Security mode
This mode imposes a maximum temperature set point which
is impossible to exceed regardless of the mode in progress.
However, it is still possible to lower the set point at your
discretion. The programming of the Auto and Pre-Prog modes
also respects this maximum temperature set point. Please note
that when the Security mode is activated, it is impossible to
switch from the
mode to the
mode, and conversely.
