Part 1. Overview
1. DCM014A51 iTM BACnet® Server Gateway
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.
The iTM BACnet Server Gateway option eliminates the need for an additional hardware interface for the
BMS to monitor and control a VRV system. The iTM BACnet Server Gateway option provides seamless
control-logic integration between the iTM and BMS.
Figure 1. iTM BACnet® Server Gateway
1.1 Features:
•Direct connection on iTM using the BACnet/IP Protocol.
•BACnet virtual router function implemented:
» Individual BACnet device ID assigned to each indoor unit group address.
»Indoor unit group names created in the iTM are visible on the BMS.
•Easy commissioning using CSV file.
»Available objects can be configured for each indoor unit.
•Support Change of Value (COV) notifications to BMS.
•Configurable as a BACnet foreign device if BBMD exists on a different subnet within BACnet
network.
•Independent heating and cooling setpoints for occupied and unoccupied periods.
•Individual min/max Setpoint Range Limitation for heat and cool modes.
•The iTM’s auto-changeover, setpoint range limitation, setback, dual setpoint logic, and
schedule can be accessed by the BMS.
The intelligent Touch Manager (hereinafter referred to as "iTM") supports the BACnet 2004 protocol
(hereinafter referred to as "BACnet specifications"). The iTM operates as a BACnet server that provides
BACnet objects to monitor/operate indoor units connected to the DIII network in response to requests
from a Building Management System (BMS), i.e., BACnet client.

Part 1. Overview
DCM014A51 Design Guide 7
This document describes the operation for the BACnet® Server Gateway option for the iTM.
1.2 BACnet Compatibility
•Packaging of the VRVindoor unit objects:
»Compatible with BACnet (ANSI / ASHRAE-135).
»Compatible with BACnet / IP (ISO16484-5).
•Conforming to Safety and Electromagnetic Compatibility (EMC) rules and regulations.
1.3 System Outline
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.
3. Up to 128 indoor unit management points can be controlled and monitored through the iTM
BACnet Server Gateway.
4. Up to 7 additional DIII-Net communication systems can be added with optional iTM Plus
Adaptors. The iTM Plus Adaptor is intended for use with the iTM, and shall not be used
independently.

Part 1. Overview

2. VRV System Overview
The Daikin VRV system consists of outdoor units, indoor units, zone controllers, centralized controllers,
and BMS interfaces. The customizable Daikin control system is built around the VRV system, and does
not require advanced field engineering (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.
2.1 Types of Daikin VRV Systems
The VRV system can consist of either a Heat Recovery system, Heat Pump systems, or system that has
a combination of both.
1. Heat Recovery systems can provide simultaneous cooling and heating to each indoor unit
served by the same outdoor unit with use of Branch Selector Boxes (BS Box).
Figure 3. Heat Recovery System
2. Heat Pump systems only allow each outdoor unit and its connected indoor units to operate in
either cooling or heating mode. Multiple Heat Pumps systems can be installed to operate
independently in either cooling or heating mode.

DCM014A51 Design Guide 9
2.2 DIII-Net System and Group Addresses
1. The DIII-Net system consists of the following:
a. Up to 10 VRV outdoor units (daisy chained).
b. Up to 128 indoor units.
2. The iTM (central controller) and DIII-Net system consists of the following:
a. Up to 10 VRV outdoor units (daisy chained).
b. Up to 64 indoor unit groups (128 indoor units).
c. Up to 7 iTM Plus Adaptors can be connected to a single iTM. Each adaptor can contain up to
64 group addresses and 10 outdoor units.
3. When a centralized controller is connected to the DIII-Net system, a unique group address
must be created for each indoor unit to be monitored and controlled by the central controller.
4. Group Address:
a. Indoor units are assigned unique group addresses (up to 64 per DIII-Net system) manually
during the VRV commissioning.
b. Addresses are as follows: 1-00 to 1-15, 2-00 to 2-15, 3-00 to 3-15, 4-00 to 4-15.
c. With the use of the iTM Plus Adaptor, up to 8 DIII-Net systems can be connected to a single
iTM. Each DIII-Net system will be assigned a port number with the iTM being port 1. For
example, an indoor unit connected to the iTM will have the complete group address of 1:1-
00. Similarly, each additional system will be assigned a port number 2 to 8 (2:1-00, 3:1-00,
etc.).
2.3 Remote Controller Group and Group Address
1. A remote control group consists of 1 -16 indoor units connected (via P1P2 daisy chain) to the
same remote controller. The indoor unit group allows for a maximum of 2 remote controllers
to be connected to the same remote controller group. It is not required to have a remote
controller connected to an indoor unit. If no remote controllers are used there should be a
centralized method for monitoring and controlling the indoor units.
2. Assigning a group address to a single indoor unit (typical configuration):
* F1F2 = DIII-Net ** P1P2 = Remote Controller line
Figure 5. Assigning Group Address to a Single Indoor Unit

Part 1. Overview
10 Design Guide DCM014A51
3. Assigning one group address to a remote controller group:
Figure 6. Assigning One Group Address to a Remote Controller Group
4. Assigning a group address to each indoor unit in a remote controller group:
Figure 7. Assigning a Group Address to Each Indoor Unit in a Remote Controller Group
Note: As shown in the figures above, a remote controller group consists of several
indoor units wired to the same remote controller. A remote controller group consists of
1-16 indoor units that can be started or stopped simultaneously. For units without a
remote controller, each unit is treated as a group.
