Two-wire leg connections and rules
Last Updated: January 20, 2023The output of the HSC wire paths is 24VAC, 50/60 Hz. Voltage is only present on the legs when stations are active. There is no polarity on the Hydro-Rain decoder system. Use direct burial-rated irrigation wire. The size of the wire determines the effective distance of the two-wire path. See the wiring table for distance...
Understanding 2-Wire Decoder Systems
Last Updated: January 19, 2023Overview Imagine fifty people who have to get to the same place, each driving their own car. This scene represents the expense of the wire and labor for a conventional installation, with a separate wire running to each valve. Now, imagine if they could all take a bus. The bus makes a stop near each...
