Wireless Mini-Clik Sensor - Operation

Receiver Operation
The receiver has two LED lights that indicate the state of the system.
RED: Sensor is wet (watering disabled)
GREEN: Sensor is dry (watering enabled).
YELLOW: Sensor is in addressing mode.
RED: Rain sensor is bypassed (The STATUS LED will continue to alert you of the state of the sensor — wet or dry).
GREEN: Rain sensor is enabled.
YELLOW: Indicates that communication between the transmitter and receiver was lost.

NOTE: When you first apply power to the receiver, the SENSOR STATUS LED will be RED. Press the manual test spindle on the transmitter for five seconds and release the spindle. The SENSOR STATUS LED will turn GREEN indicating proper operation.

Transmitter Operation
The Wireless Mini-Clik Sensor keeps the irrigation system from starting or continuing after receiving rainfall quantities of ⅛" (3 mm), ¼" (8 mm), ½" (13 mm), and ¾" (19 mm). To adjust it to the desired shutoff quantity, rotate the cap on the switch housing so that the pins are located in the proper slots. Do not forcibly twist the cap, as this could break the pins.
The time that it takes the sensor to reset for normal sprinkler operation after the rain has stopped is dictated by weather conditions (e.g., wind, sunlight, humidity). These conditions will determine how fast the hydroscopic discs dry out. Since the turf is also experiencing the same conditions, their respective drying rates will roughly parallel each other. This means when the turf needs more water, the sensor is already reset to allow the sprinkler system to run at the next scheduled cycle.

NOTE: Once the desired rainfall quantity has been set, it is recommended that the settings do not change for the entire use of the sensor as the hydroscopic discs become accustomed to the first setting chosen after the first rainfall event. It is unlikely the hydroscopic discs will respond to a new setting which may prevent irrigation from shutting down when expected.
