Event States —
An event state is a specific set of condi-
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.

TOUCH SCREEN SETTINGS
FOR THE CONTROLLER
The Setup screen is accessible only from the controller
touch screen, and is not password-protected by default. To ac-
cess the Setup display, press anywhere on the screen (except on
buttons or text fields) for 4 seconds. The Setup screen is dis-
played. See Fig. 57.
Unit IP Address —
On the Setup screen, press Network
to display the network parameters. See Fig. 58.
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.
