The flow balancing view is used to balance a controller that is 

programmed with a standard VAV application. Based on the 

version of the VAV application and its features, the following 

operations can be performed on the view.

• Flow pressure zero calibration

• Two point calibration

• K factor calibration

• Heating coil water flow calibration.

• Pre-requisites

• The controller must be online.

• The controller must be in a commissioned state.

• VAV Zone Terminal Single Duct must be selected as the 

Application Type and Air Balance Supported must be 

selected.

• Select the Reheat Valve Override Supported option to 

calibrate the reheat valve.

• Select the Peripheral Heat Valve Override Supported 

option to calibrate the peripheral heat valve.

To start zero balancing:

Click 

The damper is completely closed. If any flow pressure is 

detected, that value is considered to be the flow pressure 

offset. After the completion of zero balancing, the device 

mode is set to automatic operation.

Right-click ControlProgram and select 

Views > Flow Balancing View. The Flow Balancing View appears on 

the right pane.

You can type the values into the following fields.

Actuator Travel Time The actuator travel time is the time required by the actuator to travel from 0% to 100% open or 100% to 

0% open. This time interval depends on the actuator type and can vary from 0 to 500 seconds.

K Factor

This field allows you to manually change the K factor value from 0 to 10000.

Inlet Area

Displays the area of the duct. Either a standard diameter can be selected or a custom area can be 

entered in this field. The inlet area ranges from 0 to 100 sq.ft.

Measured Flow

Displays the actual air flow when measured by the balancer using an accurate device. This field is 

editable.

Maximum Flow 

Setpoint

This field allows you to set the flow setpoint from 0 to 138850 cfm for maximum flow calibration and k 

factor calibration. The controller seeks stable flow and when it is reached, it allows you to set the 

calibration source value.

Minimum Flow 

Setpoint

This field allows you to set the flow setpoint value from 0 to 138850 cfm. You must set the flow setpoint 

less than the maximum value to obtain minimum flow calibration. The controller seeks stable flow and 

when it is reached, it allows you to set the calibration source value.

Re-heat Valve 

Override

This field allows to override the value of the reheat valve in an application built for the reheat valve. This 

field is visible when the 

Reheat Valve Override Supported feature is selected in the Details View of 

the 

Control Program.

Peripheral Heat 

Valve Override

This field allows to override the value of the peripheral heat valve in an application built for the 

peripheral heat valve. This field is visible when the 

Peripheral Heat Valve Override Supported feature 

is selected in the 

Details View of the Control Program.

Device Mode

Displays the current device mode. This is a non-editable field.

Damper Position

Displays the current damper position. This is a non-editable field.

Sensed Flow

Displays the actual air flow that is measured by a pressure sensor. This field is non-editable.

Flow Pressure

Displays the current flow pressure. This field is non-editable.
