AH CL 21a

This inverter-controlled outdoor heat pump is ideal for buildings requiring high water temperatures – whether detached houses and apartment buildings or commercial buildings with underfloor heating or radiators (both new-build and renovation projects). In addition to heating and domestic hot water, the heat pump can also provide active cooling (subject to prior clarification). The heat pump is conveniently operated via the built-in display or the app. Thanks to its sound- and vibration-optimised design, the unit is ultra-quiet. Several units can be interconnected in a cascade if required. The heat pump can be easily integrated into an energy management system, helping to increase the self-consumption of photovoltaic installations. We recommend a LAN connection via the router provided by the building owner.
