Features
Wireless Rain-Clik sensors attach quickly and easily to
your controller.
Wireless Rain-Clik features include:
1. Quick Response® – Unique technology that turns o
the irrigation system immediately rather than aer it
has accumulated a xed amount of rain. No calibration
is required.
2. Maintenance-Free Design
– Provides trouble-free
operation for up to 10 years. There are no batteries to
replace.
3. Wireless Operation Up to 800' (275 m)
– No wires are
required between the rain sensor and controller.
4. 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.
5. 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 (3˚C) or below. When
temperatures rise above this temperature, the sensor
will enable automatic watering.
6. Automatic Synchronization – The Wireless Rain-Clik
transmitter will send wireless signals every hour to
the receiver to ensure that the sensor and receiver are
continuously synchronized.
7. Lost Communication/Battery Status Indication – The
Sensor Bypass LED will ash RED if the receiver has not
received a signal from the transmitter. This can indicate
a low or dead battery.
