THZ-100 THERMOSTAT
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 display maintains the
password entry screen.
