USER INTERFACE

The control uses a Liquid Crystal Display (LCD) as the method of supplying information. The LCD is used in order to setup and monitor the operation of your system. The con- trol has four push buttons ( FIG. 2) for selecting and adjust- ing settings. As you program your control, record your set- tings in the ADJUST menu table which is found in the sec- ond half of this instruction manual.

MENU

All of the items displayed by the control are organized into two menus. These menus are listed on the top left hand side of the display (Menu Field). To select a menu, use the Menu button. By pressing and releasing the Menu button, the display switches between the two menus. Once a menu is selected, there will be a group of items that can be viewed within the menu, see Figure 2.

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. The items can be quickly scrolled through by holding the Item button and pressing the down arrow button. To rapidly scroll through the items in the reverse order, hold the Item button and press the up arrow button, see Figure 2.

ADJUST

To make an adjustment to a setting in the control, begin by selecting the ADJUST menu using the Menu button. Then select the desired item using the Item button. Finally, use the up arrow button, or down arrow button to make the adjustment. Additional information can be gained by observing the Status field of the LCD. The status field will indicate which of the control's outputs are currently active. Most symbols in the status field are only visible when the VIEW menu is selected, see Figure 2.
