Q: Why do the cloud symbols not change or only change very rarely?

That's completely normal! The cloud symbols on your TFA Horizon 35.1155.01 station do not represent the current weather, but a weather forecast for 12-24 hours based on atmospheric pressure trends. Here’s why they change infrequently: They are based on atmospheric pressure trends , not on real-time conditions They only change when the weather pattern evolves - and this evolution is often slow and gradual During stable weather conditions, the same symbol may be displayed for several hours or even days - this is normal and not a defect The station displays five different symbols: sunny, partly cloudy, cloudy, rainy, and very rainy. A snowflake appears if rain is expected and the outside temperature drops below 0°C. Your device is functioning correctly. The symbols represent a general trend, not a constant update of the current weather.

Question 1

How to change the display language on the TFA 60.2025.01 alarm clock?

Accepted Answer

The TFA 60.2025.01 alarm clock does not have a language change function on the device. The LED display only shows the time, temperature, and alarm symbols - no text.

Here’s what you can modify using the MODE, ALARM, SNZ/LIGHT, and UP/DOWN buttons:

Time format (12/24 hours)
Temperature unit (°C or °F)
Display brightness (2 levels)
Alarm time and duration of the ringing
Automatic brightness timer

The user manual itself is available in several languages (French, English, German, Spanish, Dutch, Italian), but this only pertains to the manual, not the device itself.

Question 2

What are the symbols of the seasons displayed by this weather station?

Accepted Answer

The TFA Season 35.1118.01 weather station features a display of the seasons on its color LCD screen. The device identifies and visually displays the four seasons (spring, summer, autumn, winter) through specific symbols.

However, the provided instruction manual does not specify exactly which icons or graphic symbols represent each individual season. To discover the precise visual details, you can:

Consult the display diagrams in the PDF of the manual (Figure 1) available above

The 23 elements of the LCD display include temperature, humidity, weather forecasts (with 6 symbols: sunny, partly cloudy, cloudy, rainy, stormy, and snow) and other information, including the display of the current season.

Question 3

Which button to press to activate the radio-controlled time on the TFA 60.2557.01?

Accepted Answer

To activate the radio-controlled time (RCC) on the TFA 60.2557.01, press the RCC button in normal mode.

You will see "RCC ON" displayed on the screen, and the DCF symbol will start blinking, indicating that the device is searching for the radio-controlled signal.

Synchronization occurs automatically once an hour between 1:00 AM, 2:00 AM, and 3:00 AM. Once the signal is found and synchronized (usually within 3 to 7 minutes), the DCF symbol remains steadily lit, confirming successful synchronization.

To deactivate the radio control, press RCC again - the display will then show "RCC OFF" and the clock will operate in standard quartz mode.

Question 4

Why do the cloud symbols not change or only change very rarely?

Accepted Answer

That's completely normal! The cloud symbols on your TFA Horizon 35.1155.01 station do not represent the current weather, but a weather forecast for 12-24 hours based on atmospheric pressure trends.

Here’s why they change infrequently:

They are based on atmospheric pressure trends, not on real-time conditions
They only change when the weather pattern evolves - and this evolution is often slow and gradual
During stable weather conditions, the same symbol may be displayed for several hours or even days - this is normal and not a defect

The station displays five different symbols: sunny, partly cloudy, cloudy, rainy, and very rainy. A snowflake appears if rain is expected and the outside temperature drops below 0°C.

Your device is functioning correctly. The symbols represent a general trend, not a constant update of the current weather.

Question 5

How to configure or change the alarm tone of the TFA 60.2528.02?

Accepted Answer

The alarm tones of the TFA 60.2528.02 are not customizable. This device has two independent alarms (SET 1 and SET 2), each with a different preset tone, but these sounds are fixed and cannot be changed.

However, you can:

Independently set the time for each alarm using the SET 1 and SET 2 buttons
Activate or deactivate each alarm separately with the AL 1 ON/OFF and AL 2 ON/OFF switches
Use the Snooze function (SNOOZE/LIGHT button) to postpone the alarm by 5 minutes

If you want an alternative sound, your only option is to switch between the two alarms, each of which has a distinct preset tone.

Question 6

Why does the DCF symbol not appear on the TFA 30.3060.01 thermometer?

