Heron Ti-240 three-output decoder (DEC-B3) for a compatible Heron Ti-240 two-wire irrigation-control system. It provides three field outputs for controlling up to three compatible 24 VAC solenoid valves.

Use it where multiple valves are to be controlled from one decoder location on the Ti-240 two-wire path. The decoder must be addressed and commissioned within a compatible Ti-240 system. Not for conventional multi-wire controllers.
