The climate related curves can be selected in the user interface, MENU
> PRESET TEMPERATURE > WEATHER TEMP. SET.
The curves for heating mode and ECO heating mode are the same but
the default curve is curve 4 in heating mode, while in ECO mode, the
default curve is curve 6.
The default curves for cooling mode is curve 4. Once the curve is
selected, the leaving water set temperature (T1s) is determined by the
outdoor temperature.
In each mode, each curve from the eight curves in the user interface
can be selected.
The relationship between outside temperature (T4) and leaving water
set temperature (T1s) is described as in Figure A, Figure B, Figure C
and Figure D
The automatic setting curves are the ninth curve for cooling and heating mode, the ninth curve can be set
as in Figure E and Figure F
Low temperature curves for heating mode1
Notes:
1 Selectable when the low temperature for heating is set.
2 Curve 4 is default in low temperature heating mode and curve 6 is default in ECO mode.
