The HU 9 indoor unit represents a compact and efficient solution for systems without domestic hot water productionor with hot water tanks larger than 200 liters. It is an ideal choice for new buildings and renovation projects where easy installation, space efficiency, and high functionality are key requirements.

Thanks to its integrated hydraulic components — including a 9 kW electric flow heater, 8-liter expansion vessel, three-way valve, and automatic air vent — the HU 9 delivers maximum operational efficiency and reliability. All piping and components are fully insulated against condensation, making the unit suitable for cooling operation without the need for additional insulation.

The control system enables direct management of up to two heating circuits (one direct and one mixed) as well as a cooling circuit, without requiring any additional accessories. Weather-compensated control for both heating and cooling, along with a weekly scheduling program, comes as standard to ensure automated and efficient operation.

The HU 9 is equipped with a 7” touchscreen display featuring a clear and user-friendly menu, allowing convenient adjustment of all parameters as well as monitoring of energy consumption and generated energy. With Wi-Fi connectivity, the system can be easily controlled remotely via a smartphone or tablet.

Installation is quick and straightforward — the unit is wall-mounted and supplied with complete installation accessories. Its modern, clean-line design fits seamlessly into contemporary technical rooms and matches the aesthetics of modern household appliances.

The HU 9 indoor unit therefore represents a reliable, quiet, and intelligent solution for efficient heating and cooling control in your home.
