Apex ato

[swearint]

... if the Allow is on and the switch is closed (I flipped my switch and statements to shut off on open at your advice) will it automatically run the full duration of the allow window?

Depends. While ATO_Allow is ON (OFF = FALSE), the float switch will provide normal control. As long as Switch1 is CLOSED, the ATO will run (assuming all other conditions are false). Once Switch1 is OPEN, the Set OFF will shut ATO OFF. So ATO_Allow creates a max runtime, but does not force ATO to run.

... if I understand the OSC correctly this statement will run for 3 mins, starting at 13:30, then off 27.5 mins and back on for 3 then off for 13.5 mins again, essentially giving me windows around the 15 and 45 min mark on each hour right?

Yes, except that it will turn OFF for 27 minutes rather than 27.5. It is synched from midnight, so it will turn on at 00:13:30 and off at 16:30. Then on again at 00:43:30, off at 00:46:30 and so on. You could use OSC 27:00/3:00/00:00 and get the same thing but a bit cleaner (00:27 :00 to 00:30:00, 00:57:00 to 1:00:00, etc.)

Aw thats great, I like that much better. I didnt realize that the Apex continually re evaluated the statements. I thought it only check when a state that was listed out changes. ie on off statements. Very interesting. Thanks for all your help swearint so far my ATO has been working like a champ.

 

[swearint]

That is correct. The Apex cycles repeatedly through the code, not sure of the exact speed, but overall the timing accuracy is about one second. The last true statement will determine the state of an outlet.

Great thread but I have one question. if i wanted the top of to come on after lights out and work till lights on, where would that line go, in the virtual outlet or the actual outlet?

Thanks

You question is a bit ambiguous. Do you mean that you want the ATO to operate with the time limit, but only at night? If so then you could put it in either, but I think it makes more sense in the virtual outlet.

[ATO_Allow]
OSC 00:00/03:00/57:00 Then ON
If Outlet [lights] = ON Then OFF

[ATO]
Fallback OFF
Set OFF
If Switch1 CLOSED Then ON
If Outlet Maintenance = ON Then OFF
If Outlet ATO_Allow = OFF Then OFF
If pH > 8:50 Then OFF
Defer 00:10 Then ON

Sorry for the confusion, you are correct i want the ato to work during the night. This is what i have and seemed to work last night, do yo see any issue with the followin:

ATO Outlet
Fallback OFF
Set OFF
If Switch1 CLOSED Then ON
If Outlet ATO_Allow = OFF Then OFF
Defer 000:05 Then ON

ATO Allow
OSC 000:00/000:30/029:30 Then ON
If Time 14:00 to 23:00 Then OFF

Thanks for your time

Yup, that should work just fine.
