ADDITIONAL EQUIPMENT (not included)
1. Two fresh AAA 1.5V alkaline batteries for the remote temperature sensor.
3. One, Philips screwdriver for mounting.
QUICK SETUP
Hint: Use good quality Alkaline Batteries; avoid rechargeable batteries.
1. Have the Wireless Weather Station and Temperature sensor 3 to 5 feet apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the Temperature sensor first and next into the Wireless Weather
Station.
4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.
In this time the Wireless Weather Station and the temperature sensor will begin to communicate with
each other, and the display will show both the indoor temperature and an outdoor temperature. If the
Wireless Weather Station does not display both temperatures after the 15 minutes, please retry the
set up as stated above. After both indoor and outdoor temperatures are displayed for 15 minutes you
can place your temperature sensor outdoors, and set your time.
The temperature sensor should be placed in a dry, shaded area (ex: under the eve of a roof). The
temperature sensor has a range of 330 feet. Any walls that the signal will have to pass through will
reduce distance. An outdoor wall or window will have up to 20 feet of resistance and an interior wall
will have up to 10 feet of resistance. Your distance plus resistance should not exceed 330 feet in a
straight line.
NOTE: Fog and mist will not harm your temperature sensor, but direct rain must be avoided.

DETAILED SETUP GUIDE
I. BATTERY INSTALLATION (When one Temperature sensor is being used)
1. First, insert the batteries to the Temperature sensor (see “A. Temperature sensor” below).
2. Within 2 minutes of powering up the sensor, insert the batteries to the Weather Station (see
“B. Wireless Weather station” below). Once the batteries are in place, all segments of the
LCD will light up briefly. Following the indoor temperature and the time as 12:00 will be
displayed, and the signal reception icon will flash. If they are not shown in LCD after 60
seconds, remove the batteries and wait for at least 60 seconds before reinserting them. Once
the indoor data is displayed user may proceed to the next step.
3. After the batteries are inserted, the Weather Station will start receiving data signal from the
sensor. The outdoor temperature should then be displayed on the Weather Station. If this does
not happen after 2 minutes, the batteries will need to be removed from both units and reset
from step 1.
A. TEMPERATURE SENSOR
1. Remove the Battery Cover.
2. Observing the correct polarity, install 2 “AAA” Alkaline
Batteries—make sure they do not spring free, or start-up
problems may occur.
3.Replace the Battery Cover.
OUTDOOR TEMPERATURE
The temperature received from the remote temperature sensor is viewed in the OUTDOOR LCD.
When there is more than one remote temperature sensor unit in operation, a “boxed” number will
appear to the right of the temperature. This indicates which remote temperature sensor unit (1, 2, or
3) is currently displaying its data in the OUTDOOR LCD. (This feature is explained in further detail in
the section—Adding Remote Temperature Sensors).
OPTIONAL CHANNEL 2 TEMPERATURE PROBE
When the temperature probe is connected to the remote temperature sensor, the WS-9029U’s
channel 1 will display the remote temperature sensor data, and channel 2 will display the temperature
probe data. The remote temperature sensor data will always be displayed on the channel 1 and the
temperature probe on the channel 2.
If the probe on remote temperature sensor is unplugged, the "probe channel" on WS-9029U LCD will
show "---", the remote temperature sensor displayed value will still be shown.
The probe can be connected to the remote temperature sensor anytime. There is no need to reset the
units. The Weather Station will automatically detect the temperature probe and will display the
temperature probe data in channel 2.
ADDING TEMPERATURE SENSORS (OPTIONAL)
The WS-9029U is able to receive signals from 2 remote temperature sensors (TX-25U). These extra
sensors can be purchased through the same dealer as this unit

