Only when at least one of both elements is plugged in, a powered connection with the CPU 17 can be realized. If not, the system will not work. A powered connection will cause the CPU 17 to generate a warmup signal to the system and the system will proceed with a power level control. In case of a power level above 10% is measured, the system will continue to check the ball sensor 21 signal.

If no such force is measured, eventually after the delay loop has lapsed, the system will shut down, else the system will perform an error check of the fan 3 (i.e. measure a drop in amperage upon fan startup) and check if a filter 12 is placed within the system. If so, the odor processing unit 24 is activated and, consequently, also the fan 3. If not, the system will shut down.
