Example of timer use
The following example shows how a timer is used and
connected to different parameters. The example uses the same
settings as application macro 9 Internal timer with constant
speeds. In this example, the timer will be set to function every
weekday from 6 AM to 8 AM and 4 PM to 6 PM. On weekends,
the timer is activated between 10 AM and 12 AM and 8 PM and

You can use the Timed Functions Assistant for easy configuring.
