Auto top off code help -

[Rwwilli]

I'm using the Neptune ATO to refill the auto top tank under the main display. I did not want to just refill from the drum in the fish room due to the size of that container.

I am using a liquid sensor(ATOtop) on the top of the Top off tank. 13 inches is above the ATOhi sensor on the ATK and I want to refill the ATO tank when it reaches 2 inches of water. I am using the ATK optical sensors to first shut down the pump but using the liquid sensors as back up. Also using a leak sensor on top of the ATO tank and also on the floor of the sump. (Liqlft and Liqrht are the sensors on the floor of the sump)

Problem - Once the liquid sensor reads over 2 inches of water the ApexATO shuts off, because the liquid sensor reads over 2 inches.

Is there a way to program the Neptune to read the liquid sensor but then to ignore it until the ATOhi reads full?
Should I time how low it takes for the tank to fill and set the timer for that time then keep the programming reading the sensors to stop from overfilling?

Thanks in advance- Code below -

Fallback OFF
Set OFF
If LkATOp CLOSED Then OFF
If Liqrht CLOSED Then OFF
If LiqLft CLOSED Then OFF
If ATOtop > 13.0 Then OFF
If ATOtop < 2.0 Then ON
If Atohi CLOSED Then OFF
If LkATOp CLOSED Then OFF
When On > 015:00 Then OFF
Defer 000:10 Then ON
Min Time 005:00 Then OFF

Try this:

Fallback OFF
Set OFF
If LkATOp CLOSED Then OFF
If Liqrht CLOSED Then OFF
If LiqLft CLOSED Then OFF
If ATOtop > 13.0 Then OFF
If Atohi CLOSED Then OFF
If LkATOp CLOSED Then OFF
If ATOtop < 2.0 Then ON
When On > 015:00 Then OFF
Defer 000:10 Then ON
Min Time 005:00 Then OFF

I think it needs to be the last "true" statement.

Also the level sensor works for this but it wouldn't be my first choice. They do lag a bit to send readings. For this I use optical sensors.

I am using the optical sensors on the ATK system. There are two. One high and one low, otherwise yes I would have had to place at least one optical sensor in the top off tank.

For now I timed how long it too to fill the tank when it was at two inches, subtracted 3 minutes. I will see how that works and I appreciate your thoughts on the code.
