Rola-Chem 554200 pH Digital Controller - Manual (Page 11)

5.3 Set-points not being reached or maintained
*
Factory setting for feed time is 0.6 sec on with 5 minute delay. Feeders may require
longer feed time. If time is too short, set-points will not be maintained. If time is too
long, overfeeding chemicals will occur. Correct time is dependent of multiple factors
such as pool/spa water volume, feeder output, chemical concentration and chemical
needs.
* 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).
