Introduction
The Honeywell T6 Pro ZWave Programmable Thermostat is a ZWave Plus certi-
fied thermostat capable of controlling up to three heat and two cool stages of heat
pump, (incl. dual fuel heat pump systems) and up to two heat and two cool stages of
conventional system (3H/2C HP, 2H/2C Conv.) It also measures, displays and
reports % indoor relative humidity; however, this model does not control humidifica-
tion equipment.
It is one of the easiest smart thermostats to install and is controllable by all ZWave
compliant controllers that have the control capability for "Thermostat" devices.
When integrated with the app that controls your ZWave controller, it lets you pro-
gram and control your home’s HVAC system as well as controlling other ZWave
devices connected to the same ZWave controller.
Because the thermostat is battery-powered, low-voltage integrators
can easily connect the thermostat to most HVAC systems. Optional
24 VAC powering via “C” or common wire is also available, if desired.
CAUTION
• We strongly recommend that installation is performed by a trained HVAC
technician.
• Read the enclosed instructions carefully before installing the new
Honeywell T6 Pro ZWave Programmable Thermostat.
• ELECTRICAL HAZARD: Can cause electrical shock or equipment damage.
Disconnect power before beginning installation.
• To prevent abnormal operation, it is highly recommended to configure
the installer setup and set the thermostat to correct HVAC system before
including the thermostat to ZWave network. If the configuration must
be changed, first EXCLUDE the thermostat from the network, change
the thermostat configuration, and INCLUDE the thermostat back to the
network.
• Before disconnecting wires from the existing thermostat, label the wires
with the terminal markings from the old thermostat and record them. Take
a picture of the old wiring.
• Use 3 new AA batteries in the thermostat.

Wiring UWP
Push down on the tabs to put the wires into the
inner holes of their corresponding terminals on
the UWP (one wire per terminal) until they are
firmly in place. Gently tug on the wires to verify
they are secure. If you need to release the wires
again, push down the terminal tabs on the sides
of the UWP.
This wiring is just an example,
yours may vary.

Power options
Insert Rand Cwires into
designated terminals for primary
AC power (C terminal is optional
if batteries are installed, but it is
recommended). Remove wires by
depressing the terminal tabs. Insert 3 AA batteries for primary or
backup power. Match the polarity of the
batteries with the + / – marks inside the
battery compartment.
NOTES:
• The T6 Pro ZWave thermostat works in battery mode or normal power mode
based on its power source. The ZWave power mode can only be changed when
the thermostat is NOT included in a ZWave network. You can check the power
mode in the thermostat menu under MENU/DEVICE INFO.
• If a C wire is not used or present, 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 in AOS mode (always listening mode)
to act as signal repeater and to increase network reliability, you need to power
the thermostat by 24 VAC. The AOS mode information is provided via Node
Information Frame (NIF).

** The THP9045A1023 or THP9045A1098 Wire Saver Module can be used on heat/
cool systems when you only have four wires at the thermostat, and you need a
fifth wire for a common wire. Use the K terminal in place of the Y and G terminals
on conventional or heat pump systems to provide control of the fan and the
compressor through a single wire—the unused wire then becomes your common
wire. See THP9045 instructions for more information.
Set R Slider Tab.
• Use built-in jumper (R Slider Tab)
to differentiate between one or two
transformer systems.
• If there is only one R wire, and it is
connected to the R, Rc, or RH terminal, set
the slider to the up position (1 wire).
• If there is one wire connected to the R
terminal and one wire connected to the Rc
terminal, set the slider to the down position
(2 wires).
NOTE: Slider Tabs for U terminals should be
left in place for other thermostat models.
