*DUAL CHANNEL TRANSMITTER
There is an internal sensor channel and an exter nal probe channel in the transmitter.
Once the temperature transmitter is successfully recognized by the weather station, channel
1 of the weather station will display the temperature data measured by internal sensor and
channel 2 will display the temperature measured by the probe.
If the measuring probe is unplugged, the "probe c hannel" on weather station (channel 2) will
show "---", yet the data from the internal sensor wi ll still be shown on channel 1 .

Dual channel transmitter*: one internal channel
and one probe channel
•

Wall mounting and table stand
This socket is only for the external
probe. Do not apply power plug to it.

The probe can be connected to the remote temperature transmitter any time after initi al
setup. There is no need to reset the units, should the probe be unplugged or re-plugged
again. The weather station will automaticall y detect the temperature probe data and will
display the temperature data on channel 2 after t he probe is plugged.
INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The temperature transmitter uses 2 x AAA, IEC LR3, 1.5V batteries.
To install and replace the batteries, please foll ow the steps below:
1. Remove the battery compartment cover.
2. Insert the batteries, observing the correct pol arity (see marking).
3.
Replace the battery compartment cover.
INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION
The weather station uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the
batteries, please follow the steps below:
46
1. Insert finger or other solid object in the space at the
bottom center of the battery compartment and lift up to
remove the cover.
2. Insert batteries observing the correct polari ty (see
marking).
3. Replace compartment cover.
Battery replacement
•
Replace the batteries when the battery symbol of the weather station appears above
the indoor humidity.
•
When the batteries of the transmitter are used up, the low battery icon appears above
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 security code is assigned by the temperature
47
transmitter at start-up and this code must be received and stored by the weather stati on in
the first 3 minutes of power being supplied to i t.
SETTING UP:
When one temperature transmitter is used:
1. First, insert the batteries into the temperature transmitter (see “Install and replace
batteries in the temperature transmitter” above).
2. Within 30 seconds of powering up the temperat ure transmitter, insert the batteries to
the weather station (see “Install and replace batteries in the weather station”
above). Once the batteries are in place, all segments of the LCD will light up briefly.
Then the indoor temperature and the time as 0:00 will be displayed. If they are not
shown on LCD after 60 seconds, remove the batteries and wait for at least 60
seconds before reinserting them. Once the i ndoor data is displayed, proceed to the
next step.
3. After the batteries are inserted, the weather station will start receiving data signal from
the temperature transmitter.
4. If the optional probe has been plugged to the dual channel transmitter, the outdoor
temperature should then be displayed on the weat her station on channel 1 and 2.
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.
48
Note:
Channel 1 will show the reading from the internal sensor of the dual channel transmitter;
channel 2 will show the reading sensed by the probe. If the probe is not plugged to the
transmitter, " - -" will be shown on channel 2.
5. In order to ensure sufficient 868 MHz transmission, the final position between the
weather station and the temperature transmi tter should not be more than 100 meters
(see notes on “Positioning” and “868 MHz reception”).
6. Once the remote temperature has been recei ved and displayed on the weather
station, the DCF time code reception is automatically started. This takes typically
between 3-5 minutes in good conditions. If the DCF time not received within 10
minutes, press the SET button to adjust the ti me manually.
When two temperature transmitters are used
1. Remove all the batteries from the weather station and temperature transmitters and
wait 60 seconds (if setting has been done wi th one temperature transmitter before).
2. Insert the batteries into the first temperature transmitter.
3. Within 30 seconds of powering up the first temperature transmitter, insert the batteries
into the weather station. Once the batteries are i n place, all segments of the LCD will
light up briefly. Then the indoor temperature and the time as 0:00 will be displayed. If
49
they are not shown on the LCD after 60 seconds, remove the batteries and wait for at
least 60 seconds before reinserting them.
4. If the probe sensor has been installed to the first temperature transmitter, the outdoor
temperature readings from the first temperature transmitter (channel 1 and 2) should
then be displayed on the weather station. 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 into the second temperature transmitter as soon as the outdoor
temperatures from the first temperature transmitter are displayed on the weather
station.
Note: Insert the batteries into the second transmitter within 20 seconds of reception of the
first temperature transmitter.
6. After the weather station has received the seco nd temperature transmitter
successfully, channel 3 will only show the data, which will be measured by the internal
sensor of the second dual channel transmitter. T he measuring data of the external
probe of the second temperature transmitter will not be shown on the display of the
weather station. The outdoor temperature readi ng from the second temperature
transmitter will be shown on the display of the weather station and the shown channel
number will be shift back to “1”, to indicate that all three channels are running
successfully. If this does not happen within 2 mi nutes, the batteries will need to be
50
removed from all the units and reset from step 1.
6. Once the external data has been received and di splayed on the weather station, the
DCF time code reception is automatically started. This takes typically between 3-5
minutes in good conditions.
NOTE FOR RADIO-CONTROLLED TIME DCF:
The time base for the radio-controlled time i s a caesium atomic clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig. It has a time deviation of less than
one second in one million years. The time i s 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 radio-controll ed clock receives this signal and converts it to
show the precise time. Changeover from summer time or winter time is automatic. The
quality of the reception depends mainly on the geographic location. Normally there should
be no reception problems within a 1,500 km radius around Frankfurt.
DCF reception is done twice daily at 02:00 and 03:00 am. If the reception is not successful
at 03:00 am, then the next reception takes pl ace the next hour and so on until 06:00am, or
until the reception is successful. If the recepti on is not successful at 06:00 am, then the ne xt
attempt will take place the next day at 02:00 am.
