# Code
[A.2.1.7] [C-07] Unit control method:
▪ 0 (LWT control): Unit operation is
decided based on the leaving water
temperature regardless the actual
room
demand of the room. This is applicable
for both temperature zones.
▪ 1 (Ext RT control): Unit operation is
decided by the external thermostat or
equivalent (e.g. heat pump convector).
This is applicable for both temperature
zones.
▪ 2 (RT control): Unit operation for the
main temperature zone is decided
based on the ambient temperature of
the user interface. The additional
temperature zone is controlled by the
external thermostat.
[A.2.1.B] N/A Only if there are 2 user interfaces (1
installed in the room, 1 installed at the
indoor unit):
▪ a: At unit
▪ b: In room as room thermostat
▪ c: Remote controller of the heat pump
convectors
User interface location:
▪ At unit: the other user interface is
automatically set to In room and if RT
control is selected act as room
thermostat.
▪ In room (default): the other user
interface is automatically set to At unit
and if RT control is selected to act as
room thermostat. Controlling the main
zone.

# Code
[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: This unit is
designed for 2 leaving water temperature
zones. Do NOT change this setting.
▪ 0 (1 LWT zone): N/A.
▪ 1 (2 LWT zones)(default): 2 leaving
water temperature zones. The zone
with
temperature is called the main leaving
water temperature zone. The zone
with
temperature is called the additional
leaving water temperature zone. In
practice,
temperature
underfloor heating and the additional
water temperature zone consists of
radiators or heat pump convectors.
▪ a: Add LWT zone
▪ b: Main LWT zone
# Code
[A.2.1.9] [F-0D] When the space heating control is OFF
by the user interface, the pump is always
OFF. When the space heating control is
On, you can select the desired pump
operation mode (only applicable during
space heating). This is applicable for
both temperature zones.
Pump operation mode:
▪ 0 (Continuous): Continuous pump
operation, regardless of thermo ON or
OFF condition. Remark: continuous
pump operation requires more energy
than
operation.
