MCS6, MCS12, MCS16 Programming
P-5: Temperature Calibration
Use this feature to calibrate the ambient sensor.
➤ Select P-5.
✓ The ambient temperature appears in the display.
➤ Use the Up and Down Buttons to set the correct reading.
✓ The temperature in the display will increase or decrease as required.
P-6: Failsafe Level
There are four failsafe levels (see "Failsafe and Fault Handling Codes" on
page 26).
P-7: Low AC Voltage Shutdown
Use this feature to shut down the unit if the voltage drops to a dangerously
low level.
By default it is off, but it can be set from 175 – 205. This feature works imme-
diately at start up, but while running will require a 5 min delay before display-
ing a fault to prevent nuisances.
The fault code is "LAC".
P-8: De-Icing Cycle
The Marine Climate System is equipped with a de-icing cycle to prevent ice
build up on the evaporator coil during extended periods of cooling operation.
Installation variables such as grille sizes, length of ducting, insulation R fac-
tors and ambient temperatures determine the cooling run time required to
achieve set point. Customer usage may substantially increase run times by
operating the system with the hatches and doors open.
Programming an unrealistic set point (e.g. 65 °F/18.3 °C) and leaving the
salon door open will usually cause the evaporator to ice up on warm humid
days.
De-icing is accomplished by using an algorithm that closely monitors the
room air temperature in repeating 10 min intervals during a cooling cycle.