Accepted Answer

The DCF symbol on the TFA 30.3060.01 may not display for several reasons. It is important to understand that the absence of the DCF symbol means that the thermometer has not received the time signal - which is not necessarily a malfunction.

Understanding the states of the DCF symbol

Flashing: the thermometer is in the process of receiving the time signal
Steady on: successful synchronization with the DCF-77 signal
Absent: no signal received or the clock is set manually

Common reasons for the absence of the DCF symbol

Blocked signal: Place the thermometer near a window. Thick walls, reinforced concrete, metal structures, or an underground location can block the DCF-77 signal from Mainflingen, Germany.
Electronic interference: Keep the device at least 1.5 to 2 meters away from computers, televisions, microwaves, cordless phones, and other electronic devices that may disrupt reception.
Limited automatic synchronization: The TFA 30.3060.01 automatically synchronizes its clock only between 1 AM and 5 AM. If you performed the reset outside of these hours, wait until the next morning to give the thermometer a chance to receive the signal.
Geographical location: If you are very far from Mainflingen (Germany) or in a mountainous area, reception may be impossible or very unstable.

Solutions to try

Place the thermometer near a window facing Germany (ideally a north or east-facing window)
Move away all disruptive electronic devices
Wait 5-8 minutes after a reset - synchronization takes time
Press the CH button to manually force the search for the DCF signal
Try different locations in your home or garden

If the DCF symbol still does not appear after these attempts, it simply means that your location does not have good reception of the DCF-77 signal. In this case, you can continue to use the thermometer normally by manually setting the time via the SET button (see the manual for setting steps). The device will work perfectly to display temperature and humidity.

Question 7

Why doesn't the DCF symbol blink when changing the battery?

Accepted Answer

It is normal for the DCF not to blink during a simple battery change. The DCF symbol only blinks during active search for a radio synchronization with the time signal (77.5 kHz from Mainflingen).

Expected behavior of the DCF:

Blinks: only when receiving the current DCF signal (generally between 1 AM and 5 AM)
Continuously lit: radio synchronization has succeeded
No symbol: no reception / clock in manual mode

After changing the battery, you must restore the contact between the transmitter and the base station by pressing the CH button for 3 seconds (see page 6 of the manual). The DCF symbol will only blink if the signal is received at the time of this action.

If you want to force a manual search for the DCF signal, hold the CH button for 3 seconds once the transmitter-receiver connection is restored. The DCF symbol will then blink upon receiving the time signal.

Tip: DCF reception works best between 1 AM and 5 AM when the signal is available. If you test during the day, the DCF symbol will not appear.

Question 8

How to disable the alarm function?

Accepted Answer

To disable the alarm function on your TFA 30.5033.02, follow these simple steps:

Press the MODE button in normal mode to access alarm mode
Press UP four times to completely disable the alarm and the hourly signal
The alarm symbols will disappear from the LCD screen, confirming that the function is disabled
Press MODE to return to normal mode

Selective options: If you prefer to disable only the alarm (without affecting the hourly signal), press UP once. To disable only the hourly signal, press UP twice.

Question 9

How to set a radio station as an alarm on the TFA Tune 60.2546 clock radio?

Question 10

How to set the day, month, and time on the TFA Life 35.1153.02 weather station?

Accepted Answer

To set the day, month, and time on your TFA Life 35.1153.02 weather station, press and hold the SET button in normal mode. The year display will start to blink: you can then adjust the year using the ▲ (plus) or ▼ (minus) button.

Press the SET button again to move to the next step. The adjustment order is fixed: first the month blinks, then the day, followed by the time format 24h or 12h (24 hours is the default setting), then the hours, and finally the minutes. At each step, use the ▲ or ▼ buttons to change the value.

Once you have set each parameter (year, month, day, time format, hours, minutes), confirm by pressing the SET button to move to the next parameter. To speed up the setting, you can hold down the ▲ or ▼ button during the adjustment: the device will then switch to fast scrolling, which is particularly useful for setting the year or minutes.

The station automatically exits the setting mode after 8 seconds of inactivity (if no button is pressed). You will then return to the normal display of time and date. If you made a mistake, you can start over by pressing and holding the SET button again.

Tip: if your weather station receives a radio signal for the time (radio-controlled function), make sure that manual setting does not conflict with automatic synchronization. Also, check that the batteries are in good condition to avoid losing the settings.
