Controllers with pump start/master valve and no sensor
terminal:
To Valves
Common Wire From Valves
Disconnect all common wires from the common terminal(s) and join
them to either RainSensor control wire using the supplied wire
connector. Be sure to include the common wire from the pump start
relay or master valve in this connection. Connect the remaining
RainSensor control wire to the valve common terminal.
Operation
Testing the Installation
To test the RainSensor operation, turn on a watering zone which is
visible from the RainSensor location.
Note: The manual activation cycle of some controllers bypasses
the sensor inputs. If the RainSensor is connected to the sensor ter-
minals, you will need to run an automatic/timed watering program
for these types of controllers.
With the sprinklers on, manually activate the RainSensor by press-
ing and holding the Test Spindle at the top of the unit. The sprin-
klers should shut off within a short time. If they do not shut off,
recheck the wiring connections at the controller. If the controller has
a sensor control or bypass switch, make sure the switch is set to
the position that will enable the sensor circuit to be active.
Normal Operation
When the RainSensor activates due to sufficient rainfall, the sprin-
kler system will become inactive until the moisture-absorbent discs
inside the RainSensor have dried out. The rate at which the discs
dry out will vary dependent on temperature, sun exposure, humidity
and wind— the same conditions your soil experiences. This allows
the RainSensor to reset when watering is needed again, enabling
the sprinkler system to resume normal operation.
