How To Use The Data Brochure

This brochure is organized into four main sections. They are: 1) Sequence

of Operation, 2) Installation, 3) Control Settings, and 4)

Troubleshooting. The Sequence of Operation section has four sub sections. We recommend reading Section A: General of the
Sequence of Operation, as this contains important information on the overall operation of the control. Then read to the sub sections that
apply to your installation.

The

Control Settings section (starting at DIP Switch Settings) of this brochure 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.

User Interface

The 362 uses a Liquid Crystal Display (LCD) as the method of supplying information. You use the LCD in order to setup and monitor
the operation of your system. The 362 has four push buttons (Menu, Item, , ) for selecting and adjusting settings. As you program
your control, record your settings in the Adjust Menu table which is found in the second half of this brochure.

Menu

All of the items displayed by the control are organized into various menus. These menus are
listed on the 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 will advance to the next

available menu. Once a menu is selected, 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 appropriate menu
using the

Menu button. Then select the desired item using the Item button. Finally, use the

and / or button to make the adjustment.

Additional information can be gained by observing the Status and Pointers fields 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.
