Reducing Power Consumption with Mode Lock
Enables more efficient system operation by lowering the maximum power consumption value, as well as locks the mode of operation (Exam-
ple: In a cooling-only server room application where permission to adjust the system mode is highly limited). Changing modes can cause a
change in compressor frequency, which would cause problems with the setting. As such, if this mode is used, it is locked in either cooling or
heating. The function is rarely, if ever, used.
1. Shut power down to the system.
2. Set DIP Switches as indicated below, following the steps and chosen mode.
3. Turn power on to the system.
Step 1: Reducing Saving Power Consump-
tion + Mode Lock (Cooling).
