it is possible to activate the relais on low level indication instead of the high indication. I want to use it when my level is to low so that a pump fill up the waterbarrel.
what is the easyest way to do this.

Hi
You can choose between a NC(normally closed) or an NO (Normally open) contact.
In this case you should use the NC contacts.
When the relay is activated the relay will go open then.

hello, i understand how it works with NO and NC. Butt is it possible to see on the relais led when the the water level is low. that the led of relais is on when the water is low.
Now the relais led is on when the water is high, i want it the other way around. just for indication that the relais is working.
