Air-to-water heat pumps for indoor installation with external temperature controlled WPM 2006 Plus heat pump manager and two compressors for output reduction when operating at partial load. The air is drawn in via the heat pump installed directly in front of the wall. The air circuit on the air outlet side is established via air ducts. Sound-optimised through low-noise, low-speed axial fan and encapsulated compressor housing; energy-efficient defrosting by reverse circulation. High coefficients of performance (COP) through high-performance evaporator and compliance with the requirements of EN 14511 for larger volume flows on the heat consumption side. Universal design with two compressors for modulating operation, optional domestic hot water preparation and flexible expansion options for:
