ᐅ Issues with the Suevia Astro Log. What exactly do C1 and C2 refer to?

Greetings!

I’m starting to get really frustrated. We bought a house where the shutters on the ground floor are controlled electrically. The control runs through a Suevia Astro Log. Unfortunately, I can’t make much sense of the user manual.

Does anyone know this timer? What exactly are C1 and C2?

I just want to set the shutters to go up at sunrise and go down at sunset, but still be operable manually at any time.

Unfortunately, it always seems to fail because of the C1/C2 settings. So far, I haven’t found any logic in the tests.

Can someone help me? I really don’t want to buy a new timer just because of my own lack of knowledge.

C1 and C2 are the relay outputs... one normally closed and one normally open.

As I see it, the timer must be switched to manual mode each time to operate the roller shutters manually.

Otherwise, they probably only run in automatic mode and cannot be operated manually.

Thank you for your response. I will keep trying my luck.
