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 thermostat is included in ZWave network it typically follows the setting on your
ZWave controller. If you adjust the temperature setpoint, it overrides the current
setpoint until away state or new temperature setpoint is received from ZWave
controller. Setting of Hold until time and Permanent hold (see below) will not be
available on the thermostat screen.
If the thermostat is not included in the ZWave network and the thermostat is
following time based schedule, you can set what time the new temperature setpoint
will be held until or you can hold the new setpoint permanently.
There are several scheduling options available for the thermostat. For more
information go to page 12.
Program schedule override (temporary)
1 Touch or on the thermostat home
screen to set your desired temperature. Hold
Until will appear together with the time the
hold will end.
2 To change when the hold will end, touch the
time and wait until the time starts blinking.
Then, touch or to set when you want
the hold to end. Touch Hold Until once more
to confirm changes and return to the home
screen.
After the hold period ends, the thermostat will
automatically return to the program schedule. If
you want to cancel the hold, touch Hold Until and
then touch Run Schedule.
Program schedule override (perma-

To cycle through the available modes, touch Mode
on the thermostat home screen and select the
appropriate mode for your desired temperature.
• Heat: Controls the heating system.
• Cool: Controls the cooling system.
• Off: Turns the heating and cooling systems
off.
• Auto: When enabled, the thermostat will
automatically use heating or cooling to reach
the desired temperature.
• Em Heat: Controls auxiliary or emergency
heat; only available on systems with a heat
pump.
Notes:
• Em Heat and Auto modes may not appear
on the thermostat screen depending on your
equipment and how your thermostat was
installed.
• Em Heat is only available for heat pump
systems. The thermostat must also be
configured to control a heat pump and an
auxiliary/emergency heat stage.
• When Auto mode is selected, Auto Chg. On

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.

ZWave connection status is located in the
upper-right corner of the screen.
• Thermostat is included and connected to a
ZWave network.
• Thermostat is excluded from a ZWave
network.
• Thermostat is either included in a ZWave
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
MENU/DEVICE INFO.
