I am not as good with this one -- so I would check this and I might not be understanding what you are trying to do ---- maybe someone else can chime in on this one
so I am getting that/understand is
if float 1 is open then the booster on _ solenoid A is ON and then if float 2 is open then booster on solenoid B is on --
so then Sw1 = Float in RO holding tank
Sw2 - float in top-off container
OPEN = low water (needs filling)
so code(s) would be
1) booster pump (say plug one on your EB832 or EB8)
Fallback OFF
Set OFF
If Sw1 OPEN Then ON
If Sw2 OPEN Then ON
Defer 001:00 Then ON
When On > 030:00 Then OFF
(basically if either container needs water the pump runs)
(when on statement - cuts off power/booster - if RO/DI water runs to much - small safety feature for flood/leak protection)
2) Solenoid for RO Holding tank (plug 2 on your EB832 or EB8)
Fallback OFF
Set OFF
If Sw1 OPEN Then ON
(only responds to Float 1)
3) Solenoid for Top-Off Chamber Container (plug 3 on your EB832 or EB8
Fallback OFF
Set OFF
If Sw2 OPEN Then ON
(only responds to float 2)