A. SET-UP OF MULTIPLE SENSORS
1. Remove all the batteries from the receiver and sensor(s) and wait 60 seconds. During these
60 seconds, press any button 20 times to discharge any excess power.
2. Insert the batteries to the first sensor.
3. Within 2 minutes of powering up the first sensor (Temperature sensor with probe), insert the
batteries to the Weather Station. Once the batteries are in place, all segments of the LCD will
light up briefly. Following the indoor temperature/humidity and the time as 12:00 will be
displayed, and the signal reception icon will flash. If they are not shown in LCD after 60
seconds, remove the batteries and wait for at least 60 seconds before reinserting them.
4. The outdoor temperature from the first sensor (channel 1) should then be displayed on the
Weather station. If this does not happen after 2 minutes, the batteries will need to be removed
from both units and reset from step 1.
5. If the temperature probe has been used, the outdoor temperature from channel 2 will then be
displayed. Otherwise, the outdoor temperature will display “---“.
Note: The temperature probe from the first sensor will always occupy “channel 2”. Channel 2 can
only be used for the temperature probe. If you choose not to use the temperature probe, Channel
2 will display “---“.
6. Insert the batteries to the second sensor as soon as the outdoor temperature readings from
the first sensor are displayed on the Weather station.
NOTE: You must insert the batteries into the second sensor within 30 seconds of
reception of the first sensor.
7. The outdoor temperature from the second sensor and the "channel 3" icon should then be
displayed on the Weather station. If this does not happen after 2 minute, the batteries will need
to be removed from all the units and reset from step 1.
Note: only the readings from the internal sensor of the second sensor will be displayed in “channel 3”
IMPORTANT: Transmission problems will arise if the setting for additional sensors is not
followed as described above. Should transmission problems occur, it is necessary to
remove the batteries from all units and start again the set-up from step 1.
B. VIEWING AND OPERATING WITH MULTIPLE TEMPERATURE SENSOR UNITS
1. To view the temperature of a different remote temperature sensor unit, press and release the
SET/CH button. A shift from one “boxed” number to the next should be observed in the
OUTDOOR LCD.
2. To determine which remote temperature sensor reading is displayed on the 3 channels, match the
temperature displayed on each channel, with the corresponding temperature displayed on the
LCD of each remote temperature sensor.
3. To view the Minimum/Maximum temperature: first select which remote temperature sensor to read
data from (indicated by the “boxed” number), then press the SET/CH button. Pressing this button
once will display the minimum temperature, and the date and time the data was recorded.
Pressing this button a second time (while “MIN” is still displayed, otherwise press the button twice)
will display the same data for the maximum recordings.
4. To reset the Minimum/Maximum readings, press and hold the MIN/MAX/+ button for 5 seconds,
this will reset all the minimum and maximum data from all sensors.
MOUNTING
THE REMOTE TEMPERATURE SENSOR
1. Remove the mounting bracket/stand from the temperature sensor.
2. Place the mounting bracket over the desired location.
3. The mounting bracket can attach to the sensor in the middle of the back or on the bottom.

4. Through the 3 screw holes of the bracket, mark the mounting surface with a pencil.
5. Screw mounting bracket onto the mounting surface. Ensure that the screws are flush with the
bracket.
6. Insert the remote temperature sensor into the bracket.
Problem: No outdoor temperature is displayed.
Solution: 1) Remove all batteries, reinsert into sensor first, then into the wireless weather station.
2) Place remote temperature sensor closer to wireless weather station.
3) Be sure all batteries are fresh.
4) Place remoter temperature sensor and wireless weather station in position so the straight-line
signal is not passing through more than 2 or 3 walls.
Problem: Temperatures do not match if units are placed next to each other.
Solution: Each remote temperature sensor is manufactured to be accurate to within 1 degree plus or
minus and under normal conditions, so two sensors could be as much as 2 degrees different.
However, the difference can be exaggerated further because the sensors are designed for
different working environments. The indoor sensor is less responsive to ambient air currents
because of the shielding effect of the display's case. In addition, the case can act as a heat
sink to absorb and store heat from external sources (i.e. handling of the case or radiant heat).
Also, the much greater range of the remote temperature sensor requires a different calibration
curve than the indoor range. Error is usually greater at the extreme ends of a range, making it
harder to compare different ranges with different curves. Under non-laboratory conditions, it is
difficult to compensate for the above factors and obtain an accurate comparison.
MAINTENANCE AND CARE INSTRUCTIONS
9Extreme temperatures, vibration, and shock should be avoided to prevent damage to the units.
