Advantage Digital Square VAV Diffuser with Built-In Thermostat (ADVB)

• Model: ADVB — Square plaque digital VAV diffuser with built-in thermostat
• Series: Advantage Digital VAV Diffusers (ADV / ADVB / ADVR / ADVS / ADVL)
• Face Size: 24" (600 mm) square
• Inlet Sizes: 6", 8", 10", and 12" round
• Construction: 22-gauge steel housing with powder-coated finish and aerodynamic damper

• Thermostat is located inside the diffuser, removing the need for a wall-mounted thermostat.
• Positive induction draws a continuous sample of room air over the built-in sensor for accurate temperature measurement.
• Room setpoint is controlled by the building automation system (BAS) while the diffuser controls local airflow to maintain that setpoint.
• Ideal for open offices, glass walls, or spaces where wall thermostat placement is difficult or undesirable.

• A room temperature sensor provides constant feedback to a microprocessor controller mounted at the diffuser.
• The controller uses room temperature, duct/supply temperature, and setpoint to modulate the low-voltage damper motor.
• PI (Proportional + Integral) control algorithms provide stable room temperature without hunting or overshoot.
• Electric damper design maintains outlet velocities as the unit modulates, so throw and mixing remain consistent across the range.

• Maintains room setpoint with accuracy of approximately ±1 °F, improving occupant comfort.
• Immediate response to small changes in load conditions through direct digital control and direct-drive motor.
• Can be used as a standalone comfort solution or integrated to a BAS (with optional BACnet interface on the Advantage family).
• Supports auxiliary heat control to perimeter devices like baseboards or radiant panels when used with appropriate options.

• Power Module (APM): Central 24 VAC power for multiple Advantage diffusers.
• Pressure Relief Collar (ARC): Bypass collar to relieve excess static into the ceiling plenum.
• Pressure Independence Module (PIM): For pressure independent operation under varying upstream static.
• DMS Flow Measurement: Diffuser Measuring Station option for CFM measurement and BAS reporting (with BACnet).
• BACnet Interface: Optional interface to share room temperature, setpoint, and load with a BAS.

ADVB shares the same aerodynamic damper and digital control platform as the ADV, with the added benefit of a built-in thermostat to simplify installation and preserve architectural aesthetics.
