecting plug between the fan and the electric box, it may be defective, reconnect the wiring.

IF SUMMER  CYCLE

• The fan will not run → Check the connecting plug between the fan and the electric box, it can be defective. Reset the connection.
• Compressor will not run, but  fan and sea water pump run. → The thermostat can be set to high, turn the thermostat knob counterclockwise all the way, towards "-"

If the compressor still won’t work, the power relay of the compressor can be blown,  replace compressor power relay K1 if possible with a static relay.
If the compressor still won’t work,  the compressor may be broken. Fit a new compressor.

• The air-conditioner works but the temperature in the cabin does not decrease
• The compressor runs for a while, stops and then restarts of its own accord, even with the thermostat set on max. → Make sure that the thermostat sensor is located on the air intake side. Check seawater circulation. Thermostat sensor not correctly installed. Seawater is not circulating and this triggers the  high pressure switch (HP). Install thermostat sensor correctly Clean water filter, check piping and reset seawater circulation.
• Fan emits little air and evaporator is covered with ice →  Air circulation is insufficient resulting in the formation of ice that obstructs the flow of air. Clean or replace the air filter (see 3.1). If problem persists check air flow.

IF WINTER CYCLE

• The air-conditioner works but the temperature in the cabin does not increase → the thermostat may be too low, adjust thermostat settings.
• Compressor will not run, but  fan and sea water pump run. → The thermostat can be set to low, turn the thermostat knob clockwise all the way, towards "+".  If the compressor still won’t work, the power relay of the compressor can be blown,  replace compressor power relay K1 if possible with a static relay. If the compressor still won’t work,  the compressor may be broken. Fit a new compressor.
• The compressor runs for a while, stops and then restarts of its own accord, even with the thermostat set on max. → Make sure that the thermostat sensor is located on the air intake side. Check seawater circulation. Thermostat sensor not correctly installed. Seawater is not circulating and this triggers the  high pressure switch (HP). Install thermostat sensor correctly Clean water filter, check piping and reset seawater circulation.
• IF EH VERSION: The electric resistor warms up for a few minutes, then turns off and cold air comes outs → Make sure that the thermostat sensor is located on the air intake side, it can be not proberly installed. If the sensor is installed properly, then the air circulation may not be sufficient and has triggered the resistor protection.  Clean or replace the air filter (see 3.1). If problem persists check air flow.

When the display is off
Check the powerboard supply to the unit. Check the good functioning of the connection cable plug both from the powerboard side and from the panel side.
If the powerboard is correctly supplied (the warning lights are blinking) and the cable is unblemished and correctly inserted, call the assistance service for a more precise control.

Display shows [nPr]
The powerboard has not correctly been set out or the CHANGE OVER is not connected. Set out the dip switch.

Display shows [NA]
It means that the demanded function is not available for the set out functioning. Check that parameters are correct.

The lines under pressure visibly vibrate

• Dirty water filters → clean and replace filters
• One or more nozzles clogged → disassemble and clean the nozzles
• Air in the pipes → Open the end of line valve to expel the air from the pipe

The ECO unit is pumping but no water comes out of the high pressure line

• Air in the water circuit → expel the air from the line
• end of line open or leakage in the circuit → find and repair the leakage
• ampering with the flow adjustment knob or the by-pass in the machine head → Ask for the intervention of the supplier or authorized technician
• Several nozzles clogged → switch off the misting unit, clean or replace clogged nozzles

The ECO does not activate when the start button is pressed

• no electrical supply → check the electrical connection
• the residual current device has triggered → lift the switch and start the unit
• incorrect electrical connections or cables of unsuitable size → check cable diameter, extension cable length and electrical connections
• no water (green indicator light on)
  
  • open the water network tap
  • check if the filter is clean and if water flows freely through it
  • make sure the water flow is correct

NOTE: Always wait one minute for the system to start. There is up to one minute delay between the power ON and the compressor starting. Allow enough time.

