10    Climate Related Curves 
  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 outdoor ambient temperature (T4) and leaving water set temperature (T1s) is described as in 
Figure 3-9.2, Figure 3-9.3, Figure 3-9.4 and Figure 3-9.5. 
 
The automatic setting curves are the ninth curve for cooling and heating mode, the ninth curve can be set as in Figure 
3-9.6 and Figure 3-9.7.

Leaving water set temperature (⁰C ) 
Outdoor ambient temperature (⁰C ) 
Notes: 
1.  It only has the curves of the low temperature setting for heating, if the low temperature is set for heating. 
2.  Curve 4 is default in low temperature heating mode and curve 6 is default in ECO mode.
