The other cases
Indoor unit does not operate. (different operating models in multi system)
• When you try to run two indoor units simultaneously, one for cooling and the other for heating, the unit which transmits signal
to the outdoor unit first decides the operation mode.
• When the above situation occurs, set all the indoor units to the same mode, turn OFF the indoor units, then turn them back
ON.
• Though the top of the indoor unit sometimes gets warm, this does not mean malfunction.
The reason is that the refrigerant gas continuously flows into the indoor unit even while it is not operating.
Check of bus-bar voltage
•Check the voltage of power supply.
