50/51The RCD system, the digital scroll technology <strong>and</strong> theelectronic bi-flow expansion valve guarantee the highestlevel of efficiency at every operating point.Take advantage of these benefits:Vitocal 300-A for external installation• Reversible <strong>air</strong> source <strong>heat</strong> pump for <strong>heat</strong>ing <strong>and</strong> cooling, for installationinside <strong>and</strong> outside• Variable output control from 3.0 to 9.0 kW• Low operating costs through high coefficients of performance: COP to EN14511: 3.9 (<strong>air</strong> 2 °C/water 35 °C); 4.4 (<strong>air</strong> 7 °C/water 35 °C)• Maximum flow temperature up to 60 °C at 6 °C outside temperature• High efficiency all year round at any operating point <strong>and</strong> therefore lowconsumption costs through the innovative RCD (Refrigerant Cycle Diagnostic)system, <strong>with</strong> an electronic bi-flow expansion valve (EEV)• Low operating noise through radial fan, sound-optimised appliance design <strong>and</strong>night operation <strong>with</strong> reduced fan speed• Easy-to-operate Vitotronic 200 <strong>heat</strong> pump control unit <strong>with</strong> TeleControl <strong>and</strong>remote monitoring for connection to the Vitocom 100, 200 or 300, plus cascadefunction for up to five <strong>heat</strong> pumps• Integral high efficiency pump for the <strong>heat</strong>ing circuit <strong>with</strong> the Vitocal 300-A(internal installation)• Efficient defrosting through circuit reversal• With integral energy statement• Particularly quiet in "silent version"• Active cooling mode possible through reversible refrigerant circuitFor specification, see page 77
