FEATURES OF CONTROL SYSTEM

SIMPLE WIRING SYSTEM
„ „
● 1 transmission line can interlink all equipment regardless refrigerant circuit.
● Non polar 2-conductor transmission cable.
● Central control equipment can be connected anywhere on the transmission line, with no need
to bring from the outdoor unit.
„ - Making up the network system easily.
„ - Saving the total wiring length.
„ - Preventing incorrect connection.
„ - Saving installation time.
ADOPTION TO LARGE SCALE BUILDINGS
„ „
● 1 VRF network system allows to form large scale application as follows:
„ - Total transmission wiring length can be extended up to 3,600 m with signal amplifier unit.
„ - Indoor units can be connected up to 400.
„ - Outdoor units can be connected up to 100.
„ - Touch Panel Controller can be covered to control whole equipment centrally.
„ - By using multiple Touch Panel Controllers, control by individual zone or floor is possible
for convenient usage in various building applications.
„ - By adopting a separate interface, it is possible to connect other products and systems by
FUJITSU GENERAL such as Single type models (excluding some models), J series or
Multi air conditioner for buildings (e.g. Big multi). (Refer to 3-1. NETWORK CONVERTOR.)
● System Controller allows to control up to 4 VRF network systems (Max. 1600 indoor units),
suitable for huge scale application.
RELIABILITY AND EASY MAINTENANCE
„ „
● Stand-alone transmission network, allows each equipment to operate individually, thus failure
of the units does not affect other indoor units operation.
● When a failure occurs, the error code is displayed on the individual controller and central
controller excepting Wireless Remote Controller.
● Also error histories can memorized by each individual controller and central controller
excepting Wireless Remote Controller.
● System Controller and Web Monitoring Tool allow to monitor operation status in real time via
Internet, and enable quick diagnoses.
● Maintenance work is improved efficiency, because Service Tool can be connected to
anywhere on the transmission line.
