HOW THE SENSOR FEATURE WORKS

The Custom Command is equipped to operate with an optional rain
sensing device, commonly called a "Rain Switch," to prevent
automatic watering during rain.
The rain switch is a simple device, typically installed on a roof
overhang or stationary structure exposed to rainfall and full sun, and
shielded from irrigation spray.
When rain occurs, the normally closed rain switch senses the moisture
and opens the valve common circuit, effectively preventing all output
to the field. The electronic programming portion of the controller is
isolated from the rain sensor switch, and continues to operate as
programmed. When rain stops and the rain switch returns to its
normally closed state, the valve common circuit is restored, enabling
watering to resume as scheduled.
A two-position Sensor switch (see item 19 on page 3) is provided to
enable you to easily bypass operation of the rain switch at any time. If
you choose to disregard rain switch input, place the switch in
SENSOR
the position. To enable rain switch operation, place the Sensor
Bypass
switch in the position.

Note: A jumper wire is installed across the sensor terminals. The
jumper must be removed when the rain switch wires are connected.
