Hey there Indyrn44,
If I understand correctly I think I know what you're asking. You're wanting to just schedule your thermostat to change the temperature at a certain time of day, once, and then be done. Is that correct?
If so, it's not a setting that exists currently, but you can set a temperature schedule by reviewing this article and then you can turn if off or cancel the schedule.
Please let me know if you have any further questions or concerns.
