Honeywell W7751H 2025 Smart VAV Actuator handheld pcs accessory

SKU CH-GCMG-G4XZZ MPN W7751H

Smart VAV actuator operates at 50 Hz or 60 Hz with 78 kilobit LonWorks bus communication

  • Smart VAV control with LonWorks bus integration
  • Dual-frequency operation at 50 Hz and 60 Hz
  • High-speed 78 kilobit network communication
  • Wide setpoint range from 7 to 37 °C
  • UUKL-approved contact ratings for safety compliance

Smart VAV actuator for building controls

The Honeywell W7751H 2025 is a smart VAV actuator designed for integration into Excel 10 building automation networks. It communicates over a Lon Works Bus at a high-speed rate of 78 kilobit and operates on either 50 Hz or 60 Hz power supplies. The unit includes the ML6161 actuator and carries UUKL approval for life-safety applications.

Installers commissioning LonWorks zones

This device suits technicians commissioning variable-air-volume zones using the LonSpec RapidZone LNS plug-in and application 63-7045. It supports setpoint temperatures from 7 to 37 C (45 to 99 F) and humidity ranges of 5 to 95% RH non-condensing. Buyers needing BACnet or Modbus compatibility should look elsewhere, as this actuator uses LonWorks exclusively.

LonWorks bus speed determines network fit

The single specification that decides fit is the 78 kilobit LonWorks communication speed. Controllers and routers on the same segment must match this rate for reliable data exchange. Verify that the existing trunk supports high-speed Lon operation before selecting this actuator.

Questions about this item

Does the 50 Hz, 60 Hz 78 kilobit LonWorks bus actuator generate noticeable noise or heat during continuous daily operation?

The Honeywell W7751H 2025 Smart VAV Actuator operates on a 50 Hz, 60 Hz 78 kilobit LonWorks bus with the included ML6161 Actuator, designed for quiet, low-heat performance inside VAV terminals.

What existing building-automation infrastructure must be in place for this LonWorks bus actuator to function?

A LonWorks network running the 63-7045 application and the LonSpec RapidZone LNS Plug-in commissioning software is required to configure and operate the actuator.

Will this 78 kilobit LonWorks bus actuator integrate with older Excel 10 controllers already on the same bus?

Yes, the W7751H 2025 communicates at 78 kilobit over the same LonWorks bus used by Excel 10 devices, allowing mixed-generation zoning without bus-speed changes.
