What does room prioritization mean and how does it work using the T9/T10 thermostat?

You can select which rooms/smart room sensors you want your thermostat to focus on (which rooms it should measure). For example, during nap time, you may want the nursery room prioritized so the baby sleeps at the ideal temperature. In this case, you can set the priority via a simple voice command; or those rooms are prioritized when people are detected in them. You can even select multiple rooms to be prioritized, like all 3 of the bedrooms, and the thermostat will heat or cool the home based on an average of those rooms.
