Evaporation changes dissolved solids concentration. Replacing it automatically keeps the water volume, and therefore the chemistry, steady between changes.
What I've learned
·Automatic top-off removes a confound from the conductivity trace: a rise then reflects consumption rather than evaporation.
Installation
Not yet documented.
Configuration
·Switched through a controller outlet
·Tops off with RODI water
