I have set up a schedule for my air-conditioner, but I found that the energy consumption data I got from my simulation is abnormal, according to the result, my air-conditioner is not switched off and on according to my schedule, but it is turned on all the time.

You can compare it with the occupancy schedule, and check if it is the energy for the minimum ventilation requirement.

Thank you for your reply, I checked my timetable and that’s how I have it set up, but it still comes up.
