How does temperature limit work?

Temperature limit is our new feature that allows you to use your Smart Vents and ecobee3 room sensors like a room-by-room thermostat. When you have a room with a Smart Vent and room sensors, you can set a temperature limit at which the Smart Vent will automatically open or close to prevent overshooting the target temperature. This redirects air to rooms that have not hit their limit and reduces HVAC run time overall. It balances room temperatures and lets each room be treated like an independent zone. In our testing, temperature limit can shift room temperature by 4-8 degrees.
