The Schneider Electric Cooling Only LonMark VAV Controller MNL-V1RV3-2 is a LonMark-certified, single-duct cooling-only variable air volume terminal unit controller designed to regulate room temperature by modulating VAV box airflow in commercial building HVAC systems.

• Part Number: MNL-V1RV3-2
• Protocol: LonWorks (LON TP/FT-10), LonMark certified
• Control: Cooling only, single-duct VAV
• Damper Control: 0-10V analogue or floating point to actuator
• Room Sensor Input: Compatible with MN series sensors
• Power Supply: 24 VAC
• Compatible System: Schneider TAC Vista, third-party LON BAS

Deployed on interior-zone VAV terminal units in commercial office buildings, schools, and retail stores where perimeter heating is provided by a separate system (baseboard heaters, radiators) and the VAV box only modulates cooling airflow.

LonMark certification guarantees interoperability with any third-party LON supervisor platform. Controls zone temperature by adjusting damper position from minimum ventilation position to full open based on PID control algorithm.
