This instruction manual is organized into four main sections:

1) Sequence of Operation, 2) Installation, 3) Control

Settings, and 4) Testing and Troubleshooting. The

Sequence of Operation section has seven sub-sections. We

recommend reading Section A: General Operation of the

Sequence of Operation, as this contains important informa-

tion on the overall operation of the control. Followed by the

sub-sections that apply to your installation. The Control

Settings section (starting at DIP Switch Settings) of this

instruction manual describes the various items that are

adjusted and displayed by the control. The control functions

of each adjustable item are described in the Sequence of

Operation.

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.

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.
