3.6 CONFIGURATION MENU
The Configuration Menu shown in Table 3-4 permits adjustment of the Internal Setpoint
(Setpt) temperature regardless of whether the valid password has been entered. Setpt is
required for operation in the Constant Setpoint mode. The remaining options in this menu
require the valid password to be entered, prior to changing existing entries. This menu
contains a number of other configuration settings which may or may not be displayed,
depending on the current operating mode setting.
NOTE
The Configuration Menu settings shown in Table 3-4 are Factory-Set in accordance with the
requirements specified for each individual order. Therefore, under normal operating
conditions, no changes will be required.
