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
