Keypad inactivity timeout
(minutes)
End the user session, turn off the backlight, and display the
standby screen after this period of inactivity.
Keypad user-level
password
Numeric password user must enter to access system
through BACview.
Module Clock
Clock Fail Date and Time
Date and time control program uses when controller's real-
time clock is invalid.
TIP
Use an occupied date and time (such as a Tuesday at
10 a.m.) so the equipment does not operate in unoccupied
mode if the controller loses power during occupancy.
Time Synch Sensitivity
(seconds)
When the controller receives a time synch, if the difference
between the controller's time and the time synch's time is
greater than this field's value, the controller's time is
immediately changed. If the difference is less than this
field's value, the controller's time is slowly adjusted until the
time is correct.
BACnet COV Throttling
Enable COV Throttling
Under normal circumstances, COV Throttling should be
enabled to prevent excessive network traffic if an object's
COV Increment is set too low. See EXCEPTION below.
When enabled, if an object generates excessive COV
broadcasts (5 updates in 3 seconds), the driver
automatically throttles the broadcasts to 1 per second.
Also, if the object's value updates excessively for 30
seconds, an alarm is sent to WebCTRL listing all objects
that are updating excessively. A Return-to-normal alarm is
sent only after all objects have stopped updating
excessively.
EXCEPTION: In rare circumstances, such as process
control, a subscribing object may require COV updates more
frequently than once per second. For these situations, clear
this checkbox, but make sure that your network can support
the increased traffic. You will also need to disable the
Excessive COV
alarms under the driver's
Common Alarms
.
