The setpoint value for the supply line and the max value of the return line
are shown in brackets. The max value indicates the temperature at which
the compressor is stopped. No values can be changed in this menu.
The present temperatures in the system are shown here. Temperatures are
recorded and stored for 100 minutes so that they may be displayed graph-
ically
If ROOM shows 20°C the heat curve is unaffected. If ROOM shows a higher
