The integrated Passive Infrared (PIR) motion sensor tracks human activity in front of the cooler. The controller divides the week into 30-minute blocks. If activity is recorded across consecutive days during specific blocks, the system marks those periods as "Operational." If no movement is detected for the duration of the SOT (Saving Overtime) parameter, the controller automatically drops into "Saving Mode." High Temperature Management (HTM)
