Event States

An event state is a specific set of conditions that the controller
may encounter when controlling the chiller. Event states are re-
peatable and predictable, and represent known states of the
control. When the control is in a particular state, a unique mes-
sage is associated with that state. The event state messages are
displayed on the default screen of the control panel and are list-
ed in Table 18.

CONTROLLER SETTINGS

The controller settings are accessible through the Configuration
Menu when logged into the Factory account.

Unit IP Address

On the Configuration Menu screen, press Ethernet Configura-
tion to display the network parameters. See Fig. 46.
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.
To change IP address manually, select Ethernet Configuration
from the System Configuration Menu. See Fig. 46.
Fig. 46 — Ethernet Configuration
Enter the new address and validate it by pressing Apply. Return
to the Network screen and enter the subnet mask and default
gateway using the same method. Then return to the application
and save the changes. See Fig. 47.
