Advantage Digital Round VAV Diffuser (ADVR)

• Model: ADVR — Round digital VAV diffuser (Advantage family)
• Face Size: 24" (600 mm) round plaque diffuser
• Inlet Sizes: 6", 8", 10", and 12" round
• Construction: Steel housing with powder-coated round face and aerodynamic damper assembly

• A room temperature sensor sends continuous feedback to a microprocessor controller mounted at the diffuser.
• The controller uses space temperature, inlet/supply air temperature, and setpoint to modulate the electric damper.
• Digital PI (Proportional + Integral) control provides smooth, stable temperature control without hunting or overshoot.
• Damper and plaque design maintain discharge velocities as the diffuser modulates, providing consistent throw and room mixing.

• Round, plaque-style face blends with circular ceiling and duct layouts.
• Individual zone control at each diffuser for improved comfort and flexibility.
• Fast response to load changes thanks to direct digital control and high-torque motor.
• Compatible with optional BACnet interface for integration with building automation systems (Advantage family option).
• Can be used with “drone” diffusers that follow a master ADVR for multi-diffuser zones.

• APM – Advantage Power Module: Central 24 VAC power supply for multiple Advantage diffusers.
• ARC – Advantage Relief Collar: Pressure-relief collar to bypass excess static into the ceiling plenum.
• PIM – Pressure Independence Module: For pressure-independent operation under varying static conditions.
• DMS – Diffuser Measuring Station: Flow measurement option for CFM monitoring and BAS reporting.
• BACnet Interface: Optional interface for room temperature, setpoint, and load visibility at the BAS.

ADVR uses the same Advantage digital control platform as ADV and ADVB, with a round architectural face to match circular ceiling and ductwork designs.
