SECTION 2: OPERATION

2.9 BST (Boiler Sequencing Technology) Menu

The BST menu must be enabled in order to be displayed and accessed. The BST Menu item,
located at the end of the Configuration menu (item 37 in Table 2-4), must be set to Enabled.
The BST menu contains all of the items required to configure, operate and monitor the
functionality of the BST System. There are over 50 items in this menu, and selecting any
particular item from the list, for inspection or modification, could be time consuming. As a result,
the BST menu has been segmented into FIVE logical groups based on functionality.
The five Item groups are:
1. BST Monitor Items
2. *BST SETUP MENU*
3. *OPERATE MENU*
4. *TEMP CTRL MENU*
5. *BST COMM MENU*
These displayed item groups are displayed in UPPER CASE letters, and are bounded by an
asterisk * in order to readily identify them within the item list.
The Items contained in group 1 (BST Monitor Items) are always displayed within the menu, as
these items are critical for proper system operation. Therefore, the BST Monitor Items Header
itself is not displayed.
The Items contained in groups 2-5 are not displayed unless that particular item group has been
enabled from the C-More keypad.
