Switch Settings
GENERAL
The switch settings on the control are very important and
should be set to the appropriate settings prior to making
any adjustments to the control through the User Interface.
The switch settings change the items that are available to
be viewed and /or adjusted in the User Interface.
If a switch setting is changed while the control is powered
up, the control responds to the change in setting by returning
the display to the VIEW menu.
Switch Settings

The Installer /User switch selects the access level of the
control. In the User access level, a limited number of items
may be viewed and adjusted. In the Installer access level,
all items may be viewed and adjusted.
