    The intelligent Touch Manager (iTM) is now capable of serving as a BACnet® interface for Building Management System (BMS) integration. The iTM BACnet® Server Gateway option (DCM014A51) will provide BMS integrators the ability to monitor and control VRV indoor units via the BACnet®/IP protocol.

    1. Typical BACnet® Server Gateway Application: Figure 2. Typical Daikin VRV System 2. The iTM BACnet® Server Gateway (DCM014A51) software option provides communication between the VRV system and the BMS. The operation and monitoring of the VRV systems through BACnet® communication uses the BACnet®/IP protocol.

    (i.e., programming) for the control of the VRV system, except for field settings configurations. The iTM BACnet® Server Gateway can be used for monitoring, scheduling, control, and interlock operation. A BMS can be used in conjunction with the Daikin controllers to share operation workload to reduce project costs.
