FAQ: Why don't my setpoint changes hold until tomorrow?

Depending on the type of schedule your zone is following, setpoint overrides will be treated differently. Below is a quick take on how setpoint overrides will be treated when the zone is following different schedule types. 

Building Schedule - Overrides hold until the end of the current occupied period. Then go back to the scheduled setpoints

Zone Schedule - Overrides change the desired temperature for the zone schedule for that day indefinitely. 

Named Schedule - Just like building schedule overrides, hold until the end of the current occupied period.
