Hunter ACC-99D 99-Station Two-Wire Decoder Irrigation Controller Brand: Hunter Industries | SKU: ACC-99D Product Overview The Hunter ACC-99D is a commercial two-wire decoder irrigation controller with capacity for up to 99 decoder stations. It is housed in an outdoor metal wall-mount cabinet and is intended for large landscapes where running a separate control conductor to every valve would be impractical. The controller communicates with compatible Hunter ICD field decoders over color-coded Hunter ID wire. Six two-wire output paths support distributed station and sensor decoders, and compatible two-way decoders allow the controller to confirm commands and report status information. Field decoders, ID wire, sensors, flow equipment, communication hardware, pedestal, and grounding components are selected separately. ACC-99D provides six automatic programs, 10 start times per program, flow-management capability when properly equipped, Solar Sync support, seasonal adjustment, Cycle and Soak, programmable rain delay, Easy Retrieve memory, alarm logs, and decoder-line diagnostics. This is a legacy ACC decoder controller and should not be confused with ACC2 conventional or ACC2 decoder hardware.
