QUICK SETUP

Hint: Use good quality Alkaline Batteries
and avoid rechargeable batteries.

1. Have the indoor weather station and

remote temp/humidity sensor 3 to 5 feet
apart.

2. Batteries should be out of all units for

10 minutes.

3. Place the batteries into the remote

temp/humidity sensor first, then into
the indoor weather station.
(All remote temp/humidity sensors
must be started before the indoor
weather station)

4. DO NOT PRESS ANY BUTTONS

FOR 15 MINUTES.

In this time the indoor weather station and
remote temp/humidity sensor will start to
talk to each other and the displays will show
both the indoor temperature and an outdoor
temperature and humidity. If the indoor

5

weather station does not display both the
indoor temperature and the outdoor
temperature and humidity after the 15
minutes please retry the set up as shown on
page five.

After both indoor temperature and outdoor
temperature and humidity are displayed for
10 minutes you can place your remote
temp/humidity sensor outdoors and set your
time.

Notes on Outdoor Sensor Placement

The remote temp/humidity sensor should be
placed in a dry, shaded area. Fog and mist
will not harm your remote temp/humidity
sensor but direct rain must be avoided.

The remote temp/humidity 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 can
have up to 30 feet of resistance and an

6

interior wall can have up to 20 feet of
resistance. Your distance plus resistance
should not exceed 330 ft. in a straight line.

To complete the set up of your indoor
weather stations after the 10 minutes have
passed, please follow the steps below.

1. Press and hold the “SET” button for

two seconds.

2. The minutes will now be flashing.

C. ADDING ADDITIONAL

REMOTE TEMP/HUMIDITY
SENSORS (OPTIONAL)

The WS-7107U is able to receive signals
from 3 different remote temperature,
temperature/humidity sensors. Following
are some brief instructions for the basic

13

set-up of remote sensor units with the
WS-7107U. These extra sensors can be
purchased through the same dealer as
this unit, or by contacting La Crosse
Technology directly. A TX6 will
monitor temperature only, a TX3U will
monitor temperature and display the
temperature on its LCD, the TX3UP will
monitor the temperature via a probe for
use in pools, spas, etc and the TX4U or
TX7U will monitor temperature and
humidity.

Note: When setting up multiple units it
is important to remove the batteries from
all existing units in operation, then to
insert batteries first into all the remote
temp/humidity sensor units, and in
numeric sequence. Second, install
batteries into the indoor weather station.
Transmission problems will arise if this
is not done correctly and if the total time
for set-up exceeds 6 minutes.

14

It is necessary to remove the batteries

1.

from all units currently in operation.

2.

Remove the battery covers to all
remote sensor units.

3.

Place all remote sensor units in a
numeric sequential order.

4.

In sequential order, install batteries
(follow the same battery installation
procedures seen in section “I” of the
Detailed Set-Up Guide) into the
remote sensors.

5.

Install batteries into the indoor
weather station.

6.

Follow the Detailed Set-Up Guide for
programming and operating
instructions.

MOUNTING

Note: To achieve a true temperature

reading, avoid mounting in direct sunlight.
We recommend that you mount the remote
temp/humidity sensor on an outside North­facing wall. The sending range is 330ft;
obstacles such as walls, concrete, and large
metal objects will reduce the range. Place
both units in their desired location
temporarily to test reception capability
before permanently mounting.

A.

2.

To wall mount:

a)

Remove the table stand by pulling
down on the stand from the rear and
rotating forward.

b)

Fix a screw (not included) into the

desired wall.

c)

Place the indoor weather station
onto the screw using the hanging
hole on the backside.

d)

Gently pull the indoor weather

station down to lock the indoor
weather station into place.

TROUBLESHOOTING

NOTE: For problems not solved, please
contact La Crosse Technology via e-mail or
phone, or visit our website,
www.lacrossetechnology.com

Problem: The LCD is faint
Solution: Replace batteries

Problem: No outdoor temperature or

humidity is displayed.

Solution:

1) First try to re-establish communication

between the remote sensor and indoor
weather station by moving both units to
within three to five feet of each other.
Wait about ten minutes and then check
for a temperature and humidity.

2) If this does not work please remove the

batteries from both units and restart the
system (please see Detailed Set-up on
page nine through eleven).

Note: Please make sure when restarting the
system that all batteries are fresh.

19

3) Once the system has been reset and you

have a temperature and humidity reading
from the sensor, temporarily place the
remote temp/humidity sensor in the
previous location.

Note: If there is an outdoor temperature and
humidity displayed when the two units are
close together there was either too much
distance between the two units previously or
some type of interference that was causing
poor reception.

4) If after 15 minutes the temperature and

humidity are not displayed you will need
to choose another location for placement
of the temp/humidity sensor.

5) The best way of doing this is to move the

sensor 10 feet closer to the indoor
weather station.

6) After moving the remote temp/humidity

sensor please wait 15 minutes to give the
indoor weather station time to re-acquire
the signal.

20

Problem: Temperatures do not match if
units are placed next to each other.
Solution: Each temp/humidity sensor is
manufactured to be accurate to within 2
degree plus or minus and under normal
conditions. It is possible for two
temp/humidity sensors to be as much as 4
degrees different. The difference can be
exaggerated further because the
temp/humidity sensors are designed for
different working environments. The indoor
sensor is less responsive to ambient air
currents because of the shielding effect of
the indoor weather station’s case. In
addition, the casing can act as a heat sink to
absorb and store heat from external sources
(i.e. handling of the case or radiant heat). In
addition, the much greater range of the
outdoor temp/humidity 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

21

compensate for the above factors and obtain
an accurate comparison.

MAINTENANCE AND CARE
INSTRUCTIONS

• Extreme temperatures, vibration, and

shock should be avoided to prevent
damage to the units.

• Clean displays and units with a soft,

damp cloth. Do not use solvents or
scouring agents; they may mark the
displays and casings.

• Do not submerge in water.

• Do not subject the units to unnecessary

heat or cold by placing them in the
oven or freezer.

• Opening the casings invalidates the

warranty. Do not try to repair the unit.
Contact La Crosse Technology for
repairs.
