An event state is a specific set of condi-
Event States —
tions that the controller may encounter when controlling the
chiller. Event states are repeatable, predictable, and represent
known states of the control. When 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 con-
trol panel and are listed in Table 19.

If "Enable DHCP" is checked the PIC 5 will attempt to
automatically populate IP settings from Dynamic Host Con-
figuration Protocol (DHCP) server.
NOTE: You must request an IP address, the subnet mask,
and the default gateway from the system administrator
before connecting the unit to the local Ethernet network.
