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

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 refer to the sub sections that

apply to your installation.

The

Control Settings

section of this brochure illustrates the menu screens that are built into the control. These menu settings are

referenced to the specific section in the

Sequence of Operation

User Interface

The 262 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 262 uses four push buttons (Menu, Item, , ) for selecting and adjusting settings. As you program

your control, record your settings in the actual settings column of the Adjust Menu. The table is found in the second half of this brochure.

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

button. By pressing and releasing the

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.
