SETTING UP:
1. First, insert the batteries into 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 and a short signal tone will sound. Then the indoor temperature, the time as 0:00 and the date as
1.1. will be displayed. If the indoor temperature is not displayed after a few seconds, remove the
batteries and wait for at least 10 seconds before reinserting them. Once the indoor data is displayed
proceed to step 2.
2. Within 3 minutes of activating the Temperature Station, place the batteries into the Temperature
Transmitter (see “How to install and replace batteries in the Temperature Transmitter” below).
3. After inserting the batteries into the transmitter, the Temperature Station will start receiving transmissions
from the transmitter. The outdoor temperature should then be displayed on the Temperature Station. If
this does not happen within 15 minutes, the batteries will need to be removed from both units and reset
from step 1.
4. The Temperature Station can take up to 3 remote transmitters. If you have purchased additional
transmitters, follow step 2 for all extra transmitters. However, ensure that you leave 10 seconds in
between the reception of the last transmitter and the set-up of the following transmitter. The Temperature
Station will number the transmitters in the order of set-up, i.e. the first transmitter will have the
temperature displayed with the number 1 against it and so on.
5. When all the transmitters are set up, there is a testing period, during which the display switches quickly
between all the received transmitters at random, according to which random transmission it receives.
27
6. Pressing any key will stop this process and the display will show the temperature for the first transmitter.
The process also stops automatically if no keys are pressed for a few minutes.
7. Once the remote temperature has been received and is displayed on the Temperature Station, the DCF77 time code reception is automatically started. This takes typically between 3-5 minutes in good
conditions. This time period is an excellent opportunity to locate the transmitter(s) in suitable location(s)
outdoors. In order to ensure sufficient 433 MHz transmission however, this should under good conditions
be no more than 25 meters from where the Temperature Station will be finally positioned (see notes on
“Positioning” and “433 MHz Reception check”).
8. If after 10 minutes the DCF time has not been received, use the SET key to manually enter a time
initially. The clock will automatically attempt each hour to receive the DCF time. When this is successful,
the received time will override the manually set time. The date is also updated with the received time
(Please refer also to notes on “Radio controlled time” and “Manual time setting”).
HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE STATION
The Temperature Station uses 2 x AA, IEC LR6, 1.5V batteries. When batteries
need to be replaced, the battery symbol will appear on the LCD. To install and
replace the batteries, please follow the steps below:
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 polarity (see marking).
3.
Replace compartment cover.
28
HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The transmitter uses 2 x AAA, IEC LR3, 1.5V batteries. To install and replace
the batteries, please follow the steps below:
1.
2.
3.
Remove the cover.
Insert the batteries, observing the correct polarity (see marking).
Replace the battery cover on the unit.
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 3 minutes of power being supplied to it.
BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of
these units.
Please participate in the preservation of the environment. Return used
batteries to an authorized depot.

LCD 1 RADIO CONTROLLED TIME:
Minutes (flashing)
Hour (flashing)
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 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. 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:
33
•
•
•
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 - the reception is possible in most
cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.
MANUAL TIME SETTING:
In case the Temperature Station is not able to detect the DCF-signal (disturbances, transmitting distance,
etc.), the time can be manually set. The clock will then work as a normal Quartz clock:
1.
Press and hold down the SET key for around 2 seconds until the time display flashes.
2.
Use the IN key to set the hours and the OUT key to set the minutes. Pressing these keys
continuously moves the hours consecutively by 1 and the minutes consecutively by 5.
3.
Either press the SET key once more to enter the set mode for the time zone and date section or do
not touch any buttons for around 30 seconds to confirm the set time.
Note:
The unit will still try to receive the signal every hour despite it being manually set. When it does receive the
signal, it will change the manually set time into the received time. During reception attempts the DCF tower
34
icon will flash. If reception has been unsuccessful, then the DCF tower icon will not appear but reception will
still be attempted the following hour.
TIME ZONE SETTING:

TEMPERATURE TRANSMITTER:
The temperature is measured and transmitted to the Temperature Station approximately every 60 seconds.
The range of the Temperature Transmitter may be affected by the temperature. At cold temperatures the
transmitting distance may be decreased. Please bear this in mind when positioning the transmitter. Also the
batteries may be reduced in power.
39
433MHz RECEPTION CHECK
The Temperature station will receive the temperature data within 15 minutes. If the temperature data is not
being received 15 minutes after setting up (the display shows “- - -”), then 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
(433MHz) may prevent correct signal transmission and reception.
4. Neighbours using electrical devices operating on the 433MHz signal frequency can also cause
interference.
Note:
When the 433MHz signal is received correctly, do not re-open the battery cover 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 around 25 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).
40
POSITIONING THE TEMPERATURE STATION:
The Temperature station comes attached with a removable table stand, which provides the
option of table standing or wall mounting the unit. Before wall mounting, please check that the
outdoor temperature(s) can be received from the desired location(s). To wall mount:
1. Fix a screw (not supplied) into the desired wall, leaving the head extended out the by
about 5mm.
2. Remove the stand from the Temperature station by pulling it away from the base and
hang the station onto the screw. Remember to ensure that it locks into place before
releasing.
POSITIONING THE OUTDOOR TEMPERATURE TRANSMITTER
The Temperature Transmitter is supplied with a holder that may be attached to a wall
with the three screws supplied. To attach to the wall, please follow the steps below:
1.
Mark the wall using a pen through the holes in the holder to obtain the exact
drilling position.
2.
Drill holes in the wall at the points marked.
3.
Screw holder onto wall.
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
41
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
433 MHz signal from the Temperature Transmitter at the positions that you wish to situate them. The
Temperature Transmitter simply clicks in or out of the holder. When inserting or removing the Temperature
Transmitter to or from the wall holder please hold both units securely.
CARE AND MAINTENANCE:
•
•
•
•
•
•
Extreme temperatures, vibration and shock should be avoided as these may cause damage to the units
and give inaccurate forecasts and readings.
When cleaning the displays and casings, use a soft damp cloth only. Do not use solvents or scouring
agents as they may mark the LCD and casing.
Do not submerge the units in water.
Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new
batteries of the recommended type.
Do not make any repair attempts to the units. Return them to their original point of purchase for repair by
a qualified engineer. Opening and tampering with the units may invalidate their guarantee.
Do not expose the units to extreme and sudden temperature changes, as this may lead to rapid changes
in forecasts and readings and thereby reduce their accuracy.
