Remote Temperature Display

By using RF technology and simple Learn function, the Weather
Station can receive remote signals from up to 4 Remote
Transmitters (WT260) which can be placed indoor / outdoor
wherever you desire within the transmission range.
To enable the Weather Station to receive signals from each Remote
Transmitter, identical House Code and different Channel Numbers
must be assigned to each Remote Transmitter in use. Please follow
the procedures below to set the Remote Transmitter(s) to work with
the Weather Station.

Setting the Remote Transmitter(s)

There are 2 buttons at the back of transmitter. Press the RESET
button (right side) to start the setting procedure.
House Code will be flashing with "01" as in Figure 7. If desired,
press SET button (left side) to change the House Code.
The range of House Codes are from "01" to "15". Make sure all
transmitters in your system are set to the same House Code.
The House Code will be confirmed if no key is pressed for 12
seconds.Channel Number will start to flash with "1" as in Figure 8.

FIGURE 7

Use the SET button to select different Channel Number (1- 4) for
each of your transmitter.
The Channel Number will be confirmed if no key is pressed for 12
seconds. The current temperature will start to flash.
Use the SET button to change between °C to °F if desired.

FIGURE 8

The Setting mode will end after no key is pressed for 12 seconds.
During the setting process, you may press the RESET button
anytime to restart the setting process. After initial setting, please do
not press the 2 buttons again. Otherwise the Learn procedure of
the receiver will need to be repeated.
After setting, the current temperature and humidity (WT260H only)
will be displayed. The data will then be transmitted to the receiver
every minute (Figure 9).

Setting the Weather Station as Receiver

18.7 C

The Weather Station needs to execute the Learn function to identify
the transmitters present and their transmission sequence. To start
the Learn function, press and hold SNOOZE for 3 seconds. "RF
THERMO" symbol will flash and a beep sound will indicate that the
Learn function has been activated.
The Weather Station will search for signals from Transmitter(s)
nearby and use the first House Code received as its own House
Code.
Whenever a valid data is received, a beep will sound and the
temperature and channel number will be displayed on the Right
Display Box of the Weather Station as in Figure 10.

C C

The Learn process will last for about 3 minutes.
Whenever the setting of transmitter is changed or the battery of
either transmitter or receiver is replaced, the Learn process needs to
be executed again.

To scroll through the displays of Current Temperature, Maximum
Temperature and Minimum Temperature from the Transmitter,
press the SNOOZE key.
If the remote temperature display starts to flash, it indicates that
the signal is temporary lost. This may be due to interference from
nearby electrical appliances or environment. You can wait for a
while to see if the flashing will stop because most interference is
temporary.
Sometimes the signal received is too weak and you can try to move
the Weather Station and/or Transmitter to a different location to
have better reception of the signals. Flashing will stop once the
signal is received by the Weather Station again.
However, if flashing does not stop, it indicates that the Weather
Station cannot receive signals from the Transmitter and the Learn
function must be activated again.

Selecting the Temperature/ Humidity Display
Combinations on Weather Station

1. Initially, local data is displayed on the left display box and
remote data is displayed on the right.

2. By using CHANNEL key you can change the display of either box.

3. Left box - Press and hold CHANNEL for 3 seconds to scroll
through the following display modes:

Local CH.1 CH.2 CH.3 CH.4 Local

The symbol "LOCAL" will light up to indicate display of local
temperature while the Channel Number under the Display
Box will light up to indicate display of data from such Channel. To
choose a particular display, release the CHANNEL key when such
data is being shown.
While CHANNEL is held, the House Code of the Weather Station
will be displayed on the Upper Display Area (Figure 11).

seconds.

5. If Left and Right boxes are set to the same channel and humidity
data is available on that channel, then temperature will be displayed
on the left box and humidity on the right box.

6. Whenever the Learn function is activated again, both Display boxes
will return to their default displays.

Important Notes:

Transmissions of signals may be affected by external factors like
atmospheric disturbance, extreme temperature or magnetic field
emitted by electrical appliances nearby.

If the remote temperature is not displayed on the Weather Station within 2
minutes after setting up, it is advised to relocate the positions of the devices
or move the devices away from other electrical appliances as they may be
subject to interference. If the problem persists, reset both devices again.

Low Battery Indication

Weather Station - indicated by the flashing "LOCAL" symbol below the
Left box.
Remote Transmitter - indicated by the flashing Channel Number on the
Weather Station; and "Lo bat" also appears periodically on the display
of the Transmitter as in Figure 13.

In each case, batteries should be replaced. After installation of new
batteries, the set up procedure will need to be performed again.

FIGURE 13

Wall-Mounting for Remote Transmitters

With the wall-mount holder, the Transmitters can be attached onto the
wall easily by following the procedures below:

Choose a location within the transmission range where you wish to
place the Transmitter. Avoid locations too close to metallic objects.
Check if the data from Remote Transmitter can be received by the
Weather Station from each of the selected locations.
Then, mark the 2 screw positions on the wall through the holes of
the holder with a pen.
Drill holes into the wall at the marked positions.
Attach the Holder onto the wall by the provided screws.
Slide the Transmitter into the Holder until a clicking sound is
heard.
Alternatively, you can simply attach the Holder onto the wall by
using double-sided adhesive tape.

Maintenance

To avoid damage to the device, do not place the Weather Station
or Transmitter in places where there is a risk of vibration or shock.
Keep the Weather Station away from moisture and water.
For both the Weather Station and the Transmitter, use batteries of
recommended size only.

Error/ Abnormal Display

When there is an abnormal display or malfunction (e.g., the Weather
Station is unable to learn and display the data from the Transmitter(s)),
replace the batteries and re-set both the Weather Station and the
Transmitter(s) again.
