Wireless RainSensor Operation
Normal Operation
When the Wireless RainSensor activates due to sufficient rainfall or freezing tempera-
tures (model RFS1000 only), the Sensor Status indicator will remain illuminated on the
Receiver. After the rain sensor dries out, the controller will resume its normal watering
schedule and the Sensor Status Indicator will turn off. The amount of rain required to
activate the sensor can be set using the cap adjustment on the Sensor/Transmitter.
Dry-out rates for the rain sensor vary dependent on ambient conditions such as
temperature, sun exposure, humidity and wind – the same conditions your soil
experiences.
Smart Bypass
Your Wireless RainSensor can be temporarily deactivated (if in active state) by using
the built-in Smart Bypass button. Simply press this button once and the Sensor Status
light will blink until the next time the Wireless RainSensor resets (dries out) -
all automatically.
Pressing the Smart Bypass button again resumes the active state.
Pressing the Smart Bypass button while the sensor is not active (dry or above freezing)
will cause the sensor to ignore the next rain/freeze signal.
Power Down
In order 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 unit back on.
Receiver Learn Mode
It may be necessary to set the receiver’s address code to the appropriate
Sensor/Transmitter if the units were purchased separately or if initial communication
testing fails. To do this, press and hold the Smart Bypass button until the Status and
Signal indicators blink in unison (12–15 seconds). Activate the corresponding
Sensor/Transmitter at close range (by pressing down on the 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 one of the following conditions exists:
•
The Sensor/Transmitter’s battery is getting low and should be replaced.
•
If the batteries are good, a problem with communication is indicated. Relocating the
Sensor/Transmitter may be necessary to provide a better signal.
•
The Sensor/Transmitter may have a dirty or jammed sensing mechanism. Check
and clean the cap and disk assembly, especially in areas prone to dirt or debris
accumulation.
