Both pH and ORP digital readouts display illogical values.
1. Sensor cable connections may be reversed. Ensure that sensor cables are properly connected
to their respective BNC connectors on the controller unit.
2. Ensure that filtration system is functioning properly, flow is adequate, and water chemistry is
in balance.
ORP chemical feeder is not activated as expected.
1. Make sure “auto” ORP feed mode is selected.
2. Check ORP setpoint.
pH chemical feeder is not activated as expected.
1. Ensure that acid/base feed mode is properly set for your chemical feeding requirements.
2. Make sure “auto” pH feed mode is selected.
3. Check pH Setpoint.
Chlorine or bromine residual is too high or too low.
1. pH, cyanuric acid concentration, total dissolved solids, and use of additional or alternative
sanitizers will all effect the sanitizer residual level relative to ORP. Consider the effect of any
chemicals recently added to the pool or spa.
2. Check and adjust ORP setpoint.
pH requires frequent calibration.
1. Clean the sensors as outlined in the maintenance section. If sensors continue to provide
unstable readings after cleaning, replace sensors.
pH or ORP readings are inconsistent or slow in response.
1. Ensure that sensor cables are properly connected to their respective BNC connectors on the
controller unit.
2. Clean the sensors as outlined in the maintenance section. If sensors continue to provide
unstable readings after cleaning, replace sensors.
3. Check to ensure that all electrical equipment in the facility pump room is properly bonded.
pH or ORP chemical feeder runs continuously.
1. Make sure “auto” feed mode is selected.
2. Ensure that chemical feeders are properly connected to their respective connectors on the
controller unit.
pH or ORP feeding overshoots the setpoint.
1. Ensure that each chemical feeder is properly sized.
2. Check concentration of sanitizer or pH chemical.
pH or ORP feeding does not reach the setpoint.
1. Ensure that each chemical feeder is properly sized.
2. Check concentration of sanitizer or pH chemical.
3. Check chemical feeders and injection points for proper operation.
