function of SW4, write down the SW4 (982) setting on the control board panel, and manually reset the setting after the control board is replaced.
4) 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.

settings will automatically be restored when the outdoor unit control board is replaced. Not applicable to SW4 (982).
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 December of 2012 and later. Depending on the model, this function may be
added on later date. Ask your dealer for further details.
