Use the LED3 display to confirm that the settings are properly made.
The settings will need to be set again when the control board is replaced. Write down the settings on the electrical wiring drawing label.
2) A: OC: Only the switch on OC needs to be set for the setting to be effective.
B: OC: The switches on both the OC and OS need to be set to the same seeing for the setting to be effective.
C: OC: The switches on both the OC and OS need to be set.
D: OC: The switch on either the OC or OS needs to be set.

5) Unless otherwise specified, leave the switch to OFF where indicated by "-" or where the cells are blank, which may be set to OFF for a reason.
6) The settings that are configured with SW4 (SW6-10: ON) will automatically be stored on the indoor units that support the new function*. The stored
settings will automatically be restored when the outdoor unit control board is replaced.
If none of the connected indoor units supports the new function, no configuration information will be saved. If this is the case, manually record the
settings configuration on the control box panel.
*The new function is supported on most units that are manufactured in April of 2012 and later. Depending on the model, this function may be added
on later date. Ask your dealer for further details.
