(including operating mode, temperature setting, and remote controller permit/prohibit setting)
• Alarm history and maintenance history
When the power returns, the operation of each group will follow the closest schedule setting made
before the power returned. In case there are no settings of run/stop, operating mode, prohibiting
remote controller operation, temperature setting, energy saving and silent mode etc. in the closest
schedule setting, it will follow the second closest schedule setting made.
In case there are no schedule settings on that day, this central control will not send any operation
signal to each group.
You do not need to reset the clock after a power outage.
Using USB Memory

• Be sure to use the bundled USB memory.

• Do not operate while the display light of the USB memory is blinking fast.
You may perform your operations or remove the USB memory only when the display light is
blinking slowly.
If the USB memory you use does not have a blinking light, please wait for a moment after each
operation.
Remove the USB memory only after all operations have been completed.
Important!!
Be sure to use the bundled USB memory device. (The central control does not recognize
commercially available USB memory devices and cannot transfer data to them.)
