- 1 cool dry and fan mode may be used at the same time auto mode automatically selects cool mode or heat mode based on the room temperature therefore auto mode is available when selecting the same operation mode as that of the room with the first unit to be turned on 162
- However outdoor unit quiet operation display remains on the remote controller for other rooms we recommend you release all rooms using their remote controllers 162
- Night quiet mode available only for cooling operation 162
- Night quiet mode reduces slightly the cooling efficiency of the unit 162
- Night quiet mode reduces the operation noise of the outdoor unit during the night time hours to prevent annoyance to neighbors 162
- Night quiet mode requires initial programming during installation please consult your retailer or dealer for assistance 162
- Normally the operation mode in the room where the unit is first run is given priority but the following situations are exceptions so please keep this in mind if the operation mode of the first room is fan mode then using heating mode in any room after this will give priority to heating in this situation the air conditioner running in fan mode will go on standby and the operation lamp will flash 162

- The cooling heating mode lock requires initial programming during installation please consult your retailer or dealer for assistance the cooling heating mode lock sets the unit forcibly to either cooling or heating mode this function is convenient when you wish to set all indoor units connected to the multi system to the same operation mode 162
- The night quiet mode is activated when the temperature drops 5 c or more below the highest temperature recorded that day therefore when the temperature difference is less than 5 c this function will not be activated 162
- This system has one outdoor unit connected to multiple indoor units 162
- What is a multi system 162
- When clearing outdoor unit quiet operation clear one of the operating indoor units using their remote controller 162
- When more than one indoor unit is operating priority is given to the first unit that was turned on in this case set the units that are turned on later to the same operation mode 1 as the first unit otherwise they will enter the standby mode and the operation lamp will flash this does not indicate malfunction 162
