5. Elements and buttons

5.1 Base station (Receiver)

PRIMAVERA - Wireless weather station

• If the clock cannot detect the DCF-signal (for example due to disturbances, transmit- ting distance, etc.), the time can be set manually. The DCF symbol disappears and the clock will then work as a normal quartz clock. (see: Manual settings).

6.3.1 Note for radio-controlled time DCF

The time base for the radio-controlled time is 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 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 clock receives this signal and converts it to show the precise time. Changeover from summer time or winter time is automatic. In Daylight Saving Time “DST” is shown on the LCD. The quality of the reception depends mainly on the geographic location. Normally there should be no reception problems with- in a 1,500 km radius around Frankfurt. Please take note of the following:

• The recommended distance to any interfering sources like computer monitors or TV sets is at least 1.5 - 2 meters.

• Inside ferro-concrete rooms (basements, superstructures), the received signal is natu- rally weakened. In extreme cases, please place the unit close to a window to improve the reception.

• During night-time, the atmospheric interference is usually less severe and reception is possible in most cases. A single daily reception is adequate to keep the accuracy devi- ation under 1 second.

6.4 Inserting the batteries in the base station

• The batteries will operate as a backup power source in case of power failure.

• For a permanent backlight use the supplied power adapter.

• Open the battery compartment at the back of the base station.

• Insert two new batteries 1,5 V AAA into the battery compartment. Make sure the polar- ity is correct.

• Close the battery compartment again.

• During the operation, all successful settings will be confirmed by a brief beep tone.

• The device will automatically quit the setting mode if no button is pressed for a long period of time.

• Press and hold the +/RCC or -/°C/°F button in the setting mode for fast running.

• Press and hold the SET button in normal mode for two seconds, to enter the setting mode.

• The continuous backlight will turn on automatically.

• TIME ZONE and 0 (default) will be flashing on the display.

• Close the battery compartment again.

6.2.1 Reception of the outdoor values

• The outdoor values of the outdoor transmitter will be transmitted to the base station. The displays of the outdoor values are flashing “--.-”.

• On the display of the base station appear the channel number, the outdoor humidity and the outdoor temperature in °C (default).

• If the reception of the outdoor values fails within three minutes, “- -” appears on the display. Check the power adapter and the batteries of the transmitter and try it again. Check if there is any source of interference.

• You can also start the outdoor transmitter search manually later on (for example when the outdoor transmitter is lost or the batteries are changed).

• Hold the CH button on the base station for three seconds.

• “---” appears on the display.

• Press the TX button in the battery compartment of the outdoor transmitter.

• The device will alert you with a beep and the base station receives the values from the outdoor transmitter.

• After successful installation close the battery compartment of the outdoor transmitter carefully.

6.3 Reception of the DCF frequency signal

• After the reception of the outdoor values, the device will now scan the DCF frequency signal and the DCF symbol will be flashing on the display.

• To avoid interference, the backlight (and the USB output) turns off during the reception of the radio controlled clock.

• When the time code is received successfully after 2-12 minutes, the radio-controlled time and the DCF symbol are displayed steadily in the display. The backlight is activat- ed permanently.

• You can start the initialization manually.

• Press and hold the +/RCC button.

• The DCF symbol will be flashing.

• The continuous backlight will turn off automatically.

• Interrupt the reception by pressing the +/RCC button again for three seconds. The DCF symbol disappears.

• The DCF reception always takes place hourly between 2:00 and 5:00 o'clock in the morning. If the reception is not successfully received until 5:00 o'clock, the next receive operation is again at 2:00 o'clock in the morning. There are three different reception symbols: flashing - reception is active stays - reception is very good no symbol - no reception / time is manually set TFA_No. 35.1136_Anleitung_04_21 27.04.2021 10:21 Uhr Seite 112322 PRIMAVERA - Wireless weather station

9. Weather forecast symbols (Fig. 4)

• The weather station has five different weather symbols (sunny, slightly cloudy, cloudy, rainy and stormy).

• The weather forecast relates to a range of 12 hours and indicates only a general weath- er trend. The accuracy is about 70 %.

• For example, if the current weather is cloudy and the rain symbol is displayed, it does not mean the product is faulty because it is not raining. It simply means that the air pressure has dropped and the weather is expected to get worse but not necessarily rainy. The accuracy is about 70 to 75%.

• The sun symbol also appears at night if there is a starry night. Note: Please note that the forecast symbol will become more defined in the course of opera- tion. The forecast symbol is active right from the start, however, the reliability of the forecasts increases with the amount of data collected. The sensor must adapt initially to the reference level at the site.

• The maximum and minimum values are automatically reset at midnight.

• Press the MAX/MIN button in normal mode.

• MAX appears on the display.

• You can now get the highest values for the indoor and outdoor temperature and humidity since the last reset.

• Press the MAX/MIN button again.

• MIN appears on the display.

• You can now get the lowest values for the indoor and outdoor temperature and humi- dity since the last reset.

• Press the MAX/MIN button once more, to go back to the present values display.

• The device will automatically quit the MAX/MIN mode if no button is pressed.

• Press and hold the MAX/MIN button for two seconds while the maximum or minimum values are displayed to clear the recorded readings.

PRIMAVERA - Wireless weather station

• With the hanging hole at the back of the outdoor transmitter, the transmitter can be wall mounted at the respective location. Choose a shady and dry position for the out- door transmitter. (Direct sunshine falsifies the measurement and continuous humidity strains the electronic components needlessly).

• Check the transmission of the signal from the outdoor transmitter to the base station (transmission range of up to 60 m free field). Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened.

• If necessary choose another position for the outdoor transmitter and/or receiver.

13. Care and maintenance

• Clean the devices with a soft damp cloth. Do not use solvents or scouring agents.

• Remove the batteries and pull out the power adapter of the socket, if you do not use the products for a long period of time.

• Store the devices in a dry place.

13.1 Battery replacement

• Change the batteries of the outdoor transmitter, when the battery symbol appears on the display of the outdoor values.

• Change the batteries of the base station, when the battery symbol appears on the dis- play of the indoor values.

• Please note: When the batteries are changed, the contact between outdoor transmitter and base station must be restored – so always insert new batteries into both devices or start a manual transmitter search.
