The Duetto is the world's smallest dual-sensor ATO, as well
as the easiest to install. Our proprietary dual-optical sensor
utilizes the bottom sensor for normal top-off operation. The
top sensor, along with our intelligent QST programming, are
used for overflow protection.
Not only will the Duetto ATO maintain a super-precise water
level in your sump, it will also keep your sump safe from
overflows caused by over filling.
The Duetto ATO is plug-and-play and all parts are included
for most installations.No programming or adjustments are
required.
Thank you for choosing XP Aqua!
Thank you for purchasing the XP Aqua Duetto ATO.
These instructions will guide you through the installation and
explain how the system will operate.
