curve
Main zone – Cooling [2.6] Main zone > Cooling WD
curve
Additional zone – Heating [3.5] Additional zone > Heating

Additional zone – Cooling [3.6] Additional zone > Cooling
WD curve
2 Change the weather-dependent curve.
There are 2 types of WD curves: slope-offset curve (default), and 2-points
curve. If needed, you can change the type in [2.E] Main zone > WD curve
type. The way to adjust the curve depends on the type.
Slope-offset curve
Slope. When slope is changed, the new
preferred temperature at X1 is
unequally higher than the preferred
temperature at X2.
