Climatic Curves; Temperature Curves For Heating Mode And Eco Heating Mode; Climatic Curve 9 In Heating Mode Settable By The User - Ferroli OMNIA ST 3.2 Manual De Instalación, Uso Y Mantenimiento

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 setup 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:
