How to adjust the heating curve (loi d'eau) on a device?

To adjust the heating curve (loi d'eau), which optimizes a heating system by adapting the heating water temperature to the outdoor temperature, follow these steps:

  1. Understand the Principle: The heating curve ensures that the heating water temperature increases as the outdoor temperature drops, and vice versa.
  2. Identify Parameters: Two main parameters are adjusted:
    • Normal: This sets the desired return heating water temperature when the outdoor air temperature is -18 °C.
    • Correction: This adjusts the inclination (slope) of the temperature curve specifically at an outdoor temperature of 15 °C, which is particularly useful during transitional periods.
  3. Adjustment Procedure:
    • Access the 'Heating' menu from the device's base menu.
    • Select the 'Correction' parameter to fine-tune the temperature during transitional weather.
    • Select the 'Normal' parameter to set the maximum heating water temperature corresponding to an outdoor temperature of -18 °C.

It is important to note that these settings might require further adjustments to match comfort preferences and the specific characteristics of an installation.
