Daikin DZK Zoning Kit and FXMQ-PBVJU DC-Ducted Ceiling Unit
ENERGY-INTELLIGENT™ HEATING AND COOLING SYSTEMS
The Daikin Zoning Kit (DZK)
The optional DZK increases the flexibility of Daikin VRV and SkyAir systems for residential and commercial applications. It adds a Zoning Box to an indoor unit fan coil (FXMQ_P or FBQ_P series), allowing several separate ducts to supply air to different, individually-controlled zones. A zone can be a room, part of a room, or several rooms. This flexible and scalable Zoning Kit integrates seamlessly with the indoor unit fan coil controls.
The DZK system controls work with the regular Daikin zone controller (e.g., BRC1E73) to establish the required set-point, fan speed, and mode of operation, which is then requested to the VRV indoor unit via the Daikin zone controller. This allows the internal DZK control algorithms to monitor the number of zone dampers in operation and their positions, adjusting the VRV indoor unit operation accordingly.
The DZK system is not directly compatible with Daikin centralized control options such as iTM and iTC.
DZK BACnet® Gateway Module [NEW]
If VRV systems are installed with the DZK system to achieve various zoning solutions, and there is a requirement to monitor and control the DZK zone dampers from a centralized control system, the DZK BACnet Gateway module can be utilized. The DZK BACnet Gateway module is compatible with any BACnet/IP compatible Building Management System.
Zoning Box with Control Board
The Zoning Box in the DZK mounts easily on Daikin's Indoor Unit FXMQ_P or FBQ_P series fan coils. It comprises an enclosure, individually motorized dampers, and a control box. It is available in different sizes and damper configurations. By utilizing ducts for air supply, it can control the air temperature in up to 6 zones. The wired thermostat and wireless thermostats provide temperature inputs and user interfaces for programming and adjustment of control functions for each zone.
Wireless Thermostat
The wireless backlit touch-screen thermostat for the DZK can control the temperature for a zone while displaying the air temperature, system time, and day of the week. Additional functions include adjusting set point temperature, automatic configuration, local ventilation activation, and vacation mode. A wireless thermostat is required for zones not controlled by a wired thermostat.
Wired Thermostat
The wired thermostat for the DZK features a graphical colored, touch-screen interface with text menus, intuitive icons, and guided scheduling capability. It displays temperatures and operating values, and selects the operating mode for the system. At least one wired thermostat is required per DZK.

Note: "-2" in the Product Number indicates BACnet/IP functionality. For configuration of DZK systems with BACnet/IP functionality, only Product Numbers ending with "-2" or "-2-W" can be used. For configuration of DZK systems without BACnet, either products with, or without, the BACnet functionality can be used, even "mix and match".
DC-Ducted Ceiling Unit
Powerful, Concealed, Flexible
When combined with the DZK, the ceiling-mounted DC-Ducted unit is ideal for small to large spaces requiring a concealed air-conditioning system. It is extremely powerful, and its compact design allows it to be completely concealed, making it perfect for retail, classrooms, offices, banks, restaurants, shops, and hotels common areas.
Features and Benefits
- Capacity range up to 54 MBH.
- Energy efficient due to the DC fan motor.
- Ideal for use with the optional Daikin Zoning Kit, DZK.
- Configurable auxiliary heater control logic.
- Advanced economizer control logic.
- Enhanced indoor air quality and LEED ready with MERV 13 filter options.
- Ease of installation with auto-adjusting airflow at commissioning based on external static pressure.
- Flexible ductwork design with ESP capabilities up to 0.8" W.G.
- Installation flexibility with a low profile, compact design at less than 12" in height.
- Easy maintenance with complete service access from below.
- Option to permanently turn off the condensate pump via field settings.
Auto Adjust External Static Pressure
After installation, if the actual duct resistance is lower than expected at the time of design, the airflow may be too high. The automatic air-flow adjustment function allows the unit to adapt its fan speed to a lower curve, reducing the airflow. The airflow will always remain within 10% of the rated airflow due to the availability of multiple fan curves (more than 8 fan curves available per model).
Key features include: Condensate Pump [?] as Standard, Outside Air Integration Possible [?️].
Available controller options include BRC1E73 (option), BRC2A71 (option), and BRC4C82 (option).
