Honeywell PUB4024S/U Spyder Micro BACnet Module

The Honeywell Spyder Micro BACnet (PUB4024S/U) is a programmable unitary controller from Honeywell/Niagara designed for building automation and HVAC control applications. As part of the Spyder Micro product family, it leverages the BACnet communication protocol to integrate with building management systems, enabling centralized monitoring and control of mechanical equipment such as air handling units, fan coil units, and terminal devices. Its compact form factor and BACnet-native architecture make it well suited for commercial and light-industrial environments where interoperable, standards-based control is a requirement. The PUB4024S/U is sourced as a genuine Honeywell/Niagara component, appropriate for new installations and replacement applications within existing Spyder-based control infrastructure.

Key features & benefits

• BACnet-Native Communication — Built on the BACnet protocol, the PUB4024S/U is designed to integrate directly into open, interoperable building automation networks without requiring proprietary gateways or middleware.
• Programmable Unitary Control — As a programmable unitary controller, it can be configured to manage a wide range of HVAC and mechanical plant equipment, adapting to application-specific sequences of operation.
• Genuine Honeywell/Niagara Lineage — Manufactured under the combined Honeywell/Niagara brand, the device is backed by the engineering heritage of both organizations in building controls and open-protocol automation platforms.
• Compact Spyder Micro Form Factor — The Micro designation within the Spyder family indicates a space-efficient physical footprint suitable for installations where panel space is limited.
