Thermostat Features
Flexible scheduling: You can choose to use location-based temperature control (geofence technology), program a set schedule or
use a combination of both to make sure your home is always comfortable.
• Location-based temperature control: Using geofence technology, the T9 Smart thermostat will automatically use your
smartphone’s location, which can save you energy when you leave and make your home comfortable by the time you return.
• Smart Scheduling: Adds a Sleep period to location-based temperature control.
• Time-based scheduling: You can program a schedule where every day is different, a schedule where weekdays and
weekends are different or a schedule where every day is the same. There are four adjustable periods per day: Wake, Away,
Home, and Sleep.
• No schedule: You can also choose not to set a schedule and adjust the thermostat manually.
• You can also choose not to set a schedule and adjust the thermostat manually
• Schedule Using Sensors
• Up to 20 wireless indoor temperature/humidity/motion sensors per thermostat.
• Sensor Priority for each program period or when used manually.
Tip: The Honeywell Home app can be used to manage multiple thermostat and multiple users in a household.
Smart Alerts: The T9 Smart thermostat will send alerts for things like extreme indoor temperatures and reminders for
!
things like filter changes.
Auto change from heat to cool: When Auto mode is selected, the T9 Smart thermostat can automatically determine
whether your home needs heating or cooling to reach the desired temperature.
Adaptive Intelligent Recovery: The T9 Smart thermostat learns your heating and cooling cycle times to make sure the
system delivers the temperature you want, when you want it.

Auto Changeover operation
Auto changeover is available if the thermostat is configured for at least 1 heat stage and 1 cool stage and the installer enabled
auto changeover.
When configured this way, you can select “Auto” as one of the options under “System mode”.
When in auto mode, you can always set the heat and cool setpoint to the same temperature, although most customer prefer to
have a cool setpoint that is at least 3 degrees above the heat setpoint.
A 1.5°F differential is enforced behind the scenes to ensure the heat doesn’t come on after cooling shuts off or vice-versa.
Em Heat mode
Emergency heat runs when you manually switch the thermostat to the em heat mode. When the thermostat is in emergency heat
mode, the heat pump is locked out. When the thermostat is set to em heat mode, the heat pump is locked out and the backup
heat is used to maintain the heat setpoint.
Emergency heat mode is only available when the thermostat was configured for a heat pump with Backup heat by the installer.
From home screen touch the menu icon and then “system Mode”. You can set the thermostat to heat, off, cool, emergency heat,
or auto (auto only available if configured by installer).
