While simultaneously operating two indoor units or more, make sure the operation modes will
not conflict with each other. The heat mode claims precedence over all other modes.
For example: If the unit intially started operates under cool(or fan) mode, the other units can
operate under any mode except heat. If one of the unit selects heat mode, the other operating
units will stop operation and diplay P5 (For the units with display window only) or the Auto and
Operation indication light flash rapidly, the Defrost indication light turn off, the Timer indication
light remain on(For the units without display window), or the Defrost and Alarm indication light(
if applicable) illuminate, the Operation indication light flashes rapidly and the Timer indication
light turns off ( For the Floor and standing type).
If the unit
intially started operates under heat mode, the other units can operate under heat mode only.
