Help with ATO

[oralallen82]

Hello this is my situation I have a Tunze ATO that is plugged to Outlet1. Even though the ATO has a float switch and automatically turns off after 3 mins I want a third failsafe. I want to have the ATO be on during a every other day but only be on for 4 mins. Just incase the float switch fails and the ATO doesn't turn off. Here is what I have:

Fallback OFF
If DoW SMT-T-S Then ON
If Time 22:00 to 11:00 Then OFF
Defer 004:00 Then OFF

However the Defer is not functioning. The outlet remains on

Thanks for the Help

Because you need a "Set Off" statement to tell the outlet what to do if it's "normal" state when the conditions below the "Set Off" statement don't override it. That the simplest way I can think of saying it.

Try this:

Fallback OFF
Set Off
If DoW SMT-T-S Then ON
If Time 22:00 to 11:00 Then OFF
Defer 004:00 Then OFF

Fallback OFF
If DoW SMT-T-S Then ON
If Time 22:00 to 11:00 Then OFF
Defer 004:00 Then OFF

This program won't do anything close to what you describe wanting.

The If DoW and If Time lines together will result in the outlet being ON constantly from 11:01 to 22:00 on Sun, Mon, Tue, Thurs, and Sat. The Defer does not cause the outlet to turn off after 4 minutes; it merely delays the outlet from turning off for an additional 4 minutes after the If Time statement tries to turn the outlet OFF. So, the end result is that outlet will be ON constantly from 11:01 to 22:04 on Sun, Mon, Tue, Thurs, and Sat.

Plus, the lack of a Set OFF as Chad pointed out is an issue.

You cannot program things for every other day; the closet you can do is 3 days a week, or 4 days a week. I'll go with allowing the ATO to operate on 4 days a week.

Fallback OFF
Set OFF
If Time 12:00 to 12:03 Then ON
If DoW -M-W-F- Then OFF

With this new program, the If Time statement will try to turn the outlet on for 4 minutes each day at noon. But the If DoW won't allow that on M, W, & F, so the outlet will only turn on at noon on Sun, Tue, Thu, and Sat.

Adjust the If Time statements as desired.

@RussM and @iamchadster thanks for the help @RussM I'll try that and let you know how it works. I greatly appreciate the help.

I am glad to report this works exactly like I expected.

Thank you

No problem. I wasn't paying attention to the rest of the program, I skimmed it quickly and saw the missing "Set Off" and thought "aha!". Sorry Russ! You had to jump in and save the day again for my oversight.

I have a VO set up titled ATOLIMITER.. Works great! If my ATO is on for more than 7 seconds the VO will terminate the feed. I think I have a redundant programming with the fallback off and set off, but I am not sure.

I also have it so the ATO Limiter will alert me if activated which also tells me either the pump was stuck on for some reason and it had to turn it off, OR I am out of water and need to refill my ATO tub. On top of all this I have a back up float that says if the water reaches that float switch to turn off the pump.. I feel much better.

Set OFF
If Sw1 CLOSED Then ON
Defer 001:07 Then ON

ATO has this coding

Fallback OFF
Set OFF
If Sw1 CLOSED Then ON
If Sw2 OPEN Then OFF
Defer 001:00 Then ON
If Outlet ATOlimiter = ON Then OFF
