AVERAGE
DISPLAY AVG
The DISPLAY AVG item selects the display’s averaging
period. The display averaging period is the length of time the
room pressure has been averaged before being displayed.
The DISPLAY AVG item value may be set between 0.75 and
40 seconds. The higher the averaging value, the more stable
the display.
0.75, 1, 2, 3, 5,

DUCT AREA
DUCT AREA
The DUCT AREA
item is used to input the duct size. The
duct size is needed to compute the flow out of the room. This
item requires a TSI flow station to be mounted in the duct.
When a duct area if programmed, the display will
automatically scroll the actual flow as part of the display
sequence. If a zero value is entered, the flow value will not
scroll on the display.
If the DIM displays English units, area must be entered in
square feet. If metric units are displayed area must be
entered in square meters.
0 to 10 square
feet
(0 to 0.9500
square meters)
The DIM does
not compute
area. The area
must be first
calculated and
then entered into
the unit.

TYPE
FLO STA TYPE
The FLO STA TYPE item is used to select the input signal for
the flow station. PRESSURE is selected when TSI flow
stations with pressure transducers are installed. LINEAR is
selected when a linear output flow station is installed (0-5
VDC): Typically a thermal anemometer based flow station.
