THZ-100 THERMOSTAT
Password Protection
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 an Enter Password Below displays any time a key is pressed after a period of inactivity. Otherwise, this item does not display.
This screen displays the number 9 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. 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, 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 the LCD screen changes back to the thermostat Main screen; otherwise, the display maintains the password entry screen.
To turn the password protection OFF go to the Password screen in the thermostat Options as described below.
