Application • This air source heat pump with output-dependent control and inverter technology is designed as a compact mono block appliance for outdoor installation. It delivers the required heating output, ensures a reliable supply of domestic hot water and can be used for efficient cooling through circuit reversal. • A flow temperature of up to 75 °C is available for heating mode and DHW heating. Protection against legionella is ensured without the need for an electric auxiliary heater. • The heat pump can also be used to heat older buildings via radiators, as a flow temperature of 55 °C can still be achieved even when there is a heavy frost (-25 °C outside temperature).
