5. Setting up:
Activating the Receiver:
1. Flip open the battery cover located at the back of the receiver and
checking the correct polarization, insert 2 x AA 1.5V batteries into the
battery compartment before replacing the cover
2. Once the batteries are inserted, all the LCD segments will light up
briefly before displaying individual sets of data
3. Within 4 minutes of activating the receiver, activate the sensor(s) as
follows
Activating the Sensor(s):
1. Using a screwdriver, unscrew and open the battery cover located at
the front of the sensor and checking the correct polarization insert 2 x
AA 1.5V batteries into the battery compartment before replacing the
cover
2. Once the batteries are inserted, the LCD on the sensor will show the
surrounding temperature and humidity and start transmitting the data
to the receiver by 433MHz
3. Now check the outdoor temperature and outdoor humidity from
sensor has been received on the LCD of the receiver in the outdoor
data section
4. Once the data is received from the first sensor, activate the second
and then followed by the third sensors in the same way (the number
of sensors depends on the set that you have purchased from your
local dealer). After each data reception from a sensor, a channel
number for that sensor will be displayed on the receiver’s LCD to
show the data reception was successful. When all three sensors are
operable, the channel key is used to toggle between channels 1, 2
and 3 to display the relevant data from each of the sensors. During
signal transmission the high frequency icon can be seen above the
channel icons to show that data transmission is taking place.

Important Note:
During setting up, it is important to distinguish which sensor is ‘sensor 1’,
‘sensor 2’ and ‘sensor 3’ for final place of fixing. Distinguishing the
sensors will allow the user to position the sensors in the location of
choice. For example the user may want to affix ‘sensor 1’ outdoors,
‘sensor 2’ in the garage and ‘sensor 3’ in the greenhouse and once the
readings are displayed on the receiver’s LCD the user will know which
channel corresponds to location of the sensors.
It is also important to distinguish which is ‘sensor 1’ as this one sensor is
used for the snowfall indicator when the temperature level falls to 0°C or
below and therefore must be positioned outdoors. Note that this feature
only applies to the first activated sensor and does not apply to the other
sensors even if all of them are activated for use.
Once all sensor(s) signals are received, the receiver will start to receive
the DCF77 radio controlled time signal. Once the time signal is received
the time and calendar will automatically be displayed in the time section
on the LCD.
6. How to use the Weather Station:
This section will describe how to interpret the data as shown on the LCD
of the Weather Station. For easy reference, the LCD shown here is in

1. The ‘TEMP/HYGRO OUT’ section will display the outdoor
temperature and outdoor humidity of any one of up three thermo-
hygro sensors. Use the channel key to toggle between sensors 1, 2
and 3 (sensors are optional from your dealer).
2. MIN/MAX function, with each press of the min/max key the LCD will
toggle through:
•Maximum outdoor temperature
•Minimum outdoor temperature
•Maximum outdoor humidity
•Minimum outdoor humidity
•Maximum indoor temperature
•Minimum indoor temperature
•Maximum indoor humidity
•Minimum indoor humidity
When each respective maximum and minimum record is displayed,
the times and dates at which the records were received will be
flashing. The LCD will automatically return to the normal operation
mode after 15 seconds.
3. The high frequency transmission icon will appear each time the
sensor is transmitting out new data to the weather station
4. Channel’s 1, 2 and 3 icons represent the respective sensor being
displayed on the LCD at that moment in time. Only data from one
channel can be displayed at any one moment in time. Use the
channel key to toggle between each of the sensors.
5. The storm-warning indicator (windsock icon) works in two steps and
appears when there is an expected storm or poor weather. The first
step is for moderate wind where air pressure falling by more than
4hPa or if the air pressure falls below 995hPa within a 6-hour period,
the windsock is displayed slightly raised from the mast. The second
step indicates strong winds and possible stormy weather where the
windsock is raised horizontally from the mast. The stronger signal
appears when the air pressure falls by more than 5hPa within a 4-
hour period or if the air pressure falls to below 990hPa. The
moderate storm-warning indicator will stop when the air pressure has
risen by 1 hPa or if the air pressure rises to more than 995hPa. The
stronger storm-warning indicator will stop when the air pressure rises
by 1hPa or if the air pressure rises to more than 990hPa.
6. The electronic barometer has three weather icons, raining, cloudy
and sunny for weather forecasting. This feature allows this
instrument to be used as an analog barometer to easily check
periods of high air pressure (above 1013 hPa) or periods of low air
pressure (below 1013 hPa). The smaller circles surrounding the air
pressure bar graph functions as a bar and represents the air
pressure in a clockwise direction for increasing air pressure and anti-
clockwise for decreasing air pressure. Each circle (segment) is
equal to 1.5 hPa with the default air pressure setting at 1013 hPa,
the circle bar is set to the middle of the circle for cloudy icon. Until
the unit has run for at least 24 hours, weather forecasts given should
be discarded to allow the unit sufficient time for air pressure reading
at a consistent altitude to provide more accurate readings. The
higher the air pressure, the more circles will appear and the better
the weather is expected to be. The lower the air pressure, the fewer
the circles will appear meaning the weather is expected to become
worse. The weather icons are used as points of reference for the
barometer bar of circles that run around the main air pressure bar
graph. For best results and accurate readings, the unit should
operate constantly at the point of fixing. Common to weather
forecasting, absolute accuracy cannot be guaranteed but it will give
users an indication of the expected weather.
7. The unique weather history feature allows the user to select a time
interval to record up to 170 sets of weather history data. A set of
data consists of the outdoor temperature, outdoor humidity, indoor
temperature, indoor humidity, air pressure and the associated time
and date that these readings were recorded. For the outdoor data,
only history from sensor 1 will be recorded. When the history feature
is used the circle bar of the barometer for weather forecasting also
changes. To recall the data, press the history key once and then
using the ‘+’ or ‘–‘ keys to move forward or backwards or
alternatively press and hold the ‘+’ or ‘–‘ keys to scroll through the
data in fast forward and backward mode. To select the desired time
recording interval for weather history, go to the interval setting in the
‘User setting mode’.
8. The weather tendency indicator is located on the right side of the air
pressure bar graph. The indicator is split into four parts, two
indicators pointing upwards and two indicators pointing downwards.
When either one of the up or down indicators are displayed, it means
that there is a moderate change in the air pressure by more than

