As you know, I've been emailing back and forth with Wayne at Fleck regarding BLFC, etc. In my last email, I asked for his overall programming recommendations. Thought I'd share his reply - not for any particular reason, I guess for the group's discussion (his replys in italics):
System: 7000SXT 64K 2 cuft resin.
64K is at max salt dosage, not efficient. 64K is a 12" tank
salting at 18lbs per cuft. You have 2 cuft.
Use: 300 gals per day X 14gpg hardness = 4200 grains per day
Would like to regen every 8 days (Day Override)...4200 grains X 8 days = 33600 to be regen'd.
I would normally add 1 day for reserve (33600 + 4200 = 37800)
Assuming: 3 lbs salt regenerates 10000,
General thought that 3,333 grains per lb of salt.
this would require 11.5 lbs of salt (which is good)
Assuming: 1 gal water dissolves 3 lbs salt, and 8 mins per gal = 31 min BF
I would use a grain setting of 48,000 which is at 8lbs per cuft salting.
16lbs total. That needs 5.3 gallons of water in the brine tank.
My questions (finally):
1. If I use Reserve Selection of Variable Reserve (cr)...does that change my programming?
2. (ref my previous email) Is there any advantage to me to change my Control Type from Meter Delayed (fd) to Variable Fill (fdPb)??
3. Overall, if possible, can you recommend my settings for:
Control Type (CT) Fd
Reserve Selection (RS) I would use rc fixed reserve.
BF? 42 min 43min x .125gpm = 5.3 gallons
Program capacity at 48,000 grains.
Set rc to 300gallons
