Description
Product Overview
- Model: 75F Smart Node
- Function: Terminal box/zone controller with software-defined configurations
- Applications: VAV/VVT boxes, bypass dampers, economizers, single-zone units, unit heaters, exhaust fans
- Interface: Onboard LED display with navigation buttons for local verification and setup
How It Works
- Powered by 24 V AC/DC, with the ability to daisy-chain power along a bus for multiple nodes.
- Pairs to the CCU over Bluetooth, then loads pre-written sequences of operation from the cloud.
- Communicates over 75F’s secure 900 MHz mesh network, minimizing the need for network cabling.
- Optional built-in differential pressure sensor supports CFM-based VAV control (different part number).
Key Features
- No custom programming required — select a sequence, set a few parameters, and go.
- Tool-less WAGO-style push-in connectors and magnetic cover for fast installation and service.
- Automatic over-the-air updates keep logic and sequences up to date.
- Supports both wireless mesh and wired RS-485 (Modbus/BACnet, sensor bus, PoR for sensors).
Smart Node is the core field controller in the 75F ecosystem, delivering advanced terminal control with a streamlined, installer-friendly workflow.
