54 ESP-LX+ & LXi+ Installation, Programming, & Operation Guide
Sensor System Wiring
NOTE: Complete this section only if your system has
an automatic rain sensor.
If you are not connecting a sensor to the controller,
make sure the supplied jumper is installed on the
two SENSOR terminals on the controllers vertical
terminal strip.
➊ Most sensors have two wires or two terminals designed to
be connected to the valve common wire. Instead of
connecting to the valve common wire, connect these wires
or terminals to the SENSOR terminals on the ESP-LX+ or
LXi+ controller.
➋ Route the pair of wires out of the controller cabinet to the
sensor system.
➌ Follow the sensor systems directions for placing and
connecting moisture probes, setting the rain shutoff level,
and making final adjustments.
