9.2 Failsafe and Fault Handling Codes
When a fault is detected the Marine Climate System will display one of the
following Mnemonic fault codes:
"ASF": Indicates Air Sensor Fault.
"FIL": Indicates filter needs replacing (if this option is enabled).
"HPF": Indicates High Freon Pressure.
"LAC": Indicates Low AC voltage (if this option is enabled).
"LPF": Indicates Low Freon Pressure (Not applicable to MCS models).
"PLF": Indicates high water temperature in condensing coil (if this option
is enabled).
Note
I
"HPF" is not indicated and does not cause lockout in Heat Mode.
"LPF" has a 10 min shut down delay.
Possible Reason
Set point temperature is improp-
erly set: too low for cooling or too
high for heating.
Porthole or hatches open.
Seawater temperature too high
for cooling or to low for heating.
Improper air sensor location.
Cold supply air returning directly
to return air grille.
Troubleshooting
Solution
Raise or lower set point.
Close all port holes and hatches.
Seawater temperature will
directly affect the air conditioning
unit's efficiency.
This air conditioning unit can
effectively cool your boat in water
temperatures as low as 40 °F
(4.4 °C) and heat (if reverse cycle
option is installed) in water up to
90 °F (32.2 °C).
See corresponding section in
chapter "Control Panel Trouble-
shooting" on page 29.
Redirect supply air so that it is not
directed into the return air
stream.
