User configuration menu
The VZ7656X series of controllers feature an intuitive,
menu-driven, back-lit LCD display that walks users and
installers through the configuring steps, making the
configuring process extremely simple. This menu is
typically accessed by the user to set the parameters
such as the clock time set, the schedule time events
and the system mode.
It is possible to bring up the user menu at any time by
depressing the MENU key. The status display automatically resumes after exiting the
user-configuring menu.
If the user pauses at any given time during configuring,
Auto Help
text is displayed to
help and guide the user through the usage and configuring of the controller.
