User screen
Figure 53: User screen
This screen allows definition of custom User ID’s and matching passwords. This allows the building
administrator to assign custom passwords to those who are authorized to maintain the chiller.
Each custom user value is not linked to a specific button. Instead, the Change User Attributes
button is pressed which enables the cursor arrows which are used to highlight the custom user
parameter the user wishes to modify. At this point the Enter button is pressed and the value may
be entered.
