Without knowing how the ATO was done in the video that you watched I cannot know if its the same as a Tunze or not. Perhaps post a link to the video.
Here is my ATO program. Switch 4 and 1 are float sensors in the sump and Switch 3 is a water on the floor sensor. The ATO pump comes on when the sump switches are in the down position and runs for at least 30 seconds at a time. Its nothing special and there are other ways of doing it. The comprehensive users manual available on Neptune's site outlines a different method.
Set ON
Min Time 000:30 Then ON
If Sw4 OPEN Then OFF
If Sw1 OPEN Then OFF
If Sw3 CLOSED Then OFF
Outlets are numbered from left to right, top row and then lower row like this:
1234
5678
