LC-ZEC510-1 Johnson Controls Verasys

Overview

The LC-ZEC510-1 is a Verasys VAV Zone Controller designed by Johnson Controls for precise terminal unit management in light commercial HVAC systems. As part of the Verasys Smart Equipment family, it runs a pre-engineered HVAC zoning sequence that simplifies installation and provides the inputs and outputs required for VAV applications. The controller features an integrated damper actuator and seamlessly connects with building automation protocols using plug-and-play technology to automatically detect network sensors.

Features

• Plug-and-Play Technology: Automatically detects connected NS series network sensor types upon installation.
• Occupancy Sensing Capability: Supports an optional occupancy feature to transition from occupied mode to standby mode based on zone activity.
• Energy Efficient Standby Mode: Maximizes energy savings by using setpoints that are higher and lower than occupied mode setpoints.
• Carbon Dioxide Demand-Controlled Ventilation (CO2 DCV): Regulates zone CO2 levels by adding fresh air during occupied times.
• Versatile Reheat Sequences: Supports all fan types and provides staged, incremental, or modulating/proportional SCR box heating outputs.
• Data Retention: Equipped with non-volatile flash memory to preserve configuration data and operating parameters during power cycles.

Specifications

• Power Supply: 20 VAC to 30 VAC at 50 Hz to 60 Hz, Class 2 power supply or safety extra-low voltage (SELV).
