Reversible brine-to-water heat pump for indoor installation.

  SG Ready

Heat pump for heating and cooling with integrated regulation installed indoors. Variable connection options for brine and heating connections on the back board of the casing. A sound-optimised metal casing and the integrated solid-borne sound insulation with free-swinging compressor base plate make direct connection with the heating system possible. High coefficients of performance (COP) through electronic expansion valve and electronic pump control depending on the temperature spread in the brine and generator circuit. Optimised heating and cooling operation via an internal hydraulic four-way reversing valve which is activated by the controller. Sensor monitoring of the refrigeration circuit for a high degree of operational safety and integrated thermal energy metering (display of the calculated quantity of thermal energy for heating, domestic hot water and swimming pool water preparation). FWO function for more efficient domestic hot water preparation with increased domestic hot water temperatures and volumes of water to be drawn through optimised tank charging.
Universal design with two compressors for output regulation when operating at partial load, optional domestic hot water preparation and flexible expansion options for:

  • Bivalent or bivalent-renewable operating mode
  • Distribution systems with unmixed and mixed heating circuits
  • Use of load-variable tariffs (SG Ready)
Soft starter, flow and return sensors for the brine and heating circuit integrated. Dirt trap for brine circuit, external sensor (standard NTC-2), circulating pumps for brine and heat generator circuit in the scope of supply (observe the free compression). Brine package SZB must be ordered separately. (Spectrum of efficiency classes A+++ to D)
