Setpoint of the cascade flow temperature

•
Indication of setpoint of the cascade flow temperature
•
Better overview of the plant's operating state
The setpoint of the cascade flow temperature will automatically be displayed on this
line.
1. Press the operating line selection buttons to select line 66.
2. No setting can be made with the + / - buttons.
Display
0...140
The setpoint can only be displayed, but not changed. The function helps better
understand the control sequences taking place in the controller.
The setpoint displayed is generated based on the different heat demand signals
received from the system. These are:
•
Demand for heat from the controller's internal heating circuits based on the outside
temperature
•
Demand for heat from the external heating circuits (system) based on the outside
temperature
•
Demand for heat for d.h.w. (from inside the controller or externally)
•
Demand for heat via contact H1
•
Demand for heat resulting from protective functions (e.g. frost protection for the
plant)
•
Demand for heat by pressing the button for manual operation
The highest of the setpoints received is shown on the display as the setpoint of the
cascade flow temperature.
The display shows "---" if one of the following points applies:
•
There is no demand for heat
• The controller has been defined as a cascade controller (device address > 1)
•
Sensor B10 has not been detected or connected
