Password Setting - Honeywell TB3 Series Installation Instructions Manual

PASSWORD SETTING

IMPORTANT:
It is recommended that a 4-digit pin be set during the first installation. The pin should be kept confidential and
should be changed frequently.
Users must set a password when the thermostat is installed for the first time or restored to factory settings. The
thermostat will display a screen to configure the password in these cases. The password digit can be selected using
the "Main Parameter Increase Key" (Mode Key). The value of that digit can be changed using the "Value Increase
Key" (Up key) and "Value Decrease Key" (Down key). The password entered during the thermostat's setup must be
confirmed with the Fan key.
When the correct password is entered, the configuration menu is displayed. If the incorrect password is entered, the
process will fail, and the password will be reset. After 3 incorrect password entries, new password cannot be entered
for 180 seconds.
The thermostat returns to the main screen if no action is taken within 10 seconds. In 30 seconds, the parameter
setting screen will return to the main screen if no action is taken. All parameters are stored in the device, ensuring no
data is lost if the thermostat is turned off.
NOTE:
Password rules
• There can be no blank spaces.
• All digits cannot be the same.
