1-4. CONTROL SYSTEM FEATURES
„ „
SIMPLE WIRING SYSTEM
● A single transmission line can connect equipment across multiple refrigerant circuits.
● Non polar 2-conductor transmission cable.
● Central control equipment can be connected anywhere on the transmission line, it is not
necessary to connect the indoor units to each outdoor unit.
„
„
-Simplifies network installation and start-up
„
-Reduces the total wiring required
„
-Helps prevent improper wiring
-Reduces total installation time
„ „
LARGE BUILDING APPLICATIONS
● A single VRF network can control an entire building using:
„
- Total transmission wiring length can be extended up to 11,811 ft. (3,600 m). (with signal
amplifier unit.)
„
-Up to 400 indoor units per group
-Up to 100 outdoor units per group
„
-Touch Panel Controller can be used for primary central control.
„
-Multiple Touch Panel Controllers may be sued to provide convenient control for multiple
convertor (Refer to 3-1.)
„
- Can control Fujitsu mini-split and HFI models using a Network Convertor (Refer to 3-1.)
„
● System Controller allows to control up to 4 VRF network systems (Max.1,600 indoor units),
suitable for huge scale application.
„ „
RELIABILITY AND EASE OF MAINTENANCE
● Stand-alone transmission NETWORK allows for each unit to operate separately; therefore,
an error at one unit does not effect the performance of the remaining units.
● When a failure occurs, the error code is displayed on the individual controller and central
controller. (except Wireless Remote Controller)
● Error history is stored in each individual controller and in the central controller (except
wireless controller).
● System Controller and Web Monitoring Tool allow to monitor operation status in real time via
INTERNET, allowing for a quick evaluation of VRF systems.
● Service tool can connect anywhere on the transmission line, allowing building owner to
quickly evaluate the performance of the VRF system.
