Web Enabled Controller

Access and control your facility easily and cost-effectively from the internet using the Reliable Controls MACH‑ProWebSys™ building controller. The unique three-in-one design of the MACH‑ProWebSys combines a BTL-listed BACnet Building Controller (B‑BC), a BACnet Operator Workstation (B‑OWS), and a powerful web server in a single package no larger than a typical controller. The built-in workstation reduces your capital expenditures by eliminating workstation client software, and the built-in web server reduces your operating expenditures by eliminating client license renewals and fees for cloud services. There is no software to download and no IT server to maintain. Every MACH‑ProWebSys can control hundreds of sensors and actuators using standard protocol networks. Backed by the industry-recognized Reliable Controls 5-year warranty and designed to remain backward compatible with previous-generation systems, the MACH‑ProWebSys provides lasting value for generations.
