The ACC2 Decoder is specifically engineered to work in tandem with Hunter ICD decoders. To enable their operation, station numbers must first be programmed into the ICD decoders.
In terms of functionality, the ACC2 Decoder closely resembles the conventionally wired ACC2 controller, but it also incorporates a Decoder menu that provides access to all of the unique decoder functions and diagnostics. Additionally, certain devices such as Pump/Master Valves and sensors can be assigned to decoder locations, and the individual setup screens now include this option.
