TX4U Outdoor Temperature/Humidity Sensor
The TX4U 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 units
in operation.
2. Remove the battery covers to all outdoor
temperature/humidity sensors. Simply slide
the battery cover down to remove.
3. Place outdoor temperature/humidity sensors
in sequential order.
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.
1. 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.
2. Replace the battery cover, rain protector,
and mounting brackets.
3. Observing the correct polarity, install
batteries into the indoor display station
(refer to the indoor display station’s
manual). Replace battery cover.
4. Wait 5-6 minutes or until both indoor and
outdoor temperature and humidity are
shown on the LCD of the indoor display
station.
5. Refer to indoor display station’s instruction
manual for more specific details.
II. MOUNTING
Note: The sending range of the outdoor
temperature/humidity sensor is 80 ft. However,
obstacles such as walls, concrete, and large
metal objects can reduce the range. 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 two ways:
•
with the use of screws or,
•
using the adhesive tape.
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.
