BACnet Gateway

Network Solution

Main features

Ensures precise and efficient monitoring and control of VRV and HRV systems. Also Split & Sky Air units can be connected via an optional interface adapter
Is a flexible, multi purpose system
Control mechanism is BACnet^TM
Provides easy integration in to building management systems (BMSs) including management of all building installations in remote control or interlocked control

Open Network Integration

Daikin has released a new adapter that requires no additional interfaces nor gateways for connection to BACnet^TM networks equipment and building control systems. BACnet^TM networks are recognised worldwide as the de facto standard within the building controls industry. BACnet^TM data communication protocol makes it possible to control access, energy management, fire/life/safety, HVAC and lighting etc.

Quick and Easy Installation

The open protocol specification gives local system integrators complete design freedom. Also the ability to combine individual items of equipment into BACnet^TM networks reduces the time and costs required for wiring work.

Unlimited Site Size

The network adapter can be connected to 64 groups (256 with optional accessory). Maximum value of

BACnet Gateway is set by BACnet BMS.

RoHS Compliance

Restriction of Hazardous Substances in electrical and electronic equipment (2002/95/EC). Hazardous substances include Lead (Pb), Cadmium (Cd), Hexavalent Chromium (Cr6+), Mercury (Hg), Polybrominated biphenyls (PBB) and Polybrominated diphenylether (PBDE).

Although RoHS regulations are only applicable to small and large household equipment, Daikin environmental policy nevertheless ensures that VRVIII will be totally in line with RoHS.

Functions

Air conditioning status monitoring: 64 groups of indoor units and 10 outdoor units. (Max 256 groups of indoor units and 40 outdoor units, when optional DIII board is added)1

Indoor unit error monitoring
Indoor (air inlet) temperature monitoring
Filter sign monitoring
Thermostat status
Compressor operation status
Indoor fan operation
Heater operation
Air direction monitoring
Air flow rate monitoring
Forced thermostat off/on monitoring
Alarm sign
PPD data2

The transmission of VRV PPD (power proportional distribution) data is possible by BACnet communication for BMS system.

Digital Di board (DAM412B51) is required
If exceeding the stated number of outdoor units, DIII-NET expander adapter allows easy system connection as long as restrictions are observed.
