NOTICE:
● Adequate monitoring and control may not be assumed upon occurrence of device failure. It is strongly
recommended to prepare alternate plan (as to use Remote Control Switch (RCS) 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.
● VRF Central Touchscreen Controller, Extension 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 VRF Central Touchscreen
Controller.
Correct operation may not be expected due to unnecessary clock setting change on VRF Central
Touchscreen Controller.
● 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.
Terms De fi nitions
RC-less, (Remote
Controller-less) unit
This term indicates indoor unit without remote controller connected to it. This does not
include instances where multiple indoor units are connected or set to be controlled and
monitored by a single remote controller.
Facility unit The units are monitored or controlled by this software through external input/output(s).
PIO
(dedicated extension
pulse input/output
device)
In this document, PIO refers to programmable logic controller with 128 input/output
each manufactured by Industrial Equipment Systems Co. Ltd.
VRF Central Touchscreen Controller (CCXL01) and VRF Central Touchscreen
Controller Adapter (CCXLA01) can monitor/control 2 PIO devices respectively.
● To connect RC-less indoor units to the system, the indoor
units need to support dual setpoint.
Maximum external input 128
Maximum external output 128
