The following table describes some common
occurrences that are not a result of defective
workmanship or materials.
Problem
Possible Causes
Recommended Solution
The system does
not power up.
The air conditioning unit circuit breaker is off.
Turn on the air conditioning unit circuit breaker at the ship’s panel.
The display is not turned on.
Turn on the display.
The terminal strip is miswired.
Check the wiring diagram and correct if necessary.
The input-line voltage is insufficient. 7
• Check the power source (shore/generator) for proper voltage.
• Check the wiring and terminals for proper sizes and connections.
• Verify with a voltmeter that the power at the unit is the same as the
power source.
An electrical component has failed.
A technician should inspect the display, cable, and circuit board. Look for
a red light on the circuit board.
The system runs
continuously.
The unit is not able to reach the set point.
Close all the port holes and hatches. Adjust the set point so it is not too
low for cooling or too high for heating.
The seawater temperature is too high for
cooling or too low for heating.
Seawater temperature will directly affect the air conditioning unit’s
efficiency. This air conditioning unit can effectively cool your boat in water
temperatures up to 90 °F (32 °C) and heat (if reverse-cycle option is
installed) in water as low as 40 °F (4 °C).
The optional inside air temperature sensor is
not located properly.
• Verify the display location with the criteria found in the installation
section of this manual.
• Install an optional inside air temperature sensor if necessary. If an
optional inside air temperature sensor is already installed in the air
stream, ensure it does not touch anything warm (like the condenser
coil).
The de-icing feature is not enabled.
Enable de-icing in the parameters. If ice still forms immediately, revisit the
above possible causes.
I
Ice on a fan coil can be removed quickly by running the unit in HEAT
mode.
There is a lack of
airflow.
The airflow is blocked or restricted.
• Remove any obstructions in the return-air stream.
• Clean the return-air filter and grille.
• Check for crushed or restricted ducting. Ducting must be as straight,
smooth, and taut as possible.
The fan speed is set to manual low.
• If the fan speed is set to manual low, raise the speed to a higher setting
or set to automatic mode.
• Or, increase the minimum low speed in the program parameters.
The fan coil may be iced.
Refer to “The fan coil is iced.” in this table.
The fan coil is iced. The humidity level is set too high.
Close the hatches and doors.
The supply air is short-cycling.
• Redirect the supply air so that is not blowing in or near the return-air
stream.
• Seal any air leaks on the duct.
The airflow is blocked or restricted
Refer to “There is a lack of airflow.”in this table.
The fan runs too slow.
Set the fan speed to automatic mode or increase the manual fan speed.
Or, increase the minimum low speed in the program parameters.
The system runs continuously.
Close hatches and doors, raise set point, turn on de-icing.
