HAYWARD HCC2000 HCC Automated Controller

Product Information: HCC 2000 Automated Controller

The HCC 2000 Automated Controller is a chemical automation system designed for pools and spas. It allows for the automatic monitoring and control of water chemistry, specifically the oxidation-reduction potential (ORP) and flow rate. The controller comes with components such as the ORP Sensor, Flow Sensor, and Flow Cell, which work together to ensure optimal water quality.

Components of an HCC 2000 Automated System

• ORP Sensor: Samples water from the filtration system and measures the oxidation-reduction potential (ORP) of the water. ORP is an indicator of sanitizer activity and bacteriological water quality.
• Flow Sensor: Monitors the flow rate across the  pH and ORP sensors. It signals the controller to disable automated chemical feeding when the filtration system is off or low recirculation flow is detected.
• Flow Cell: Provides a convenient mounting location for the pH, ORP, and Flow Sensors. It ensures optimal hydraulic conditions for accurate sensor performance and longevity.

Product Usage Instructions

SECTION 1. CHEMICAL AUTOMATION WITH THE CC 2000

A pool operator typically checks and adiusts pool or spa water chemistry hourly at best. The HCC 2000 continuously monitors pH and sanitizer activity, constantly adjusting the feeding of chemicals on a basis proportional to the demand. The results include elimination of “human error”, accurate and reliable maintenance of chemical levels twenty-four hours a day, compliance with Health Department chemistry standards, reduced burden on operating staff, and a reduction of chemical usage and costs.

The following graph (Illustration 1.) compares typical chlorine levels when chemistry is adjusted manually versus automatically with the HCC 2000 controller.

SECTION 2. COMPONENTS
of an HCC 2000 AUTOMATED SYSTEM The following is a description of the components incorporated in a typical HCC 2000 controller system:

The pH Sensor samples water from the filtration system and sends signals to the controller indicating the acidity of the water. The ideal pH range for pools and spas is 7.4 – 7.6. The HCC 2000 controller is preset from the factory to maintain pH 7.5. If pH is maintained below 7.4 (too acidic), eye irritation, corrosion of equipment, and damage to the pool or spa surface can occur. If pH is maintained above 7.6 (too alkaline), sanitizer activity is reduced, water may become cloudy, and eve irritation may result.

The ORP Sensor samples water from the filtration system and sends signals to the controller indicating the oxidation-reduction potential (redox) of the water. ORPis ar actual measure of sanitizer activity (chlorine, bromine, ozone, etc.) bacteriological water quality rather than an expression of chemical residual levels The HCC 2000 controller is preset from the factory to maintain ORP at 650 millivolts.

The Flow Sensor (required monitors the rate of flow across the pH and ORP sensors and signals the controller to disable automated chemical feeding during periods when the filtration system is off or low recirculation flow is detected.

The Flow Cell provides a convenient location for mounting the pH, OR and Flow Sensor while ensuring ideal hydraulic conditions to maximize sensor performance and life.

The HCC 2000 controller unit scans and interprets the signals from the pH and ORP probes, displays water quality readings in digital format, and activates chemical feeders in proportion to the demand required to maintain setpoint pH and OR levels. The unit incorporates audible and visual safeguard alarms for out of range conditions, calibration adjustment for pH, and mode selections to manually feed or disable feeding for either channel. The HCC 2000 controller unit also features an internal micro-computer for unsurpassed accuracy, adaptability, and ease of use. All user- entries and adjustments are made through the touch-screen interface front panel.

INSTALLATION PROCEDURES
The key to a successful flow cell installation is in the plumbing. A pressure differential is required to allow clean, untreated water to pass through the flow cell and across the sensors. We recommend using a pressure-suction “loop” line.

1. Turn offheater, chemical feeders, pump, and any other related equipment. Relieve pressure from filtration system.
2. Select a convenient mounting location for the controller unit which will meet the following criteria
   • A. Facilitates a combined (influent and effluent) maximum tubing run of 30°
   • B. Located a minimum often feet from pool or spa.
   • C. GFI protected power source available.
   • D. Easily accessible to pool or spa operator.
   • E. Away from corrosive materials and physical hazards.
3. Securely mount Controller and PVC Backboard on vertical wall.
4. Drill and tap a 1/4″ NPT port at a location just down-stream of the filter, but up- stream from any chemical injection point. Install a tubing connector, and run flex tubing to the influent flow cell port.
5. Drill and tap a 1/4″ NPT port at a location subject to vacuum or reduced pressure. Install the remaining tubing connector and run flex tubing to the effluent flow cell port.
6. Cut a 3″ to 6″ length of flex tubing and insert into the sample stream port.
7. Remove pH and ORP sensors from the plastic storage bottles and save bottles and storage fluid for future use. Thread sensors into flow cell.
8. Remove BC protective covers from left side of controller unit and store for future use. These covers protect the controller unit from electro-static discharge (ESD) and should be used whenever handling or transporting the controller unit.
9. Connect the pH, ORP and Flow sensor cables to the controller unit as labeled. Sensor cables are constructed from a specialized material – never cut or splice.
10. If new or additional chemical feeders are to be used with the controller, install according to manufacturers instructions at this time.
11. Connect chemical feeders to the controller as labeled.
12. Check all electrical and mechanical connections. Resume filtration system operation and check for any leaks.

