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.
