WeatherTRAK 2-Wire Single Station Decoder (H2O) Pre-Programmed

The valve decoder acts as a switching device that turns a valve on and off with a signal from the controller. Decoders are usually installed at the valve they control, in the same valve box. Valve decoders are available in two configurations: single valve decoders and dual valve decoders. A dual valve decoder can manage two valves independently which saves on material costs and installation time.
