Figure 43. System Status (Main > System Status)
This section summarizes the most important chiller system information; you can get details about each chiller by using its
keypad/display or the Chiller Status screen.
CSM Operating State
The CSM Operating State variable tells you what state the chiller system is currently in. The chiller system includes
everything under the CSM’s supervision; for example, chillers, cooling towers, and cooling load pumps. Four operating
states are possible: Off, Recirculate, On, and Free Cooling.
Off (Unoccupied)
When the operating state is Off, all chillers, cooling tower fans, and cooling load pumps are disabled. The Off State has
five sub-states:
1. Off: Alarm
2. Off: Manual
3. Off: Ambient
4. Off: BACnet Network
