Flow Configuration

The flow configuration menu provides access to modify the application 
specific parameters.

NOTE: All transmitters are factory configured for the intended 
application – Changes to the factory configuration should not be 
required. A Factory Set-Up Sheet is provided with each transmitter 
and provides the details for all factory configured parameters.

The 

measurement type

 for all Greenheck Vari-Green applications will be 

selected as ducted. One transmitter accepts up to 32 sensors.

Ducted:

Select the proper duct shape
(Rectangular, Flat Oval or Circular).
Enter the duct dimensions (inches or millimeters).
Area (cross-sectional duct area) is automatically calculated.
Enter the Max Flow (maximum airflow) in CFM or L/s.

Display Configuration

This screen allows the user to set parameters on various lines of the 
display. There are four display lines on the Vari-Green.

Line 1

 - Flow (typical), Velocity or Temperature. 

Line 2

 - Velocity, Flow or None. 

Line 3

 - Temperature, Flow or None. 

Line 4

 - Custom ID or None.

A custom ID can be entered through the Service Menu. It is typically used 
to describe the transmitter location in the building.

Brightness

 -  Allows the user to set the brightness of the display in real 

time.

Inactivity Timeout

 -  The time period which holds the display in menu 

mode. When the timer expires, the display is 
returned to the main display screen showing the 
process values.

Analog Output Configuration

The Vari-Green transmitter is equipped with dual analog outputs. The 
Analog Output Configuration menu configures the analog output type, 
parameter and filter. 

Output Type

: 4-20 mADC, 0-5 VDC or 0-10 VDC 

Output 1 and 2:

 Flow, Velocity or Temperature

The 

Filter

 has a minimum setting of 0 to a maximum setting of 10. To 

disable the Filter, select Off.

Display Average Filter

The Display Averaging Filter filters the data shown on the display. It affects 
all elements of the display. The Filter has 1-10 settings - 1 is the lightest 
filter, and 10 represents the heaviest filter. It also has an ‘Off’ setting.
