Z400iQ is designed to extend your swimming season while blending quietly into its surroundings. It heats or cools the water as the weather changes, keeping the pool at a comfortable temperature for longer without drawing attention to itself. ON/OFF technology pairs a two-speed fan with two operating modes, Standard and Silence, so you can choose quieter running when the garden calls for calm. A titanium water exchanger keeps the pump compatible with salt-treated pools, while a heating priority mode and automatic defrosting help it run dependably with little intervention. The polypropylene and galvanized steel body is finished to sit comfortably in an outdoor space. Embedded Wi-Fi connectivity and a free mobile app let you control the temperature from anywhere, and the LCD display keeps everyday adjustments clear. Suited to pools of up to 145 m³ and made in Italy, Z400iQ combines efficient heating with a compact, discreet presence.
