This output variable is the current operating mode of the node
determined by many inputs and arbitrated by control logic.
CTL_PRESSURIZE disables the heat/cool outputs, fan runs at
highest speed.
CTL_DE_PRESSURIZE disables the heat/cool outputs, fan is
turned OFF.
CTL_MODE_MANUAL allows turning outputs ON/OFF manually
through nviTest.
CTL_MODE_FACTORY_TEST is intended only for the factory.
CTL_FLOATING_OUT_SYNCH allows enough time (150% valve
run-time) for the valve(s) are at their initial positions (control
algorithms are active). The controller then goes into one of the
