I travel a lot and sometimes leave my tank for a month or more. Last year I started running my ATO res with a direct full time connection to the RODI system and its worked flawlessly. I am considering eliminating my ATO res and adding a few failsafe measures too. Did some reading on this and discovered that filling my ATO res on tank demand can lead to TDS creep and or low resin efficiency so I want to setup my ATO res to replenish itself only on certain days of the week.
Does anyone have feedback on this programming? I need to tweak the on time limit and min wait but wanted to get some feedback on this as is.
As far as tank side safety I run two optical sensors and a manual float valve in my sump and I have yet to have a problem. My goal is to eliminate TDS creep and automate the RO res refill so it only happens twice a week and in a highly controlled manner. Eventually I may eliminate the res and use this kind of programming on the tank side but may have to live with low resin efficiency for that.
Fallback OFF
Set OFF
If RODI CLOSED Then ON
If RODI OPEN Then OFF
When On > 0015:00 Then OFF
Min Time 060:00 Then OFF
If DoW SM-WTF- Then OFF
