Heating heat pump for indoor installation with integrated heat pump manager WPM Econ5Plus with touch display. Sound-optimized by slow-running EC-3D radial fan, encapsulated compressor chamber and freely swinging compressor base plate for structure-borne sound decoupling. High coefficient of performance (COP) thanks to high-performance evaporator, electronic expansion valve and electronic control of the volume flows. Increase in system efficiency possible through intelligent room temperature control (Smart RTC). Maximum operational reliability through sensor monitoring of the cooling circuit with self-optimizing defrosting. Integrated heat quantity meter to display the calculated heat quantity for heating and hot water preparation on the heat pump manager. The integrated air duct with 90° deflection enables direct corner installation without air ducts or wall installation with air ducts on the blow-out side. Compact design with optional hot water preparation and integrated components for direct connection of an unmixed heating circuit (cannot be used for bivalent systems): Expansion vessel (24 l) High-efficiency heating circulation pump (note free pressure) Overflow valve and safety assembly with pressure gauge Buffer tank 50 l with integrated 2 kW heating element At an outside temperature of -10 °C, a maximum flow temperature of 56 °C can be achieved. Flow and return sensors integrated Outside sensor (standard NTC-2) included in delivery. Dirt trap and flow switch integrated. Heat pump structured white (similar to RAL 9003). Installation option for a switchable pipe heater (special accessory), which can be used for hot water reheating up to 60 °C and as a reserve for heating operation.
