User configuring instructions menu
The VT76x7 series of Terminal Equipment Controller
feature an intuitive, menu-driven, back-lit LCD display
that walks users through the configuring steps, making
the configuring process extremely simple. This menu
is typically accessed by the user to set the parameters
such as temperature and time events, system mode,
fan mode, etc.
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 Terminal Equipment
Controller.
Ex.:
Press yes key to change cooling temperature setpoint
Use the up or down arrow to adjust cooling setpoint
