: Mixed operation Error

Mixed operation error is not due to a product problem but is displayed when the operational mode input in an indoor unit is different
from current operational status (other indoor unit's operational mode).
Check the operational mode of outdoor unit or other indoor unit then re-enter or stop the operational mode of the relevant unit.
If it is necessary to apply a different operational mode to an indoor unit from others, please stop other indoor units then operate the
indoor unit.