ILLUSTRATION 2. HCC 2000 INSTALLATION DIAGRAM

Now that your new controller has been physically installed, water chemistry should be tested and adjusted prior to initiating automated control of the pool or spa. Confirm that your pool or spa water conforms to the following ranges before powering on and setting up the HCC 2000.

The above table indicates generally accepted guidelines. Always maintain water chemistry according to standards set by your local or State Health Department.

Hayward® water quality controllers maintain sanitizer levels (chlorine, bromine, ozone, etc.) based on ORP. Although ORP is a superior index of water quality compared to part per million sanitizer residual levels, factors such as pH, cyanuric acid concentration and total dissolved solids can affect sanitizer residual readings relative to ORP.
Hayward strongly recommends establishing desired pH, sanitizer residual, calcium hardness, total alkalinity, temperature and cyanuric acid levels prior to initiating automated control of the pool or spa. The ORP setpoint will need to be changed periodically as described later in this section if the goal is to provide consistent sanitizer residual levels rather than consistent control of ORP.

Once desired start up chemistry parameters have been established, you are ready to set the HCC 2000 to automatically maintain pH and sanitizer levels. Please refer to Illustration 4 for controller unit button designations. Button designations appear in bold type.

Selecting Acid or Base Feed
The HCC 2000 is preset from the factory to operate in the acid feed mode (when pH exceeds the setpoint, the pH chemical feeder is activated). If the sanitizer used at vour facility causes the pH to decrease vou must select base feed mode. To switch the controller between acid feed and base feed modes, perform the following steps.

1. Press and hold the Hidden Button (#1) for five seconds to enter advanced setup mode.
2. Scroll to pFD and press the enter key. Scroll to select A for acid feed or B for base feed. Press the Enter key to set your selection, then press the Hidden Button (#1) again to return to normal operating mode. As the unit powers on, the digital pH readout will display an “A” or “B” indicating whether acid feed or base feed mode has been activated.

HCC 2000 CONTROLLER
The HCC 2000 controller unit is virtually maintenance free. Cleaning of the enclosure, front panel and flow cell can be performed using a clean, soft cloth moistened with mild soap and water solution or glass cleaner. Use of abrasives or harsh chemicals may damage the enclosure and membrane switch panel.

WATER MAINTENANCE
Always test and record water chemistry readings in compliance with Health Department requirements using a quality manual test kit. Calibrate pH periodically as described earlier in this manual.
It is important to note that changes in pH, cyanuric acid concentration, total dissolved solids, and use of additional or alternative sanitizers will all affect the primary sanitizer residual level relative to ORP. It is important to maintain total alkalinity on a regular basis to ensure pH stability. To maintain a consistent sanitizer residual in parts-per-million (ppm), periodically adjust the ORPsetpoint.

PRECISION CALIBRATION
The HCC 2000 controller provides instrument-grade accuracy which exceeds that of most liquid-standard water testing kits. Therefore, it may be preferable to calibrate pH using commercially available reference solutions.

SENSOR MAINTENANCE
The sensors must be clean and free from oil, chemical deposits and contamination to function properly. After saturation in pool or spa water, the sensors may need to be cleaned on a weekly or monthly basis depending on bather load and other facility- specific characteristics. Slow response, increased need to calibrate pH, and inconsistent readings are indications that the sensors are in need of cleaning.
To clean the sensors, disconnect from the controller and carefully remove them from the flow cell. Clean the reference junction (the white teflon ring at the bottom of sensor body) with a soft tooth brush and regular tooth paste. A household liquid dishwashing detergent may also be used to remove any oil. Rinse with fresh water, replace teflon thread-seal tape, and reinstall sensors. Hand tighten only.
Never allow a pH or OR sensor to dry completely. Drying will damage the reference junction and void the sensor warranty.

SENSOR REPLACEMENT
CC pH and ORP sensors are engineered to provide the highest performance and longest possible functional service life. If properly cleaned sensors provide unstable readings or require excessive calibration, the pair of sensors should be replaced. For optimum controller performance, replace with genuine HCC Professional Series sensors PRO15-2 and PRO25-2.

SENSOR STORAGE
Exposure to atmospheric conditions will cause the sensor tips to dry out. Always remove and properly store sensors in the soaking caps provided if sensors are to be removed or stored for one hour or longer. Although Hayward® sensors are freeze- resistant, they must be protected from freezing temperatures when not in use.
Store sensors in the soaking caps provided, making sure that each container is filled with the original storage solution or clean water. If the storage containers have been misplaced, store sensors individually in small glass or plastic containers with clean water covering sensor tips.

CONTROLLER STORAGE
The controller unit is subject to damage by electro-static discharge (ESD) when the sensor cables are disconnected. Always reinstall the BC protective covers prior to storing or transporting the HCC 2000 controller unit.

WINTERIZATION
The sensors should be prepared for storage as outlined above and protected from freezing temperatures. Although the HCC 2000 controller is designed to withstand a broad temperature range, winter storage in a secure location is desirable.
The flow cell and poly tubing must be drained prior to exposure to freezing temperatures. Either purge all water using compressed air or thoroughly drain through the valve ports and tubing connections.

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 pronerly connected to their respective BNC connectors on the controller unit.
2. Ensure that filtration system is functioning properly, flow is adequat 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.
