SETUP INSTRUCTIONS STEP-BY-STEP  
IMPORTANT: Make sure to observe the correct polarity when inserting batteries. The "+" markings on the  
batteries must line up with the diagrams inside the battery compartments. Inserting the batteries  
incorrectly may result in permanent damage to the units. During the initial setup process, place the  
wireless weather station and the outdoor sensors on a surface with 5-10 feet between each sensor and  
the weather station. Only use Alkaline batteries, rechargeable batteries may not work.

STEP 1: Complete initial setup on a table with all components within 10 feet of each other.  
STEP 2:  
It is important to allow sufficient light to reach the solar panel while activating the wind sensor. Make  
sure the lights are on in the setup room and the solar panel is facing a 60W light bulb or brighter.  
Ensure the solar panel is not covered, and then remove the black protective foil on the solar panel.  
Remove the tape covering the reset hole.  
Use the provided plastic reset rod to gently press the reset button once in the hole on the bottom of  
the sensor.  
Press Reset Button on  
Bottom of Wind Sensor  
(Solar Panel Must Face  
Light)  
STEP 3: Insert two "AA" size batteries into rain sensor with correct polarity.  
STEP 4:  
Insert two "C" size batteries into the thermo-hygro sensor with the correct polarity.  
Note: Allow all sensors to run for two minutes before inserting batteries in the weather station.  
STEP 5:  
Insert three "C" size batteries into the wireless weather station with the correct polarity.  
Note: Every time the wireless weather station receives data from the  
sensors, the wireless icons will blink once and then return to solid if the last  
transmission was successful. A wind speed or rainfall amount that reads "0"  
does not mean reception failure. It means that there was no wind or rain at the  
time of the last measurement. The thermo-hygro sensor syncs with the wind  
and rain sensors and sends all outdoor sensor data to the weather station. The  
thermo-hygro sensor tries for 4 minutes to sync to the wind sensor and then 4  
minutes for the rain sensor. If not successful within 4 minutes, the thermo-  
hygro sensor will stop looking for the other sensors.  
Wait 10 minutes for reception from all sensors before setting time and date or mounting sensors  
outside.  
STEP 6: Set Time and Date. See “Program Menu” below.  
Setup Troubleshooting: If the sensor data fails to display for any of the outdoor sensors within 10  
minutes (“- - -“are displayed), remove the batteries from all units for 1 minute and start the Setup  
procedure again at Step 1.

WEATHER FORECAST AND TENDENCY  
WEATHER FORECASTING ICONS  
For every sudden or significant change in the air pressure, the weather icons will update accordingly to  
represent the change in weather.  
Every time a new average pressure value has been obtained (once per minute); this value is compared  
with an internal reference value. If the difference between these values is bigger than the selected  
weather tendency sensitivity, the weather-icon changes, either for worse or for better. In this case, the  
current pressure value becomes the new weather tendency reference.  
If the icons do not change, either the air pressure has not changed or the change has been too small for  
the Weather Station to register. You may adjust the "sensitivity" of the pressure change check in the  
setting modesee WEATHER TENDENCY SENSITIVITY in the manual settings above.  
The displayed icon forecasts the weather in terms of getting better or worse and not necessarily  
sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon is  
displayed, it does not mean that the product is faulty because it is not raining. It simply means that the air  
pressure has dropped and the weather is expected to get worse but not necessarily rainy.  
Note: After set up, readings for weather forecasts should be disregarded for the next 48-60 hours.  
This will allow sufficient time for the Weather station to collect air pressure data at a constant altitude and  
therefore result in a more accurate forecast.  
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting  
feature is estimated to have an accuracy level of about 75% due to the varying areas the Weather Station  
has been designed for use. 75% accuracy is comparable to the best meteorological forecasting rate. In  
areas that experience sudden changes in weather (for example, from sunny to rain), the Weather Station  
will be more accurate compared to use in areas where the weather is stable most of the time (for  
example, mostly sunny).  
If the Weather Station is moved to another location significantly higher or lower than its initial standing  
point (for example, from the ground floor to the upper floors of a house), discard the weather forecast for  
the next 48-60 hours. The Weather Station may mistake the new location as being a possible change in  
air-pressure when really it is due to the slight change of altitude.  
WEATHER TENDENCY INDICATOR  
Working together with the weather icons is the weather tendency indicators (arrows located on the left  
and right sides of the weather icons). When the indicator points upwards, it means that the air-pressure  
is increasing and the weather is expected to improve, but when the indicator points downwards, the air-  
pressure is dropping and the weather is expected to become worse.  
For example, if the indicator is pointing downwards together with cloud and sun icons, then the last  
noticeable change in the weather was when it was sunny (the sun icon only). Therefore, the next change  
in the weather will be cloud with rain icons since the indicator is pointing downwards.

