Figure 13 - Valve Control Scenario 1
5.4.2 Scenario 2
In this scenario depicted in Figure 14, none of the boilers are firing and all of the valves are
open. All MOVs are placed in the “OPEN” position. A boiler MOV can be manually closed by
selecting the “Valves” touch screen.
The scenario sequence is described as follows (See Figure 11).
1. From the Main screen press the “VALVES” touch screen button (see Figure 11, Screen1).
2. This brings the user to Screen 2 where either the “VALVES 1-2” or “VALVES 3-4” screens
may be selected by pressing their corresponding touch screen button. The user is now
brought to either the “VALVE 1-2” screen (Screen 3) or the “VALVE 1-2” screen (Screen 4).
If the “BACK” touch screen button was pressed instead, the user would have navigated back
to the Main screen.
