Daikin BS1Q10A VRV IV Branch Selector Box – Individual Heat Recovery

Daikin FXLQ20P VRV indoor unit

The Daikin BS1Q10A is a compact single-port branch selector box designed for compatible Daikin VRV IV heat-recovery systems.

The BS1Q10A is used as part of a VRV heat-recovery installation to connect compatible indoor units to the system’s refrigerant network.

Daikin describes the BS1Q-A range as a series of individual and multi-branch selector boxes for VRV IV heat recovery, designed to provide flexible system configurations and simplified installation.

What Is the Daikin FXLQ20P VRV indoor unit?

The BS1Q10A is a VRV IV heat-recovery branch selector box, sometimes referred to as a BS box or branch selector.

Unlike an indoor air-conditioning unit, the BS1Q10A is a system component used within a compatible Daikin VRV heat-recovery installation.

Its purpose is to facilitate the connection between the VRV outdoor system and compatible indoor units within the heat-recovery configuration.

This makes the product particularly relevant to:

• HVAC contractors
• VRV installers
• Commercial building projects
• VRV system designers
• HVAC maintenance companies
• Replacement and refurbishment projects
• Multi-zone commercial installations

Single-Port Branch Selector Box

The BS1Q10A is a single-port BS box.

Daikin’s European catalogue identifies the BS1Q10A as a single-port branch selector for VRV IV heat-recovery systems.

The single-port design can provide flexibility when planning individual branches within a larger VRV heat-recovery system.

Connectable Indoor Units

Daikin’s European documentation specifies that the BS1Q10A can accommodate:

1–6 indoor units

and supports a connectable capacity index of:

15–100

Daikin also lists the BS1Q10A as accepting indoor-unit sizes within the 15–100 range.

The exact number and combination of indoor units must be determined according to the applicable Daikin system design and compatibility requirements.

VRV IV Heat Recovery

The BS1Q10A is designed specifically for VRV IV heat-recovery applications.

Daikin lists the BS1Q-A range as compatible with specified VRV IV heat-recovery systems, including:

• REYQ-U
• RWEYQ-T9
• RQCEQ-P3

The exact compatibility depends on the system generation and configuration.

Therefore, customers should verify their existing or planned outdoor-unit model before ordering.

Daikin FXLQ20P VRV indoor unit Compact Design

The BS1Q10A is designed as a compact component for VRV system installations.

Daikin’s European documentation lists the BS1Q10A dimensions at approximately:

207 mm H × 388 mm W × 326 mm D

European distributor technical data also confirms these dimensions.

The compact format can help installers integrate the branch selector into appropriate service and installation spaces.

No Drain Piping Required

One advantage highlighted by Daikin for the BS1Q-A range is that the branch selector boxes are suitable for remote rooms because no drain piping is needed for the BS box itself.

This can simplify certain installation arrangements compared with indoor units that require condensate drainage.

Flexible VRV System Design

The BS1Q-A range is designed to provide flexibility when planning VRV heat-recovery systems.

Daikin highlights:

• Compact design
• Lightweight installation
• Flexible BS-box configurations
• Fast installation
• Multi-tenant applications
• Technical cooling functionality
• Integration with compatible VRV heat-recovery systems

This makes the BS1Q10A relevant for commercial HVAC projects where flexible heat-recovery system design is required.

Technical Cooling Applications

Daikin’s documentation notes that the BS1Q-A range can support the integration of server rooms into a heat-recovery solution through its technical cooling function.

This can make the technology relevant to certain commercial and technical environments, subject to the complete VRV system design.

Multi-Tenant Applications

The BS1Q-A range is also designed to support multi-tenant applications.

This can be useful in commercial properties where different zones or occupants require independent climate-control arrangements within a larger VRV heat-recovery installation.

The exact system design should be completed according to Daikin’s technical requirements.

Installation Benefits

Daikin highlights the compact BS-box design and faster installation characteristics of the BS1Q-A range.

The branch selector box can be incorporated into an appropriately designed VRV heat-recovery system without requiring a conventional condensate drain connection for the box itself.

Professional installation and system commissioning are required.

Daikin BS1Q10A Applications

Commercial Buildings

The BS1Q10A can form part of a larger VRV heat-recovery system in offices, commercial buildings and other suitable applications.
