There are 2 leaving water temperature zones:
▪
The zone with the lowest leaving water temperature (in heating) is called the
main leaving water temperature zone.
▪
The zone with the highest leaving water temperature (in heating) is called the

In practice, the main leaving water temperature zone consists of the
higher load heat emitters and a mixing station is installed to achieve the desired
leaving water temperature.
