Built-In Diffuser Thermostat

• Thermostat is located inside the diffuser — no wall-mounted thermostat required.
• Positive induction draws a continuous sample of room air over the built-in sensor for accurate measurement.
• Room setpoint is controlled by the 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.

Comfort & Control Features

• Maintains room setpoint with accuracy of approximately ±1 °F, improving occupant comfort.
• PI control algorithms provide stable room temperature without hunting or overshoot.
• Optional BACnet interface (Advantage family) allows sharing of room temperature, setpoint, and load with a BAS.
• Supports auxiliary heat control to perimeter devices like baseboards or radiant panels.

Accessories & Options

• APM: Central 24 VAC power for multiple Advantage diffusers.
• ARC: Bypass collar to relieve excess static into the ceiling plenum.
• PIM: Pressure independence module for varying upstream static.
• DMS: Diffuser Measuring Station for CFM measurement and BAS reporting.
• BACnet Interface: Optional interface to share room temperature, setpoint, and load with a BAS.
