Appendix
- Dialogues and additional information
  - Wastewater lifting unit
  - Design options (waste water)
    Drawing-specific settings relating to your calculation are set in the Design options dialogue.
  - Design options (heating)
    Drawing-specific settings relating to your calculation are set in the Design options dialogue.
  - Design options (drinking water)
    Drawing-specific settings relating to your calculation are set in the Design options dialogue.
  - Construction stages
    You can divide a drawing into construction stages so that you can later create a material extract according to construction stages.
  - Component properties
    In the Edit and Calculate work perspective, your selection in the drawing is highlighted in colour. Section properties and component properties can be displayed and edited differently from the global project settings.
  - Component filter
    The component filter allows you to quickly filter the selected components in the drawing.
  - Drainage areas
    The Drainage areas window in the Drainage section is divided into two tabs.
  - Find function
    CALHYDRA has a parameterised search function that supports you when searching for drawn sections and components in the drawing and when selecting products.
  - Hydraulics report
    With the preview of the calculation output, CALHYDRA supports you in customising the calculation output.
  - Mass extract
    With the preview of the mass statement, CALHYDRA supports you in customising the printout of the masses.
  - Material editor
    With the material editor, CALHYDRA supports you with convenient and fast determination of your dimensions.

DHW heater

The DHW heater dialogue shows the settings of the DHW heater or the cold water cooler.

The dialogue appears after double-clicking on the DHW heater or cold water cooler icon in the Pipe network simulation window or by clicking on the DHW or CHP button in the Dashboard (simulation) window.

Note:

If you call up this dialogue after carrying out thermal disinfection, the fields cannot be edited.

Change the name of the DHW heater or cold water cooler.
Change the temperature of the DHW heater or cold water cooler.
Change the maximum temperature difference of the circulation pipe in K.
