Hayward Aqua Plus Model: PL-PLUS Operation - Page 12

Set Day and Time Wednesday 1100::3377PP Set Day and Time Wednesday 37 Set Day and Time Wednesday 10: P Adjust the current day of the week Move to hours setting Adjust the current hour (including AM/PM if applicable) Move to minutes setting Adjust the current minute Move to previous/next menu item Use this function to set the current day of the week and time. These values are used for all the automatic timeclock functions of the Aqua Plus and are also displayed as part of the default menu. The Aqua Plus is designed to keep the clock running during power outages lasting less than 7 days. If power has been off for longer than 7 days, then the time may have to be reset. Display Light On for 60 sec Toggle between Always On and On for 60 sec. Move to previous/next menu item This function controls the backlight on the display. If the "60 seconds" option is selected, then the backlight will automatically turn off 60 seconds after the last key is pressed and will stay off until next time a key is pressed. Note that the Display Light selection only applies to the display keypad that you are currently using. Other display/keypads will not be affected. In other words, you need to individually set this option for each display/keypad in the system. Beeper Enabled Toggle between Enabled (default) and Disabled Beeper Move to next menu item When "Enabled", the keypad will beep every time a key is pressed. If this audible indication is not desired, select "Disabled". This function only applies to the display/keypad that you are currently using. You need to set this option for each display/keypad in your system. NOTE: This function is not supported on all display/keypads. If the "Enabled" selection is not blinking, then the current software revision of that particular keypad/display does not support the option and it will default to Beeper Enabled. 9 Chlorinator Operation / Water Chemistry General Water Chemistry Salt is required only if you are using the chlorinator features on the Aqua Plus Control. If you are NOT using the chlorinator, it is recommended that you follow all of the other chemistry recommendations besides salt. Refer to the description of the Aqua Plus configuration menu for information on enabling/disabling the chlorinator (see page 13). Water Chemistry The table below summarizes the levels that are recommended by the Association of Pool and Spa Professionals (APSP). The only special requirements for the Aqua Plus are the salt level and stabilizer. Saturation index The saturation index (Si) relates to the calcium and alkalinity in the water and is an indicator of the pool water "balance". Your water is properly balanced if the Si is 0 ±0.2. If the Si is below -0.2, the water is corrosive and plaster pool walls will be dissolved into the water. If the Si is above +0.2, scaling and staining will occur. Use the chart below to determine the saturation index. Si = pH + Ti + Ci + Ai - 12.1 ºC ºF Ti Calcuim Hardness Ci Total Alkalinity Ai 12 53 .3 75 1.5 75 1.9 100 1.6 100 2.0 16 60 .4 125 1.7 125 2.1 19 66 .5 150 1.8 150 2.2 200 1.9 200 2.3 24 76 .6 250 2.0 250 2.4 29 84 .7 300 2.1 300 2.5 400 2.2 400 2.6 34 94 .8 600 2.4 600 2.8 39 103 .9 800 2.5 800 2.9 How to use: Measure pool pH, temperature, calcium hardness, and total alkalinity. Use the chart above to determine Ti, Ci,and Ai from your measurements. Insert values of pH, Ti, Ci and Ai into the above equation. If Si equals .2 or more, scaling and staining may occur. If Si equals -.2 or less corrosion or irritation may occur. -.2 0 .2 CORROSIVE SCALING OK 26
