ATO high and low level..

[Daniel Malloy]

I'm just trying out the ATO using the control 2. For some reason it starts filling when the water trips the lower level and runs for like 5 seconds filling it all the way to the high level on the sensor. Which is odd and I'm hoping it's something I'm doing wrong?..

The ATO recipe only allows for one water sensor. If you want to use a second higher sensor as a backup, you need to create a "Generic" OUTPUT with 2 inputs. Make input 1 your low water sensor and set it to "active" when DRY. Set the high water sensor as your second input and set it to "active" when DRY. Then set the relationship to AND. This way, the OUTPUT will only activate when both your low and high water sensors are DRY. If your bottom water sensor gets stuck, the OUTPUT will stop as soon as the higher water sensor becomes wet.

I'm only using the one water level sensor. There are 2 optical sensors on one SINGLE sensor. Mine was starting to fill at the low one.. then would dump a bunch of RODI (ran for around 5-6 seconds) and it would fill up to the High one. My tank is only 50 gallon with a 29 sump so that is way too much H2o at once. I have an XP Aqua Duetto which has the same "dual" optic sensors and it Always fills to the lower one. I'm pretty sure they all do and the upper one is maybe a safety shut off. I dunno.

The Hydros sensor is just a single sensor. It is either wet or dry. If I get you right it runs for 5 seconds and that is too much time. How do you have the output setup? Do you have a minimum on time set?

I appreciate you sending me a new water level sensor! I will try it and hopefully that is the issue and not something else. I'm just using the control 2 with a temperature probe (the magnet one) and the ATO pump and sensor. That's all except for the Wave Engine but it just runs my 2 ice cap pumps. I'm All about CoralVue's products.. for a few years now. Thanks again Carlos.. Ur the Man!

I tried fixing it that way but it kept going over my max on time, trying to make it to that top part/ sensor or whatever.

The output was drive port 2 and sense port 2. Yes I tried only 1 2 and 3 seconds but it kept filling it to the upper part of the sensor.

The reason I ask is if you set a minimum on time it will run that long regardless of the sensor once it starts. I have mine setup in the screenshot below. I have a minimum off time set for 30 minutes. What this does is once the output is off it stays off for 30 minutes regardless of the sensor. I have the maximum off time set for 6 hours. It it stays off for that long I will get an alert stating that. I have the minimum on time set for 2 minutes and 15 seconds. Once on it will stay on that long regardless of the sensor. I have the maximum on time set for 5 minutes if it stay on that long I will get an alert stating that. I have run past max on time set to off. So if the pump runs to the maximum on time it will turn off. I use a dosing pump for ATO so my times are a lot longer than what you would use. I have a 42 gallon tank with a sump that is close to 10 gallons so I have a small system also.

I had a max on time of 2 seconds and it went passed that and filled it to the top of the sensor anyway. Then it sent me an alert saying max on time had been exceeded. I just turned off advanced settings and it still did the same thing. Weird man, I dunno?..

If a 2 second on time overfills then my guess is you are going to need a pump with a lower flow rate or find a higher area for the ATO pump output such as the overflow on the tank.
