By utilizing temperature sensors, limits can be set to prevent the temperature from getting too hot or cold, thus reducing wasted energy while maintaining a comfortable climate. Additionally, schedules are established to reduce HVAC usage during the day; as the workday (or school day) ends, the temperature returns to a comfortable level.
And with remote access, you can turn the heat (or AC) down while youre away. If need be, you can
temporarily
turn it up so friends and neighbors can check on the home.
