NOTE: The rst diagnostic blink indicates the strength of the 2
AAA lithium batteries in the RFS5. A Red blink would indicate a
need to replace the batteries. Capable life for the lithium
batteries is 10 years. If the 2nd and 3rd blinks are Red,
replacement of the weather station is required.
NOTE: A separate RFS5 weather station is required for each
ProLine® controller that you are installing.
Step 3: Conduct communication range
Press the rain spindle wick for 15 seconds and go to the ProLine®
controller. If you have RF communication, the antenna icon on the
ProLine® display should be blinking.
NOTE: The blinking will continue for 5 minutes after any communication from the RFS5. After 5 minutes,
the antenna icon will remain static until the next communication. Press the Mode button and place the
ProLine® into the Rain/Freeze Sensor position. If the installation is successful, you will have a Green light
at Rain/Freeze Sensor. In addition, the operating panel on an PL1600 or PL4800 must be closed so that
AC is present. You will get a communication error if the panel is showing NO AC.
Step 4: Choosing a location and Mounting the RFS5
1. Decide on a good mounting location for your RFS5 wireless
rain/freeze sensor. The mounting location should be one that is
not a ected by a heat source such as an air conditioner, hot
roof, hot asphalt, etc. Mount in an area with unobstructed
air ow. Mounting is preferred in direct sunlight with good air
ow. Additionally, the location must have open access to
rainfall (cannot be covered by any overhead obstruction such
as trees, roofs, etc.). Mount the RFS5 as close as possible to the
controller. Obstacles such as earth, hills, walls or other
structures will reduce the maximum operating range of the
RFS5. Use the diagnostic LED in the RFS5 to verify
communication and to check operating range at a speci c
location. Extreme conditions may prevent wireless communication.
2. Attach mounting bracket to a smooth surface using the two mounting screws (supplied) or attach to
gutter using the wing nut provided. You may choose to remove the mounting bracket from the bracket
arm for easier installation. Make sure the RFS5 is xed in a vertical position. Tighten all wing nuts to make
sure unit is held vertical.
Rain/Freeze Sensing Function
The SLW5 wireless weather station provides rain and freeze sensing
functions to prevent watering during periods of rain and The RFS5
wireless rain/freeze sensor provides rain and freeze sensing functions to
prevent watering during periods of rain and freezing weather. The rain
override will pause watering after a minimum of 1/4 inch (6.35mm) of
rainfall is received, based on the 1/4 inch (6.35mm) factory rain sensor
setting. Settings can be changed incrementally up to 3/4 inch (19mm).
