Frequently Asked Questions

▶

Does it work without room sensors?

Yes, the thermostat operates independently using its built-in temperature sensor. Room sensors provide additional reference points for enhanced control but are not required for basic operation.

Is professional installation required?

No, the T9 is designed for DIY installation with included C-wire adapter. However, professional installation is recommended if you're unsure about your HVAC system compatibility or wiring configuration.

How long do rooms stay prioritized?

The sensor uses an occupancy algorithm that initially sets a 10-minute priority when motion is detected. For continuous occupation, the timeout automatically extends based on ongoing motion events.

What happens if no rooms show occupancy?

The system defaults to using the main thermostat's temperature sensor. If geofencing is enabled and no one is detected home, it switches to away mode settings.
