4.4.2 How to clear a switching point
The numeric of a switching point is not fixed. If a switching point is deleted the numbers of the
remaining points will be assigned again, thus there is no chance of holes in the time program.
4.4.3 How to clear a whole time program
4.4.4 How to protect the time program
The function of the time program is based on the clock and calendar data.
The clock is supplied by a battery (1,5 V AA). A warning signal
shows, when the battery has
to be changed. The exact time and date won’t get lost while the battery is getting changed (for 2
minutes).
In case of not using the control-unit for a long time, including a complete discharge of the
batteries, you will have to check, if time and date are still correct after a battery change, to avoid
problems.
The saved switching points are independent of the battery charge, because the program is
saved on a secured EEPRON-memory card. Thus time programs cannot get lost as a
consequence of a battery change or in the case of any other mistake.
If you want to clear a switching
point, you have to push and
hold the
CLR button. The
symbol CLR will blink in the
display, so that you are warned
you are going to clear a
switching point. If the
CLR
button is released immediately
the cancellation will be stopped.
If the cancellation is completed
horizontal lines are visible.
Afterwards the new number of
free switching points is
displayed.
To clear a whole time program
you have to push and hold the
CLR button while the number of
free spaces are shown in the
display
(FrEE) .
The symbol CLR will start to
blink, to warn you. If the button
is released immediately the
cancellation of the program will
be stopped.
The cancellation is completed, if
horizontal lines become visible.
That is followed by the new
number of free spaces (19).
