Function<br />
� Interface for use in BACnet ®<br />
Interface unit to allow communications<br />
between VRV and BMS.<br />
� Parallel interface<br />
Carries out operation and monitoring function<br />
of each indoor unit by contact and analog<br />
signal.<br />
� Interface for use in LONWORKS ®<br />
The LON Gateway functions as the interface for<br />
a building monitoring system and cannot be winstalled<br />
on the DIII-NET along with following<br />
equipment / devices that have similar functions.<br />
� Air conditioning charges are accumulated for<br />
each indoor unit.<br />
� Registration can be made for each tenant.<br />
� Operation/stop/abnormality monitoring for an<br />
indoor unit is available for each tenant.<br />
� Normally open or momentary open type<br />
contactor<br />
� 12~24 VDC or no-voltage<br />
� Various control methods available by mode<br />
select switch<br />
� Voltage, no-voltage selector switch<br />
� Alarm and operation display signal (novoltage)<br />
� Selector switch of zone/individual of alarm<br />
display<br />
� Remote temperature setting (resistance input<br />
of 0~135Ω)<br />
� Selector switch for remote controller<br />
temperature setting enable/inhibit<br />
∗ For group unified control, the setting becomes<br />
the same for all connected indoor units, and<br />
each indoor unit is controlled individually by<br />
built-in thermostat.<br />
∗ In case of using wiring adaptor for Electrical<br />
Appendices (2), the control by 2 remote<br />
controller is not available.<br />
� Function is the same as above.<br />
Used only when 3 groups or more of HRV are<br />
interlocked and operated.<br />
∗ In case of integrated zone control, settings for<br />
all indoor units connected to respective<br />
groups become the same, and each indoor<br />
unit is controlled by built-in thermostats.<br />
� Necessary when electric heater and<br />
humidifier are incorporated optionally<br />
� Operation indicating signal is made by taking<br />
out compressor operation signal.<br />
� Unification adaptor for computerized control<br />
allows you to simultaneously turn indoor units<br />
connected to the central remote controller on<br />
or off or display at the central monitor panel,<br />
etc.<br />
� Interface adaptor for SkyAir series, wiring<br />
adaptor for other air conditioners and wiring<br />
adaptor for ‘H’ indoor unit are for connection of<br />
optional controllers for centralized control.<br />
Note) Central control units such as central remote controller cannot be used at the same time.<br />
Standard Number of<br />
Controllers<br />
Interface for use in<br />
BACnet ® :<br />
Up to 256 indoor<br />
units (256groups)<br />
When the option DIII<br />
board is used<br />
Parallel Interface,<br />
Interface for use in<br />
LONWORKS ®<br />
Up to 64 indoor units<br />
(64 groups)<br />
A charge<br />
management unit<br />
can cover 64 indoor<br />
units.<br />
1 PC board controls<br />
1 indoor unit.<br />
1 PC board<br />
simultaneously<br />
controls 1 group of<br />
indoor units (max. 16<br />
units).<br />
1 adaptor could<br />
control a maximum<br />
of 64 groups with 1<br />
group consisting of a<br />
maximum of 16 units<br />
(up to 126 units in<br />
total).<br />
1 adaptor controls<br />
electric heaters and<br />
humidifiers.<br />
� Simultaneously controls<br />
by one unification adaptor<br />
for computerized control,<br />
all indoor units connected<br />
to a central remote<br />
controller.<br />
� Controls one indoor unit by<br />
one interface adaptor for<br />
SkyAir series, wiring<br />
adaptor for other air<br />
conditioners, and wiring<br />
adaptor for ‘G(J)’ indoor<br />
unit.<br />
