6-2 Night Mode (Silent Mode) Schedule 
Click on [Function2]-[Night Mode Schedule] in the menu to open the night mode schedule screen and make 
necessary settings to switch the outdoor unit operation mode to the night mode (low-noise operation), and set 
the night mode time interval. 
Use this mode when low-noise operation of the outdoor unit is preferable during night. 
Note: If PAC-YG50ECA Expansion Controllers are connected, Expansion Controller system selection buttons will appear. Select 
the desired Expansion Controller (EC1, EC2, or EC3), and make the settings for each system. Make the settings with the 
Expansion Controllers properly connected. 
Note: Make this setting only when all the units operate normally. When connection error occurs at the indoor or the outdoor unit, 
night mode target units may not be displayed normally. 
Note: The noise level to be reduced varies depending on the unit model. 
Note: If the user logs in as a building manager, the operations may be prohibited.   
Note: When connecting AG-150A controllers by connecting an Expansion Controller to the system, night-mode settings should be 
made only on one of the AG-150A controllers. 
(1) Set the time interval in [Night mode start time] and [Night mode end time]. 
Note: When the starting time and the ending time is the same, night mode operation will always be performed. 
(2) Select the outdoor unit, which performs night mode operation from [Target outdoor units]. 
Note: M-NET address numbers for each outdoor unit are displayed in the target unit field.
