Advanced Features ADAPTIVE RECOVERY Over time, the T9 thermostat “learns” how long it takes your system to reach your programmed temperature setting. The thermostat turns on the heating/cooling system early and assures that the programmed temperature setting is reached at the programmed time regardless of weather conditions. For example, if the Wake program period is set to 6:00 am with a heat setting of 70 degrees, the heat will turn on before 6:00 am, so the temperature is 70 degrees at 6:00 am.

Battery Replacement (indoor sensor) The T9 thermostat does not use any batteries. It is powered by 24 volts from the HVAC transformer using the C (common) wire. The wireless indoor sensors use AAA Alkaline batteries. Batteries: Replace batteries in your indoor sensor when a warning appears on the thermostat screen, about 60 days before batteries are depleted. When the sensor status light begins flashing red, battery power is critically low and will be depleted within 2–3 weeks.
Frequently Asked Questions (FAQs) Wi-Fi connection questions Q: Will the thermostat still work if the Wi-Fi connection is lost? A: Yes, you can still manually adjust the temperature at the thermostat. However, some features such as location-based temperature control (geofencing technology) can only be managed through the Honeywell Home app and will not function without a Wi-Fi connection. The thermostat will automatically reconnect to Wi-Fi once the network is restored.
Other questions Q: How can I uninstall my T9 Smart thermostat? A: If you want to replace your T9 Smart thermostat, or if you’re moving out of your home and leaving the thermostat behind, you’ll first want to clear out the personal settings that are stored on the thermostat. (Even when disconnected from power, the thermostat will keep your settings and home router information in memory.) We recommend resetting the thermostat’s Wi-Fi and HomeKit settings (if previously connected).
