7.5 Automated Factory Self Test Program
The Marine Climate System software provides a self test program to facilitate
factory testing of the entire air conditioning system. Once the self test pro-
gram is activated, the test cycle will continue until the AC power is interrupted
or the Power Button is pressed once which returns the system to the Off
Mode.
➤ Activate the self test program by pressing the Power Button while turning
on the AC power.
➤ Release the Power Button while the display indicates “888” and all LEDs
are lit.
✓ The Marine Climate System is now in the self test program.
✓ “tSt” appears in the display while in the self test program.
Once activated the self test software will continuously execute the following
procedure:

Turn on in the Heat Mode and supply heating for 10 min.
 Stop heating and run the fan only for 5 min.
 Switch to Cool Mode and continue cooling for 10 min.
 Stop cooling and run the fan only for 5 min.
 Return to step one and continue until interrupted.
The self test program will continue until the power is interrupted or the test is
halted by pressing the Power Button once.