P a g e | 19  
 
     
Note: Once the weather tendency indicator has registered a change in air pressure, either the  
upward or downward tendency arrow will be displayed until the tendency changes again.  
AIR PRESSURE HISTORY GRAPH  
The LCD shows the relative air pressure value and the air pressure history on a bar graph.  
Press the SET button to toggle between Mode1 and Mode2 of the display.  
Mode 1: The bar graph displays the air pressure history of the  
past 24 hours in seven steps. The horizontal axis represents the  
last 24 hours of air pressure recording (-24, -18, -12, -8, -6, -3 and  
0 hour).  
Mode 2: The bar graph displays the air pressure history of the  
past 72 hours in seven steps. The horizontal axis represents the  
last 72 hours of air pressure recording (-72, -48, -36, -24, -12, -6  
and 0 hour).  
The vertical bars are plotted at each of the seven steps and give the trend over the recorded period. The  
0 hour vertical bar will always display at the midline height to indicate the current air pressure. The  
varying height of bars in other columns on the graph indicates a relative change in air pressure up or  
down from the 0 hour.  
New pressure measurements are compared to previously recorded pressure measurements. The  
pressure change is expressed by the difference between the current ("0h") and the past readings in  
divisions of ±0.06 inHg or ±2 hPa. If the bars are rising from left to right, this indicates that the weather is  
getting better due to an increase in air pressure. If the bars are falling from left to right, this indicates that  
the weather is expected to get worse due to a drop in air pressure.  
At every full hour, the current air pressure is used as a basis for the display of a new graph bar. The  
existing graph is then moved one column to the left.  
Note: For accurate barometric pressure trend, the weather station should operate at the same  
altitude. Should the unit be moved (for instance, from the ground to the second floor of the house), the  
readings for the next 48-60 hours should be discarded.  
Note: The bar graph will scroll right to left regularly to prevent LCD burnout.  
WIND DIRECTION AND WIND SPEED MEASUREMENT  
The longest pointer on the outer circle of the compass indicates the  
current wind direction.  
The last 6 wind directions may be displayed with shorter pointers on  
the inner circle.  
The wind direction (abbreviation or degrees) is displayed in center of  
compass.  
Press the SET button to toggle between Mode1 and Mode 2 of the  
display.  
Mode 1 displays the following wind data:

RAINFALL MEASUREMENT  
The 1hour, 24-hour, week, month or total rainfall measurement is displayed in the unit of inch or mm.  
For all measurements, it is important time and date are set correctly on your display.  
1-HOUR RAIN: The 1-hour rain reflects rain that has fallen from current time and back 1-hour. It  
updates every four minutes (15 measurements). The hour is not a fixed clock time measurement. It is  
literally an ongoing “last 60 minutes” timer.  
24-HOUR RAIN: The 24-hour rain reflects the rain that has fallen from current time and back 24-  
hours. This is not a midnight to midnight measurement. The day is not a fixed clock time  
measurement. It is literally an ongoing “last 24 hours” timer.  
WEEKLY RAIN: The amount of rainfall of the previous week. Week: Rain total for the week is reset  
every 7 days. Week begins 1 day before the day the batteries are first inserted into the weather  
station. For example, if the batteries are inserted on a Thursday, the start of the weekly totals will be  
Wednesday of each week.  
MONTHLY RAIN: Monthly rain reflects the previous month’s rain and will update 12AM the first day  
of the month.  
TOTAL RAIN: Total rain will remain until you manually reset this value. Total rain reflects the rain  
from time of display set-up until you manually reset the total rain.  
Note: RESET RAIN: Press and release the MIN/MAX button until the display shows the Total  
Rainfall value. Press the ▲/DATE button. The total rainfall amount will be reset to 0, and the  
time updated to current time.  
MIN/MAX WEATHER DATA  
The weather station will automatically record the maximum and minimum value of the various weather  
data with time and date of recording. Press and release the MIN/MAX button to view the following stored

