9.3 Climatic curves
The climate related curves can be selected in the user interface. Once the curve is selected, the target water flow temperature in each mode is calculated by the
curve.
It’s possible to select curves even double zone function is enabled.
The relationship between outdoor temperature (T4/°C) and the target water temperature(T1S/°C) is described in the tables and pictures.
9.3.1 Temperature curves for heating mode and ECO heating mode
User terminals type (to set up on service menu Cool and heat mode setting).
Based on the type of user terminal selected the climatic curves set is limited, refer to the below table:
