4.2. AREA WIZARD [AREA WIZ]
The area of -U and -B probe types generally cannot be determined until the probes are installed. The factory
default output is in velocity, FPM [m/s]. In some cases, the area of other probe types does not equal the area
based on the original order size. The area is required when volumetric airflow, CFM [L/s], is desired. The
area(s) can be entered manually by modifying the area parameter(s) via the SETTINGS menu or the area of
each location can be entered using the AREA WIZARD (AREA WIZ) which is accessed via the TOOLS menu.
AREA WIZ (located in the TOOLS menu)
Use ↑↓ buttons to modify, {ENT} to accept and move to next prompt, {ESC} to move to previous prompt.
If the LOCK is enabled, pressing enter will indicate "CONFIG LOCKED" and this tool will not be available.
Navigate entire menu to step 7 to save settings. Press {ESC} at any time to exit without saving changes.
PROMPT RESPONSE DESCRIPTION
Note: This prompt will only be visible on 2 location devices. Single location devices start at prompt
#2.
The duct or opening is square or rectangular.
The duct or opening is a flat oval.
The duct or opening is round.
The free area duct or opening diameter, in inches [mm]. Value cannot be {null}.
The free area duct or opening width, in inches [mm]. Value cannot be {null}.
The free area duct or opening height, in inches [mm]. Value cannot be {null}.
Displays calculated AREA. ENT to move to next step.
Note: Dual location devices will indicate AREA1 or AREA2 in lieu of AREA.
Save area to AREA parameter and return to normal operation.
Do not save AREA parameter and return to normal operation.
4.3. FAN AREA WIZARD [FAN WIZ]
The area of fan inlet (-F) probe types cannot be determined until the probes are installed. The factory default
output is in velocity, FPM [m/s]. The area is required when volumetric airflow, CFM [L/s], is desired. The area
can be entered manually by modifying the area parameter or the area of each fan can be entered using the
FAN AREA SETUP WIZARD (FAN WIZ) accessed via the TOOLS menu.
The displayed units of measure of transmitters with the -F probe type default to FPM [m/s] since the factory
default setting for area is {null} (no value). The displayed units of measure are automatically changed to CFM
[L/s] when setup wizard changes are saved. The analog output units of measure, if applicable, remain at the
factory default value of FPM [L/s].
4.3.1. Fan Arrays
Individual fan areas are used when the airflow of individual fans in a fan array is desired. Individual fan
airflow rates are available via network variables and allow the advanced fan alarm capabilities of transmitter
to be used. Once entered, individual fan areas can be modified by rerunning the setup wizard or manually via
the SETTINGS menu.
Use the default output unit of measure and scaling of FPM [m/s] to determine CFM [L/s] with your
B.A.S. Simply multiply the default full-scale velocity reading by the total area to determine the full-
scale CFM [L/s] for the B.A.S.
