1 Outline and Features
1. Managing the information on 128 groups of air-conditioners (main units only).
2. Up to 256 groups manageable and controllable at once by adding the optional DIII board.
3. Packaging of air-conditioner objects
* Compatible with BACnet (ANSI/ASHRAE-135)
* Compatible with BACnet/IP (ANSI/ASHRAE-135a)
* Compatible with IEIEJ/p-0003-2000 (plan)
(IEIEJ is Institue of Electrical Installation Engineers of Japan)
4. Conforming to European Safety and EMC rules and regulations.

NOTES
1 A group consists of several indoor units that can be started or stopped simultaneously. As shown in the figure above, a group consists of several
indoor units wired to the same remote control. For units without remote control, each unit is treated as a group.
2 Several groups are registered as a zone with the centralised remote control. By pushing 1 button of the centralised remote control, all groups within
the same zone can be turned on or off simultaneously.
Building management 1 system controls and monitors air-conditioning equipment by the block. A block consists of 1 or more groups (max. 16), and
can be set without regard for the zones mentioned above. You must, how-ever, take the following things into consideration:
3 If the air-conditioning mode is switched, as a premise, permission for cool/heat selection for indoor units (by remote controller or central remote
controller) must be designated within the program.
4 Program status is basically monitored by observing the data of a representative unit. The contents which can be monitored are therefore restricted
if the representative unit is designated as an adaptor, etc.
Block registration is accomplished through signal transmission from the building control system to the cooler-conditioning system. Because
configuration can be changed while receiving power even after operating, maintenance from the maker of the air-conditioning equipment is not required
when changing the configuration.
Name Functions
BACnet Interface (DMS502A51) Interface unit to allow communications between VRV and BMS. BMS ready to run and monitor the air-conditioning systems through BACnet
communications. Up to 128 groups.
Optional DIII board (DAM411B51) Expansion kit, installed on the BACnet Interface (DMS502A51), to provide 3 more DIII-NET communication ports. Not usable independently. Up to 256
groups.

Group: Group of units connected by local remote control
Zone: Several groups are registered as a zone by button
operation of the centralised remote control. Control is
then effected by the zone using the centralised remote
control.
