FEATURES...................................................................................

Wireless Rain-Clik™ sensors attach quickly and easily to your controller. Wireless Rain-Clik™ features include:

•Quick Response™ unique technology that turns off the irrigation system immediately – not after it has accumulated a fixed amount of rain. No calibration is required.

•Maintenance-free design provides trouble-free operation for up to ten years. There are no batteries to replace.

•Wireless operation up to 800 ft. (275m)

No wires are required between the rain sensor and controller.

•Two models available:

Wireless Rain-Clik™ (WR-CLIK) acts as a switch to deactivate automatic watering of your irrigation controller when it rains. Once rain has stopped and the sensor has dried out, automatic

irrigation will resume.

Wireless Rain/Freeze-Clik (WRF-CLIK) the Wireless Rain/Freeze-Clik includes a freeze sensor that is designed to keep the irrigation system from operating when temperatures drop to 37˚F or below. When temperatures rise above 37˚F, the sensor will enable automatic watering.

•Automatic Synchronization – the Wireless Rain-Clik™ transmitter will send wireless signals every hour to the receiver to assure that the sensor and receiver are continuously synchronized.

•Lost Communication/Battery Status Indication – the Sensor Bypass LED will flash RED if the receiver has not received a signal from the transmitter. This can indicate a low or dead battery.

WIRELESS RAIN-CLIK™ COMPONENTS...............................

Wireless Rain-Clik™ Transmitter

1.Manual Test Spindle – press and hold the manual test spindle to confirm proper operation of your transmitter.

2.Vent Ring – used to adjust the reset rate or dry out time for the sensors. Opening the vents will decrease the reset rate, while closing the vents will increase the time it takes for the discs to dry out.

3.Radio Antenna – transmits a wireless signal to the receiver up to 800 ft. (275m) It is recommended that the antenna be oriented

		vertically.		4
	4.	Mounting Arm –
		metal extension arm
		for mounting the

Wireless Rain-Clik™ Receiver

1.Bypass Button – allows automatic or manual watering when the sensor is active.

2.Sensor Bypass LED – indicates when sensor has been bypassed.

3.Sensor Status LED – used to indicate the status of the sensor.

4.Radio Antenna – receives a wireless signal from the transmitter up to 800 ft. (275m) It is recommend that the antenna be oriented vertically.

5.AC Power Wires – the two yellow wires are attached to a 24 VAC source from the controller.

6.Sensor Wires (See page 5) – the sensor wires are attached to either the sensor terminals in the controller or in-line with the valve common wire.

Blue/White Wires (used for normally closed sensor applications)

Blue/Orange Wires (used for normally open sensor applications)

7.Rubber Cover – used to protect the receiver when mounted in outdoor locations.
