Forcing Inputs and Outputs —
may be forced both from the CCN and directly at the local
display. This can be useful during diagnostic testing and also
during operation, typically as part of an advanced third party
control scheme. Please see Appendix A and B.
NOTE: In the case of a power reset, any force levels in effect
at the time of the power reset will be cleared.
CONTROL LEVEL FORCING — If any of the following
points are forced with a priority level of 7 (consult CCN litera-
ture for a description of priority levels), the software clears the
force from the point if it has not been written to or forced again
within the timeout periods defined below:

user important information about the unit. The Run Status table
can be used to troubleshoot problems and to help determine
how and why the unit is operating.
AUTO VIEW OF RUN STATUS — The Auto View of Run
Status display table provides the most important unit informa-
tion. The HVAC Mode (Run Status
forms the user what HVAC mode the unit is currently in. Refer
to the Modes section on page 40 for information on HVAC
modes. The occupied status, unit temperatures, unit set points,
and stage information can also be shown. See Table 78.
