Product Description
RainBird ESP-2WIRE Controller Decoder 2W-1
Rain Bird’s controller lineup has been expanded to offer an entry-level, easy to use irrigation controller for
residential and light commercial applications. The ESP-2WIRE Controller will accommodate up to 50 stations
plus master valve/pump start relay and is suitable for indoor or outdoor applications. The ESP-2WIRE Controller
provides flexible scheduling features to accommodate a wide variety of landscape applications. Powerful
advanced irrigation features help meet any type of regional watering restrictions.
EASY TO USE AND INSTALL:
The ESP-2WIRE Controller features decoder auto-address for the controller to detect decoder addresses
that are connected to the 2-wire path and automatically assign them to station numbers for significant
time savings.
The ESP-2WIRE Controller is compatible with standard direct burial wire between 18 AWG (0.75mm²) and 10
AWG (6.0 mm²) and standard weatherproof irrigation wire connectors. To further simplify installation, there is
a grounding lug provided at the controller and field grounding the 2-wire path is not required. Although not
required, grounding the 2-wire path is possible with the use of the IVM-SD.
The ESP-2WIRE Controller mounts with as few as two mounting screws. A guide for 1/2” or 3/4” conduit fittings
allows for professional installation of field wires into the cabinet. For larger field wire needs, remove the knockout
for a 1” diameter opening.
