5.5 Sensor
The irrigation controller offers advanced
irrigation control using a rain off sensor. That
is, as long as the conditions defined for
activation of the sensor are not met, the
irrigation schedule will not be implemented.
(The rain off sensor contact remains closed).
For example, if a rain sensor is connected to
the irrigation controller, irrigation takes place
as long as the sensor remains dry. In the
event of rainfall, the sensor prevents the
opening of all the valves associated with it.

There is also the option of using any type of
dry contact sensor N.O. When the sensor
contact is closed all valves will close and no
irrigation will take place (diagram page 6).
As long as the sensor closes the circuit (i.e.,
the sensor detects the existence of a defined
program lockout condition) the symbol blinks
on the display and irrigation will not take place
through any valves associated with the sensor.
The display will show “S OFF” when the
controller is in manual operation. This means
the sensor is activated and prevents the
irrigation.
