Running a dosing pump for 30 seconds in apex?

[lbacha]

This is not correct.

I read it wrong it actually goes back to Jan 1996 and starts the osc from there

Love you, was looking all over for this!

Bringing back this thread from the dead (hey that rhymes!) as I’m using an old apex aqua controller for a coral QT.

If I want my dosing pump to run 5 sec at midnight, but only 3 days per week, how would I code that?

I understand using OSC to run five seconds at midnight everyday, but how do I limit the days?

Thanks!
