Cold water: Sets the ambient temperature for all cold water sections. The default value according to the standard is 10 °C.

Hot water: Sets the ambient temperature for all hot water and circulation sections. The default value according to the standard is 25 °C.

Tip: If you want to assign different ambient temperatures to individual sections, you can do so in the Ambience dialog on the tab Temperature.
