The WXE20I-WiFi is an advanced weather-compensated control for efficiently managing heating, cooling, and domestic hot water in family homes.
With built-in WiFi, it allows for convenient control via an app, supports up to 52 hydraulic schemes, two heating circuits, a heat pump, a boiler, a buffer tank, and a solar system.
Timer programs, the BOOST function, protective features, and easy start-up provide increased comfort, safety, and energy efficiency.
