Why set so short the max. on time? Usually it be set just longer than the refill time.

so what you are saying is to increase the amont of time for exemple to 30 sec ?

because when i did to much fresh water going into the aquarium

Since you have a float switch, fresh water will stop pumping in when the water level reach the float switch which deactivate the ATO, so just set the max on time to cover the normal fill-up time plus for let's say extra 5 sec is OK.

thanks for your answer
can i ask you a other question for a automatic water change system does it better to use float switch or optical sensor ?

Both are OK, I used one optical and one float switch for AWC.
