For some heat pumps, the heating curve values in ViCare app do not match those on the device display. Please note that this is not an error and that your heat pump is working correctly according to the values shown on the display. The cause lies in the different rounding of the temperature values (rounding up vs. rounding down). The maximum temperature deviation can be +/- 1.
You can use the following images to compare the values from the app and HMI as an example:
