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.
