ATO using a single probe and a timer

HI there

Can someone help me setup a ATO using a timer and one level control?

Im not looking at setting up the traditional ATO as Im unable to exclude it from my water change schedule

I will elaborate
Currently my AWC is setup using a series of timers due to the fact that I need to turn off my Skimmer, and RTN pump in order to do my change
Using the process it doesn't look like I can easily setup my ATO in conjunction with my AWC's

So my question is:
How can I use a timer instead to do a ATO once or twice a day using one level probe monitor (which I have specifically set aside for this task)?
The other option is to have it run constantly, but be excluded during the AWC or maintenance periods

Any help would be greatly appreciated

Thankyou

Actually, I have a similar setup like you, two level control - one for ATO ( controller by time ) and upper level control during AWC, the other one for low level controller to turn off the drain pump. So far working perfectly ... so actually what is the problem for the ATO ?

in the level control settings:

uncheck "ATO always"
then set the timer which determines when ATO should be active

Thanks everyone
I think I have it setup correctly, however when it now activates and the level is showing as 'Fill' nothing happens. All I get is an error on the level after the 1 minute timeout
The Socket function is currently set to AWC and ATO

Any ideas?

If I invert the level meter, the error doesnt occur (I assume thats because it thinks its at the correct level)

the socket function is "Fill", right?
you used the correct level control channel?

I think you better post screenshot of the relevant question, this way we need not to ask so much

Thankyou for your help and assistance
I'm pretty sure that I have attached all the relevant screen shots

Please let me know if anything else is needed

Appreciate the help

in socket function: it must be index 3 and not 1

Thankyou very much !!!
Will that effect the AWC setup I currently have?

I just checked and the method above did indeed interrupt my water change
The change didnt occur as it normally does

Any ideas?

Bump...

Please help

Thankyou ;)

Is there any chance someone from GHL can help?
Currently my AWC are not working due to the changes I was advised to make above, and I need to ensure that the changes occur to avoid any dramas with my levels

Thankyou

Can you please describe what exactly does not work?

When shall your water change take place (time) and how long will it last?

Is the socket for filling the ATO the same as for filling during the AWC?

Apologies for the delay in getting back to you
I did post the times in the screen shots on the first page

Essentially the water change occurs every X days @ 750PM
At 750PM the skimmer and RTN pump turns off
Water Change Occurs
RTN pump gets turned back on
Wait 2 mins, then turn skimmer back on

In regards to your question, yes the exact same source is being used for the AWC as the ATO
The function is set to both AWC/ATO however only one function seems to work

The issue I have is that when I have made the changes recommended by GHL is prior posts, yes the ATO works perfectly, however what doesnt work is the AWC. The socket doesnt turn on when water is needed after the AWC water drain and instead I get a error on the level

As I can see from your settings, the ATO is switched off from 07:55 pm to 08:30 pm.
Could it be that the water change perhaps lasts longer than 08:30? Then it would get mixed up with the ATO.

No definitely not
The WC drain is finished in 5-10mins (MAX)

Any progress on this?

ok, let's start from the beginning and forget the previous posts, I got too confused

please answer short but precisely

- what do you want to achive?
- how did you do that?
please post screenshots of ALL relevant settings
- what is the exact problem?

BTW - the ATO and AWC works with all channels with any socket, I just tested it (again) to be 100% positive

Apologies for the delays

OK, so what I currently have is one set of sensors set up for AWC.
The AWC is setup to shutdown the Skimmer first, turn off RTN pump, then wait for X period of time, activate the water pump #2 to empty the tank to a certain level, then activate pump #3 to fill with natural sea water. Once level X is reached, return pump is turned back on, wait X minutes then skimmer turned on.

This worked fine until I added another level meter for ATO
I have a 3rd level meter that sits in another part of the sump. This is used for ATO and is dis-activated for when AWC's occur
The issue is that either the ATO or AWC occurs, not both.

I have attached screen captures of all necessary (I think) settings of the Profilux.
Id really appreciate any help as currently I'm doing the water changes using manual switching to get around the issue.

Thankyou in Advance
