Turning the Password Protect Feature On or Off
If your THZ-100 thermostat was initially setup through the MRX Advanced
Network System Controller with the Use Pass-Code Lockout feature enabled
on the Advanced Thermostat Settings then Password shows as an item in
the Options screen. The current state of the password protection, whether
on or off, is displayed on the right side of the display. Otherwise, this item
does not display.
Entering your password toggles this feature on and off. If you desire to toggle
the state of the password protection then use the arrow keys to move the
highlight bar to Password.
Press the key below the OK key label in the smart-key label at the bottom
right of the display to select this option. If you decide to cancel the operation
then press the key below the Go Back key label in the smart-key label at
the bottom left of the display.
After selecting OK, the LCD screen displays either Turn ON Password
Protection or Turn OFF Password Protection at the top of the screen as
appropriate. The number 9 appears four times across the center of the
screen followed by the word Done. The number 9 on the left side of the
display is highlighted with small arrows above and below the number.
At the bottom of the screen are three smart-key labels for the three buttons
located below the LCD display. The left button is Cancel, the center button
is a left arrow, and the right button is a right arrow.
To enter your password, use the Up and Down arrow keys to enter a number
between 0 and 9, then use the left or right arrow smart-keys at the bottom
of the page to select the next digit to be entered.
When you have entered all four digits of your password then use the right
arrow smart-key to move the highlight to the word Done. At this point, the
right smart-key changes from a right arrow to Enter. Press the key below
Enter to enter your password. If you enter the password correctly then the
LCD screen changes back to the thermostat main screen; otherwise, the dis-
play maintains the password entry screen.
