VVT Zone II Controller
Installation and Start-up Guide
This field is checked automatically to allow a user to edit this controller's
schedules from an Equipment Touch's Schedules screen. Uncheck to disable.
Date and time the control program uses when controller's time 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.
When the controller receives a time sync request, if the difference between the
controller's time and the time sync'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.
The maximum number of retries after the initial attempt that a Network
microblock will attempt to communicate with its target device. If unsuccessful, the
point will transition to an idle state for 30 seconds before attempting to
communicate again. Change this field only if directed by Technical Support.
If a microblock uses a wildcard in its address, this timer determines how often the
microblock will attempt to find the nearest instance of its target. For example, if
an outside air temperature address uses a wildcard, a VAV application will look for
the outside air temperature on the same network segment or on the nearest
device containing that object.
