Johnson Controls Metasys and Facility Explorer are the flagship building automation platforms used across millions of square feet of commercial, healthcare, education, and industrial facilities. TCI Supply supports the buildings running on these systems by stocking the replacement controllers, VAV zone modules, network engines, power supplies, and legacy 9100-series modules needed to keep BAS networks operating.
Whether your facility is on a full Metasys campus network or a smaller Facility Explorer installation, we can source the correct field equipment controller, network expansion module, or replacement power supply. Our team handles same-day quotes on both current and end-of-life BAS hardware.
Johnson Controls (JCI) Metasys and Facility Explorer BAS controllers drive the automation intelligence behind complex air volume tracks, mechanical rooms, and enterprise campus networks. Because maintaining or expanding these DDC frameworks requires an absolute match of communication protocols (BACnet MS/TP, legacy N2, or N1), I/O point configuration profiles, and active firmware revisions, sourcing drop-in automation replacements can be a significant technical challenge. Contact our dedicated automation sourcing team today to locate your specific VAV controller, field equipment controller, network engine, or legacy 9100-series module.
We maintain an active, deep inventory of current network modules and deeply legacy, discontinued DDC field controllers. This enables engineering teams to maintain operational field bus continuity without being forced into prematurely executed or budget-breaking system migrations.
Variable air volume box controllers equipped with integrated I/O loops for precise airflow measurement, damper positioning, and reheat control. Communicates over standard BACnet MS/TP field buses.
Higher-end VAV zone controllers featuring expanded I/O density and advanced, sophisticated localized control logic. Dual-protocol compatible across legacy N2 and modern BACnet field buses.
Fully programmable Metasys field controllers engineered for custom building applications beyond basic zone service. Commonly deployed for complex chiller sequencing, air handler unit (AHU) control, and complete mechanical room integration.
Niagara-framework-based Facility Explorer controllers optimized for small-to-medium building automation infrastructure requiring robust, multi-protocol interoperability across third-party devices.
Older-generation network router and communications bridge that maps legacy Metasys N1 or N2 field buses cleanly onto modern high-speed Ethernet network backbones.
Long-serving, foundational Metasys DDC field controllers, hardware expansion modules, and terminal boards. Maintained heavily in our stock specifically to keep vintage, functional control loops running reliably.
Industrial 24 VDC power supply modules engineered for clean, stabilized power distribution across field devices, logic buses, and system controller cards.
Metasys system controllers leverage a structured positional catalog numbering sequence that maps out system series generation, hardware platform, point density, and exact assembly sub-types. Review our technical breakdowns below.

Metasys VAV Controller Replacement Tip: When sourcing a replacement VAV modular assembly like the MS-VMA1620-0, it is crucial to verify both the catalog model code and the active internal firmware revision fixed to the existing module. Certain manufacturing generations of the VMA1620 utilize BACnet MS/TP communications natively, whereas older heritage revisions are restricted entirely to N2 protocol layers. Attempting to mix incompatible revisions on the same physical token-ring field bus will destabilize trunk polling and create severe commissioning loop errors. E-mail our engineering team a clear photo of your active hardware label for exact revision tracking.
Maintaining fine system environmental parameters and responsive BAS control loops requires a clear understanding of device interoperability, network failures, and modernization options. Review our technical hardware support answers below.
