How to auto shut off aquatec 8852 when feeding bucket is empty?

[Fun4stuff]

All the auto shut off setups I’ve seen seem to work based on pressure in holding tank that fills with permeate (which i don’t have) or some kind of float in the permeate tank.

I use a GRL8-02 level control relay to turn on and off my RO automatically. Its a simple device to wire up and uses a simple 2 wire probe in your feed tank. When the sap drops below whatever depth you set that at it will turn off. You can do the same thing with an upper limit probe to turn it on.

I have mine set up with some 3 way switches to I can select On, upper limit on/lower limit off, or just lower limit off.
