RainSensor Operation
Normal Operation
When the RainSensor activates due to sufficient rainfall, the Sensor Status Indicator
will remain illuminated on the Receiver and the sprinkler system will remain inactive
until the moisture-absorbent discs inside the Sensor/Transmitter have dried out. The
rate at which the discs dry out will vary dependent on ambient conditions such as
temperature, sun exposure, humidity and wind— the same conditions your soil experi-
ences. This allows the Wireless RainSensor to reset when watering is needed again,
enabling the sprinkler system to resume normal operation.
Smart Bypass
Your Wireless RainSensor can be temporarily deactivated by using the built-in Smart
Bypass button. Simply press this button once to bypass current RainSensor control.
The Sensor Status light will blink until the next time the Sensor/Transmitter dries out
and automatically resets. Pressing the Smart Bypass button again resumes the
RainSensor control. Pressing the Smart Bypass button while the RainSensor control is
not active (dry) will cause the Receiver to ignore the next Sensor/Transmitter signal.
Power Down
To turn the Receiver OFF entirely, press and hold the Smart Bypass button until the
Sensor Status Indicator begins blinking rapidly (5–7 seconds). Release the Smart
Bypass button and confirm the Power Indicator goes out and flashes periodically.
Simply press the Smart Bypass button once to turn the Receiver back on.
Receiver Learn Mode
If it becomes necessary to set the Receiver’s address code to that of a new
Sensor/Transmitter, press and hold the Smart Bypass button until the Status and
Signal indicators blink in unison (10+ seconds). Activate the corresponding
Sensor/Transmitter at close range (by pressing down on the Test Spindle) to change
the existing Receiver code to that of the new Sensor/Transmitter. The indicators will
stop blinking upon learning the new code. Pressing the Smart Bypass button again
will exit the learn mode if no valid code is received.
Attention Required
When the Power Indicator blinks, it indicates that either of the following conditions
exists:
•
The Sensor/Transmitter’s battery is getting low and should be replaced when con-
venient. The Wireless RainSensor will function properly for some time after this indi-
cator is present. Refer to “Sensor/Transmitter Battery Replacement” on page 10.
•
If the batteries are good, a problem with communication is indicated. Relocating the
Sensor/Transmitter may be necessary to provide a better signal. Refer to “Solving
Reception Problems” on page 10.
