DOCUMENT INTRODUCTION
This document describes the TDFi-RT Advanced Thermal Dispersion Fan Inlet Airflow Measuring System’s features and functions. It also
provides guidelines and instructions for setting up and trouble-shooting these devices used in plenum and duct applications.
START-UP
Navigating the Start-Up Menu
After Installation has been verified, apply power to the TDFi-RT Host Monitor. Menu displays will be generated on the Host Monitor’s
front panel (16x2 LCD).
Display will briefly indicate:
The boot splash screen indicates the firmware version and model name.
The number of active/total MONITORS & SENSORS will be represented here
numerically. There is 1 monitor and 2 sensors in this example.
With the progressing from left to right.
After 5 seconds, display will indicate:
After an additional 5 seconds, if the fans have already been configured, display will indicate:

*NOTE: If fan count is set to 0 (i.e., no fans configured), the Host Monitor will prompt to complete the Boot Fan Setup before warm-up. The
Boot Fan Setup process is outlined on the following pages.

Release Date: 6/15/2021Page 4
BOOT FAN SETUP
When the fan count is set to 0 (i.e., no fans have been configured), the Host Monitor will prompt the user to configure the system during
boot immediately before warm-up. This process will step the user through the setup process. Pressing MENU at any point in the setup
will skip the setup process. Pressing ESC will go back a step. To return to automatic Boot Fan Setup if exited early, ensure the number of
fans is set to 0 and cycle power to the system.
1. The user will be prompted to configure the system. Use UP or DOWN keys to select Yes and press ENTER. Pressing ESC here will
cancel the setup process.
2. The user will then be prompted to set the number of fans that this Host box will monitor. Use UP and DOWN keys to select a number
from 1 – 16. Selecting 0 fans will skip the setup and go into warm-up. Press ENTER to confirm selection.
3. The display will then prompt the user to set the number of sensors per fan. This setting applies to all fans. Use Up and Down keys to
select 1 or 2. Press ENTER to confirm selection.
NORMAL OPERATION
The normal operation screen will display the average temperature & average velocity
or volume of the selected fan or the Fan Summary. The Fan Summary will display
the average velocity or the sum of the volumetric flow for all configured fans. The
selected fan address is indicated in the top right of the screen, for example FSUM
is the Fan Summary and F01 is fan 1. Fans 01 through 16 can be viewed after they
are configured. UP and DOWN buttons are used to cycle through the associated fans
with ESC bringing the display back to the fan summary. Prior to setup, with no fans
configured, it will display the average of all connected sensors discovered on initial
boot and display ‘F-‘ in the top right.
Normal Display Mode
Volume (ACFM) selected for display
4. A prompt to enter setup/configuration of the displayed fan will be displayed. Press ENTER to enter the setup/configuration

Release Date: 6/15/2021Page 5
5. The user will then select the monitor for the fan being setup. Use UP and DOWN to select the monitor to associate with the fan being
setup, H is the Host, 0-F are the Clients. Press ENTER to confirm selection. When Sensors per Fan is setup as 1,the sensor associated
with the fan being setup must be selected. Use UP and DOWN to select either sensor. Press Enter to confirm selection. When Sensors
per Fan is setup as 2, selecting the sensor # is skipped and both sensors of the selected monitor are assigned to the selected fan.
Terminology:
Monitor - A Monitor can be either a Host box or a Client box.
Host - The monitor box which is the interface of the airflow measuring station to the system’s BAS and includes the 5 membrane
push-buttons on the front panel. The Host address will always be shown as MON H.
Client - The monitor box(es) which do not include the 5 membrane push-buttons on the front panel. Data from each Client monitor
box is drawn by the Host monitor box for processing and transmitting to the BAS. Client monitor boxes have a rotary dial that is used
to set the address displayed as MON 0, MON 1, etc., up to MON F (Hex 15). In systems with less than 16 fans, it is recommended to
set the rotary address in the Client monitor box to match the fan number to which it is connected in order to avoid confusion.
6. Steps 4 through 6 will be repeated for any additional fans that need to be setup.
7. The display will indicate when all fans have been setup.
a. When selecting the assignment, there are 2 errors that can be displayed. If there is an error, it is shown as the last character of
the 2nd line. If both errors are present, it will flash between the 2 characters.
Error 1: ‘*’ is present when the selected assignment is not connected or communicating with the host.
Error 2: ‘!’ is an indication that the displayed assignment has been previously assigned by the user to another fan.
NORMAL OPERATION
Under normal operation, the TDFi-RT Host monitor’s front panel will continuously display average airflow and average temperature in
Imperial or SI units from the fan summary or selected fan.
Configuration
The on-board microprocessor in the TDFi-Rt Host Monitor allows for system configuration, operating parameter selection, analog output
configuration, and display filtering. The Host Monitor also acts as a master across a wired network to other Client Monitor boxes, up to
16, and the remote GUI.
The operator or supervisor can verify configuration and change certain parameters, within defined ranges, by entering the TDFi-Rt
configuration mode. This is accomplished using the five membrane pushbuttons located on the TDFi-Rt Monitor Host front panel display
cover.
Membrane Push Buttons
The five membrane push-buttons on the front panel display (MENU, ESC, UP, DOWN, ENTER) are used to interface with the TDFi-Rt Host
Monitor. Membrane pushbuttons are used during system configuration setup and can be used for certain functions when in the Normal
operation mode.
