I'm trying to do something in System Builder for my house and I cant figure out something. I have a pump for a aeroponic garden system I built (its like hydroponics but not quite). I need the pump to run and cycle water every 7 minutes on and 7 minutes off. repeated, forever. Im trying to use a CLW-LDIMEX-2 2 as the controlled outlet for the pump. I tried doing a Scheduler, but cant figure out how to repeat the events in minutes to cycle on and off. I tried adding a timer and that's not working out either. Any ideas? An actual hydroponics timer that does this is called a "cycle timer" or "repeat timer". The 7 minutes on and off is a starting point, I may need to fluctuate the times to be 6 on, 4 off, or 5 on 7 off. Dependant on the time of season if its hotter in July, I may need the roots to stay wet longer, etc.

I do not use System Builder but in Simpl there is the Oscillator and Variable Oscillator.
Are these present in System Builder ?

Yes, easy to do in Simpl.  I'll look into SB...

So in SB, insert 2 Separate Timers.  Set the time perameter in the properties of each timer.
Feed the Timer Expired to initiate the other Timer.
Timer 1 will be your "On" and Timer 2 will be your "Rest".
Obviously initiate your action when Timer 1 goes high, stop your action when Timer 2 goes high.
Initiate Timer 1 or Timer 2 on System Start, or via button press (can pause or stop the cycle also with a button press).
Very Crude but try and see if it works.  Test lots.

Just create a module in simpl and bring it into system builder. Done.

If he's using SB, probably not familiar with SIMPL.
