3.22 Heating curve slope heating circuit 2 (S2)

Constant room temperature in spite of outside temperature variations.
The controller generates the flow temperature setpoint only for heating circuit 2, based
on the selected heating curve.
Setting range
– – : – / 2.5...40.0
By changing the setting, the slope of the heating curve will be increased or decreased.
Entry:
– : – – All functions of heating circuit 2 are deactivated Frost protection for the
building and the plant will not be active (frost protection for the boiler and
d.h.w. remains active).
2.5...40.0 All functions of heating circuit 2 will be activated
Increase: The flow temperature will be raised when the outside temperature drops
Decrease: The flow temperature will be raised less when the outside temperature
drops
This setting also has an effect on the generation of the type of plant displayed on line
53. The switching on and off of the heating circuit through the setting – : – – or a value
changes the plant configuration accordingly.
For detailed information about the heating curve, refer to "Slope of heating curve
heating circuit 1 " (S1).
The flow temperature setpoint determined in this way serves as a setpoint request for
generating the boiler temperature setpoint. Also refer to "generation of boiler
temperature setpoint" in Index.
