Heat treatment validation temperature
The heat treatment settings are those defined in the (French) decree of 30 November
2015. However, depending on applicable local or national regulations, these settings
can be altered using this menu.
Heat treatment is considered successful when it reaches one of the 3 defined temperature/
duration combinations and maintains this combination to the end of the programmed
time. The phase ends with the flush, if included for a return to standard mode.
