Aqua Plus simplifies and enhances pool and spa ownership by combining control and electronic chlorination into one easy-to-install, easy-to-operate package. With Aqua Plus, programming essential functions for maximum performance, effectiveness and cost-efficiency is a snap. It lets pool owners set filtration and temperature schedules: steady all week, increasing dusing busy weekends, or cutting back on weekdays when activity is limited. They can even control other backyard features, including patio and landscape lighting, water features and firepits. Aqua Plus comes equipped with 4 relays and 3 valve outputs, manages 1 traditional heater and 1 solar heater and is also equipped with a salt chlorination cell for pools up to 40,000 gallons.
