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:

IU Errors Explanation
In the parameter “Description” will be specified the Daikin Error Code and its explanation (as it is specified
in the following table). In the “value”, returns an Integer value that converted to hexadecimal
representation obtains a Daikin error code, using Daikin Malfunction Code Table.
The process used to get the Daikin error code from the Integer value is:

15
Installation and User Manual
DZK BACnet Interface
Rev. 2.00 Date 10-2018
1. Read the integer value from the BACnet object: Value D
2. Convert it from decimal to Hexadecimal: 0xXY
3. Obtain the #row and #column from the Hexadecimal value:
-Row = X-1
-Column = Y
4. Check the Daikin Malfunction Code Table (see section Daikin malfunction error code table).
*Note: Row and column index start in 0.
Example:
1. Value read from the BACnet object: 148
2. Convert it to Hexadecimal value: 0x94
3. Obtain the #row and #column from the Hexadecimal value:
-Row = 9 – 1 = 8
-Column= 4
4. Check the Daikin Malfunction Code Table:
-Row: 8 System U
-Column: 4 Communication error between indoor unit and outdoor unit, communication error
outdoor unit and BS unit.
DETAILED DESCRIPTION OF THE OBJECTS
COMMON TO ALL OBJECTS
For each DZK:
1. When the indoor unit is communicating normally, a communication can be established between the
DZK BACnet Interface and the indoor unit. The BACnet building management system will then have
access to the DZK unit’s objects.
2. If the communication between the DZK BACnet Interface and the system is not correct, or if a request
for information related to a communication object that is not present in the DZK system the object's
property "Out of service" is activated.
IU STATUS ON/OFF
The DZK BACnet Interface will report the status of the IU when interrogated by the BACnet network. This is
a Read only object.

16
Installation and User Manual
DZK BACnet Interface
Rev. 2.00 Date 10-2018
DZK SYSTEM INPUT ALARM
This object represents the state of alarm input available to the DZK main board (normally closed contact),
indicating whether this input is active or inactive. When this input is active, the system remains in STOP. This
is a Read only object.
DZK GLOBAL VENTILATION (STATUS)
If the DZK system is configured for Global Ventilation, the Global Fan Object will show as active. Otherwise,
it will show as inactive. This is a Read only object.
DZK AUX. HEAT1 AND AUX HEAT2 (STATUS)
If the DZK system is configured with Auxiliary Heat, when one or both (if 2 stages are configured) will show
the active stages. If there is no demand for auxiliary heat, then it will show both as inactive. These are Read
only objects.
Z# ON/OFF
Because the zone thermostats can be deactivated (Off), that will cause the zone to leave the damper open
but will not generate demand, the DZK BACnet Interface will report the status of each specific zone. Through
the BACnet platform, any zone can be set On/Off. These are Read/Write objects.
Z# LOCAL VENTILATION
Given the capability of each zone to individually activate ventilation this status is also reported to the BACnet
platform, which in turn can remotely activate or deactivate this function. These are Read/Write objects.
Z# VACATION OVERRIDE
Vacation override can be enabled or not in each zone. This object represents if the Override time of the
Vacation mode in the zone is active or inactive. This is read only object.
Z# UNOCCUPIED OVERRIDE
Unoccupied override can be enabled or not in each zone. This object represents if the Override time of the
Unoccupied mode in the zone is active or inactive. This is read only object.
DZK COMMUNICATION ERROR
This object monitors the communications between the DZK BACnet Interface and the DZK System. It will be
activated when the DZK BACnet Interface loses communication with DZK control board. This is a Read only
object
Z# ROOM TEMPERATURE
The BACnet platform can obtain the actual room temperature for any zone. These are read only objects.

17
Installation and User Manual
DZK BACnet Interface
Rev. 2.00 Date 10-2018
INDOOR UNIT (IU) SETPOINT
The IU set point is the result of a computation including the overall zone demand and the return
temperature read by the IU. This set point is shown in the Daikin controller, and reported to the BACnet
platform. This is Read only object.
Z# HEAT AND COOL SET POINTS
Each thermostat can be configured for a heat and cool set point, and those values are reported to the BACnet
platform, and can be changed from it. These are Read/Write objects.
INDOOR UNIT (IU) SPEED
This parameter refers to the IU fan speed. Depending on the number of open zones and the value selected
in the Q-Adapt parameter in the DZK system, the IU fan will run at a given speed, and the step at which the
fan is running is reported to the BACnet platform. This is read only object.
INDOOR UNIT (IU) ERRORS
If the IU generates an error, it will be reported by the DZK BACnet Interface to the BACnet platform. This is
read only object.
DZK ERROR
If the DZK generates an error, it will be reported by the DZK BACnet Interface to the BACnet platform. This
is Read only object. The errors are:
0 àWhen operating normally.
9 àCommunication error between DZK control board and DZK Interface board.
10 àError in DZK BACnet Interface.
11 àCommunication error between Indoor Unit and DZK Interface board.
DZK OPERATION MODE
The DZK BACnet Interface will report the system operation mode, represented by a number from 1 through
5. This is a Read/Write object. The modes are:
1. Auto
3. Heat
5. Emergency heat
2. Cold
4. Dry
In VRV Heat Pump installations, all the indoor units must work in supported/compatible operation modes,
the operation mode of the DZK connected to a slave indoor unit could be restricted or limited by the
operation mode selected in the DZK connected to the master indoor unit.
If in the same VRV Heat Pump installation, a DZK unit is connected to a slave indoor unit and another indoor
unit is configured as the master (with or without DZK connected to):

