Hunter A2C-F3 ACC2 3-Input Flow Expansion Module

The Hunter A2C-F3 3-Input Flow Expansion Module adds three additional flow sensor inputs to ACC2 controllers, enabling more precise flow monitoring and automated response for commercial and large-scale irrigation systems. Purpose-built for field reliability, the module extends the controller's native flow capabilities and integrates directly with ACC2 programming menus for straightforward setup.

• Expanded flow capacity: Adds three flow sensor inputs, expanding ACC2's total flow inputs to six for broader system coverage.
• Simple installation: Installs in the lower-right module slot; only one A2C-F3 module fits in this position and it mounts quickly with slide locks.
• DC-polarity inputs: Flow inputs are DC with polarity — connect the red lead to the positive terminal to ensure correct operation.
• Controller configuration: Finish flow expansion in the ACC2 Devices → Flow Sensors menu; the controller supports flow zones and real-time monitoring.
• Commercial-grade monitoring: Enables leak detection, flow-based event response, and tighter water management when paired with compatible flow meters.

Refer to the Hunter ACC2 installation and service documentation for wiring diagrams, fuse specifications, safety precautions, and compatibility notes. The A2C-F3 is a purpose-built expansion for ACC2 controllers and should be installed and configured by qualified irrigation technicians.
