The Verasys from Johnson Controls is designed as a plug-and-play controls system that integrates heating, ventilation, air-conditioning, and refrigeration (HVACR) equipment and controls. Verasys offers a one-source procurement solution with advanced technology already embedded for the self-discovery of Smart Equipment. Suitable for single- or multi-zone applications, the controls system connects to a vast range of mechanical and electrical equipment, controls and sensors using wireless configurations. The system communicates using BACnet MSTP. The control system also has equipment servicing capabilities with optional fault detection and diagnostics that immediately deliver alarm notifications via email or text. For building operators Verasys provides remote access over a secure internet connection using PCs, smartphones, and tablets. The controls system connects users to data streams from smart controls in rooftop units, fan coils, zone dampers, heat pumps, refrigeration systems, lighting panels, and more. With real-time data, building operators can identify and troubleshoot issues remotely.
