Adjusting Settings and Options
Password Entry
This section describes how to access the TEC 3000 menus and adjust the various settings and
options. With password entry enabled, the controller will prompt for a password anytime a user
attempts to access the setup menus. A flashing cursor on the password entry screen will make it
clear which digit is being changed. Feature is available with Firmware Version 2.02.
These instructions will start from the main monitoring display screen, assume password entry mode is
enabled, and the user has Security Level 4 clearance. Once in the setup menus, the user can press
the “ESC” key to exit that menu level or press the “ESC” key repeatedly until the display returns to the
main monitoring screen. After 30 seconds of inactivity, the display will automatically return to the main
monitoring display screen.
TEC 3000 controllers with newer displays have the added functionality of a quick reference scroll
menu. Pressing the up and down arrow keys simultaneously while on the main monitoring screen will
display the controller’s serial number and firmware version. Pressing the up or down arrow keys will
then scroll through the level, temperature, and gas bypass settings. The user can return to the main
monitoring screen by pressing the “ESC” key or waiting 30 seconds.
