Use the table below to determine the best Irrigander expander or combination of expanders for your application. Note that this table is for a set of field wires running to a particular set of valves. There can be other sets of valves in the system. One connection to the Irrigander expander Decoder is the irrigation controller common connection. The common connection can be shared between the valves controlled by an Irrigander expander and valves not controlled by an Irrigander expander. See the application note "Configuring V2.x Irrigander Systems" for more information on installing Irrigander expanders. This application note is available in the Support section of our web site. Please contact our team if you have any application questions. They will be happy to help determine the best configuration of Irrigander expanders to provide a solution to meet your needs.
