Rola-Chem 554230 ORP Digital Controller User Manual
Page 11
* Controllers are designed to maintain set-points. Do not expect Controllers to make
major adjustments—major changes should be done manually.
* Pump/feeders must be large enough to reach desired set-points in a relatively short
time. Automation using controllers may require larger feeder or more concentrated
chemicals than system that uses continuous time controlled feeding (i.e. feeders
only).
