Hello

I think Weekly Timer

 Thanks both.

I will start with a weekly timer and see if that works best for me.

Or you use F4 as a release on/off.

 Yes, excactly what i did . Thanks again.

Hi,

instead of the weekly timer the astronomical clock is an option.  with LOGO! 8

With this LOGO! function calculates sunrise and sunset. A delay (+/- 59 minutes) is also possible. If you use this function your pump only runs if you press F4 and it is dark.

But the LOGO! time&date needs to be synchroniced. Best is to synchronice via NTP with your router.

Hope this helps
