I perform ATO and refill of my new salt water (NSW) tank directly from my RODI unit controlled by solenoids. My programming is as follows:
ATO
Fallback OFF
Set OFF
If SmpFil CLOSED Then ON
If SmpHI OPEN Then OFF
When On > 008:00 Then OFF
If T_Salt < 33.0 Then OFF
NSW Refill
Fallback OFF
If NSW_Lo CLOSED Then ON
If NSW_HI OPEN Then OFF
If Output ATO_4_4 = ON Then OFF
I added the last line of code under NSW Refill because when I am refilling the NSW reservoir my RODI can't do the ATO and that refill at the same time. I want to have the Apex temporarily close the solenoid to the NSW refill and open the ATO solenoid to replace the evaporated water in the display. When complete, the ATO solenoid closes and the NSW solenoid opens to continue refilling the NSW Refill. When I tested this today the ATO opened and completed its task but the NSW solenoid did reopen. What am I doing wrong? Thanks.
