Battery replacement
•
•
Replace the batteries when the battery symbol of
the temperature station appears near the indoor
temperature display.
When the batteries of the transmitter are used up,
the low battery icon appears near the outdoor
temperature display.
Note:
In the event of changing batteries in any of the units, all
units need to be reset by following the setting up
procedures. This is because a random security code is
assigned by the transmitter at start-up and this code must
be received and stored by the temperature station in the
first three minutes of power being supplied to it.
37
SETTING UP:
WHEN ONE TRANSMITTER IS USED
1.
First, insert the batteries in the transmitter
(see “How to install and replace batteries
in the temperature transmitter” below).
2.
Within 2 minutes of powering up the
transmitter, insert the batteries in 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/humidity and the time as 0:00
will be displayed. If these information are
not displayed on the LCD after 60 seconds,
remove the batteries and wait for at least 60
seconds before reinserting them. Once the
indoor data 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 transmitter. The outdoor
temperature data (channel 1 and 2) 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 868 MHz transmission
however, the distance between the temperature
station and the transmitter should not be more than
100 meters (see notes on “Positioning” and “868
MHz Reception”).
38
Note:
In the event of changing batteries of the units, ensure the
batteries do not spring free from the contacts. Always wait
at least 1 minute after removing the batteries before
reinserting, otherwise start up and transmission problems
may occur.
OPTIONAL CHANNEL 2 TEMPERATURE PROBE
When the temperature probe is connected to the
temperature transmitter, the temperature station will
always display the outdoor temperature transmitter data in
channel 1, and the temperature recorded from the probe
in channel 2.
If the probe on remote temperature sensor is
unplugged, the "probe channel" will show "---", the
temperature data from the transmitter will still be
displayed.
The temperature probe can be connected to the
temperature transmitter anytime. There is no need to
reset the units. The temperature station will automatically
detect the temperature probe and will display the
temperature probe data in channel 2.
WHEN MORE THAN ONE TRANSMITTER IS USED
1.
User shall remove all the batteries from the
Temperature Station and transmitters, and wait 60
seconds.
2.
Insert the batteries in the first transmitter.
3.
Within 2 minutes of powering up the first
transmitter, insert the batteries in the Temperature
Station. Once the batteries are in place, all
segments of the LCD will light up briefly. Following
the indoor temperature/humidity and the time as
0:00 will be displayed. If these information are not
displayed on the LCD after 60 seconds, remove the
batteries from both units and wait for at least 60

seconds before reinserting them.
The outdoor temperature data from the first
transmitter (channel 1 and 2) 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.
If the temperature probe has been used, the
outdoor temperature from channel 2 will then be
displayed. Otherwise, the outdoor temperature will
display “---“.
Note: The temperature probe from the first sensor
will always occupy “channel 2”. Channel 2 can
only be used for the temperature probe. If you
choose not to use the temperature probe, channel
2 will display “---“.
Insert the batteries in the second transmitter as
soon as the outdoor temperature readings from the
first transmitter are displayed on the Temperature
Station.
Note : User shall insert the batteries into the
second transmitter within 45 seconds after the
temperature station displays the information of the
first transmitter. Or immediately after reception of
the first transmitter is finished
The outdoor temperature from the second
transmitter and the "channel 3" 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.
In order to ensure sufficient 868 MHz transmission
however, the distance between the temperature
station and the transmitter should not be more than
40
100 meters (see notes on “Positioning” and “868
MHz Reception”).
DCF-77 RADIO CONTROLLED TIME
The time base for the radio-controlled time is a Cesium
Atomic Clock operated by the Physikalisch Technische
Bundesanstalt Braunschweig which has a time deviation
of less than one second in one million years. The time is
coded and transmitted from Mainflingen near Frankfurt via
frequency signal DCF-77 (77.5 kHz) and has a
transmitting range of approximately 1,500 km. Your radiocontrolled temperature station receives this signal and
converts it to show the precise time in summer or
wintertime. The quality of the reception depends greatly
on the geographic location. In normal cases, there should
be no reception problems within a 1500km radius of
Frankfurt.
Once the outdoor temperature is displayed on the
temperature station, the DCF tower icon in the clock
display will start flashing in the upper left corner. This
indicates that the clock has detected that there is a radio
signal present and is trying to receive it. When the time
code is received, the DCF tower becomes permanently lit
and the time will be displayed.
