The SLW5 is a wireless weather station 

operating on a 900 MHz bi-directional 

frequency.  Maximum  range is 1500 feet 

(457m) Line of Sight (LOS). The SLW5 is 

operable with all SmartLine® models and 

firmware versions.  The SLW5 and SLHUB-

RF-5 are “pre-paired” or synched at the 

factory for your convenience. 

Before You Get Started

Loosen the screws to the bottom cover of 

the SLW5.  Rotate the cover in the keyholes 

and remove. Install the two (2) AAA lithium 

batteries provided. 

NOTE: 

Pay attention to correct polarity when 

installing the batteries.  Incorrect installation may cause 

damage to the product and/or performance.

Step 1:  Install the SLHUB-RF-5

The SLHUB-RF-5 is the wireless 

transceiver that communicates 

with the SLW5. The SLHUB-

RF-5 is supplied with your 

SLW5. To install in your 

SmartLine® controller, open the 

control panel on the SL1600 

or the large front panel of the 

SL4800. On the SL800, remove 

and discard the hub cover panel from the back of the SL800 

housing.
Insert the SLHUB-RF-5 into the mating pin connector holes. Be 

careful not to bend the connecting pins. 

Secure the SLHUB-

RF-5 to the housing with the supplied flathead machine 

screw.

 The RF antenna will hang down inside the SL1600 or 

SL4800 housing. On the SL800, allow the RF antenna to hang 

underneath the controller.
Make sure AC power is supplied to the SmartLine® controller 

and then proceed to Step No. 2.

Step 2:  Initializing SLW5 weather station

1.  Program auto adjust settings in 

controller.

2.  While standing in front of 

controllers, press the rain spindle 

on the top of the SLW5 for 15 

seconds; then watch the LED 

which is visible through the 

openings in the cover at the 

bottom of the SLW5. You will see 4 

blinks. All blinks should be Green. 

At this time, put the controller into Auto Adjust mode on 

controller. 

NOTE: 

If the controller fails to hold in auto adjust mode, press 

the auto adjust button and hold for instructions in display 

related to issue that failed to allow controller to be placed in 

auto adjust mode.

NOTE:

 The 4th (final blink) indicates the strength of the RF 

communication. If the 4th blink is Red, you do not have a 

satisfactory RF communication. Move the SLW5 to a different 

mounting location and repeat the diagnostic procedure.

NOTE:

 The first diagnostic blink indicates the strength of 

the 2 AAA lithium batteries in the SLW5. A Red signal 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 SLW5 weather station is required for each 

SmartLine® controller that you are installing.

Step 3:  Conduct communication range

Press the rain spindle for 15 seconds and go to the SmartLine® 

controller. If you have RF communication, the antenna icon on 

the SmartLine® display should be blinking.  

NOTE:

 The blinking will continue for 5 minutes after any 

communication from the SLW5. After 5 minutes, the antenna 

icon will remain static until the next communication. Press the 

Mode button and place the SmartLine® into the Auto Adjust 

position. If the installation is successful, you will have a Green 

light at Auto Adjust. If you see a message that “weather data 

is needed” re-check the installation and/or the required data 

input into the controller. Required data is zip code/latitude 

and correct time and date.  In addition, the operating panel on 

and SL1600 or SL4800 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 SLW5

1.  Decide on a good mounting location for your SLW5 

wireless weather station. The mounting location should 

be one that is not affected by a heat source such as an 

air conditioner, hot roof, hot asphalt, etc. Mount in an area 

with unobstructed airflow. Mounting is preferred in direct 

sunlight with good air flow. Additionally, the location must 

have open access to rainfall (cannot be covered by any 

overhead obstruction such as trees, roofs, etc.). Mount 

the SLW5 as close as possible to the controller. Obstacles 

such as earth, hills, walls or other structures will reduce 

the maximum operating range of the SLW5. Use the 

diagnostic LED in the SLW5 to verify communication and 

to check operating range at a specific location.  Extreme 

conditions may prevent wireless communication; in this 

circumstance, use the SLW1 wired weather station.
