I have this installed in a vacation property. I have a daily program and an away setting. I want the away setting to take priority over the schedule. If it's empty I don't want the heat running every morning based on the schedule even though it's showing me it's in the away mode. I'd like the heating to should start when someone gets up and it senses someone is home. Would removing the schedules cause it to work based only on the home and away settings? Is this something I have to manually change in between each guest?
