You can program your control unit to take advantage of off-peak utility rates, customize schedules, lower water temperatures to save costs, raise the temperature during peak times and much more. OnCommand is a welcomed replacement for outdated time clocks and a great fit for those not needing to add a subpanel to their pool pad. Introducing Aqua Solar® ControlsHayward offers a complete selection of solar controllers that help you maintain the perfect water temperature, without using your heater. All Aqua Solar controllers automatically divert the water flowing between your pool’s filter and heater and route it through solar thermal collectors. There, the water is heated to a set temperature and circulated back into the pool or spa. Pool owners can even maintain their pool and spa at different temperatures. Aqua Solar can also cool a pool and spa. If water is higher than the set temperature, and the temperature in the solar collectors is at least 8° cooler than the pool water, Aqua Solar automatically circulates cooler water into the pool or spa. An Aqua Solar System can pay for itself in as little as three years.OnCommand offers:• Affordable automation of solar controls• Automated pool, spa and other backyard functions• Pool and spa light dimming • Intuitive programming, easy to read display• Automated schedules for off-peak electrical rates• Optional remote control• Up to 70% energy savings controlling a two- or variable-speed pump• 3-year limited warranty