DCF reception is done twice daily at 02:00 and 03:00 am.
If the reception is not successful at 02:00 am, then the
next reception takes place the next hour and so on until
06:00am, or until the reception is successful. If the
reception is not successful at 06:00 am, then the next
attempt will take place the next day at 02:00 am.
If the tower icon flashes, but does not set the time or the
DCF tower does not appear at all, then please take note
of the following:
41
•
•
•
Recommended distance to any interfering sources
like computer monitors or TV sets is a minimum of
1.5 - 2 meters.
Within ferro-concrete rooms (basements,
superstructures), the received signal is naturally
weakened. In extreme cases, please place the unit
close to a window and/ or point its front or back
towards the Frankfurt transmitter.
During nighttime, the atmospheric disturbances are
usually less severe and reception is possible in
most cases. A single daily reception is adequate to
keep the accuracy deviation below 1 second.

TEMPERATURE TRANSMITTER
The outdoor temperature is measured and transmitted
every 4 seconds.
The range of the temperature transmitter may be affected
by the temperature. At cold temperatures the transmitting
52
distance may be decreased. Please bear this in mind
when placing the transmitter.
868 MHz RECEPTION:
If the outdoor temperature data is not being received
within three minutes after setting up (or outdoor display
always show “- -. -” in the outdoor section of the
temperature station during normal operation), please
check the following points:
1.
The distance of the temperature station or
transmitter should be at least 1.5 to 2 meters away
from any interfering sources such as computer
monitors or TV sets.
2.
Avoid placing the receiver onto or in the immediate
proximity of metal window frames.
3.
Using other electrical products such as
headphones or speakers operating on the same
signal frequency (868MHz) may prevent correct
signal transmission and reception.
4.
Neighbors using electrical devices operating on
the 868 MHz signal frequency can also cause
interference.
Note:
When the 868MHz signal is received correctly, do not reopen the battery covers of either the transmitter or
Temperature Station, as the batteries may spring free
from the contacts and force a false reset. Should this
happen accidentally then reset all units (see Setting up
above) otherwise transmission problems may occur.
The transmission range is about 100 m from the
transmitter to the temperature station (in open space).
However, this depends on the surrounding environment
and interference levels. If no reception is possible despite
the observation of these factors, all system units have to
be reset (see Setting up).
53
POSITIONING THE TEMPERATURE STATION:
The temperature station has been designed to be hang on
a wall or free standing.
For free standing:
Pull out the easel on the back of the
unit and place onto a flat surface.
To wall mount
Choose a sheltered place. Avoid direct rain and sunshine.
Before wall mounting, please check that the outdoor
temperature values can be received from the desired
locations. To wall mount:
1.
Fix a screw (not supplied) into
the desired wall, leaving the head
extended out the by about 5mm.
2.
Fold the stand of the temperature
station by pushing inward and
hang it onto the screw.
Remember to ensure that it locks
into place before releasing.
POSITIONING THE OUTDOOR TEMPERATURE
TRANSMITTER
The sensor is supplied with a holder
that may be attached to a wall with the
two screws supplied.
The transmitter can also be position on
a flat surface by securing the stand to
the bottom to the transmitter.
54
To wall mount:
1.
2.
3.
Mark the wall using a pen
through the holes in the
holder to obtain the exact
drilling position.
Drill holes in the wall at the
points marked.
Screw holder onto wall.
Note:
Before permanently fixing the transmitter wall base, place
all units in the desired locations to check that the outdoor
readings are receivable. In event that the signal is not
received, relocate the transmitter(s) or move them slightly
as this may help the signal reception.
There is also double sided tape included with the wall
mount. On smooth surfaces this can be used instead of
drilling holes. The mounting surface can, however, affect
the transmission range. If for example the unit is attached
to a piece of metal, it may then either reduce or increase
the transmitting range. For this reason, we recommend
not placing the unit on any metal surfaces or in any
position where a large metal or highly polished surface is
in the immediate proximity (garage doors, double glazing,
etc.). Before securing in place, please ensure that the
Temperature station can receive the 868MHz signal from
the transmitter at the positions that you wish to situate
them.
The transmitter simply clicks in or out of the holder. When
inserting or removing the transmitter from the wall holder
please hold both units securely.
