Hello , I bought a level sensor for my profilux 3t . I make a change of semiautomatic water and I would like to leap an alarm when the water reaches a level . I can program the profilux to overflow and works right . but then the water level is maintained until the next change of water. It could be programmed so that only the profilux alarm sounds until turned off and not sound until you change the water ( I do not use automatic water change is manual) .

I would also like to buy a water sensor on the floor. Is it possible to connect this sensor on the same level sensor connector with a cable Y?
Thank you
