Claim of US Patent No. 9,081,376

1. A module for insertion into an irrigation controller, the module comprising:
a micro-controller for receiving communications commands from a processor of the irrigation controller;
a plurality of push buttons operatively connected to the micro-controller for identifying and programming a plurality of decoder
circuits connected to a multi-wire path;

a display operatively connected to the micro-controller for enabling a user to identify and program the decoder circuits;
and

driver circuitry operatively connected to the micro-controller for sending encoded signals and an AC power signal along the
multi-wire path, the module configured to insert into the irrigation controller connectable to the multi-wire path for sending
the encoded signals and the AC power signal along the multi-wire path for selectively energizing one of a plurality of solenoid
actuated valves connected to corresponding decoder circuits connected along the multi-wire path.