THE BOX IS TOO COLD OR THE COMPRESSOR RUNS CONTINUOSLY
Turn the thermostat clockwise towards 1 . If the box is still too cold with thermostat set at 1 , then stop the compressor, putting the thermostat to 0 or switching off the fridge switch. Use this switch to make run the compressor for 15 minutes every 1 – 3 hours to keep the box at the normal temperature (+2 / -6 ). The unit must be checked by a Frigoboat authorized Service Center.

THE BOX IS NOT COLD ENOUGH ALTHOUGH THE COMPRESSOR RUNS NORMALLY
Remove any warm food from the box and let it cool down to ambient temperature before storing it again.
The door must be perfectly closed and the door gaskets must fit perfectly. Nothing must prevent the door gasket to seal.
Check that there are no obstructions in the compressor air intake and outlet and the condenser is clean.
When the compressor is running, the fan should run in air-cooled models and the pump should run and the water flow in W models. Otherwise it is necessary to clean the filter.

THE COMPRESSOR STARTS BUT IT STOPS ALMOST IMMEDIATELY
Check the battery charge. If necessary, charge the battery.
Check that all the connections and the fuse of the battery supply to the Frigomatic are well tightened and not corroded.
In winter the compressor temperature should be above 0 C.
Disconnect the F terminal from the electronic control. If the compressor runs correctly, check the fan, the pump or the pump relay as the amperage is too high. As soon as you can, the unit should be checked by a Frigoboat authorized Assistance Center.

THE COMPRESSOR DOESN'T START
There is a delay between the power ON and the compressor starting. Wait one minute.
On the electronic control check that the + and - voltage is 12 V (24 V) and the thermostat has been set on 7.

First, always wait 1 minute: There is up to 1 minutes delay between power ON and the compressor starting.  Allow enough time.

LOW VOLTAGE CUT OUT
The cut out operates when the voltage entering the controller falls below 10.4V (21V). In case of doubt charge the battery. Then check the voltage during compressor start as wiring faults can cause an artificial voltage drop on start up amperage.

THE BOX IS TOO COLD OR THE COMPRESSOR RUNS CONTINOUSLY
Turn the thermostat clockwise towards '1'. If the box still too cold with thermostat set at '1' then stop the compressor putting the thermostat to '0' or switching off the fridge switch. Use this switch to run the compressor 15 minutes every 1 - 3 hours to keep the box at the normal temperature (+2°C to +6°C) - (36°F / 43°F).
Have the unit checked by an authorized Frigoboat Service.

THE BOX IS NOT COLD ENOUGH AND THE COMPRESSOR RUNS NORMALLY
Remove any warm food from the box and let the box cool down to ambient temperature before storing it again.
Check the door is perfectly closed and the door gasket fits perfectly and nothing prevents the door gasket to seal.
Check that the compressor air intake and outlet are clear of obstructions and the condenser is clean.
When the compressor is running if the model is air cooled the fan should run. If the model is water cooled with pump, then the the pump should run and water should flow through the circuit.

THE COMPRESSOR STARTS BUT IT STOPS ALMOST IMMEDIATELY
Check that the voltage is correct, if in doubt charge the battery.
Check that all of the connections and the fuse in the supply from the battery are well tightened and not corroded.
In winter the compressor temperature should be above 0°C.
Disconnect terminal “F” from the Electronic Controller. If the compressor then runs correctly, check the fan or pump or pump relay as the amperage is to high. As soon as you can, get an authorized Frigoboat Service agent to check the unit.

THE COMPRESSOR DOES NOT START
As above, there is a delay between the power on and the compressor start. Allow at least 1 minute.
On the Electronic Controller check that:
- The voltage between “+ “ and “- “ is 12V (24 V) on compressor start
- The thermostat is set on “7”
Bridge terminal “T” and “C” (thermostat). If the compressor then starts, leave the bridge.
Run and stop the system using the external (panel) switch (See 9.1.1). Replace the thermostat as soon as you can since it is broken. If the compressor doesn’t start, contact an authorized Frigoboat Service.
