Problem Possible cause Suggested remedy
The circuit breaker for the air conditioner is off.
Turn on the circuit breaker at the vessel's panel.
The power button is off on the display.
Turn on the power button on the display.
The voltage on the power supply cable is not high enough.
1. Verify the voltage on the power supply cable.
2. Check the wiring and terminals for proper sizes and con-
nections. Refer to the installation manual that came with
the air conditioner.
3. Use a voltmeter to verify that the power is the same at the
air conditioner and at the power source.
The system does not power up.
An electrical part has failed.
Contact a qualified service technician.
The system encountered a hard fault.
1. Check the fault history. Refer to Troubleshoot on page8.
2. Follow the corresponding troubleshooting steps in this
section.
The power source has lost power.
Verify that the power source is supplying power.
The system shuts down.
An electrical part has failed.
Contact a qualified service technician.
There is a power-related issue with the display, such as a pow-
er interruption, voltage frequency fluctuation, electromagnetic
interference from other equipment, or a similar issue.
1. Turn off or move any high-power electronics near the dis-
play.
2. Switch the existing display cable for a shielded cable.
3. If the problem persists, contact a qualified service techni-
cian.
The system does not respond to changes entered on the dis-
play.
The display and the air conditioner unit are not compatible.
Verify that the display being used is compatible with the air
conditioner.
The display does not show the correct room temperature. The return air sensor is in a position that does not accurately
reflect the cabin temperature.
1. Reposition the return air sensor to a better location, if
possible.
2. On the Parameters menu, use the Inside Temp Calibrate
feature to calibrate the air sensor.
The temperature of the seawater is too high.
Seawater temperature directly affects the unit's efficiency.
For optimal cooling, the water temperature must be less than
95 °F (35 °C).
The water flow is inadequate.
Verify that there are no obstructions in the water flow.
The system has lost refrigerant.
Contact a qualified service technician.
The system is not blowing cold air.
The mode on the display is not set to Cool.
Change the mode to Cool.
The temperature of the seawater is too low.
Seawater temperature directly affects the unit's efficiency. For
the unit to heat (if the reverse-cycle option is available), the wa-
ter temperature must be 40 °F (4.44 °C) or higher.
The reversing valve is stuck.
1. Lightly press on the valve with a rubber mallet while the
system is in Heat mode.
2. If the problem persists, contact a qualified service techni-
cian.
The auxiliary electric heater is enabled but not connected.
1. On the Parameters menu, set Aux Elec Heat to Off.
2. Verify that the breaker for the auxiliary heater is in the on
position.
The mode is not set to Heat on the display.
Change the mode to Heat.
The system is not blowing hot air.
The system has lost refrigerant.
Contact a qualified service technician.
The airflow is blocked or restricted.
1. Remove any obstructions in the return air stream.
2. Clean the return air filter and grille.
3. Check for crushed or restricted ducting.
The ducting must be as straight, smooth, and firmly sup-
ported as possible.
There is not enough airflow in the system.
The system is running in limit mode to pay for abnormal oper-
ating conditions caused by environmental factors such as sea-
water temperature, load, etc.
On the Troubleshoot menu, check System Status for the op-
erating mode. If the system cannot resume normal operation
within an hour, a Limit Mode alarm will be sent to the display
until normal operation can be resumed.
The compressor is not stopping. The variable speed compressor technology slows down, but
does not stop unless the temperature set point is exceeded by
1 °F (0.6 °C).
Adjust the temperature set point or use the power button on
the display to manually turn off the system.
