5.2 CONTROLLER DISPLAY
The BC1 uses a Liquid Crystal Display (LCD) as a method of supplying information. You use the LCD in
order to setup and monitor the operation of your system. The BC-1 uses three push buttons (Item, ▲, ▼)
for selecting and adjusting settings. As you program your control, record your settings for future reference.

Menu
All of the items displayed by the control are organized into two menus. These menus are listed on the
upper right hand side of the display (Menu Field). The default menu for the BC-1 is the View menu. While
in the View menu, the VIEW segment is displayed. To select the Adjust menu, press and hold
simultaneously all three buttons for 1 second. The display then advances to the Adjust menu and the
ADJUST segment is turned on in the display. The display will automatically revert back to the View menu
after 20 seconds of keypad inactivity. Once in a menu, there will be a group of items that can be viewed
within that menu.
Item
The abbreviated name of the selected item will be displayed in the item field of the display. To view the
next available item, press and release the Item button. Once you have reached the last available item in a
menu, pressing and releasing the Item button will return the display to the first item in the selected menu.
Adjust
To make an adjustment to a setting in the control, begin by selecting the Adjust menu by pressing and
holding simultaneously all three buttons. Then select the desired item using the Item button. Finally, use
the ▲ or ▼ button to make the adjustment.
