CAUTION
The multi-system air conditioner can not be in different operating modes at the same time, such as one
unit being in the “COOL” mode and one unit being in the “HEAT” mode.
When conducting different operations, the “HEAT” mode will be given priority. The indoor unit which
operates in “COOL” or “FAN” mode will stop and display “P5”.
