Based on Scheduler
Based on the current room setpoint temperatures
The heating curve, and therefore the supply setpoint temperature, is as standard only
a theoretical value that is exclusively dependent on the outside temperature.
This parameter specifies that, in addition to the theoretical nominal room setpoint
temperature, the actual room setpoint temperature flows into the calculation and the
calculated heating curve is correspondingly lowered in times with low room setpoint
temperatures. The term "nighttime reduction" is also used. In this way during times
with low heat demand in the rooms, the heat provided is reduced to lower the losses
and therefore save energy.
•
Disabled: The heating curve is static and based only on the parameterized
nominal room temperature. There is no dynamic lowering of the heating curve.
•
Based on Scheduler: The heating curve is adjusted dynamically based on a
scheduler. The scheduler switches between the operating modes and the related
room setpoint temperatures. A heating curve is displayed for each operating
mode and the mode activated is marked on the web user interface for the
module. An ASM input socket for connecting an operating mode scheduler is
displayed on activating this function. Which operating modes are used can be
set using the parameters that follow. An ASM input socket is also displayed for
each of these operating modes activated; the related room setpoint temperature
is passed to the module using this input socket.
•
Based on the current room setpoint temperatures: The heating curve is adjusted
dynamically based on the room setpoint temperatures currently active in the
rooms. An ASM input socket configured for the selection of the maximum is
displayed on activating this function. All room setpoint temperatures for the
heating circuit are connected to this object; the module selects the highest room
setpoint temperature as the basis for the calculation.
