Information About W7751H2025
The W7751H2025 is part of Honeywell’s VAV II controller family, engineered to serve as an integrated actuator and control module for variable air volume terminal boxes. Its construction features a compact housing paired with an ML6161 actuator mounted directly on the damper shaft, reducing installation time and wiring complexity. This controller communicates over a LonWorks bus and is fully compatible with Honeywell commissioning tools such as CARE, LonSpec, RapidZone, and LNS plug-ins. It is commonly used in commercial HVAC systems requiring pressure-independent airflow control and utilizes PID temperature control, airflow sensing, and programmable heating sequences to optimize zone performance.
Key Features:
- Integrated actuator assembly: ML6161 actuator mounts directly on the VAV box damper shaft.
- LonWorks communication: Supports networked control via standard LonWorks bus.
- Multiple output modes: Provides PWM, floating, and staged on/off outputs for heating control.
- Wide environmental ratings: Operates from 0–50 °C and 5–95% non-condensing humidity.
- Pressure-independent VAV control: Uses microbridge airflow sensing for accurate volume regulation.
- UUKL fire system approval: Suitable for use in compliant life-safety HVAC applications.
- Factory-configured defaults: EEPROM stores critical operating parameters for quick deployment.
- Flexible commissioning: Supported by CARE, LonSpec, RapidZone, and LNS plug-in software.
The W7751H2025 delivers the reliability and precision required for advanced VAV zone control in commercial HVAC systems.
