# 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.

[A.2.1.9] [F-0D] When the space heating/cooling control
is OFF by the user interface, the pump is

cooling control is On, you can select the
desired pump operation mode (only
applicable during space heating/cooling)
Pump operation mode:
▪ 0 (Continuous): Continuous pump
operation, regardless of thermo ON or
OFF condition. Remark: continuous
pump operation requires more energy
than sample or request pump
operation.

▪ 1 (Sample): The pump is ON when
there is heating or cooling demand as
the leaving water temperature has not
reached the desired temperature yet.
When thermo OFF condition occurs,
the pump runs every 5 minutes to
check the water temperature and
demand heating or cooling if
necessary. Remark: Sample is NOT
available in external room thermostat
control or room thermostat control.
