● OPERATING INSTRUCTIONS ●
AUTO mode (Auto change over)
The unit selects the operation mode according to the difference between the
room temperature and the set temperature. During AUTO mode, the unit

away from the set temperature for more than 15 minutes.
Note:
During multi system operation, the unit may not be able to switch opera-
tion mode between COOL and HEAT. In this case, the indoor unit becomes
standby mode.
Auto Mode is not recommended if this indoor unit is connected to a MXZ type
outdoor unit.