last rainfall total reset.  
COMMON TERMS  
RELATIVE HUMIDITY  
Relative humidity is how close the air is to saturation (how much moisture the air can hold). On a warm  
day, more water can evaporate as there is more thermal energy to do the work of evaporation. Generally  
the higher the temperature, the lower the RH as more evaporation takes place.  
WIND CHILL-EQUIVALENT TEMPERATURE  
A fictional temperature that is felt by human beings under certain conditions instead of the measured  
temperature which can be taken into account during low temperatures. For La Crosse Technology®  
products, these conditions are a Temperature below 40°F and a wind velocity above 5 mph.  
WIND GUST  
A wind gust is a sudden, brief increase in the speed of the wind (less than 20 seconds) followed by a lull.  
This is different from a sustained wind.  
MOUNTING AND PLACEMENT OF SENSORS AND WEATHER STATION  
IMPORTANT: Ensure that all of the sensor data can be received at the intended mounting locations  
before you drill mounting holes. The outdoor sensors have a wireless range of 200 feet. Keep in mind  
that the 200 foot range equates to an open-air scenario with no obstructions. Each obstruction (roof,  
walls, floors, ceilings, etc.) will reduce the range.  
The thermo-hygro sensor measures outdoor temperature & humidity and collects the data from the  
wind and the rain sensors and sends all outdoor weather data to the wireless weather station, so the  
thermo-hygro sensor must be within the 200 foot wireless range of the wireless weather station. This  
allows the wind and rain sensors to be placed relative to the thermo-hygro sensor rather than the  
wireless weather station. See the Wireless Connection Diagram below.  
The wind and rain sensors must be mounted within the 200 foot wireless range of the thermo-hygro  
sensor and on the same side of the house. In addition, 915 MHz sensors transmit better at a  
minimum mount height of 6 feet.  
The wireless weather station must be within the 200 foot wireless range of the gateway to upload  
weather data to the Internet.  
M o d e l W S - 2 8 1 6 U - I T  
w w w . l a c r o s s e t e c h n o l o g y . c o m / s u p p o r t  
P a g e | 22  
 
         
If the sensor wireless reception icons drop from the weather station as you move them into their  
intended locations, the sensors may be too far from the wireless weather station. Try moving the weather  
station or the sensors closer and wait a few minutes to see if the wireless reception icons display again.  
If the wireless reception icons are still not displayed after re-positioning the sensors or the wireless  
weather station, hold the ▲/DATE button for 2 seconds to re-synchronize the weather station with the  
sensors.  
WIND SENSOR  
The wind sensor must be installed with the front of the sensor (the solar panel) facing true south, or  
the reported wind direction will not be accurate.  
Mount within the 200 foot wireless range of the thermo-hygro sensor and on the same side of the  
house. The roof may or may not be an ideal mounting location.  
Secure the main unit to the shaft of the mast holder. Use the right-angle adaptor to mount the wind  
sensor on a horizontal mast or surface.  
Fasten the wind sensor to a suitable mast using the U-bolt, washers and nuts included.  
Note: Mount the wind sensor onto a mast, at a minimum height of 6 feet, so the wind can reach the  
sensor unobstructed from all directions for an accurate reading. The ideal mast is between 0.62" and  
1.3” in diameter. The wind sensor DOES NOT have replaceable batteries; it consumes solar power  
and charges the internal battery pack automatically.  
Note: Do not open the wind sensor. This will void the warranty.  
Mounting Masts: A suitable mast must be made entirely of a non-conductive material (e.g. treated wood,  
electrical grade metal or electrical grade PVC).  
The issue is the static electricity transmission capability of the entire pipe, which can lead to erratic wind  
readings, or loss of signal. Coating or painting a pipe does not resolve the static or RF interference risks,  
as the inside of the material can conduct. The color gray is also not a guarantee of electrical grade  
protection. Any non-electrical grade mast may conduct, which may result in data spikes, RF interference,  
etc.

