OptiFlex BACnet building controller serves as a key component in the WebCTRL building automation system. It features built-in routing and integration capabilities, along with support for as many as nine expansion modules and 180 input/outpoint (I/O) points. The building controller is the latest addition to the OptiFlex line of flexible, scalable building controls. The product can control multiple pieces of HVAC equipment simultaneously while supporting complex building-control strategies. The HVAC equipment can then be managed from any web-enabled device using the WebCTRL building automation system, which provides operators with a set of online tools so that they can monitor equipment health in real time.
