Page 4 of 20 Control Station Rev. A GENERAL The Control Station is a pool equipment control and treatment regulation system. The Control Station allows you to control the filtration system (pump) as well as the peripheral equipment (heat pump, lighting, etc.). It also allows you to treat your pool effectively via liquid chlorine injection. The Control Station is suitable for treating most residential swimming pools. The quantity of chlorine required to treat a pool correctly varies according to the number of bathers, the rainfall, water temperature and the cleanliness of the pool... INSTALLATION Description

probe Measuring chamber 2 x Peristaltic pumps ORP probe Screen remote kit (Optional) Wi module Temperature probe The fuses are either on the side or the bottom of the control box.USE ONLY GENUINE REPLACEMENT PARTS Page 5 of 20 Control Station Rev. A Wall-mounted installation Fix the box and the measuring chamber on the wall (optional). The box must be installed in the equipment room (dry, temperate, ventilated). Caution, acid vapours can cause irreversible damage to your device. Position the treatment product tanks accordingly. The Control Station must be fitted a minimum horizontal distance of 3.5 m (or more, if required by local regulations) from the pool. The box must be placed vertically on a flat surface, with the cables downwards. As this box is also used to evacuate heat (heat dissipation from internal components), it is important that the four sides of the box remain unobstructed. Do not to install the Control Station behind a panel or in an enclosed space. Before installing the control unit in the intended location, check that the power cord can reach the protected outlet. Disconnect the pool filtration pump before starting the installation. The system must be installed in accordance with the standards currently in force in the country of installation. The control box must be fitted a minimum horizontal distance of 3.5 m (or more, if required by local regulations) from the pool, within 1 m of a protected outlet. Install and use the product at an altitude below 2000 m. The flow switch must be installed on the return pipe directly in line with and upstream of the treatment product injection point. Allow a 25 cm straight section before the flow switch. A hole should previously have been drilled in the pipe to allow the flow switch to pass through. Screw the flow switch into the saddle clamp, taking care to seal with Teflon. Then install the clamp on the pipe. The flow switch must be installed in the direction of operation to ensure that it is tripped by the flow from the filtration pump. The device used to inject the treatment products (acid, etc.) must be installed last on the water return line, after any equipment (heater, etc.). A hole should previously have been drilled in the pipe to allow the treatment product to pass through. Install the saddle clamp and screw the injection valve into the saddle clamp using the adapter provided. Seal with Teflon. Use the transparent PVC hose for suction (between the tank and the peristaltic pump) and the semi-rigid white polyethylene tube for injection (between the peristaltic pump and the injection valve). All the metal components of the swimming pool can be connected to the same earth as per local regulationsUSE ONLY GENUINE REPLACEMENT PARTS Page 6 of 20 Control Station Rev.

Place the flat gasket on the pipe fitting and insert the assembly into the hole, as illustrated below. Tighten the fitting with the clamp provided. Once the fitting has been secured to the pool pipe, insert the hose firmly into the pipe and tighten the retaining nut by hand. Clamping collar Retai- ning nut Pipe tting Flat gasket Installing the pH and ORP probes on the measuring chamber The pH and ORP probes are "wet" packed and protected by plastic caps. The probes must always remain wet. If the probes are allowed to dry, they will be permanently unusable (not covered by the warranty) and the pH-ORP test kit will be ineffective. Remove the pH and ORP probes from their plastic protective caps and set the caps aside for later use (wintering). To ensure that the probes remain wet at all times, fill the measuring chamber with pool water before installing the probes. Apply a length of Teflon tape to the probe threads. Tighten the probes by hand only. Check that they are watertight at startup. If the probes leak, do not tighten them further, but remove the Teflon tape and apply a new one. After installation, check that the probes are constantly in contact with the water in the pool. When the filtration pump is not running (even for long periods), the water remaining in the chamber may be sufficient to protect the probes.

