Thermostat features
The Honeywell T6 Pro ZWave Programmable Thermostat is a ZWave Plus certified
thermostat designed to work with any ZWave compliant controller or gateway for easy
programming and automation to deliver energy savings and comfort at the same time.
When integrated with the app that controls your ZWave controller, it lets you program
and control your home’s HVAC system as well as control other ZWave devices
connected to the same ZWave controller.
Smart Scheduling: You can choose whether you want the thermostat to follow just
Home/Away temperature triggered by your ZWave controller or if home, whether you
want to differentiate between Home/Sleep temperature.
The T6 Pro ZWave thermostat can also work as regular programmable thermostat
when disconnected from your ZWave network. You can program a schedule where
every day is different or a schedule where weekdays and weekends are different with
four periods per day.
Displays ambient air temperature, % relative indoor humidity and reports HVAC
system status: You can display actual temperature or % relative humidity, or to see
whether your cooling / heating system is running.
Auto change from heat to cool: When Auto mode is selected, the T6 Pro ZWave
thermostat can automatically determine whether your home needs heating or
cooling to reach the desired temperature at the right time.
Smart Alerts: The T6 Pro ZWave thermostat can alert you when your HVAC
system is not working properly and can remind you for things like when to change
your furnace filter.
Adaptive Intelligent Recovery: The T6 Pro ZWave thermostat learns your
heating and cooling cycle times to make sure the system delivers the temperature
you want, when you want it.

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.

To include or exclude the thermostat from ZWave
network, go to thermostat
MENU/ZWAVE SETUP.
• Touch Select. You will be asked to set your primary
controller to INCLUDE MODE. Please refer to
the user manual of your ZWave controller.
• After inclusion procedure has been initiated
on your ZWave controller, touch Select on the
thermostat.
• If the inclusion procedure is successful,
"INCLUDED", the node ID, and the ZWave
connected status icon appear on the screen.
If the procedure fails, “FAILED TO INCLUDE”
appears on the screen.
• Your controller will indicate whether the thermostat was successfully added to its
network. (Please refer to the user manual of your ZWave controller.)
NOTES:
• Before adding the thermostat to a ZWave network, check that it does not already
belong to one. If the thermostat is included in ZWave network, it offers to exclude.
If the thermostat is excluded from ZWave network, it offers to include. You can
also check the status by viewing the Node ID located in the thermostat MENU/
DEVICE INFO. An excluded thermostat should show zero for the Node ID (000).
• Whether you are including or excluding thermostat from your ZWave network, first
you have to initiate it on your ZWave controller. Please refer to the user manual of
your ZWave controller.
• For other specific tasks, such as adding the thermostat to home automation
scenes or groups, refer to the ZWave controller instructions.
• The T6 Pro ZWave thermostat works in the optional ZWave battery mode or
normal power mode based on its power source. The ZWave power mode can only
be changed when thermostat is NOT included in ZWave network. You can check
the power mode in the thermostat menu under MENU/DEVICE INFO.
• If 24 VAC power source is not used or available, the thermostat must be powered
by batteries. The thermostat will operate in LSS mode (power-save, sleep mode)
to help conserve battery life after it has been included in a ZWave network. The
ZWave radio supports beaming. It allows other devices in the network to wake up
the ZWave thermostat, accept commands, and then go back to sleep.
• If you need the thermostat to operate AOS mode (always listening mode) to
act as signal repeater and to increase network reliability, you need to ask your
professional installer to power the thermostat by 24 VAC.

network but the ZWave signal is lost, or
is included but AC power is lost (battery
used as backup). In this case, ZWave
radio is turned off to preserve battery life.
AC power must be restored or you have to
change the power mode. It can be done via
excluding thermostat from ZWave network
and including again in battery power mode
where batteries are used as main power
source. You can check the actual power
mode in the thermostat

Battery replacement
Batteries are optional (to provide backup power)
if your thermostat was wired to run on 24 VAC
power when installed. If your thermostat was
wired to run on 24 VAC power, then batteries are
NOT required.
Install fresh batteries immediately when the low
battery alert appears. The alert appears about
two months before the batteries are depleted.
Even if the low battery alert does not appear, you
should replace batteries once a year, or before
leaving home for more than a month.
If batteries are inserted within two minutes, the
time and day will not have to be reset. All other
settings are permanently stored in memory, and
do not require battery power.
NOTES:
• When replacing batteries, alkaline batteries
are recommended.
• When the battery power is low, the
thermostat’s backlight is disabled to save
battery power.
• When battery power is critically low, only the
alert icon and the battery icon are displayed,
and the thermostat cannot control your
HVAC system. Batteries must be replaced
immediately.
When the low battery alert appears,
press gently to loosen the thermostat
and then carefully pull it from the
wall mount.
Insert fresh alkaline AA batteries and
reinstall thermostat. Match the polar-
ity of the batteries with the
+ / – marks inside the battery com-
partment.

Alerts and maintenance reminders
The T6 Pro ZWave thermostat comes with a set of Smart Alerts that helps keep your
heating and cooling system running correctly and efficiently. If Smart Alerts are set up
by your HVAC professional, you can get reminders when it’s time to change the filter
and when your system is not running correctly.
Non-critical alerts and maintenance reminders can be snoozed for up to 7 days and/
or dismissed. Some critical alerts cannot be snoozed or dismissed as your heating or
cooling system may require service.
