HEATING CURVES
Under HEATING CURVES, you can adjust the respective heating
curves for heating circuits 1 and 2. It is very important that the
correct heating curve is selected to ensure a constant room tem-
perature.
Note
Your contractor will have set up a building and sys-
tem-specific optimum heating curve for every heating
circuit. For heating circuit 1 this heating curve relates to
the heat pump return temperature, for heating circuit 2
it relates to the mixer flow temperature.
When the heating curve is displayed on the heat pump manager,
the calculated set return or flow temperature, subject to the out-
side temperature and the set room temperature, will be shown
at the top of the display.
As soon as a temperature has been preselected via the fixed tem-
perature parameter at control level 3, heating curve 1 will be
hidden. If this is the case the display will show FIXED FLOW T with
the relevant temperature.
