(*1) RC-less indoor unit indicates the indoor unit without remote controller.
This does not include instances where multiple indoor units are connected or set to be controlled and monitored
by a single remote controller.
NOTICE:
● Adequate monitoring and control may not be assumed upon occurrence of device failure. It is strongly
recommended to prepare alternate plan (such as to use Remote Control Switch to control/monitor air
conditioners) for such cases.
● Conduct test run on all indoor units to ensure system is operating correctly.
● Upon recovery, make change or control again as necessary if air conditioning system is not working as
expected.
● Central Station EX, Central Station EX Adapter and their peripherals are assumed to be always ON.
Energy calculation, usage history and other history records for period within which any of the device was
turned OFF may not be available.
● Controlling and monitoring on the system are all based on the clock on Central Station EX.
Correct operation may not be expected due to unnecessary clock setting change on Central Station EX .
● Use keyboard exclusively for inputting character strings.
● 60, 61, 64 and 65 alarm indicates communication failure between air conditioners and this system.
Hence each value shown on screen may not be of actual value.
● The screen-shot image in this manual may differ from the actual controller image.
● While you are reading pulse via external input, pulse count is not accumulated when power is cut or
checking connection. This may affect to usage accumulation and calculation. This important item needs to
be well discussed with customer prior to system launch.
