Benchmark 750-3000 Boiler Operation & Maintenance Manual
SECTION 2: OPERATION
2.6 CONFIGURATION Menu
The Configuration menu 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.
A full description of each item appears in Appendix A-3.
NOTE:
The Configuration menu settings are Factory-Set in accordance with the requirements specified
for each individual order. Under normal operating conditions, no changes will be required.
