Troubleshooting Each HCC 2000 controller is manufactured to the highest quality standards and then thoroughly tested before leaving the factory. State of the art design and fabrication technology ensure years of trouble free operation. Most apparent malfunctions can be solved through the following corrective actions: No lights are illuminated when controller is powered on. 1. Check circuit breaker and/or receptacle for proper operation. Connect to functional grounding-type GFCI protected power source. 2. Check for damaged power cord or connector. Alarm light(s) and tone are observed. 1. Ensure that filtration system is functioning properly, flow is adequate, and water chemistry is in balance. 2. Ensure that sensors and power cables are properly connected to their respective connectors on the controller unit. 3. Check chemical feeders for proper operation. 4. Ensure that flow sensor is properly installed and connected. 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 affect 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. 19 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS

Troubleshooting
Each HCC 2000 controller is manufactured to the highest quality standards and then thoroughly
tested before leaving the factory.
State of the art design and fabrication technology ensure years of
trouble free operation.
Most apparent malfunctions can be solved through the following corrective
actions:
No lights are illuminated when controller is powered on.
1.
Check circuit breaker and/or receptacle for proper operation.
Connect to functional ground-
ing-type GFCI protected power source.
2.
Check for damaged power cord or connector.
Alarm light(s) and tone are observed.
1.
Ensure that filtration system is functioning properly, flow is adequate, and water chemistry is
in balance.
2.
Ensure that sensors and power cables are properly connected to their respective connectors
on the controller unit.
3.
Check chemical feeders for proper operation.
4.
Ensure that flow sensor is properly installed and connected.
Both pH and ORP digital readouts display illogical values.
1.
Sensor cable connections may be reversed.
Ensure that sensor cables are properly con-
nected 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 affect 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.
