LC-BYP200-0 Johnson Controls Verasys Damper Controller

Overview

The Johnson Controls LC-BYP200-0 is a field-installed bypass damper controller designed as a component of the Verasys and Commercial Comfort System (CCS) zoning families. It runs a pre-engineered HVAC change-over bypass application to provide precise environmental control in light commercial building automation setups. It features advanced operating sequences to maintain occupant comfort and optimize system pressure management.

Features

• Pre-engineered zoning software simplifies setup without the need for custom programming.
• Seamless integration with the Verasys system for building automation control.
• Designed for field installation directly onto standard zone or bypass damper assemblies.
• Advanced standby modes maximize energy savings during unoccupied hours.
• Direct-mount capabilities with single-screw attachment to simplify installation.

Applications

The LC-BYP200-0 is utilized in commercial comfort HVAC systems to control bypass dampers within a zoning network. It automatically manages duct static pressure by bypassing excess air supply back into the return ductwork, ensuring stable pressure and optimal airflow as individual zone dampers open and close throughout a building.
