DOCUMENT INTRODUCTION
This document describes the TDP05K Advanced Thermal Dispersion Probe Airflow Measuring System’s features and functions. It also
provides guidelines and instructions for setting up and troubleshooting these devices used in plenum and duct applications.
NAVIGATING THE START-UP MENU
After installing the TDP05K Airflow Measuring System, power on the unit. Menu options appear on the front panel LCD display of the
primary controller and are replicated on the remote user interface (see Figure 1). The LCD display has a 16 character per line, 2-line
display.
Figure1: Front Panel LCD Display of Primary TDP05K Controller & Remote User Interface
The display boot screen indicates the firmware version.
After 5 seconds, the display indicates the number of active probes and sensors. This example indicates one active probe and four total
sensors.
After another 5 seconds, the display indicates that the unit is warming up.

NORMAL OPERATION
The normal operation screens display the average temperature and average velocity or volume in the units selected. When the display is
configured for the International System of Units (SI), the display shows the temperature in Celsius and the average velocity in meters per
second or the volume as liters per minute. See Table 3 for the available units.
When the display is configured for Imperial, the display shows the temperature in Fahrenheit and the average velocity in Actual Cubic Feet
per Minute. See Table 3 for the available units.
You can use these push buttons during system configuration setup and while performing certain functions in the normal operation mode.
NOTE: An asterisk (*) appears on the top left corner of the display if the number of sensors has changed during normal operation mode.
CONFIGURATION
The on board microprocessor in the TDP05K primary probe allows for system configuration, operating parameter selection, analog output
configuration, and display filtering. The primary probe is the automation interface and also acts as a primary across a wired network to
other ancillary probes (up to 15) and the remote display when that option is selected.
NOTE: Each primary and ancillary probe automatically reports temperature and flow based on the number of installed sensors (1 through 8)
per probe.
Verify configuration and change certain parameters, within defined ranges, in the configuration mode.
MEMBRANE PUSH BUTTONS
You can use the five membrane push buttons (MENU, ESC, UP, DOWN, and ENTER) on the front panel display cover to interface with the
TDP05K primary controller.

Press the UP or DOWN buttons to scroll through the available menu and submenu options. Press ESC to return to the previous menu
without making updates to the currently selected option. Press ESC from the Operator or Supervisor Menu to return to normal operation
mode. Press MENU at any time to return to the normal operation mode. To enter numerical values into a submenu selection option, enter
the digits one at a time beginning with the leftmost digit. Press UP or DOWN to scroll through the numbers 0 through 9. When the correct
value is displayed, press ENTER. The cursor automatically moves to the next position. If an error is made after pressing ENTER, press ESC
to return to the previous digit.
1. Enter the 4-digit PIN to access the Operator Menu. PIN entry is made one digit at a time beginning with the left most digit.
Press UP or DOWN to scroll through the numbers 0 through 9.
2. When the correct number is displayed, press ENTER to select the digit. The cursor automatically moves to the next position.
If an error is made after you press ENTER, press ESC to go back and change the digit.
NOTE: If the PIN is not correctly entered, the display returns to normal operation.
b. If the Operator PIN is not enabled, the Operator Menu selections display.
NOTE: See Enable, Disable, and Change the Operator PIN for more information about enabling the PIN.
3. Press UP or DOWN to scroll through the available menu selections. See Table 1 for a list of Operator Menu submenus and their
descriptions.
NOTE: Each Operator Menu submenu has submenu selections to access the configurable options.
NAVIGATING THE OPERATOR MENU
The Operator Menu allows you to view, set, or change system parameters. System configuration setup in the Operator Menu may be
required when connected to a building automation system.
1. During normal operation when the LCD screen displays the average temperature and average velocity or volume, press MENU and
UP or DOWN until the arrow is next to Operator Menu.
2. Press ENTER to enter the Operator Menu submenu options.
a. If the Operator PIN is enabled, the LCD screen displays the following message:
NAVIGATING THE MENU OPTIONS
The left arrow (→) symbol appears on the left side of the currently selected menu, submenu, or option. Press ENTER to access the
selected option.
The up and down arrow (↕) symbol on line two of the display indicates that the selected digit or character can increment and decrement
one character or digit at a time. The character or digit blinks when selected.
