OVERVIEW
OUTLINE AND FEATURES
The DZK BACnet Interface allows a Building Management System to control all variables of the DZK
systems. The DZK BACnet Interface uses a standard open protocol based on ASHRAE Standard 135, and its
objects are:
-Compatible with BACnet (ANSI /ASHRAE-135)
-Compatible with BACnet/IP (ISO16484-5)
The DZK BACnet Interface is a Plug&Play device for DZK, and it allows controlling and monitoring the
following variables:
•Indoor Unit status.
•Fan status and Fan Speed.
•Auxiliary Heat stages status.
•Global Ventilation status.
•Operation Mode Control status.
•On/Off control for each zone.
•Set point setting for Cooling and Heating for each zone.
•Room Temperature in each zone.
•Local Ventilation activated/deactivated for each zone.
•Unoccupied Override activate/deactivate.
•Vacation Override activate/deactivate.
•Opening Damper Status for each zone.
•Indoor Unit and DZK errors.

FUNCTIONAL SPECIFICATIONS
INTRODUCTION
When the DZK BACnet Interface is used in a BACnet/IP network, it operates as a BACnet interpreter using
the services defined by the BACnet to return the status of the Daikin Zoning Kit (DZK). It also sends
configuration commands to them, in response to requests from a BACnet building management system
(BMS) (i.e., BACnet client) which support the BACnet (ISO16484-5, ANSI/ASHRAE135) protocol.
The DZK BACnet Interface is a plug and play device, which, when connected to the DZK main control board
and to a BACnet network, it configures itself and configures the main board to work with the BACnet
network. The installer can modify the IP address and BACnet device ID.
When the DZK BACnet Interface is connected to the DZK Main Control Board, a new item appears in the
installer configuration menu, as follows:

Installation and User Manual
DZK BACnet Interface
Rev. 2.00 Date 10-2018
The Ethernet cable should be connected to the DZK BACnet Interface gently. Once the control board has the
interface connected, it will auto-detect the presence of the DZK BACnet Interface and automatically set the
parameters to enable the BACnet operation.
From the main screen, press and hold the icon until the “Enter pattern” screen is displayed. Enter the
sequence below to access the configuration menu, select the System settings and then select the BACnet
setting.
The new option that appears in the Configuration menu
Note: The device will only connect to internet if the “Remote assistance” option is enabled.
Keep in mind: For proper operation, DZK systems must be powered up before the indoor unit.
DEVICE ID AND PORT
In the BACnet menu, press the icon . For the proper identification on the BACnet/IP network and
operation of the DZK BACnet Interface, it may be required to modify the Device ID (by default 1000) and the
Port parameter (by default 47808). These properties can only be modified locally from the Main Wired
Thermostat.

IP CONFIGURATION
In the BACnet menu, press the icon . For the proper operation of the DZK BACnet Interface with the IP
network, it is required to configure the following network parameters:
-IP Address (default 192.168.0.100)
-Subnet mask (default 255.255.255.0)
-Gateway IP (default 192.168.0.1)
These properties can only be modified locally from the Main Wired Thermostat.
To configure them, access to IP Configuration menu, from BACnet menu:
