Thermostat features
The 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.
The thermostat can be operated in any ZWave network together with other ZWave
certified devices from other manufacturers. All non-battery operated ZWave devices
(nodes) within the network will act as repeaters regardless of manufacturer to increase
reliability of the network. 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.
Flexible scheduling: The thermostat is fully programmable when not included into
a ZWave network. Each day can be programmed for different heating and cooling
settings in 4 unique periods (Wake, Away, Home, Sleep). The thermostat scheduling
options available differ depending on whether the thermostat is included or excluded
from ZWave network, on capability of your ZWave controller and app to program
thermostat.
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. (Available only if the local thermostat schedule is enabled.)
Power method: Designed for battery operation (3 x AA batteries) or for 24 VAC power
operation (via a “C” or common wire).
SmartStart: (TH6320ZW2007 model only). After the initial setup and time/date
have been set, the TH6320ZW2007 thermostat will initiate SmartStart. Icon in upper
right of display will flash. Thermostat stays in SmartStart mode indefinitely until it is
included in a ZWave network.
Identify thermostat: (TH6320ZW2007 only). If the thermostat is included in a ZWave
Network. You can choose to identify the thermostat via ZWave app. Backlight will
flash. Touching display while flashing will stop Identify mode. This is helpful when
multiple thermostats are on the same ZWave Network.
Excluding thermostat: If the thermostat is connected to a ZWave network that you
wish to remove it from, select "Menu". Then touch the right arrow until ZWave network
is shown. Touch "select". The display should show "exclude" if it is currently connected
to a ZWave network. Touch select to exclude the thermostat from the network.

If the thermostat is included in ZWave network it typically follows the setting on your
ZWave controller. If you adjust the temperature setting, it overrides the current setting
until new state (eg. Home/Away) and/or the new temperature setting is received from
ZWave controller. Setting of Hold until time and Permanent hold (see below) will not
be available on the thermostat screen at this time.
There are several scheduling options available for the thermostat. For more
information, see "Scheduling options" on page 12.
If the thermostat is not included in ZWave network and the thermostat is following
local time based schedule only, you can set what time the new temperature setting will
be held until or you can hold the new temperature setting permanently.

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.

TH6320ZW2003 model only. TH6320ZW2007
model has SmartStart and will be in the INCLUDE
MODE as soon as the thermostat is powered and
configured for system type.*
To add to include or remove to 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. If this
happens, position the thermostat closer to the ZWave controller and repeat the
inclusion procedure.
• 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:
• Once the thermostat is included into the ZWave network, it assumes to be
programmed from your ZWave controller and the program schedule on the
thermostat is turned OFF by default. If the thermostat is not included into the
ZWave network, then this thermostat will function as normal programmable
thermostat. For more information, see "Scheduling options" on page 12.
• 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 adding the thermostat for inclusion or removing for exclusion from
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.
* If using the TH6320ZW2007 with a ZWave network that doesn't have SmartStart,
select MENU, then ZWAVE SETUP, then START INCLUDING.

ZWave connection status is located in the upper-right
corner of the screen.
• Solid icon. Thermostat is included and connected
to a ZWave network.
• Flashing Icon. (TH6320ZW2007 model only.)
Thermostat is in the INCLUDE MODE using
SmartStart. This occurs after initial setup and
time and date are set. Include mode shown on page 9.
• TH6320ZW2003 model only. 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.
