Ola Fernando.
I have been reviewing one of my old posts from last year: viewtopic.php?f=8&t=309
Regarding the automatic water change system
I wonder if you agree it is possible to perform like this:
pins:
A0 sump lower
A1 sump ato sensores / running level
A2 sump upper
**In condition where return pump is running 100% flow rate.**
The level in "sump return chamber" is in a stable position while running.
Running level determines fixed position of A2 ATO sensores (Nível em execução)
Here is logic..
1. Check A1 ATO sensores > If LOW turn on RO-water until A1 correct, else skip (running level, return pump ON) (fixed position of A1 ATO sensores)
2. Then, Switch OFF return pump. Wait (x minutes). (Water stops and Back-flow into sump, level in "sump return chamber" rises.)
- When back-flow complete, water is much higher in sump return chamber. (fixed position of A3 sump upper/superior)
3. "Bomba que tira água do sump./Sump empty pump (A7)" switch ON, until A2 sump lower trigger. (fixed position of A2 sump lower)
4. "Bomba que coloca água no sump./Fresh SW return to sump(A8)" switch ON, until A0 sump upper trigger (fixed position of A0 sump upper)
5. Return pump on
At stage 5. Water should return to same position as before return pump switched off..
Do you think this is achievable?
I am not asking for code here, but opinion of my issue, if you can understand, perhaps I will post a picture shortly with logic.
