PC20

The Power Management Unit is the brain of the system. It receives requests from switches or keypads and handles these commands based on the current state of the system. The output may be the activation/deactivation of a circuit or starting a timer function. The PowerCore then sends status data from system to keypads to turn on/off the LED indicators and backlighting.
