Connect the RED and
BLACK wires to the SLHUB1
communication hub as shown:
• RED wire to Left terminal
• BLACK wire to Right terminal
Refer to the SmartLine Owner’s
Manual for complete controller
setup and programming
instructions, prior to activating
the SLW1.
Activate the SLW1 On-Site
Weather Station by pressing the
rain sensor stem on the top of
the SLW1 for 15 seconds.
Return to the SmartLine
controller and verify the
antenna icon appears on
the bottom line of the LCD
display. The flashing
antenna icon indicates
communication has been
established in the past 5
minutes. A non-flashing antenna icon indicates
communication has occurred in the past 5 days. If no
antenna icon is present, repeat the activation process
above.
Note: In the event communication is lost between the
SLW1 weather station and SmartLine controller,
a FAULT message will be displayed. Consult the
SmartLine Owner’s Manual for instructions on
how to read fault messages. After 5 days of no
communication with the SLW1, the SmartLine
controller will automatically revert to Standard
mode operation.
The SLHUB1 will initiate communications with the SLW1
periodically during each day to retrieve weather data.
Every night at midnight, the SmartLine controller will log
daily high and low temperatures. Consult the SmartLine
Owner’s Manual for instructions on how to view the SLW1
5 day temperature history.
On the SmartLine control panel, press the MODE button
to select Auto Adjust mode. If the Auto Adjust LED flashes
RED and reverts to Standard mode, hold down the MODE
button and read the scrolling message indicating actions
needed to enter Auto Adjust mode.

SLW1 Weather Station Installation & Operation Instructions
Rain/Freeze Sensing Functions
The SLW1 weather station
provides rain and freeze sensing
to prevent watering during
periods of rain and freezing
weather.
The rain override will stop
watering after the selected
amount of rain is received
(factory setting is 1/8inch).
Available settings are 1/8inch to
¾ inch (3 to 19 mm) Using the
lock tab, select the desired setting.
Note: During rain shutdown, high/low temperatures of
60/60 are reported to the SmartLine controller
and Auto Adjust deficits and run times will reset to
zero.
The SLW1 weather station freeze sensing function will prevent
watering when the outside temperature drops below 37
degrees Fahrenheit (1.5 degrees Celsius). Watering can
resume when the temperature increases above 37 degrees F
(1.5 degrees Celsius).
The Sensor LED in the Active position will display RED during
rain or freeze periods. Additionally, after a rain event, the
SmartLine controller will continue to pause watering for 48
hours after the rain sensor has disengaged, in order to prevent
over watering. During the 48-hour extended rain delay, the
Active Sensor LED is ORANGE. In the event you choose to
end the 48-hour extended rain delay, press the Sensor button
on the SmartLine control panel twice and the Sensor LED
will return to a GREEN color and permit watering. SmartLine
controllers with firmware 3.05 and higher have a selectable
SLW DELAY feature in Advanced Functions that allows the
factory default dry out period of 48 hours, to be set for 0 to
99, hours if desired for local conditions.
Maintenance
The SLW1 weather station is designed for years of
maintenance-free operation. The SLW1 does not utilize any
onboard power source. Operational power is provided from
the controller.
The rain sensor Assembly, part # SLW1DISKASSY, is
replaceable. To remove the module, turn the rain sensor
housing so the rainfall set tab is disengaged and lift out the
module.
The mounting arm assembly, part # SLW10BSA, is replaceable.
