Air-to-water heat pump for indoor installation.

Outstanding performance for large areas.

  • Naturally quiet. Low-noise axial fan. Encapsulated compressor chamber and free swinging compressor base plate for solid-borne sound insulation.
  • Power-regulated. Two compressor settings for optimal adjustment of the heat output to the building consumption.
  • Expansion options. Bivalent or bivalent-renewable operation, distribution systems with mixed and unmixed heating circuits (e.g. underfloor heating and radiators). Even more efficient room temperature control Smart-RTC+.
  • Future-orientated. Use of load-variable tariffs or self-produced PV-electricity possible: SmartGrid Ready. Even more efficient room temperature control Smart-RTC+.
  • Flexible. The integrated air circuit enables corner or wall installation with air ducts at the air intake and the air outlet side.
  • Technical Data.
