  • Page 4: Safety Notes

    • The operating element of the SolvisControl system controller must be protected from direct sunlight. Solvis heating systems use state-of-the-art technology and meet all relevant safety requirements. They are designed with particular emphasis on safety. But improper operation may result in hazards or damages.

  • Page 5: Information About The System

    Information about the system 2 Information about the System Congratulations on your purchase of the SolvisDirekt system. The main feature of this system is the central, hygienic and economic water heating. General functional description (Figure on right) The hot water station WWS-36 as part of the SolvisDirekt system consists of components (1) and (2).
  • Page 6 The SolvisStrato stratified buffer tank was designed espe- cially for use in solar systems. It is the core element of your heating system. In the Low-Flow System from Solvis, your SolvisStrato can be used with all collector surfaces up to 40 m².
  • Page 7 Information about the system 2.2 Hot water station WWS-xx The hot water station WWS-xx is as described in section 2 the core element of the SolvisDirekt system. It includes all components required for heating drinking water to the desired temperature. The hot water station consists of a plate heat exchanger (PHE) as well as a buffer charging station and it has an integrated volume flow encoder to control the heating of...
