3.4 Management of the numeric codes for accessing levels 2 and 3
- Access to level 3 is direct for anyone with a PC running the program needed to communicate with Xtraconnect 2 and who connects to the
board.
- Level 2 and level 3 access codes may be obtained only from CIAT Service technicians. Please contact your local CIAT Service office.
3.5 Classification of the menus and their functions
Level 1:
● Menu: Setpoint, Unit status, Measured values, Adjustment parameters, Reading parameters, Fault memory, Programming, Communication
and Access level selection.
● Function: all functions accessible via the console: On/Off, Reset (via the fault memory menu), Heating/Cooling selection, Setpoint 1/2
selection.
Level 2:
● Menu: all level 1 menus + test mode and master/slave mode.
Level 3:
● Menu: all level 2 menus and machine parameters.
IMPORTANT: all the controller parameters are available via the reading parameters menu in read-only mode regardless of the access level
(even level 1). The list of parameters starts at P1 and ends at P811.
4 LIST OF PARAMETERS
Access level: 1 = Access to USER parameters (level 1 parameters only)
2 = Access to viewable and editable parameters (levels 1 and 2). The numeric code is
EDITABLE.
3 = Access to CIAT T
ECHNICIAN parameters (levels 1, 2 and 3). The numeric code is uneditable.
