Resetting the Management Password

UTY-RVNYN touch panel wired remote controller
Local procedure for replacing a forgotten or unavailable four-digit management password
The UTY-RVNYN provides protected access to initial and management settings. When the existing management password is unavailable, a new password can be registered directly from the controller's password verification screen by using the physical Menu and Cancel buttons.
Important: The reset replaces the existing management password. Record the new password securely and only provide it to authorised personnel.
