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