A Assigning speeds Whatever the filtration mode (Manual, Automatic, Smart, Heating or Intelligent), one of the three operating speeds (V1, V2 or V3) can be selected, thus providing a high degree of flexibility for setting and adjusting the water flow according to the equipment. The device will first have to be configured to take the variable-speed pump into account (see the section entitled "Setting the pump type"). The speed assigned to the "antifreeze" mode is V2. Note: We should point out that the speed of all pool devices requiring a minimum water flow that is appropriate to their correct operation must be set manually before being stored in the memory and used by the Control Station (heat pump, chlorinator, etc.). See the variable-speed pump instructions for setting all the parameters related to its operation and safety. Connecting the Wifi option The Wifi module must be installed in the equipment room (dry, temperate, ventilated) and located within reach of the wireless network cover to which it will be connected. Switch off the device before connecting the module. Plug the Wifi module connector into the RF / WIFI connector on the Control Station card. Installing the screen wall-mounting kit (not supplied) Remove the screen from the box and unplug it. Plug the extension connector into the DISPLAY connector on the Control Station card. Plug the other end of the extension into the screen after first passing the cable through the wall bracket. Fit the cover (supplied) over the front of the Control Station to replace the screen.USE ONLY GENUINE REPLACEMENT PARTS Page 12 of 20 Control Station Rev. A Chemical water balance The water must be balanced manually BEFORE the device is started up. The following table summarizes the concentrations recommended by Hayward. Your water should be checked regularly to maintain these concentrations and minimize surface corrosion or deterioration. CHEMISTRY Recommended CONCENTRATIONS Free chlorine 1.0 to 3.0 ppm pH 7.2 to 7.6 Cyanuric acid (Stabilizer) 20 to 30 ppm max. (Add stabilizer only if necessary) 0 ppm in indoor pool Total alkalinity 80 to 120 ppm Water hardness 200 to 300 ppm Metals 0 ppm Saturation index -0.2 to 0.2 (preferably 0) Saturation index The saturation index (Si) gives us information about the calcium content and alkalinity of the water; it is a water balance indicator. Your water is correctly balanced if the Si is 0 ± 0.2. If the Si is below -0.2, the water is corrosive and the coating on the pool walls may be damaged. If the Si is above +0.2, stains may appear. Use the table below to determine the saturation index. Si = pH + Ti + Ci + Ai - 12.1 °C °F TiHardness(Calcium) Totalalkalinity

Use: Measure the pH of the pool water, the temperature, water hard-ness and total alkalinity. Use the table above to determine Ti, Ci and Ai in the formula shown above. If the Si is equal to 0.2 or more, stains may appear. If the Si is equal to -0.2 or less, corrosion or deterioration may occur. - 0.20.20 CORROSIONSTAIN

A Filtration 1 Filtration modes. 2 Manual: Allows the ltration process to be turned on and off manually. 3 Filter cleaning: This mode is used to backwash the lter. 4 Automatic: In this mode, ltration is turned on according to the start and end times set in the time slots. The time slots always operate on a daily basis.5 Smart*: This mode is based on the automatic mode, with its three ltration intervals, but the ltration times are adjusted according to the temperature. This is done by setting two temperature parameters: the maximum temperature, above which the ltration times will be determined by the time slots, and the minimum temperature, below which ltration will be reduced to ve minutes, the minimum operation period. Between these two temperatures, the ltration times will be staggered linearly. The antifreeze mode can be activated to turn the ltration on if the water temperature falls below 2°C. 6 Heating : This mode acts in the same way as the automatic mode, but it can also operate via a relay that controls the temperature. The set point temperature is determined in this menu and the system operates with a hysteresis of one degree (for example: if the set point temperature is 23°C, the system will start up when the temperature falls below 22°C and shut down only when it rises above 23°C). Heating control OFF: The heating operates only during the ltration periods congured. Heating control ON: Keeps the ltration on after the ltration period has expired if the temperature is below the set point temperature. When the setpoint temperature is reached, the ltration and heating stop and only resume when the next programming period begins.7 Intelligent*: In this mode, the user has two operating parameters: Select the required water temperature and the minimum ltration time (minimum two hours and maximum 24 hours). The ltration will operate for at least ten minutes every two hours to check the temperature. The minimum ltration time selected is divided into twelve sections that are added to its ten minutes. Example 1: Over twelve hours, the time is divided between the twelve times a day when the ltration starts up to check the temperature. Example 2: (12 hours x 60 minutes) / 12 = 60 minutes every two hours. This is the ltration and heating period every two hours. If the programmed ltration period ends and the required temperature has not been reached, the ltration and heating remain on until the required temperature is reached. To minimize the number of hours during which ltration operates each day, this additional time will be deducted from the next ltration periods occurring during the rest of the day.

Page 18 of 20 Control Station Rev. A Setting the redox level The redox level tells you the oxidation potential, i.e. the disinfectant capacity of the water. Setting the redox set point is the last step in setting the Control Station. To nd the optimum redox level for your pool, follow the steps below:

1) Start up the pool ltration system.

2) Add chlorine to the swimming pool until it reaches 1 to 1.5 ppm. This level is achieved with (approximately 1 to 1.5 g/m

of water). The pH level must vary between 7.2 and 7.5.

