Run mode
When the control command that comes from the control panel is ON, the controller is in RUN
mode. That means the controller is ready to use.
Figure 67: Run mode
The multi-status display functions as a simple bar graph when the unit is in RUN mode. The graph
tells you what the control output of the unit is from 0% to 100%.
Ready mode
When the control panel command is OFF, the controller is in READY (stand-by) mode. The controller
is waiting for the command to shift to RUN mode.
In READY mode, the multi-status display flashes slowly. All the lamps in the display are lit.