P a g e | 23  
 
 
RAIN SENSOR  
Mount the rain sensor on a level surface in an open area within the 200 foot wireless range of the  
thermo-hygro sensor and on the same side of the house.  
Mount the rain sensor at least 6 feet off the ground and level for optimum wireless transmission.  
The rain sensor should be accessible to allow for periodic cleaning of debris or insects.  
To avoid frequent build-up of debris, do not mount the rain gauge too close to the trees or plants.  
Remove the funnel portion (cover) of the rain gauge by twisting it firmly counter clockwise.  
Hold the base of the rain gauge flat against the mounting surface then use a level  
to make sure the rain gauge (as it rests on the mounting surface) is horizontally  
level.  
Use a pencil to trace the inside of the mounting holes on the base of the rain  
gauge to mark the screw locations.  
Drill a hole in the center of each marked location.  
Hold the rain gauge against the mounting surface so the holes on the base are  
aligned with screw holes, and then thread washer head screws (not included) into  
each hole and use a screwdriver to gently snug the screws.  
Note: Do not over-tighten the mounting screws.  
The Rain Gauge is self-emptying and can be left out all year or stored in the  
winter. If stored for the winter, remove the batteries to avoid leakage.  
Be aware of other wireless rain gauges in the area that may cause interference.  
THERMO-HYGRO SENSOR  
The thermo-hygro sensor is "weather resistant", but not "waterproof".  
To ensure an extended life for the sensor, mount it in a semi-covered place out of the  
elements at a minimum height of 6 feet.  
An ideal location for the thermo-hygro sensor is under the eaves on the North side  
of the house to avoid the effects of sunlight.  
Mount the sensor 18" down from the eaves to ensure optimum performance. This will  
assure the temperature of the air coming out of the attic will not affect data collected by the  
sensor.  
The cap on the sensor is for proper airflow for humidity reading and not rain protection. The  
Thermohygro sensor can withstand rain, snow and temperature extremes. Standing rain  
and snow may soak into the sensor and cause failure.  
To wall mount the thermo-hygro sensor, fix the wall holder onto the desired wall using the included  
screws, plug the sensor firmly into the wall holder and replace the rain cover if it is not already in  
place.  
Note: After mounting the units, if the weather data is not received, press and hold the /DATE button  
for 2 seconds to synchronize the weather station to the sensors.  
WEATHER STATION  
The Professional Weather Station is free standing with the base stand or can be wall mounted.  
Wall mount:  
Fix a screw (not supplied) into the desired wall, leaving the head extended out the by  
about 0.2 inches (5mm).  
Hang the weather station onto the screw. Ensure that it locks into place before  
releasing the professional weather station.  
Free standing: Simply pull out the stand to the back of the weather station and place on  
a flat surface.

Position:  
Choose a location 6 feet or more from electronics such as cordless phones, gaming systems,  
televisions, microwaves, routers, baby monitors, etc., which can prevent signal reception.  
Place within range of the outdoor transmitters. The maximum transmitting range in open air is 200  
feet (60 meters).  
Be aware of electrical wires and plumbing within a wall. This will interfere with signal reception.  
Obstacles such as walls, windows, stucco, concrete, and large metal objects can reduce the range.  
Position the weather station to receive outdoor data from the thermo-hygro sensor and send data to  
the gateway.  
GATEWAY  
Position the gateway within range (200 feet open air) of the  
weather station.  
The gateway should be installed indoors in an easy-to-reach  
location.  
Registration requires that you press the gray button on the  
gateway.  
It can be mounted securely to the wall with the included mounting  
plate and drywall anchors.  
Note: If you require a longer LAN cable to mount the gateway in a  
desired location, any standard Category 5 network cable will work, but  
a crossover cable may not work. Crossover cables designed to connect two computers without  
networking hardware may not work with your gateway.  
Note: Network cables usually have length limitations. The same length limitations will apply that apply  
to computers on your home network.
