This guide shows how to set up a complete system to automatically monitor and dispense the two major chemicals required to maintain a pool water chemistry, chlorine and Ph reducer. It starts by describing the function of each component then shows how the components are linked together. This is intended as an overview. Detailed installation instructions are provided in the owner's manuals. While this is a Jandy configuration, the concepts described are generic and can be applied to most other systems.
The primary controls for the chemical monitoring and dispensing equipment will be integrated into a Jandy Aqualink RS Power Center. This Power Center is installed outside next to the pool equipment to facilitate servicing of the pool equipment. The Power Center is connected to a Jandy Touch Screen mounted inside the house to control programming and operation of the pool function. A picture of the Jandy Touch Screen is shown here
The Jandy Aqualink RS Power Center is a weather-resistant metal enclosure located near the equipment and in which the Control System is installed. When you purchase a Power Center, you get the metal case, a set of relays and a transformer. The Main Printed Circuit Board (PCB) and service control panel of the Control System will be installed in the Power Center as well. Each Power Center can handle up to 8 features. This system was designed for 16 features so has two interconnected Power Centers.
This pool configuration uses three systems in conjunction with the Aqualink RS Power Center to automatically monitor and disperse chlorine and Ph levels: the Jandy Chemlink C1900, the Jandy Fusion Soft Nature2 System and the Stenner Tank and Pump System.
Jandy Chemlink C1900 monitors sanitizer and pH levels automatically, activating purification systems if water chemistry falls below preset levels. ChemLink enables precision chemical dosing, alleviating the highs and lows caused by organic contaminates and overfeeding. The Chemlink C1900 has two components, the Chemlink Controller, shown here, and the Chemlink Flow Cell shown below.
The Chemlink C1900 Flow Cell is used to monitor pool water chemistry. Water from the pool enters on the left and exits on the right. One part of the cell monitors the chlorine level and another, the Ph level. These readings are passed through the Chemlink C1900 Controller to the Aqualink RS Power Center and Jandy Touch Screen.
The Jandy Fusion Soft Nature 2 system converts salt water to chlorine and dispenses minerals when the Chemlink C1900 system senses low chlorine levels. The Fusion System has two components, a Nature2 Cartridge and an Electrolytic Cell. The Nature2 Cartridge delivers controlled trace amounts of beneficial minerals to help reduce bacteria and maintain an algae free pool. The mineral cartridge also reduces the amount of chlorine your pool requires, which dramatically improves the water quality and extends the life of the Electrolytic Cell. The Electrolytic Cell produces chlorine from a low concentration of salt added to the pool water. The chlorine kills bacteria, oxidizes organic material, and kills algae.
This next few steps show how the components are integrated into the pool control system. The Chemlink C1900 Controller has power and control lines going to the Aqualink RS Power Center and control lines going to the Chemlink C1900 Flow Cell. The Controller also has control lines to the Stenner Pump.
Operationally, water from the input line is sampled by the Chemlink C1900 Flow Cell for both chlorine and Ph level. These readings are collected in the Chemlink C1900 Controller and passed to the Aqualink RS Power Center and Jandy Touch Screen. If the chlorine level is too low, the Aqualink RS Control System will turn on the Jandy Fusion Soft Nature 2 System to generate and dispense chlorine and minerals into the pool water. If the Ph level is higher than the programmed value set in the Touch Screen, the Aqualink RS Control System will instruct the Chemlink C1900 Controller to turn on the Stenner Pump to drawn acid from the tank and inject it into the pool water through the return line.
