La Crosse Technology Outdoor Temperature/Humidity Sensor TX7U User manual

TX7U Outdoor Temperature/Humidity Sensor
The TX7U outdoor temperature/humidity sensor can be added to your existing
units in operation. The outdoor temperature/humidity sensor measures the
outdoor temperature and humidity (or any other location you wish to know the
temperature and humidity) and transmits the data to the indoor display station.
INVENTORY OF CONTENTS
1. Outdoor temperature/humidity sensor.
2. Mounting bracket.
3. Rain protector.
4. Two each, ½” Philips mounting screws.
5. One strip double sided adhesive tape.
6. Instruction manual and warranty return card.
ADDITIONAL EQUIPMENT (not included)
1. One Philips screwdriver.
2. One Flat screwdriver.
3. Two fresh AA 1.5V batteries.
I. SETTING UP
Before you begin, assign a number to each outdoor temperature/humidity sensor
(i.e. #1 for outdoors, #2 for the basement, etc.) if you have multiple sensors. This
will help you determine which temperature, from which outdoor
temperature/humidity sensor, you are reading on the indoor display station.
Note: Remove batteries from all existing units in operation—including outdoor
temperature/humidity sensor units and indoor display stations. When setting up
multiple units it is important to insert batteries first into all the outdoor
temperature/humidity sensors, and in numeric sequence. Second install batteries
into the indoor display station. Transmission problems will arise if this is not done
correctly and if the total time for setup exceeds 6 minutes.
A. BATTERY INSTALLATION
Follow these directions when first setting up, when replacing batteries,
or for resetting purposes.
1. Remove the batteries from all existing display units in operation.
2. Using a screwdriver, unscrew and open the battery cover located
at the front of the outdoor temperature/humidity sensor.

Note: Outdoor temperature/humidity sensors will not usually read the
same temperature. This is due to variants such as drafts and handling.
This is normal.
3. Observe the correct polarity and install 2 AA alkaline batteries in
each unit in sequential order. The batteries will fit tightly—make
sure they do not spring free. This may cause start-up problems.
4. Replace the battery cover, screw and mounting bracket.
5. Observing the correct polarity, install batteries into the indoor
display station (refer to the indoor display station’s manual).
Replace battery cover.
6. Wait 15 minutes or until both indoor and outdoor temperature and
humidity are shown on the LCD of the indoor display station.
7. Refer to indoor display station’s instruction manual for more
specific details.
II. MOUNTING
Note: Obstacles such as walls, concrete, and large metal objects can
reduce the effective range of the temperature/humidity sensor. Before
permanently mounting, place units in their desired location to see if a
reading is obtained. There should be a change of temperature in the
OUTDOOR LCD within 6 minutes. If the indoor display station loses
the signal from the outdoor temperature/humidity sensor, it will display
the last temperature reading for 15 minutes. After 15 minutes of not
receiving any signals the OUTDOOR LCD of the indoor display station
will display “- -. –”.
The outdoor temperature/humidity sensor can be mounted in three
ways:
•with the use of screws
•using the adhesive tape
•using the mounting bracket as a stand
A. MOUNTING WITH THE SCREWS
1. Remove the mounting bracket from the outdoor
temperature/humidity sensor.
2. Place mounting bracket over desired location. Through
the 3 screw holes of the bracket, mark the mounting
surface with a pencil.
3. Where marked, drill holes into mounting surface using
an appropriate size drill bit.
4. Screw mounting bracket onto the mounting surface.
Ensure that the screws are flush with the bracket.

5. Snap the outdoor temperature/humidity sensor into
place on the mounting bracket.
B. MOUNTING WITH ADHESIVE TAPE
1. With a nonabrasive solution, clean and dry the back of
the mounting bracket and the mounting surface to
ensure a secure hold. The mounting surface should be
smooth and flat.
2. Remove the protective strip from one side of the tape.
Press firmly into the designated area on the back of the
mounting bracket.
3. Remove the protective strip from the other side of the
tape, and position the outdoor temperature/humidity
sensor in the desired location.
C. MOUNTING USING THE BRACKET AS A STAND
The mounting bracket can be used as a stand by simply attaching
the bracket to the bottom of the temperature/humidity sensor.
Once snapped in place the sensor can then be placed on a shelf,
table or other surface where the temperature and humidity
measurements are desired.
III. MAINTENANCE AND CARE
1. Extreme temperatures, vibrations, and shock should be avoided to
prevent damage to the units
2. Clean displays and units with a soft, damp cloth. Do not use solvents
or scouring agents, they may mark the displays and casings
3. Do not submerge in water.
4. Do not subject the units to unnecessary heat or cold by placing them in
the oven or freezer.
5. Opening the casings invalidates the warranty. Do not try to repair the
unit. Contact La Crosse Technology for repairs.
