Control valve settings
I'm trying to understand how to determine/confirm the settings for my Fleck 5600SE valve. I think I've found enough info from various sources, including Purolite (I'm using their SST-60 resin) to figure out the brine refill (planning to use 5 minutes = 6.75 lbs). But I've been unable to find info on determining the other three settings (backwash; brine/slow rinse; fast rinse).
Can someone point me to resources that will explain (preferred, for your sake
), or write up an explanation?
1.25 cu ft SST-60 resin
10 x 44 resin tank
city water, clean clear appearance
no iron
daily usage avg 250 gals
hardness 8 - 10 gpg (I use 10 for calcs)
Thanks in advance.....

System wouldn't let me edit to add info, so I'm doing it indirectly via a reply........

BLFC = .5 GPM
DLFC = 2.4 GPM

Cycle times
Every water softener "expert" has strong opinions on cycle times, this can a very contentious subject.
The key to regeneration cycle times is allowing enough contact time during brine/rinse and backwashing for adequate bed expansion during backwash. Rapid rinse is designed to settle the bed and flow softened water through the bottom of the bed to prepare it for service.
SST-60 can regenerate with less salt than traditional gel resins, so you can squeeze some good efficiency out of it.
Give me a little more data, & I'll thow my hat in the ring on recommended settings:-
Is this an upflow or downflow valve ?
What is the cycle sequence of operation on this particular SE ?

I'll use those, and a ten day override.
Can you give me some idea how you arrive at the first three settings?
And, if you will, a couple more questions....
What does the DLFC control? Just the backwash?
What does the abbreviation BV mean in the table at the top of page 3 of this document from Purolite?

BV = Bed Volumes
Figures are derived from the BV rinse & contact time requirements as well as experience with this particular media/control valve combination.
DLFC controls the maximum flow down the drain, so it will affect both backwash and rapid rinse
