After you pair the 2, with the slave on orange color (find it by pressing the mode button on the slave unit), turn the slave dial down to the speed you want - just like that
I have 3 running on my system and all is good
One master, one slave, and one on the back (back is only paired/controllable in Eco-Smart mode)
All are controllable independantly speed-wise, if you have the slave on the correct setting
White is slave synch
Orange is slave anti-synch
Turquoise is for a 3rd back pump in Eco-Smart mode
It's also a good idea (before you go through all the setup crap) to upgrade the pair of pumps to whatever firmware each has
Go through the steps in the manual or user guide so they are up to date
The newest firmware from any pump will upgrade them all
Good luck
