6.6 Accessing and setting parameters
The confi guration parameters can be used to set and control humidifi er
functions and status.
From the main screen press:
•
ENTER for 2 seconds,
•
enter the password 77 using UP or DOWN,
•
ENTER to confi rm and access the list of parameters,
•
UP or DOWN to scroll the list,
•
ENTER to select a parameter (display: 'set'),
•
UP to modify (increase) the value of the parameter. To scroll faster press
DOWN together,
•
DOWN to modify (decrease) the value of the parameter. To scroll faster
press UP together,
•
ENTER to save the new value and return to the list of parameters, or ESC
to return to the list without saving the value,
Press ESC to return to the main screen.
To access and set the following parameters, see chapters 6 and 12.
7.1 Basic parameters
Parameter
A0
Operating mode
0 = On/Off mode from auxiliary card probe input

board. Parameter A2 is not used
A1
Unit of measure 0 = Celsius ; 1= Fahrenheit
A2
Type of external sensor (optional card) (0 = On/Off ; 1 = 0-10V; 2 = 2-10V; 3 = 0-20 mA; 4 = 4-20 mA)
P0

P1
Humidity control hysteresis
P2
Low humidity alarm threshold
P3
High humidity alarm threshold
(1) To change the value from the terminal it is necessary set all related dipswitch to Off . To again use the value given by the dipswitch it is necessary set one of the dipswitch to On and
power off . At the next reboot the control will use again the values set by the dipswitch.
(*) after 999 the display shows
(**) the default is equal to 0 (zero), for humidifi ers without auxiliary card and without humidity/temperature probe.

CONFIGURATION PARAMETERS
to indicate the 1000s (the three digits are displayed with a dot at the top between the fi rst and second digit).
6.7 Parameters: Recall default values
The default values of the parameters can be recalled at any time from the
main screen.
From the main screen press:
•

•
enter the password 50 using UP or DOWN and press ENTER,
•
The message dEF fl ashes: to recall the default values press ENTER, or
ESC to exit.
