[C-07]
Unit control method:
Q
0 (LWT control): Unit operation is
decided based on the leaving water
temperature regardless the actual
room temperature and/or heating or
cooling demand of the room.
Q
1 (Ext RT control): Unit operation is
decided by the external thermostat
or equivalent (e.g. heat pump
convector).
Q
2 (RT control): Unit operation is
decided based on the ambient
temperature of the user interface.
[A.2.1.B]
N/A
Only if there are 2 user interfaces (1
installed in the room, 1 installed at the
indoor unit):
User interface location:
Q
At unit: the other user interface is
automatically set to In room and if
RT control is selected act as room
thermostat.

[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:
Q
0 (1 LWT zone)(default): Only 1
leaving water temperature zone.
This zone is called the main leaving
water temperature zone.
Q
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.
