My ATO and 2 water storage bins are fed from my RODI unit and controlled by float switches and solenoid valves. Programming for each of these items is as follows.
ATO
Fallback OFF
Set OFF
If Output AWC_VO = ON Then OFF
If SmpFil CLOSED Then ON
If SmpHI OPEN Then OFF
When On > 015:00 Then OFF
If T_Salt < 33.0 Then OFF
NSW Storage
Fallback OFF
If NSW_Lo CLOSED Then ON
If NSW_HI OPEN Then OFF
AWC Storage
Fallback OFF
If AWC_LO CLOSED Then ON
If AWC_HI OPEN Then OFF
The ATO is fed directly from the RODI unit and does not use a pump. Water pressure feeds the sump and is controlled by floats in the sump and turned on and off by solenoid.
My issue is when refilling either the NSW or AWC storage tanks that if the ATO calls for water the RODI system won't fill it until the storage tank is full. In other words, you can only fill one item at a time. The time to off line of code in the AWC is used to prevent the AWC from overfilling the sump; maybe this is too redundant but I like the safeguard. If I add code that says if AWC is on then off to the Storage tank programming the filling process will be interrupted but won't return to filling after the ATO is complete.
So I would like to add programming that would allow the storage tanks to stop filling when the AWC asks for water, then resume filling when the ATO is off. Is this possible and if so what is required to make this work?
Thanks for your help.
