HVAC Zone Control Solution – Honeywell CLLYVB6436AS-VAV | VAV Series
The Honeywell CLLYVB6436AS-VAV is a high-performance BACnet-native Variable Air Volume (VAV) zone controller engineered for precision airflow and temperature management in commercial and industrial HVAC systems. Designed for demanding environments where occupant comfort, energy efficiency, and system reliability are non-negotiable, this controller integrates seamlessly into modern Building Automation Systems (BAS).
Where This Product Is Used
The CLLYVB6436AS-VAV is specified by mechanical engineers and BAS integrators across a wide range of applications:
- Commercial Office Buildings – Multi-zone VAV systems requiring independent room-level temperature and airflow control with BACnet MS/TP network integration.
- Hospitals & Healthcare Facilities – Critical environment control where precise air changes per hour (ACH) and pressure relationships must be maintained 24/7.
- Pharmaceutical & Cleanroom Environments – ISO-classified spaces demanding tight differential pressure and airflow stability for regulatory compliance (GMP, FDA 21 CFR Part 11).
- University & Research Laboratories – Fume hood exhaust tracking and supply air coordination in variable-occupancy lab spaces.
- Data Centers & Server Rooms – Precision cooling zone management to protect sensitive IT infrastructure from thermal excursions.
- Retail & Hospitality – Energy-optimized comfort control across large open-plan or multi-room commercial spaces.

Application-Specific FAQ
Q: Is the CLLYVB6436AS-VAV compatible with Niagara N4 (Tridium)?
A: Yes. As a native BACnet MS/TP device, it integrates with any BACnet-compliant supervisor including Niagara N4, Honeywell WEBs-AX, and Siemens Desigo CC without requiring a protocol gateway.
Q: Can this controller handle reheat applications?
A: Yes. The CLLYVB6436AS-VAV supports both hot water reheat coil control (via floating or modulating output) and electric reheat staging, making it suitable for perimeter zone and interior zone applications.
Q: What is the maximum number of VAV controllers per BACnet MS/TP segment?
A: BACnet MS/TP supports up to 127 devices per segment. For large projects, multiple segments can be connected via a BACnet router or IP backbone.
Q: Is this product suitable for cleanroom or pharmaceutical use?
A: Yes. The controller’s precise airflow modulation and pressure tracking capabilities make it well-suited for ISO-classified cleanrooms and GMP manufacturing environments where regulatory airflow compliance is mandatory.
Q: What programming tool is required for commissioning?
A: The CLLYVB6436AS-VAV is typically commissioned using Honeywell’s WEBs Engineering Center (WEC) or compatible BACnet commissioning tools. Pre-configured application programs are available for standard VAV sequences of operation.
