75F Central Control Unit (CCU)
The 75F Central Control Unit (CCU) is the on-site brain of the 75F platform: a wall-mounted tablet, building management interface, and gateway to the 75F cloud. It aggregates zone data from 75F terminal devices, makes AHU control decisions, and provides a modern touchscreen for facility teams.

Description
Product Overview
- Model: 75F Central Control Unit (CCU)
- Function: Wireless building management hub and AHU/rooftop supervisor
- Interface: 8" 1200 × 800 touchscreen tablet with Android-based UI
- Role: Connects 75F Smart Nodes, HyperStats, and sensors to the 75F cloud and coordinates system-level control.
How It Works
- Communicates with field devices over a secure 900 MHz mesh network and RS-485 for Modbus devices.
- Uses Wi-Fi or LAN to connect to the 75F cloud, enabling proactive and predictive control strategies.
- Aggregates zone-level data (temperature, occupancy, airflow, etc.) to optimize AHU and equipment operation.
- Supports operation with or without an active cloud connection, maintaining core control locally.
Key Features
- Controls single and multi-stage systems, heat pumps, fan coils, air handlers, and more.
- Supports up to 48 terminal equipment modules per CCU for scalable deployments.
- Built-in scheduling, setpoint adjustments, and live trend graphs on the touchscreen interface.
- Alerts and events with severity color coding for quick diagnostics.
- Removable tablet with secure magnetic alignment and locking slider for easy service.
The CCU combines the role of a traditional supervisory controller and an applied equipment controller in one device, simplifying architecture while enhancing visibility for owners and operators.
