Sensor connection and operation:
To connect a rain sensor, remove the jumper wire from the sensor terminal and
connect one wire of the Toro Rain Switch to the C-common terminal and the other
wire to the N.C. (normally closed) terminal. As soon as the Rain Switch contacts
change from the N.C. position to the N.O. (normally open) position, irrigation will
be suspended. Irrigation will resume as soon as the Rain Switch dries and its
contacts return to the N.C. position.
When irrigation is suspended due to the Rain Switch, the display shows: OFF
NOTE: When using the Toro Rain Switch, follow the Basic Connection
Installation Instructions.
