TO INSTALL AND REPLACE BATTERIES IN THE THERMO­HYGRO TRANSMITTER

The outdoor thermo-hygro transmitter uses 2 x AA IEC
LR6, 1.5V batteries. To install and replace the batteries,
please follow the steps below:

1. Remove the battery cover at the front side with a
small screwdriver.

2. Insert the batteries, observing the correct polarity
(see battery compartment marking).

3. Replace the battery cover on the unit.

HOW TO INSTALL AND REPLACE BATTERIES IN THE
THERMO-HYGRO-STATION

The thermo-hygro-station uses 3 x AA, IEC LR6, 1.5V batteries. To install
and replace the batteries, please follow the steps below:

Battery replacement

•

Replace the batteries when the battery symbol of the temperature
station appears near the indoor data display.

•

When the batteries of the transmitter are used up, the low battery
icon appears near the outdoor data 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 due to a random
security code assigned by the transmitter at start-up. This code must be
received and stored by the thermo-hygro-station in the first 3 minutes of
power being supplied to the transmitter.

1. Insert finger or other solid object in
the space at the top center of the
battery compartment and lift up to
remove the cover.

2. Insert batteries observing the correct
polarity (see marking).

3. Replace compartment cover.

SETTING UP:

WHEN ONE TRANSMITTER IS USED

1. First, insert the batteries in the transmitter (see “How to install and
replace batteries in the thermo-hygro outdoor transmitter”

above).

2. Within 2 minutes of powering up the transmitter, insert the batteries
in the thermo-hygro-station (see “How to install and replace
batteries in the thermo-hygro-station” above). 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 this information is not displayed on the LCD after 60
seconds, remove the batteries and wait for at least 60 seconds

26

before reinserting them. Once the indoor data is displayed user ma y
proceed to the next step.

3. After the batteries are inserted, the thermo-hygro-station will start
receiving data signal from the transmitter. The outdoor temperature
and humidity data should then be displayed on the thermo-hygro­station. 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 thermo-hygro-station and the transmitter
should not be more than 100 meters (see notes on “Positioning”
and “868 MHz reception”).

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.

WHEN MORE THAN ONE TRA NSMITTER IS USED

1. User shall remove all the batteries from the thermo-hygro-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 thermo-hygro-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 this information is not displayed on the LCD after 60 seconds,
remove the batteries from both units and wait for at least 60
seconds before reinserting them.

4. The outdoor temperature and humidity data from the first transmitter
(channel 1) should then be displayed on the thermo-hygro-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 in the second transmitter as soon as the outdoor
temperature and humidity readings from the first transmitter are
displayed on the thermo-hygro-station.

Note :

User shall insert the batteries into the second transmitter
within 45 seconds after the thermo-hygro-station displays the
information of the first transmitter.

6. The outdoor temperature and humidity from the second transmitter
and the "channel 2" icon should then be displayed on the thermo-

27

hygro-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.

7. Insert the batteries in the third transmitter as soon as the "channel
2" icon and outdoor data are displayed on the thermo-hygro-station.
Then within 2 minutes, the channel 3 outdoor data from the third
transmitter will be displayed and the channel icon will shift back to
"1" once the third transmitter is successfully received. If this is not
happen, user shall restart the setting up from step 1.

User shall insert the batteries into the third transmitter within

Note :

45 seconds after the thermo-hygro-station displays the information
of the first transmitter or immediately after reception of the second
transmitter is finished.

8. In order to ensure sufficient 868 MHz transmission however, the
distance between the thermo-hygro-station and the transmitter
should not be more than 100 meters (see notes on “Positioning”
and “868 MHz reception”).

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.

DCF 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 radio-controlled thermo-hygro-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.

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 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.
