Please help me alter current code to run 2 Tunze pump at alternating mode

Roberto wrote this for me to run 1 Tunze pump at 75% from 2pm to 12am then from 12am to 2pm at 25%
////// Place your custom code below here
if (hour()>14)
{
ReefAngel.PWM.SetDaylight (75);
ReefAngel.PWM.SetActinic (75);
}
else
{
ReefAngel.PWM.SetDaylight (25);
ReefAngel.PWM.SetActinic (25);
}

////// Place your custom code above here


New settings:

2 Tunze pumps to run at 75% from 12pm -12am at 75% alternating every 60 seconds then from 12am-12pm at 25%

Thank you

Try this:

Thank you for the fast respond - I'll give this a try.

Hey Roberto can you please change the alternate time to every 2 hours instead of every 60 seconds.

Thanks - JaY

Come on man... you can do it

Is this correct?

////// Place your custom code below here
if (hour()>14)
{
ReefAngel.PWM.SetDaylight (now()%(10)<2?25:75);
ReefAngel.PWM.SetActinic (now()%(10)<2?75:25);
}
else
{
ReefAngel.PWM.SetDaylight (25);
ReefAngel.PWM.SetActinic (25);
}

////// Place your custom code above here

I think you need to % 14400 with the remainder < 7200 (so modulus the day by 4 hours (14400) and remainder less than 2 hours (7200)

Previously it was modulus 2 minutes (120) with the remainder being less than 1 minutes (60)

The code uses seconds and not hours.
120 seconds = total cycle
60 seconds = time to switch from 1st half to 2nd half of cycle
You can even make asymmetric waves... If you make total cycle 120 and switch 20, you will have 1st cycle duration at 20seconds and 2nd half at 100s.

Okay how about this?

////// Place your custom code below here
if (hour()>14)
{
ReefAngel.PWM.SetDaylight (now()%(4*60*60)<(2*60*60)?25:75);
ReefAngel.PWM.SetActinic (now()%(4*60*60)<(2*60*60)?75:25);
}
else
{
ReefAngel.PWM.SetDaylight (25);
ReefAngel.PWM.SetActinic (25);
}

////// Place your custom code above here

There you go
Not too difficult, right?
