Example
Problem:
We have a variable frequency drive for air conditioning in a warehouse. It needs to run between 7:00 A.M. until
5:00 P.M. on weekdays, and 9:00 A.M. until 1:00 P.M. on weekends. Additionally, the drive must be manually
forced to run outside working hours if there are people in the building, and must continue to run for 30
minutes afterwards.