3) After 30 min. Check whether the level of free chlorine in the pool (manual DPD1 test kit) is between 0.8 and 1.0 ppm.

4) Look at the redox value on the screen and enter it as the redox set point.

5) The next day, check the free chlorine levels (manual DPD1 test kit) and the redox level. Increase / reduce the setting, if required. Remember to check all your water parameters at regular intervals (2-3 months) (see table) and adjust the redox set point according to the steps listed above. Setting the Wifi module

1 Internet: Once the module is connected, switch on the device. A Network menu appears in the Settings menu. 2 Wi: Select the Wi menu to start an automatic search for available networks. 3 Choose the relevant available network. 4 Enter the password for this network via the keyboard. Use the up/down arrows to move the cursor vertically and the +/- buttons to move the cursor horizontally. To conrm, press OK. 5 Conguration: If you want to congure your connection manually or if automatic conguration fails, you can change the network parameters in this menu. 7 Status: Displays information about your current connection. 8 Test connection: Checks that your connection has been established.

When the module is connected to the Wi network and the two LEDs are on continuously (steady), you can register at poolwatch.hayward.fr. Get your ID Node (see below) and follow the registration process. Once you have registered, you can monitor all your Control Station parameters remotely.

Page 19 of 20 Control Station Rev. A SERVICING During the rst 10-15 days, your system will require more attention: - Check that the pH remains at the ideal level (7.2 to 7.4). - If the pH is exceptionally unstable and uses a lot of acid, check the alkalinity (see table). If the balance is highly unstable, contact your pool installer/builder. REMEMBER that the system needs a certain amount of time to adapt to your pool and will require additional chemicals during the rst 3-5 days. The pool must be regularly maintained and the skimmer baskets emptied whenever necessary. Also check that your lter is not clogged. DOSING PUMPS: Check the levels regularly to ensure that the pumps do not run on empty. The dosing pumps must be checked and serviced at regular intervals. Servicing the probes The probes must be clean and free from oil, chemical deposits and contamination to function properly. As they are in continuous contact with the water in the pool, the probes may need to be cleaned weekly or monthly, depending on the number of bathers and other specic pool characteristics. A slow response, more frequent pH calibration and inconsistent readings indicate that the probes need to be cleaned. To clean the probes, turn off the power to the Control Station. Unplug the probe connectors from the control box, unscrew the probes and carefully remove them from the chamber. Clean the probe bulb (white ring at the bottom of the body of the probe) with a soft toothbrush and regular toothpaste. A household washing-up liquid detergent may also be used to remove any oil. Rinse with fresh water, replace the Teon tape on the threads, and reinstall the probes. If the probes continue to give inconsistent readings or require excessive calibration after they have been cleaned, they should be replaced. Wintering The ow switch, probes and pool piping run the risk of being damaged if the water freezes. In regions that experience long periods of cold weather, be sure to drain all the water from the pump and lter and from the supply and return pipes before winter. Do not remove the control unit. Probe storage The end of the probes must always be in contact with water or a solution of KCl. If they are removed from the measuring chamber, they should be stored in the plastic caps provided (lled with water). If the storage caps have been mislaid, the probes should be stored separately in small glass or plastic containers with their ends immersed in water. The probes must always be in a frost-free environment.USE ONLY GENUINE REPLACEMENT PARTS Page 20 of 20 Control Station Rev. A TROUBLESHOOTING GUIDE No display Check that the On / Off switch is on. Check the connection cable between the display and the control box. Check that the external 630 mA fuse is not defective. Check the power supply: 210-230 V 50 Hz. If the problem persists, contact your pool installer/builder. Excessive chlorine Check the redox setting. Check the redox probe and calibrate, if necessary. Impossible to attain a free chlorine level of 0.8 ppm Increase the ltration time. Increase the ORP set point. Check the level of isocyanuric acid in the pool. Check that the reactive agents in your test kit are not out of date. If the temperature or the number of users increases. If the pH is above 7.8, it must be adjusted. Alarm AL3: dosing pump stopped The maximum time required to attain the pH or ORP set point has been reached. The disinfectant or pH dosing pump is stopped to avoid overdosing. Please carry out the following checks to avoid equipment failure: Check that the can of liquid pH adjuster or liquid chlorine is not empty. Check whether the pH read on the machine corresponds to the pH in the pool (use a pH analysis kit). Otherwise, calibrate the pH probe or replace it, if necessary. Check that the pH pump is running normally. Check and adjust the time of AL3 according to the size of your pool. Check that the liquid chlorine pump is working correctly. Check the ORP probe using a standard solution and replace the ORP probe if required. To delete this message and reset the dosing values, press the key.
