TROUBLESHOOTING

Table 5

Failure
code

Description

Possible cause

Solution

<AAA> Low Voltage

Low voltage cut-out. Power
supply was over 5 sec lower than
controller setting. Probably
caused by long length power
supply cable or overload.

Check setting, default 195 V.
Don't set below 195 V to avoid
damages to the compressor or to
expire warranty.
Improve power supply.

<A01>

Low pressure cut-out
compressor 1
(Classic > 20,000
BTU)

Defective pressure sensor or
open/short circuit.

Check wiring or replace pressure
sensor on Schrader valve.

COOLING MODE:
Insufficient air flow.

Check air flow.

T evaporator in/out minimum

4K.

HEATING MODE:
Insufficient seawater flow or
seawater too cold (temperature
below 6 °C or 43 °F).
Blocked sea-water strainer or not
primed.

Check discharge water volume.
V= 8 l/min
(or > 30,000 BTU V= 18 l/min).

T in/out minimum 4K.

When T seawater < 4 °C:
preheating necessary.
Clean strainer and bleed seawater
circuit.

Lack of refrigerant.

Refrigerant leak check.

<A02>

High pressure cut-out
compressor 1

Defective pressure sensor or
open/short circuit.

Check sensor and wiring. Replace
sensor on Schrader if necessary.

COOLING MODE:
Insufficient seawater cooling.
Blocked seawater strainer or not
primed.

Check discharge water volume.
V= 8 l/min
(or > 30,000 BTU V= 18 l/min).
Clean strainer and bleed sea-
water circuit.

HEATING MODE:
Insufficient air flow.

Check air-flow.

T evaporator in/out minimum

4K.

Not used for BlueCool Classic units.

<A09>

Cabin temperature
sensor failure

Broken external temperature
sensor, open/short circuit, not
present or programmed wrong.

Replace sensor or controller.

<A10>

Evaporator
temperature sensor
failure.

Defective evaporator sensor or
open/short circuit.

Check wiring or replace sensor.
Water infiltration (condense) can
cause a read-out deviation or
erratic functioning before an error
code occurred.

<CA11> All compressors

manually off.

Compressor(s) programmed not
active in controller setting.

Check settings. At least one
compressor should be
programmed active.
C01=ON

C00=OFF

<bA11> Fan standby.

Blower operation from TCC card
impossible.
Discharge temperature higher
than set point on cooling or
lower on heating.

Run compressor/unit for a certain
time to reach required discharge
temperature.
Blower fan will start and blinking
error code bA11 will disappear
automatically.
