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

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.
