Once an event is in APPROVED status, your HVAC will automatically engage and disengage using the Set-up/Tear-down times. However, if they are not included on the event details page, it will look at the Event Start/End times.
The only EXCEPTION is if you have Override times entered on the event details page (see example below). They will be looked at FIRST. For example, if you have an approved event with a Setup time at 6:30 AM but the actual event Start time is not until 3 PM, you may not want the HVAC engaging at 6:30 AM. So, you can choose an override time that would start the HVAC at Noon to start cooling the space prior to the event start time.
You also have the option here to TURN OFF the HVAC for the event. Simply check the box that says "TURN OFF HVAC FOR THIS EVENT".
