Heat pump for heating and cooling with inverter control for outdoor installation with wall-mounted heat pump manager WPM Touch with touch display. Sound-optimized through flow-optimized air flow with encapsulated compressor chamber, axial fan for naturally quiet air noise and freely swinging compressor base plate for structure-borne sound decoupling. High coefficient of performance (COP) through high-performance evaporator, electronic expansion valve, EC fan for adjusting the air volume flow, self-optimizing power control and natural refrigerant R290. Maximum operational reliability through sensor monitoring of the refrigeration circuit with self-optimizing defrosting, additional safety is offered by the sophisticated safety concept with minimal distances (1 meter) for the use of the natural refrigerant R290. The integrated flow sensor and the heat quantity meter for displaying the calculated heat quantity for heating and hot water preparation on the heat pump manager round off the topic of operational reliability. Simple and quick installation thanks to installation close to the wall with a minimum wall clearance of 0.3 m on the intake side, a housing concept optimized for outdoor installation and the option of connecting the heat pump from below and behind. Universal design with flexible expansion options for: bivalent or bivalent regenerative operation unmixed and mixed heating/cooling circuit room temperature control via Smart-RTC (special accessory) use of load-variable tariffs (SG Ready) At an outside temperature of -10 °C, a maximum flow temperature of 65 °C can be achieved. For silent cooling via surface heating/cooling systems, the room temperature controller with humidity sensor (RTM Econ) and a mixed heating circuit are required to regulate the flow temperature depending on the air temperature and humidity of a reference room. Dirt trap and sensor flow measurement to ensure the minimum heating water throughput integrated. Flow and return flow
