Screen Description
Keypad For: All controllers
Navigate to:
System Settings > Keypad
Lets you define:
•
The amount of time (255 min. maximum) of inactivity after which the standby screen
displays and, if applicable, the backlight on a BAC view ® 6 device turns off.
NOTE This time can also be defined in the module driver.
•
The priority level (0-16), that the BAC view ® device uses to write BACnet commandable
properties to a controller.
BACnet Priorities:
0 = Relinquish Default (Writes this as the default value for the controller)
1 = Munual Life Safety (Highest priority)
2 = Automatic Life Safety
3 = Available
4 = Available
5 = Critical Equipment Control
6 = Minimum ON/OFF
8 = Manual Operator
9 = Available
10 = Available
11 = Available
12 = Available
13 = Available
14 = Available
15 = Available
16 = Available (Lowest priority)
NOTE The value that is written from the BAC view ® device is always written to the controller. If a
priority of 1-16 is specified, other BACnet devices must write at a priority equal to or greater
than the priority specified by the BAC view ® device.
EXAMPLE The Heating Setpoint is written to the controller by a BAC view ® device at Priority 9.
Another BACnet device writes the Heating Setpoint to the controller at Priority 16. This value will
NOT overwrite the BAC view ® value since it was written at a lower priority (16) than the
BAC view ® priority (9).
BACnet For: All controllers except i-Vu® Open Router

Lets you view or edit the controller's BACnet Device Instance number. This is a unique number
that is typically autogenerated. However, if you need to use a custom number, set
Autogenerate Device ID to N , then enter your custom BACnet Device Instance number.
