LC-VZC100-0 Johnson Controls Verasys

Overview

The Johnson Controls LC-VZC100-0 Verasys Zone Coordinator is used for multi-zone HVAC applications as an engine to coordinate a complete VAV (Variable Air Volume) or COBP (Changeover Bypass) system. It automatically recognizes the unit configuration and switches to either VAV or COBP based on the system type. It can be used in conjunction with a Smart Equipment RTU, VEC100, BYP200/ZEC310 COBP, or ZEC510 VAV. The VZC resides on the system bus and provides a zone CS bus where all components of a multizone system reside.

Features

• Automatically recognizes unit configuration and switches to VAV or COBP mode based on the system type.
• Factory-configured to work with the Verasys ecosystem, minimizing setup and commissioning time.
• Selectable addressing using an 8-position DIP switch for MAC addresses.
• Features onboarding EOL (End-of-Line) termination switches for both System Bus and Zone Bus networks.
• Connects seamlessly to a Smart Building Hub (SBH) for advanced troubleshooting and user interface access.
• Available as either a board-only model or a pre-mounted enclosure version.

Specifications

• Input Power (Board-Only Model): Removable terminal plug for 24 VAC supply power and removable plug for 12 VDC supply power.
