Detailed procedures
The following sections provide detailed information about the controller UI and the setup
procedures for the controller.
Controller UI
The controller’s system status and setup information displays on an LCD UI with adjustable
brightness. The four status indicator icons show the defrost, cooling, evaporator fan, and alarm
features and provide a visual indication of the system status and alarms. The
Defrost
and
Alarm
icons also function as keys. You can use these keys to initiate unscheduled defrost cycles and
clear system alarms. You can also use the four touchpad keys to navigate the system, see system
information, change parameter settings, and respond to system alarms.
The following figure shows the controller’s UI, icons, and keys. Table 5 describes the user interface
behavior and user actions.
