ᐅ Timer for circulation pump at the heating system

Hello everyone,
We have a timer switch for the heating circulation pump, see the picture.
But no matter how I set it, the circulation never works as it should. I just don’t understand it!
There are three modes you can set: permanently on, permanently off, or according to the schedule (middle setting).
I set it so that, for example, it should circulate tomorrow between around 6 and 9:00 AM. But it doesn’t. Of course, I also set the current time correctly according to the small arrow. I’ve tried everything.
What am I doing wrong?
Our heating system also has an option to control the circulation, see the other photo.
According to the heating installer, this won’t work if the manual timer is activated.

It really never works as I set it—for example, at 6:30 AM, freezing cold water for 1 minute.

FRUSTRATION!
Do you have any idea what this could be? Thanks a lot

You just need to pull out or push in a few of the black "teeth" around the edge, depending on the situation... and then set the red selector switch to "Clock".

Possibly rotate it completely once more to ensure it switches for the first time.

I had ruled out user error 🤨 🙁
As far as I can tell, only the "teeth" between 7 pm and 8 pm are pressed in.

The clock in the photo is also not set to the timer mode. Therefore, I assume it is an "archive image."
At least, I trust no one would fail to check such basic details before asking for help online worldwide 😉

Which brings us back to the person with the empty (car) tank calling the workshop/AAA/...

Is it really correct that there is a standard analog timer on the pump and the time control is also managed through the heating system? In our case, the circulation pump is also time-controlled, and I only need to adjust the heating system for any changes, without touching a timer.
