You do not have to create an EMS routine. You can create a new fractional schedule that has a value of 1 from 6 AM to 9 PM and 0 for the rest of the day (9 PM to 6 AM). Then you can assign the schedule you just created to the fan as the Availability Schedule. This means that the fan will only be allowed to run from 6 AM to 9 PM (which is what you want) and it will be forced to be off for the rest of the day (9 PM to 6 AM).
