Time overlaps

The time settings of a time switch overlap. The clock switches on at 16:00 on
Monday, whereas on Tuesday and Wednesday it switches on at 10:00. On
Monday to Wednesday the switching-off time is 22:00.

Response in the event of a power failure

The power is removed between 15:00 and 17:00. The relay drops out and
remains off, even after the power returns, since the first switching-off time was
at 16:00.

IMPORTANT

Switch-on and switch-off times are always based on the
channel which switches first.

IMPORTANT

When switched on, Pico GFX-70 always updates the
switching state on the basis of all the available switching
time settings.
