The OCTO has only PWM connections, so can not control via 3Pin and the voltage.
The sense of a delta control times leaving aside the Aquaero can calculate a delta, with directly connected sensors, I can not say anything about the OCTO, because I do not own one.
Both devices do not need the software for operation, as long as all sensors are connected directly and no software sensors are used, they run as set as long as they get power.
