Questions about this item
Does the T8850 package include any remote or outdoor sensors, or must those be purchased separately?
The thermostat accepts a remote sensor or an outdoor sensor, but neither is listed as included in the box, so plan to buy the sensors you need separately.
With 4 heat and 2 cool stages available, how do I know which stage configuration matches my HVAC system?
The unit supports up to 4 heat and 2 cool stages for gas, electric, heat pump or dual-fuel systems; match the stage count to your equipment's specifications to choose the right wiring setup.
How does the 365-day holiday scheduling work once the thermostat is installed and connected to Wi-Fi?
You create a full year of holiday or vacation programs on the touchscreen or through the free mobile app, and the T8850 will automatically apply those schedules on the designated dates.
