Unlike most areas of the system, navigation is performed exclusively with the Page Left and
Page Right arrows to move from screen to screen in round-robin fashion. The order of
navigation depends on whether the unit is part of a BST Cascade or a standalone unit. The
order of navigation is as follows:
Screen Name
BST
Standalone
Unit Status
✓
✓
Plant Status

BST Cascade Status
✓
SmartPlate Status (if connected)

If there is a fault condition, the fault indicator will appear below the screen’s title bar at the top of
the screen.
7.1 Ignition Sequence
When the unit starts the ignition sequence, the Ignition Sequence screen automatically
appears (see Figure 7.1.1, below). This screen displays the status of each step in the ignition
sequence on five rectangles, with the first step, Demand, at the bottom. The rectangle for each
step is grey before starting, then turns green when the step successfully concludes. Various text
notes appear on the right side of the screen at each step. The last screen, Last Ignition Status
(Figure 7.1.6), serves as a summary screen. This summary remains in effect until the next
successful ignition.
The ignition process, which starts with a call for heat, consists of the following steps:
1. Demand
2. Auxiliary Delay: (Demand turns green)
3. Purging: (Demand and Aux Delay turns green)
4. Spark Cleaning (Demand, Aux Delay and Purging turns green)
5. Ignition (Demand, Aux Delay, Purging and Spark Cleaning turns green)
6. Summary (All stages turns green)
