Before you start
Have the current local time, date and your own PIN ready. Turn NTP off before manual editing. 12:30 and 2026-11-06 are examples only; time and date are saved separately. Controller access codes →
If the controller asks for a PIN
Enter your PIN on the display and confirm with OK. Use an account authorised for controller settings. If already signed in, continue to the next menu screen. Controller access codes →
On the home screen, tap MENU in the upper right. If prompted, enter your own PIN and confirm with OK. Controller access codes →

Check the clock on the home screen
Return using the home icon and check the date and time in the top bar. NTP synchronization stays off until you enable it again.
Finish and verify
Check both date and time on the home screen. Each settings page has its own disk-icon save. Keep NTP off for manual operation so synchronization does not replace your settings.
Open MENU → right arrow → Settings → RTC clock. Enter your own PIN if prompted. Controller access codes →
Open NTP. Turn NTP synchronization off so only the green outline remains, then return with the left arrow.
Choose Time. Use +/− on the left for hours and on the right for minutes.
Tap the disk icon in the upper left to save the time.
Choose Date. Set year–month–day and tap the disk icon again.
Return with the home icon and check both values.
Time and date are saved separately. The left arrow or home icon does not save edits in the time or date editor. Hours: 00–23, minutes: 00–59, years: 2025–2099. Month lengths and leap years are taken into account.
Prepare a LAN or Wi-Fi client connection to the time server.
Open RTC clock → NTP. If synchronization is enabled, turn it off first.
Choose a correction from −5h to +5h. For Poland and Germany, the standard correction is +1h.
Set Summer time mode: solid green adds an hour; an outline adds no hour. This is a manual switch; this screen does not offer an automatic daylight-saving calendar.
After choosing the correction and summer mode, enable NTP synchronization.
Leave using the left arrow. The NTP settings are saved and a time update is requested. Check the date and time on the home screen.
After changing the correction, turn synchronization off and on again. A green square confirms only that the feature is enabled, not that the time server has replied. Access Point mode and a phone connection to the controller alone do not provide NTP.
