The Temperature Station
•Indoor and outdoor temperature reading in Fahrenheit (°F) or
Celsius (°C)
•Can receive up to three outdoor sensors
•Wireless transmission at 915 MHz
•Signal reception intervals at 16 seconds
•Minimum and Maximum records of indoor and outdoor
temperature
•Low battery indicator
•Wall hanging or free standing (removable table stand included)

6
The Outdoor Temperature Sensor
•Remote transmission of outdoor
temperature to Temperature Station by
915 MHz transmission
•Water resistant casing
•Wall hanging or free standing

SETTING UP:
When one sensor is used
1. First, insert the batteries to the sensor (see “How to install and
replace batteries in the temperature sensor”below).
2. Within 30 seconds of powering up the sensor, insert the batteries
to the Temperature Station (see “How to install and replace
batteries in the Temperature Station”below). Once the
batteries are in place, all segments of the LCD will light up briefly.
Following the indoor temperature will be displayed. If this is not
shown in LCD after 60 seconds, remove the batteries and wait for
at least 60 seconds before reinserting them. Once the indoor data

8
is displayed user may proceed to the next step.
3. After the batteries are inserted, the Temperature Station will start
receiving data signal from the sensor. The outdoor temperature
should then be displayed on the Temperature Station. If this does
not happen after 2 minutes, the batteries will need to be removed
from both units and reset from step 1.
4. In order to ensure sufficient 915 MHz transmission however, there
should be a distance of no more than 330 feet between the final
position of the Temperature Station and the sensor (see notes on
“Positioning” and “915 MHz Reception”).

9
Using Multiple Sensors with One Temperature Station
1. User shall remove all the batteries from the Temperature Station
and sensors and wait 60 seconds if setting has been done with one
sensor before.
2. Insert the batteries to the first sensor.
3. Within 30 seconds of powering up the first sensor, insert the
batteries to the Temperature Station. Once the batteries are in
place, all segments of the LCD will light up briefly. Following the
indoor temperature will be displayed. If this is not shown in LCD
after 60 seconds, remove the batteries and wait for at least 60
seconds before reinserting them.

4. The outdoor temperature from the first sensor (channel 1) should
then be displayed on the Temperature Station. Also, the signal
reception icon will be displayed. If this does not happen after 2
minutes, the batteries will need to be removed from both units and
reset from step 1.
5. Insert the batteries to the second sensor immediate after (within 10
seconds) inserting battery to the temperature station.
6. The outdoor temperature from the second sensor and the "channel
2" icon should then be displayed on the Temperature Station. If this
does not happen after 2 minutes, the batteries will need to be
removed from all the units and reset from step 1.

11
7. Insert the batteries to the third sensor immediate after (in 10
seconds after) inserting battery to the second sensor.
8. Then within 2 minutes, the channel 3 outdoor data from the third
sensor will be displayed and the channel icon will shift back to "1"
once the third sensor is successfully received. If this is not happen,
user shall restart the setting up from step 1.
9. In order to ensure sufficient 915 MHz transmission there should be
no more than 330 feet (100 meters) between the final position of
the Temperature Station and the sensor (see notes on
“Positioning” and “915 MHz Reception”).
Note:

12
After the three sensors have been set up, user may need to check the
readings displayed on the temperature station against those being shown
on the sensor displays, in order to recognize on which channel each
sensor is being presented.
IMPORTANT:
Transmission problems will arise if the setting for additional sensors is not
followed as described above. Should transmission problems occur, it is
necessary to remove the batteries from all units and start again the set-up
from step 1.

HOW TO INSTALL AND REPLACE BATTERIES IN THE
TEMPERATURE STATION
The Temperature Station uses 2 x AAA, Alkaline
batteries. When batteries will need to be replaced,
the low battery icon will appear on the LCD. To
install and replace the batteries, please follow the
steps below:
1. Lift up the battery compartment cover.
2. Insert batteries observing the correct polarity
(see marking).
3. Replace compartment cover.

14
HOW TO INSTALL AND REPLACE BATTERIES IN THE
TEMPERATURE SENSOR
The temperature sensor uses 1 x CR2032, 3.0V battery. When battery
needs to be replaced, the low battery icon will appear on the LCD of the
Temperature Station-or replace battery every 12 months. To install and
replace the batteries, please follow the steps below:
1. Pull out the battery holder at the bottom of the sensor.
2. Insert the batteries, observing the correct polarity (see
marking).
3. Replace the battery holder on the unit.

15
Note:
In the event of changing batteries in any of the units, all units need to be
reset by following the setup procedures. This is because a random
security code is assigned by the sensor at start-up and this code must be
received and stored by the Temperature Station in the first few minutes of
power supplying.
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure
optimum accuracy of these units. (Battery life - see Specifications)

16
Please participate in the preservation of the
environment. Return used batteries to an authorized
depot.
FUNCTION KEYS
Temperature Station:
The Temperature Station has two easy to use function keys.

17
SET/CH key (Setting/Channel)
•Press and hold for about 3 seconds to toggle between the
temperature units (°F) or (°C).
MIN/ MAX/ + key
SET/ CH key

18
•Press shortly to toggle between different channel readings.
MIN/MAX/+ key (Min/ Max temperature)
•Use to toggle between the minimum and maximum recorded
readings of indoor & outdoor temperature.
•Press and hold to reset minimum and maximum record (when min
or max record is shown).

*When the signal from the sensor is successfully received by the
Temperature Station, this icon will be switched on. (If not successful, the
icon will not be shown on the LCD). User can therefore easily see
whether the last reception was successful (“ON” icon) or not (“OFF” icon).
On the other hand, the short blinking of the icon shows that a reception is
being done at that time.
For a better display clarity, the LCD screen is split into 2 sections,
showing the indoor and outdoor temperatures.

•Display of indoor temperature.
