A random program override switching can be interrupted at any time.
After cancellation of the random program override switching, the time switch car-
ries out a program review. This causes the time switch to inspect the stored pro-
gram and then take up the correct switching status.
Example:
Stop random program Channel
C2
Note:
The symbol
r
turns OFF

6.5 Stop Random Program / override switching

A random program can be switched ON manually in the automatic program
(Auto) at any time. It remains active until switched OFF (chapter 6.5).
Note:
If the random program is active in a channel, the symbol
r
(random)
appears beside the channel.
Example:
Switch ON random program in Channel
