Hello. I'm not good with these APEX codes. Please help me figure out why I keep getting text alarms all night.

I setup the ATK and used the given codes provided by APEX. the unit is working, but It's sending chain alarms. the tank at that time shouldn't have any feed or anything going to change water level dramatically

Fallback OFF
Set OFF
If Swx8_1 OPEN Then ON
If Swx8_2 CLOSED Then OFF
When On > 005:00 Then OFF
Defer 000:10 Then ON
Defer 000:04 Then OFF
Min Time 060:00 Then OFF

The code seems fine, but it may be a bad optical sensor? I had to replace several sensors on mine that were constantly throwing alarms. I've since removed the ATK from my system and have gone back to a gravity fed system without issue. Personally, I fucking hate the ATK, I think it's one of the most poorly designed ATO systems out there. The fact that you can't change the sensor height and their high failure rate makes it a poor choice for an ATO system.
If you want to dig in deeper to apex programming, check out SuncrestReef on the other forum or Neptune's forum. He has a few tutorials that walk you through programming. But, in the long run, I would sell the unit and buy a Tunze 3155 and move on, or better yet, set up a simple gravity fed system and save yourself the headache, if you can? Sorry for the rant, but the ATK is an overpriced POS! Your code is fine, but I'm guessing the sensor(s) are going bad.

I forgot to mention that you should switch sensor positions and see if the alarm follows that sensor. It's usually a bad sensor that causes these alarms sometimes.
