Apex Ramping return pumps

[PFas52]

Can someone point me in the right direction. I have two coralbox DCA-9 return pumps powering my tank. I have set up the 0-10v variable speed to control them. The left runs constantly at 60% and the Right at 35%.

I would like them to both ramp down to say 5% when I turn on my feed mode A and then ramp back up to what they are currently set at when the feed mode ends. I created a virtual outlet but now I’m lost.

You will need to create two Ramp profiles for each pump, one to ramp down, and one to ramp up:

For Pump A:

Profile Name: RampDownA
Profile Type: Ramp
Ramp Time: 1 (in minutes)
Start Intensity: 60
End Intesity: 5

Profile Name: RampUpA
Profile Type: Ramp
Ramp Time: 1 (in minutes)
Start Intensity: 5
End Intesity: 60

For Pump B:

Profile Name: RampDownB
Profile Type: Ramp
Ramp Time: 1 (in minutes)
Start Intensity: 35
End Intesity: 5

Profile Name: RampUpB
Profile Type: Ramp
Ramp Time: 1 (in minutes)
Start Intensity: 5
End Intesity: 35

In the programming, use overlapping If Feed timers:

[PumpA]
Fallback ON
Set 60
If FeedA 001 Then RampUpA
If FeedA 000 Then RampDownA

[PumpB]
Fallback ON
Set 35
If FeedA 001 Then RampUpB
If FeedA 000 Then RampDownB

Because the Apex evaluates each line of code from top to bottom, and the last one that's True sets the output state, the overlapping Feed timers will allow the RampDown to run, and remain at the ending 5%, until the timer expires, then the If FeedA 001 timer will be the last True line and cause the RampUp profile to execute for the remaining minute.

Thank you so much!!!! So I created the four profiles (two for each pump) Am I putting the programming in the 0-10v outlet tiles and under the return pump outlets themselves?

Sorry I didn't see this reply until just now.

When you have a variable speed pump, all the programming should be placed on the 0-10v outputs since that's what actually controls the pump. There's no need to have the pump's power cord plugged into a controllable output or have any programming for it. It should be always on, then let the 0-10v control it.

Can I accomplish a ramp up and ramp down for a retuen pump with a virtual feed outlet? I can't figure out how to program the 1 minute delay to then ramp back up? A defer line?
