This brochure is organized into four main sections. They are: 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 of the Sequence of Operation, as this contains important information on the overall operation of the control. Then read 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.
The 265 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 265 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 the 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.
The items can be quickly scrolled through by holding the
Item
button and then pressing
the
▼
button. To rapidly scroll through the items in the reverse order, hold the
Item
button
and press the
▲
button.
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 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.