18
Installation and User Manual
DZK BACnet Interface
Rev. 2.00 Date 10-2018
-When the master IU is operating in Fan mode, the DZK will send the current mode (cool, heat or dry)
to the BACnet interface, if a cooling or heating demand exits.
-If no cooling or heating demand exits, the DZK will report STOP to the DZK BACnet Interface.
DZK USER MODE
The DZK BACnet Interface will report the system user mode, represented by a number from 1 through 6.
This is a Read/Write object. The modes are:
1. Stop
3. Unoccupied
5. Eco
2. Comfort
4. Night time
6. Vacation
DZK ADDRESS (DK AIRNET)
The DZK BACnet Interface will read from the IU the DK AirNet address and report it to the BACnet platform.
The information regarding the indoor unit address is sent to the DZK system in the initialization process or
the indoor unit startup after powering on the unit. Or, if this information is queried from the NAV-controller
unit.
Because of that, in the situation where the DZK system is powered up after the indoor unit, it will be required
to access this parameter via the NAV-controller so that information is forwarded to the system DZK. This is
read only object.
DZK GROUP ADDRESS – GROUP (DK GROUP ADDRESS)
This object represents the group address of the indoor unit. This address is the same that returns the Daikin
system via the Itouch connected to the BACnet network.
Like the above object, the information is sent in the process of initiation or startup of the indoor unit, or
when this information is queried to the indoor unit NAV-controller. This is read only object.
Z# COOLING AND HEATING DEMAND (%)
Each zone generates simultaneously values for heating and cooling demand, to allow the auto changeover
function to define which mode will select to operate the system. Those values are reported to the BACnet
platform as a percentage of the total demand. These are read only objects.
Z# OPENING STEP DAMPER
When the DZK system is configured for Modulating dampers, depending on the temperature difference
between room and set point, the dampers will open to a given step. This is the step reported to the BACnet
platform. These are read only objects.
Z# HUMIDITY
The BACnet platform can obtain the actual humidity for any zone. These are read only objects.

REPORT FUNCTION
COV NOTIFICATION
The COV notification with subscription (DS-COV-B) is supported.
COV notification with subscription (subscribed COV)
COV subscription request is received by the Subscribe COV service.
1. Setting COV generation with/without confirmation. Supported as defined in the BACnet
specifications.
2. Validity period for notification.
•Supported as defined in the BACnet specifications.
•When executing COV notification at status change, the system calculates the difference between
the current time and registered time, and then it will delete the COV notification if the difference
is larger than the validity period.
•Therefore, if the clock is changed, the actual validity period may differ from the defined period.
3. Memorization at power off.
•Not supported.
•Since the subscribed information is not saved, it will be deleted at power off.
•The BACnet specifications do not require memorization at power off.
4. Notification recipient information.
•The notification recipient information is not visible from the BACnet. The BACnet specifications
do not require network visibility.
5. Number of notification recipients.
•X clients per object.
•Specifying more than 5 recipients will return ErrorPDU of Error Class = SERVICES,
•Error Code = COV_SUBSCRIPTION_FAILED.
COV notification is supported for all the objects for the indoor unit.
TROUBLESHOOTING
THE DZK SYSTEM DOES NOT DETECT THE DZK BACNET INTERFACE
Verify the correct connection between the DZK BACnet Interface in the DZK main control board (see section
Specifications and device elements):
-Verify that the LED D9 (Microswitch performance) is blinking.
-Verify that LEDs D7 and D8 are alternately blinking.
If the above does not verify, check the correct connection of the DZK BACnet Interface on the DZK main
control board, verifying the 5-pin connector.

THE DZK BACNET INTERFACE CANNOT BE CONNECTED (I)
Verify that LEDs “A” and “B” (see section Specifications and device elements) are blinking, and those in the
Ethernet connector are active.
If the above is not true, check that the Ethernet cable is properly connected.
THE DZK BACNET INTERFACE CANNOT BE CONNECTED (II)
Check the following possible causes:
1. Using the Ethernet (LAN)
-Check the state of the LEDs of the DZK BACnet Interface. If all of them are blinking at the same
time, it means the IP selected for the DZK BACnet Interface is already being used by other device.
Access settings (see section IP configuration) and change the parameter IP address.
-Verify that the IP address set for the PC is correct (Refer to 7.2 for the correct IP address and setting
procedure.)
-Verify the Ethernet cable connection:
•Verify if connecting via the hub: straight cable.
•Verify communication with the Interface for use in BACnet® by testing the operation from the
PC directly: Use a crossover cable.
-Verify that the PC's LAN communication port is active.
-If using the hub, verify that the hub is powered on.
-Do a PING to the DZK BACnet Interface from the PC to verify the Ethernet Link (See below).
[How to execute a PING to the BACnet Interface].
1. From the PC's desktop, select "Start", "Program", "Accessories", and "Command Prompt". The
dialog box shown below opens.
2. Use the PC's key board; enter the BACnet gateway IP address in [1]. Ex. When Interface for use in
BACnet®'s IP address is "150.35.20.62", enter "ping 150.35.20.62" and press the Return key.
2. If you can see information as shown in [2], the LAN connection is established. Start the test operation
program and try connection again.
If you see information as shown in [3], the LAN connection is not established for some reason. Check the PC's
settings, etc. again.
