FAQ

What is Test & Balance used for?

Test & Balance is used to manipulate controllers associated with an air source, excluding the air source itself and heating/cooling equipment like chillers and boilers.

What is Test & Balance?

The Test & Balance application lets you:

Calibrate airflow sensors in Open VAV/VVT zone controllers, TruVu™ VAV/VVT zone controllers, or any TruVu™ controllers that are using the Airflow microblock
Calibrate the static pressure in an Open VVT bypass controller or TruVu™ VVT bypass controller
Commission air terminals
Override reheat and terminal fans to test and balance related systems
- NOTE You use Test & Balance to manipulate the controllers associated with an air source, but not the air source itself or heating and cooling equipment such as chillers and boilers.

Calibrating air terminals

To calibrate air terminals, do the following:

Step 1 : Connect to the controller or sensor through the Rnet port (page 3) or Connect to the controller through the Service port (page 4) You have the option to balance just the zone you are connected to or all zones for the related air source.
Step 2 : Calibrate airflow (page 7) or calibrate static pressure (page 7). Changes you make in Test & Balance are saved directly to the controller and take effect immediately.
Step 3 : Upload calibration values to the i-Vu® application (page 11).
Step 4 : Run a report in Test & Balance (page 12) (optional).

Step 1 : Connect to the controller or sensor

In this step, you connect a laptop running Test & Balance to the

Rnet-enabled sensor communicating with the zone or bypass controller
Rnet port of Open or TruVu™ VAV/VVT zone or VVT bypass controllers
Service port of TruVu™ VAV/VVT zone or VVT bypass controllers
- NOTE Multiple operators connected to different Rnet or Service port networks can use Test & Balance simultaneously. If they issue different commands for the same equipment, the last command received overrides previous commands.
