Programming level 0 : control
The STATOP 4849 has several security levels (SEL function), to prohibit an unauthorised user access to
the fundamental control parameters.
User security resides in the necessity for the installer to keep the
seconds and at the most 16 seconds during display of the last parameter accessible at a given level to
access the higher level.
Programming level 0 concerns the directly accessible parameters and which are not the subject of
prohibited access.

During Automatic Mode, pressing the
output power in percent, without returning to Manual Mode.
3.5.2
Automatic operation
This is the normal mode of use of the controller.
When setting up for the first time, no parameter is accessible at level 0 of programming, because the
" SEL " parameter has a value 0. Only the setpoint value can be modified, by means of buttons
and on condition that the keyboard has not been locked (" LoCL " parameter, see § 3.7). Go directly to
stage 1 of the following chapter.
Subsequently, you may change the value of the " SEL " parameter so as to access, for this level of
programming (i.e. without protection), some parameters of level 1.
