Displayed is the current flow temperature setpoint which is composed of the following
variables:
•
Flow temperature setpoint in function of the composite outside temperature and the
heating curve
•
Position of the setting knob for room temperature readjustments
•
Parallel displacement of heating curve (setting on operating line 72)
With demand-compensated control (plant types 4, 5 and 6), the display shows --- .
