They are best suited for use with a GTI Gemini PC or EC system as the combination of Gemini controller and decoders will give the user consistent and reliable irrigation for many years.
Gemini decoders can be installed prior to replacing the controller, at the same time, or after the controller has been installed. This allows a site wishing to upgrade from an older Watermation TW2 to gradually replace Watermation MK1, MK2 and 3rd party replacement or replica TW2-based decoders.
By replacing faulty Watermation and 3rd party replica decoders with GTI Gemini decoders, your irrigation programs will be shortened dramatically, provided the installed hydraulics can cope with the additional demand.
