You're describing the 'Follow Me' or motion-based Priority feature. It uses the wireless room sensors to detect activity and averages the temperature of occupied rooms.
To control this:
- Press Menu on the thermostat, then navigate to Priority.
- You will see options for selecting specific rooms manually or using motion detection.
- To let comfort follow you, ensure the setting for using motion detection in active rooms is enabled. Rooms where motion is detected will contribute to the average temperature.
- To prioritize a fixed set of rooms, disable motion detection and manually select the rooms you want.
If that didn't work: Verify your wireless sensors are connected and have a good signal. A sensor with a weak connection or dead battery may not report occupancy correctly. Also, ensure the sensors are placed where motion is easily detected, not behind furniture.
Heads up: The system creates an average temperature from the selected or active rooms. An unselected room or a room without recent motion will not factor into that average, which might explain why it feels different in certain parts of the house.
