GENERAL INFORMATION
For safety reasons and greater convenience for the operator, the
ECP300 EXPERT
STEPPER
system provides four programming levels; the first is used only for the

programming and setting the general parameters relating to the various operating modes
of the board, the third is used for managing the parameters relating to the electronic

valve.
If you are at one programming level, you cannot directly access another level, but you
