Johnson Controls Metasys

Historically, a Building Automation System (BAS) adds monitoring and control features to heating, ventilation, and cooling (HVAC) systems. Today, some BASs can also integrate with other building systems such as lighting, blinds, security, fire, etc. These BASs can be used to save energy by allowing users to monitor system parameters, identify faults, and implement schedules/programs.

Johnson Controls Metasys

The Johnson Controls Metasys Building Automation System solution consists of the Launcher/System Configuration Tool control software and a range of building controllers, general controllers and application specific controllers. This programable system integrates with HVAC and other building systems using a combination of open communication protocols and proprietary protocols.

Hub Highlights:

BACnet (IP & MS/TP) and N2 communication options between SNC-25151 building controller and lower-level controllers
REST Application Programming Interface (API)
Cyber security features include FIPS 140-2 and BACnet Secure Connect for data encryption
I/O ports built-in-to SNC25151building controller with optional I/O expansion modules
Manufacturer direct procurement, installation, commissioning, training, checkout and service contract
