I’m having an issue with the sync anti sync function. I am running 4 MP40s in gyre mode. The master is set to 80% (3900gph) One slave is set to sync with the master. That works fine. The other 2 pumps are set to anti sync but they are only slowing down 25% to 2900gph. According to the manual the pumps in anti sync should run opposite but inverse of the master with a minimum speed of 10% or 450gph. In my case they should slow down to 20% which would be roughly 780gph. That is not happening which makes creating the gyre effect impossible. All drivers are up to date with the latest firmware. I called ecotech support which was helpful but they were not able to diagnose the issue. I was asked to submit a bug report through mobius which I did. Does anyone else have this issue?
