15. DCF reception
The DCF signal is a signal broadcast from a
transmitter in Mainflingen (near Frankfurt am Main).
It has a range of up to 1500 km, increasing to
2000 km in ideal reception conditions.
Among other things, the DCF signal includes the
precise time (theoretical deviation of 1 second in a
million years!) and the date.
Of course, this eliminates the tedious manual
setting of summer and winter time on the weather
station, since the time change occurs automatically.
Searching for the DCF signal and its evaluation
will take a few minutes. Do not move the weather
station during this time and do not push any buttons.
A single successful reception per day will keep the deviation of the quartz clock in the weather
station below a second.
The outdoor sensor receives the DCF time signal and sends it to the weather station.
The reception symbol is displayed above the seconds. The symbol flashes during
reception.
The sensor automatically searches for the signal daily at 02:00 and 17:00 o’clock.
16. Manually setting the time and the date
• In normal display mode, press and hold the TIME SET button for 2 seconds. The first
parameter flashes.
• Press the C or MEM/- button to change the value. Press and hold the button for
fast setting.
• Press the TIME SET button to confirm the setting and to go to the next parameter.
• If you don’t press any button for 60 seconds, the last set value is accepted and the weather
station switches to normal display mode.
