Press Reset Button on
Bottom of Wind Sensor
(Solar Panel Must Face
Light)
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 setup
process, place the wireless display and the outdoor sensors on a surface with 5-10 feet
between each sensor and the display.
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 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.
STEP 3:
Insert two "AA" size batteries into the rain sensor with the correct polarity.
STEP 4:
Insert two "C" size batteries into the thermo-hygro sensor with the correct
polarity. Allow all sensors to run for two minutes before inserting batteries
in the weather station.
STEP 5:
Insert two "C" size batteries into the wireless display with the correct
polarity.
NOTE: Every time the wireless display 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
display. 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 “Manual Settings” below.

P a g e | 9
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.

If you do not wish to reset the display to factory defaults, either:
Press the MIN/MAX button or the ALARM button to exit SET mode, or
Simply wait 30 seconds until the SET mode times out and returns to the Mode 1 display.
To reset the display to the factory defaults, follow the procedure below.
WARNING:
A factory reset will erase the connection between the display and the thermo-hygro sensor and
require the all sensor connections to be re-established.
1. "rES oFF" will flash.
2. Use the ▲/DATE button or ▼/RAIN button to select "rES on".
3. Press the SET button to confirm and a countdown timer will begin counting down from
"127" When the timer displays "dOnE", you must remove the batteries from the display

P a g e | 15
4. After waiting for 10 minutes, insert the batteries into the thermo-hygro sensor, and rain
sensor making sure to align the "+" symbol on the batteries with the markings on the
battery cover and inside the battery compartment.
5. Within 2 minutes of inserting the batteries into the sensors, insert the batteries into the
display, making sure to align the "+" symbol on the batteries with the markings inside the
battery compartment.
6. Wait 5 minutes for the outdoor weather data to display. If any of the outdoor data
displays "--" after waiting for 5 minutes, follow the "Set Up Instructions” near the
beginning of this manual or in the Quick Set Up Manual included with the product.
TO EXIT THE MANUAL SETTING MODE:
To exit the manual setting at any time, either:
Press the MIN/MAX button or the ALARM button to exit SET mode, or
Simply wait 30 seconds until the SET mode times out and returns to the Mode 1 display.
WEATHER ALARM OPERATIONS FOR THE WEATHER STATION DISPLAY
The Weather alarms can be set when certain weather conditions are met. For example, you can
set the thresholds for the outdoor temperature to +104°F (high) and 14°F (low), while enabling
the high alarm and disabling the low alarm (i.e. temperatures <14°F won’t trigger alarm, but
temperatures >+104°F will).
When the value meets the condition for high alarm or low alarm, the alarm will ring for 2
minutes and the value will blink, along with the corresponding icon ("HI AL"/ "LO AL").
Press any button to stop a ringing alarm.
The high and low alarms can be switched On/Off independently, according to the needs.
If at any time during the alarm setting process you would like to exit alarm setting mode,
press the MIN/MAX button or wait for about 30 seconds and the display will return to normal
display mode automatically.
Press the ALARM button to enter ALARM mode. Subsequent presses of the ALARM button
will advance to the next weather alarm section.
Note: Weather alarms can also be set from the Heavy Weather Pro software. Consult the
Heavy Weather Pro Software User’s Guide for instructions.
Note: Remote Monitoring and Alerts Activation Card has instructions for downloading the La
Crosse Alerts software and the needed activation key to enable this feature.
THE FOLLOWING WEATHER ALARMS CAN BE SET IN ALARM MODE:

HYSTERESIS
To compensate for fluctuation of the weather data, which may
cause the weather alarm to ring constantly if the measured
reading is close to the alarm level, a hysteresis function has
been implemented for each weather alarm.
For example, if the high temperature alarm is set to 77°F and
the temperature reaches 77°F, the alarm will be activated. If the
temperature then drops to 76.8°F (a change of less than 1.8°F) and then increases to 77°F
again, the data will blink, but no alarm will be activated.
The temperature would have to drop below 75.2°F (with a pre-set hysteresis of 1.8°F) so that
the alarm can be produced again. Hysteresis values for the various weather data types are
given in the table.
Note: The temperature or humidity data will keep flashing even after the weather alarm has
been switched off by a button press. The flashing value indicates that the current weather
condition is out of the pre-set weather alarm limit(s).

WEATHER FORECAST AND TENDENCY
WEATHER FORECASTING ICONS:
Sunny
Cloudy with sunny intervals
Rainy
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 Center to register. You may adjust the "sensitivity" of the pressure change
