# Code Description
[A.2.1.8] [7-02] The system can supply leaving water to
up to 2 water temperature zones. During
configuration, the number of water zones
must be set.
Number of LWT zones:
▪ 0 (1 LWT zone)(default): Only 1
leaving water temperature zone. This
zone is called the main leaving water
temperature zone.

▪ 1 (2 LWT zones): 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
additional leaving water temperature
zone. 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.
