Tips for installing and using La Crosse Technology’s Professional Wireless Weather Stations 

Models WS-2010, WS-2210, WS-7015 

 

4. 

The indoor sensor

 should be mounted in a location 

where main indoor temperature measurement is desired. 
Keep away from sources of heat and cool. 

Setting Up 

1.  Insert magnets in the outdoor sensors (three) 

a.  Be sure to make note of the colored magnet for the 

rain gauge, and put bucket together properly. 

5. 

The transmission signal

 travels in a straight line from 

the sensor to the display/receiver. Any obstacles in this 
path may cause interference and limit the range. A typical 
wall will decrease the signal range about thirty feet (300 
feet is the rated range in free space). 

b.  Be sure to firmly press the magnet in (about 1/8” will 

be out of the opening) 

2.  Insert two AA batteries into the indoor sensor. This 

sensor measures temperature, humidity, and air pressure 
and transmits it to the display/receiver. 

 

Operating Tips 

3.  Wait ten minutes, then insert four AA batteries into 

display/receiver and wait for ten minutes without pressing 
buttons to allow full set up. 

1. 

Minimum and maximum

 values are stored for all data 

(no minimum rain or wind). Press the “Min/Max” key 
once to view minimum values. Press the “Min/Max” key 
again to view maximum values. While viewing all 
minimum or maximum data, press the 

Í

 or 

Î

 keys to 

scroll through each value with the corresponding time and 
date of occurrence. To exit this mode, view all minimum 
or maximum values and press the “Min/Max” key to exit. 

4. 

Calibrate

 and set the time and date (NOTE: the time and 

date needs to be set for proper operation) 
a. Press 

the 

Í

Î

, and Calbr. Buttons at the same 

time. “0000” inHg (altitude) is displayed. 

b.  Press the + to increase the altitude setting. Please 

note the altitude adjustment is in meters. If you know 
your altitude in feet, multiply this by 0.305 to get 
meters. If you do not know your altitude, watch the 
local weather to find the air pressure, and adjust the 
altitude until the air pressure matches. You may press 
the “Unit” key to switch between inHg and hPa. 
Press the 

Í

 key once. 

2. 

Alarms

 can be set for all values (except rain). Press the 

Í

 and 

Î

 keys to enter the programming mode. Press the 

Í

 or 

Î

 keys to scroll through each value and press the + 

or – to adjust the value. Press the “Min/Max” key to 
toggle between minimum alarm and maximum alarm. 
When a minimum alarm is set, any value received below 
that will sound the alarm; press the “Alarm” key to shut 
off the alarm. 

c.  “1.45 in” is displayed in the rain section. This is the 

rain multiplicator; each tip of the rain bucket 
represents 0.0145 inches of rain. This can be 
adjusted, but it is not recommended. You may press 
the “Unit” key to switch between inches and 
millimeters for rain measurement. Press the 

Í

 key. 

3. 

Rainfall

 can be viewed as total (cumulative until reset), 

1h (1 hour total updated at the bottom of the hour), or 24h 
(24 hour total from 7 am to 7 am). For example, at 3:45 
pm on Wednesday, you will see the total rainfall since the 
last reset, the 1 hour total from 2:30 pm to 3:30 pm., and 
the total from 7 am Tuesday to 7 am Wednesday. 

d.  The time and date are displayed in the lower left 

hand corner. Press the corresponding keys to advance 
the time or date. “Wind” for hour, “Rain” for minute, 
“Alarm” for month, “Sensor” for day. Press the 

Í

 

key once. 

4. 

Wind

 readings are continuously monitored, and 

transmitted once every three minutes. The value 
displayed is the maximum wind recorded during that 
three minute period, along with the average wind 
direction, represented by arrows around the compass. 
Wind units may be changed by pressing the “Wind” key.  

e.  Three “7’s” are displayed; in indoor temperature, 

wind, and rainfall. This is the addressing for those 
sensors, and must be set to 7’s. If not, press the 
appropriate key to advance to the correct number 
(indoor, wind, or rain). You may press the “Unit” 
key to switch between 

°

F or 

°

C. Press the “Store” 

key to end calibration mode. 

5. 

Solar panels

 are integrated in three of the four sensors. 

These sensors also include a Lithium button cell battery 
that will recharge during the day and power the unit at 
night. The battery is expected to last seven to ten years. 
Occasionally the display/receiver can lose transmission 
from a sensor and display “--.-“. This may be due to 
outside interference (cordless phones, wireless 
headphones, etc.) or not enough sunlight. Such losses of 
signals should be very infrequent, and will return 
automatically through an automatic search at 8 am and 6 
pm. If the loss of communication is consistent, it may 
require moving the sensor. 

 

Mounting Sensors 

1. 

The outdoor temperature and humidity sensor

 should 

be mounted in the shade with enough reflected light to 
power the solar panel; placement on the East side of a 
house with two or three hours of cool morning sun works 
very well. While not much light is required, enough light 
to power a solar-powered calculator is needed. 
Insufficient light can result in “--.-“ to be displayed in the 
temperature section. In this case, moving the sensor is 
required. 

6. 

The forecast and weather trend

 is based on the 

changing air pressure over time. When air pressure falls, 
worsening conditions are expected. When air pressure 
rises, the weather is expected to clear up. The symbols are 
relative to current weather; thus, a sunny icon may not 
indicate the forecast of sunny weather, but rather clearing 
conditions. The forecast is for 6 to 12 hours in the future, 
and is about 75% accurate overall. Areas that are not 
affected as much by the air pressure change may find the 
forecast accuracy to be less than 75%. 

2. 

The wind sensor

 should be mounted in the open, 

preferably on a roof. The solar panel needs to face due 
South for a reference point for direction. The mast it is 
mounted on needs to be stable and not subject to 
vibrations. 

3. 

The rainfall sensor

 should be mounted in the open on a 

horizontal surface. Leaves and other debris may collect in 
the bucket and should be cleaned once in a while.
