75F® Central Control Unit™

The on-site conductor for smart buildings

Cloud computing meets IoT inside smart buildings. The 75F^® Central Control Unit™ (CCU) acts as an aggregation gateway for the modules in the building. At the "head" of the local system, the CCU provides the primary on-site user interface for building management, complementing Web and mobile access. The CCU consists of a removable, custom tablet running Android and seated in a custom Control Mote (CM), with multiple wireless communications protocols, plus 8 wired relays and inputs/outputs for controlling HVAC, lighting and other building equipment.

The CCU interface provides cross-zone, zone-specific and equipment-specific status, real-time data graphs, and a robust set of settings and software-defined configuration capabilities through an intuitive graphic user interface.

The CCU replaces a standard thermostat and connects to the low voltage relay contacts that activate the controlled system. The user interface is upgraded remotely to accomplish new function releases.

Communications, connectivity & control

The CCU is a combination of a custom Android tablet and control mote backplate serving as the central gateway for communications and control for all 75F product solutions and applications. The CCU provides an on-site, wall-mounted user interface to complement the included 75F Facilisight^® web and mobile app software. The CCU works with single and multi-stage systems, heat pump systems, fan coil units, air handlers and variable flow hydronic systems.

Wireless Communications Protocols

WiFi for cloud data sync, predictive algorithmic processing and access through the 75F Facilisight software suite via desktop or mobile app
Optional cellular modem as alternative to WiFi connectivity
2.4 Ghz Bluetooth for easy pairing, commissioning and near-field communications with wireless devices
900 Mhz Wireless mesh network provides communications across modules for system functionality, even in event of Internet outage

The 75F Smart Node includes 16 interface ports to support a wide range of I/O uses that support unlimited applications.
