You can use the fields on this page with a binary input in your control program to detect when the controller does
not receive a write request from the selected network within the specified amount of time. The input remains OFF
as long as write requests are received, but switches to ON if the controller does not receive a request within the
specified time. The binary input must have the Expander number and Input number set to
99
and the I/O Type set
to
Special
.
Flow Calibration Archive
The
Flow Calibration Archive
page shows measured flow and sensor readings that were entered in the i-Vu®
interface Test and Balance or through the stand-alone Airflow Test and Balance Utility.
Flow Sensor Input
Tubes
Not Calibrated
Flow reading is being generated from default pressure table. Flow sensor always reads
absolute.
Calibrated
Flow reading is generated from Airflow Control microblock readings section. Flow sensor
indicates negative values if flow is reversed through the VAV box.
Normal / Reversed
Refers to the tube connections. If tubes are switched after calibration process is
complete, the calibration process has to re-run to clear settings.
