I use Profilux controller to control all pumps using ecosmart options. If i set up NTD mode, then how you have it set as one master and others are slaves?
In my case one MP60 one right side, let say will be master aacnd oposite slave? Same with MP40s on the back?
Why do you have them run only 20% constant at night? seems like 20% is really low flow, specially in your large system?
I blast the snot out of my tank for 12 hours a day, so I give it a break at night. I could always up the flow I guess, but not really needed, IMO.
If you are programming via your apex, then you would not program a master/slave type like if you were programming the pump via the driver mode/set/power buttons.
In ESL, for example, if I want to program NTM from 9am-3pm, and I have one pump on the left glass, one on the right glass, and two on the back. I program the left or right side pump in actual NTM, the opposite pump anti sync, and the back glass pumps in "Ecosmart Back" mode, all for that 9am-3pm period.
Another NTM example: 2 pumps left side, 2 pumps right side, 2 pumps back. Program one left side pump in NTM, the other left side pump in Sync mode, the right side pumps in antisync mode, and the back pumps in "ecosmart back" mode.
Manual programming a master/slave setup via the driver buttons does the same thing, with the master pump showing the purple led on NTM, any slave pumps on the same side as the master showing white sync mode, any slave pumps opposite the master showing orange anti sync mode, and any slave back glass pumps showing turquoise ecosmart back mode.
You would just need to set up equivalent programming on the apex to do this.
