Communication Status

Diagnostic Reporting is not applicable to the TV-VVTZC-E2.

Protocol Status shows the status of the protocols currently running on the TV-VVTZC-E2.

Standalone Controller Detection

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.

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.

Installation and Start-up Guide

Flow reading is being generated from default pressure table. Flow sensor always reads

absolute.

Flow reading is generated from Airflow Control microblock readings section. Flow sensor

indicates negative values if flow is reversed through the VAV box.

Refers to the tube connections. If tubes are switched after calibration process is

complete, the calibration process has to re-run to clear settings.
