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 T6 Pro
Smart thermostat will automatically use your smartphone’s location, which
can save energy when you leave and make your home comfortable by the time
you return. See page 13 for more.
• Smart scheduling: Adds a Sleep period to location-based temperature
control. See page 13 for more.
• 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. See page 15 for more.
• No schedule: You can also choose not to set a schedule and adjust the
thermostat manually. See page 18 for more.
Tip: The Honeywell Home app can be used to manage multiple thermostats and
multiple users in a household.
Smart Alerts: The T6 Pro 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 T6 Pro Smart
thermostat can automatically determine whether your home needs heating or
cooling to reach the desired temperature.
Adaptive Intelligent Recovery: The T6 Pro Smart thermostat learns your heating
and cooling cycle times to make sure the system delivers the temperature you
want, when you want it.

Built-in compressor protection
If the compressor is restarted too soon after
a shutdown, system damage can occur. The
built-in compressor protection feature forces
the compressor to wait a few minutes before
restarting, helping to prevent damage to the
heating or cooling system.
During the brief wait period, the thermostat will
flash Cool On (or Heat On if you have a heat
pump) until the wait period is over, at which point
the compressor will turn back on.
Note: The flashing Cool On or Heat On message
is also used for startup delay protection if AC
power loss occurs.
Setting the fan
Touch Fan on the thermostat home screen to
cycle through available fan modes until the
desired mode is displayed. Your changes will
save automatically.
Available fan modes:
• On: The fan will run continuously.
• Auto: The fan will run only when the heating
or cooling system is on.
• Circ: The fan will run at random intervals at
least 35% of the time to keep air circulating
throughout your home.

Location-based temperature control and smart scheduling
Location-based temperature control uses geofence technology and your
smartphone’s GPS location to automatically adjust your thermostat as you come
and go. When you leave the geofence boundary, the thermostat will change to
your preferred Away temperature, and when you enter the geofence boundary, the
thermostat will change to your preferred Home temperature.
Setting location-based temperature
control and smart scheduling in the
Honeywell Home app
These two options can only be activated using
the Honeywell Home app. To enable locationbased temperature control and/or set a smart

Troubleshooting
If the thermostat screen is blank:
• Check the circuit breaker or fuse that’s connected to your heating or cooling
system and turn it on if it’s switched off.
• Make sure the power switch at the heating or cooling system is on.
• Make sure the furnace door is closed securely.
If the screen is difficult to read:
• Increase screen brightness (see page 22 for instructions).
If the heating or cooling system isn’t responding:
• Touch Mode on the thermostat home screen and set the system to Heat. Make
sure the temperature set point (the smaller of the two numbers) is higher than the
indoor temperature (the large number in the center of the screen).
• Touch Mode on the thermostat home screen and set the system to Cool. Make sure
the temperature set point (the smaller of the two numbers) is lower than the indoor
temperature (the large number in the center of the screen).
• Check the circuit breaker or fuse that’s connected to your heating or cooling
system and turn it on if it’s switched off.
• Make sure the power switch at the heating or cooling system is on.
• Make sure the furnace door is closed securely.
• After making these changes, wait 5 minutes for the system to respond.
If the temperature setting doesn’t change:
• Make sure the heating and cooling set points are within the operating range.
– Heat: 40 ºF to 90 ºF (4.5 ºC to 32.0 ºC)
– Cool: 50 ºF to 99 ºF (10.0 ºC to 37.0 ºC)
If Cool On or Heat On is flashing:
• The compressor protection feature is engaged. Wait a few minutes for the system
to safely restart to avoid damaging the compressor. See page 9 for more
information.
