Intermediate return piece

An intermediate return piece can be provided for
installing the safety expansion line and for height
compensation of the intermediate flow piece ( Tab 34,
page 72). A further temperature sensor can be
connected to this. A fully functioning intermediate return
piece is already integrated into the return temperature
raising set ( page 76).
