7. CONFIGURATION PARAMETERS
7.1 Accessing and setting the parameters
The con guration parameters are used to select and control the functions
and the status of the humidi er.
From the main screen press:
ENTER for 2 seconds,
•
enter the password 77 using UP or DOWN,•
ENTER to con rm and access the list of parameters,•
UP or DOWN to scroll the list cyclically,•
ENTER to select a parameter (display: ‘set’),•
UP to modify (increase) the value of the parameter. To scroll the values •
faster press UP together with DOWN,
DOWN to modify (decrease) the value of the parameter. To scroll the •
values faster press DOWN together with UP,
ENTER to save the new value and return to the list of parameters, or ESC
•
to return to the list without saving the new value,
Press ESC to return to the main screen.