GB
GB
1hPa but less than 3hPa within a 4-hour period. When either both
the up or both the down indicators are displayed at any one time, it
means a significant change in the air pressure has occurred by more
than 3hPa within a 4-hour period. The indicator pointing upwards
represents an increase in the air pressure and the weather is
expected to improve. When the indicator points downwards, it
represents a drop in air pressure and the weather is expected to
become worse.
9. The air pressure bar graph indicates the air pressure trend over the
past 12 hours with each bar along the horizontal axis representing 1
hour. The middle of the vertical axis (point at where the up and
down tendency indicators intersect) represents the current air
pressure and each single bar change on the vertical axis is how high
or low in 2hPa the past pressure was compared to the current
pressure. If the bars are rising it means that the weather is
improving due to the increase in air pressure. If the bars go down, it
means the air pressure has dropped and the weather is expected to
become worse.
10. The snowfall indicator is represented by the cloud and snowflake
icon (positioned over the raining icon) when the temperature of
‘sensor 1’ falls to 0°C or below. Note that this feature only applies to
‘sensor 1’. ‘Sensor 1’ is the first activated sensor and does not apply
to any of the other sensors even if they are activated. For accurate
operation of this feature, ensure that ‘sensor 1’ is positioned
outdoors in an appropriate place but away from direct sunlight and
rain to avoid inaccurate data measurements.
11. Relative air pressure is the one value that is calculated back at sea
level from the local absolute air pressure and can thus be used for
reference for weather conditions and weather developments for your
area. Since the relative air pressure is the one value given by the
various TV, radio stations in their daily weather reports for their
respective locations it is recommended to use this value to correct
the default value on this weather station to represent your local area.
12. Low battery indicator will appear when the batteries are near
exhaustion and require replacing. When alkaline batteries are used
in the weather station and the sensor(s), battery life is approximately
12 months. When changing batteries, batteries to all units should be
changed at the same time to maintain optimum operation.
13. ‘TIME/DATE’. In this section, the time and calendar is displayed.
The time and date will synchronize to the DCF77 radio controlled
time signal or it can be manually set to function like a normal clock.
The time signal is received once daily from 0200 to 0600 hours (2
a.m. to 6 a.m.) or if signal reception is unsuccessful in the first
attempt it will try to receive the signal each hour during these times.
Signal reception is also attempted each time the weather station
exits the user setting mode if the time or date has been manually
changed (unless the RCC feature is set to ‘Off’). The received time
also functions as the time base of all recorded data for the weather
history. During signal reception the RCC tower icon flashes on the
LCD to show that reception is taking place and will remain visual
once the signal is received. The DCF77 radio controlled time and
calendar display is based on the signal provided by the Caesium
atomic clock operated by the Physikalisch Technische Bundesamt in
Braunschweig, Germany.
14. ‘TEMP/HYGRO IN’. In this section, the indoor temperature and
indoor relative humidity surrounding the receiver is displayed.
7. User Setting mode:
