Generally, automating an existing body of water with existing feeders will require the output of the feeders be increased accordingly. If feeders are unable to keep up with demand in a short period of time, automation becomes ineffective. ROLA-CHEM Digital Controller PN 554135 12/26/18...

The flow switch light on the face of the controller is also a power light that shows that the controller is connected to a live power source. If the terminal does not have a closed circuit, the controller will not turn on. ROLA-CHEM Digital Controller PN 554135 12/26/18...
Note: It is recommended that an inline filter be used to help keep the Globe Flowcell (including probes) and flow switch free from debris. Debris may cause obstruction in flow switch and prevent the switch from functioning. ROLA-CHEM Digital Controller PN 554135 12/26/18...
Description of Controls section). Then select the desired Set Level, Feed Time and Hi and Low Alerts. Adjust Consecutive Feed Alert Limit if Set Level is not met within preset limit as indicated by the Digital Display flashing. –See appendix for details.

The controller must be in this mode for the feeders to maintain the desired parameters. Note: When using the RC554XP or 554000 controller with ROLA-CHEM pumps, the pump switch should be in the CONTINUOUS position (not Timed or Off).
* 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).

The Consecutive Feed Alert Limit period can be set from 20 to 180 minutes on model RC554XP (default is 20) and can be independently set for both pH and ORP. The available range on model 554000 is 10 to 99 (default is 10).
