DETAILED SETUP GUIDE

I. BATTERY INSTALLATION

A. REMOTE CONTROL SENDER

Battery compartment

1. Remove the mounting bracket.

The bracket snaps on and off with
minimal effort.

2. Remove battery cover. To do this,

remove the flathead screw located
in the lower-central position of the
unit. The rubber weather-seal
creates a tight seal for the battery
cover, and does not allow the

Battery cover

3

battery cover to fall away from the
unit. Place the screw partially
back into the hole and angle it
slightly, so the threads grab the
battery cover. With the screw,
pull the battery cover off.

3. Observing the correct polarity,

install 2 AAA batteries. The
batteries will fit tightly—make
sure they do not spring free, or
start-up problems may occur.

4. Check the LCD screen of the

Remote Control Sender to see if
there is a temperature reading. If
there is no reading check the
polarity of the batteries or replace
with new batteries.

5. Observing that the rubber

weather-seal is in place; replace
battery cover, screw, and
mounting bracket.

B. INDOOR TEMPERATURE

STATION

After the batteries are installed, DO

Note:
NOT press any buttons. This may interfere

with the signals, causing temperatures to
register incorrectly.

displayed in the OUTDOOR LCD.

1. Ï Indicates that the temperature

is rising.

2. Ð Indicates that the temperature

is dropping.

3. The absence of an arrow indicates

that the temperature is stable.

VII. MOUNTING

A. THE REMOTE CONTROL

SENDER

To achieve a true temperature

Note:

reading, avoid mounting where direct
sunlight can reach the Remote Control
Sender. We recommend that you mount
the Sender on a North-facing wall. The
sending range is 80ft; obstacles such as

13

walls, concrete, and large metal objects can
reduce the range. Place both units in their
desired location before permanently
mounting the Remote Control Sender.
There should be a change of temperature in
the OUTDOOR LCD within 6 minutes.

The Remote Control Sender can be mounted in
two ways:

• with the use of screws or,

• using the adhesive tape.

1. MOUNTING WITH THE

SCREWS

a) Remove the mounting bracket

from the Remote Control
Sender (figure 2).

b) Place mounting bracket over

desired location. Through the
three screw holes of the
bracket, mark the mounting
surface with a pencil.

14

c) Where marked, drill holes

into mounting surface using
an appropriate size drill bit.

d) Screw mounting bracket onto

the mounting surface. Ensure
that the screws are flush with
the bracket.

2. MOUNTING WITH

ADHESIVE TAPE

a) 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.

b) Remove the protective strip

from one side of the tape.
Adhere the tape to the
designated area on the back of
the mounting bracket.

15

c) Remove the protective strip

from the other side of the
tape. Position the Remote
Control Sender in the desired
location, ensuring that the
Indoor Temperature Station
can receive the signal.

B. THE INDOOR TEMPERATURE

STATION

Before mounting the Indoor

Note:

Temperature Station make sure that it is
able to receive signals from the Remote
Control Sender.

The Indoor Temperature Station can also
be mounted in two ways:

• with the table stand or,

• on the wall with the use of a wall

hanging screw (not included).

16

1. USING THE TABLE-STAND
a) The Indoor Temperature

Station comes with the table
stand already mounted. If
you wish to use the table­stand all that is required is to
place the Indoor Temperature
Station in an appropriate
location.

2. WALL MOUNTING

17

a) Remove the table stand. To

do this, pull down on the
stand from the rear and rotate
forward.

b) Fix a screw (not included)

into the desired wall, leaving
approximately 3/16 of an inch
(5mm) extended from the
wall.

c) Place the Indoor Temperature

Station onto the screw using
the hanging hole on the
backside. Gently pull the
Station down to lock the
screw into place.

VIII. USING MULTIPLE REMOTE

CONTROL SENDERS

Your WS-7054U Indoor Temperature Station
can receive signals from five different Remote
Control Senders (The TX3U features
temperature data transmission and the TX3UP

18

offers the same plus a 10’ probe to insert in a
pool, spa, soil, etc.). Assign a number to each
Remote Control Sender (i.e. #1 will be for
outdoors, #2 will be for the basement, etc.).
This will help you determine which
temperature, from which Sender, you are
reading on the Indoor Temperature Station.

When setting up multiple units it is

Note:

important to insert batteries first into all the
Remote Control Senders, and in numeric
sequence. Second install batteries into the
Indoor Temperature Station. Transmission
problems will arise if this is not done correctly
and if the total time for set-up exceeds 6
minutes.

19

A. SETUP OF MULTIPLE UNITS

1. It is necessary to remove the
batteries from all existing units in
operation.

2. Remove the battery covers to all
Remote Control Senders. See
section I.A.2.

3. Place all Remote Control Senders
in sequential order.

#1 #2 #3

4. In sequential order, install
batteries. (Refer to instructions in
I.A.3 through I.A.5).

20

5. Install batteries into the Indoor
Temperature Station. (Refer to
instructions in I.B.).

6. Follow directions in section II.A
to set the time, section III.A to
select Fahrenheit or Celsius, and
section VII. A to mount.

B. VIEWING MULTIPLE REMOTE

CONTROL SENDERS ON THE
INDOOR TEMPERATURE
STATION

1. To view the temperature of a
different Remote Control Sender,
press the RESET button.

2. In the OUTDOOR LCD a

should shift and become a

3. Repeat step 1 to view the 3

th

(depending on how many

and 5

, 4th,

are set up) temperatures sent by
the Remote Control Senders.
Continue to press RESET until you
return to the first Remote Control
Sender.

C. VIEWING THE FEATURES OF

MULTIPLE REMOTE CONTROL
SENDERS

1. Press the RESET button to select
the Remote Control Sender you
wish to view.

2. To view the OUTDOOR
MINIMUM AND MAXIMUM
TEMPERATURES, follow
directions in section IV.B. While,
in this mode press the RESET
button to toggle through different
Remote Control Senders and view

22

their minimum and maximum
temperatures.

3. To reset the OUTDOOR
MINIMUM AND MAXIMUM
TEMPERATURES, follow step 1
above and the directions in
sections V.A. through V.B. This
will reset the minimum and
maximum for only the selected
Remote Control Sender.
