6.5. Event States
A event state is a specific set of conditions which the controller may encounter when controlling the
chiller. Event states are predictable and repeatable and represent known states of the control. If the
control is in a particular state, there is a unique message associated with that state. The event states
message are displayed on default screen of control panel.
