Event States — An event state is a specific set of conditi-
osn that the controller may encounter when controlling the
chiller. Event states are repeatable, predictable, and represent
known states of the control. If the control is in a particular state.
a unique message is associated with that state. The event state
messages are displayed on the default screen of the control
panel and are listed in Table 17 below.
