Hey Guys
Some of you asked me for a wiring diagram for a "auto top up RO system'.
I will post it here for everybody to use.

This diagram includes two float switches which the bottom one will be used to start/ open the pump/solenoid.
The second float switch will be used to close/stop the pump/solenoid.
Only use 12 volt when connecting float switches




11 pin relay was used in this diagram but a 8 pin will also work.
only two C/O (common operation) will be used.

Float switch 1 is connected in N/C (Normally Close)
Float switch 2 is connected in N/O (Normally open)

Operation is as follows...
Water level will get empty, float switch 2 will close and pump/solenoid will start/open.

Drum will fill up water until float switch 1 is open and pump/solenoid will stop/close.



Enjoy and be safe.
