Hello everyone, novice Apex user looking for help with an issue.
Lost power for 6hrs in a storm last night. Generator ran during that time. Had a hiccup with the Tunze ATO though, when it got power back, it dumped the entire contents of my top off water into the sump and nearly flooded the display. Good thing I was there.
Does make me feel uneasy about power outage's then fast power restore when/if I am not home...........here is the story as I can piece it together.
My sump can handle the water from the display no problem.
I do not have these problems when cutting the return pump to do water changes / maintenance.
The problem was the ATO ran right away and too long under false pretenses after power restore.
The topoff is the Tunze top of the line with the infrared eye.
The water level in the sump was fine in the end, it was the display that was on the brink of overflowing.
I guess that's a consequence of a choked drain line and needing to wait for things to equalize after power outage.
The way I am trying to think of how the scenario went is:
1.) Power back on and the sump level went low due to the return pump kicking on.
2.) ATO kicks on and stays on due to low sump level.
3.) By the time the choked drain line began flowing correctly to restore the correct sump water level there was now too much water in the system.
4.) When settled, the open return kept the sump level correct.
5.) When settled, the choked drain..................with now all the excess ATO water...............made my display level overflow.
Sound right? I was overseeing the generator operation and getting it stable and covered while this was all taking place.
The resolution for this would be to build something into the APEX by which the ATO will not turn back on after power restore until at least 15 minutes after.
Here is my ATO program that ensures when the return pump is turned off or my maintenance virtual outlet is turned off the ATO will not kick on for 7 minutes.
This does not help in a power outage/restore because it would require me to gain access to my network, get on my phone or browser, turn the outlet maintenance on.........or the return pump outlet off manually.......and by that time the damage would already be done.
Here is my current ATO profile set to auto:
Set ON
Fallback ON
If Outlet Maint = ON Then OFF
If Outlet Maint = OFF Then ON
Defer 007:00 Then ON
If Outlet ReturnPump = OFF Then OFF
To this I would need to add some kinda "If power lost, defer this outlets normal operation until X" I think. I am not aware of the proper syntax or placement of such a statement. Please help so I don't ruin my floors :wavehand:
