Model Number(s): YTH8320ZW1007/U Thermostats / Leviton 
VRC0P-1LW (+3) RS-232 Adapter 
Minimum Core Module Version: g! 5.8 
Document Revision Date: 2/15/2013 
OVERVIEW AND SUPPORTED FEATURES 
The Honeywell YTH8320ZW1007/U thermostats are wireless Z-Wave thermostats capable of controlling 
gas, oil, electric heat with air conditioning, warm air, hot water, high efficiency furnaces, heat pumps, 
steam , gravity, heat only, heat only with fan, cool only and 750mV heating systems.  The 
YTH8320ZW1007/U thermostats are remote controllable over Z-Wave 900mhz wireless mesh networks 
via the use of a Z-Wave RS-232 adapter, enabling 2-way control and feedback from g!.  The g! system 
supports up to 16 wireless thermostats. 
Note: Z-Wave RF operates at 900MHz.  Any other devices operating on the same frequency may cause 
interference and need to be removed.  Leviton recommends the system in installations of 7500 square 
feet or less and installing devices typically no more than 30 feet apart.  Please refer to the Leviton Vizia 
RF Systems Guide (www.ViziaRF.com) for other installation considerations and details on proper setup 
of the Z-Wave networks.  Additional information can be found at www.z-wave.com. 
THE YTH8320ZW1007/U DRIVER SUPPORTS THE FOLLOWING FEATURES: 
Auto Discovery: Thermostats may be auto-detected and added into g! 
Decimal Temperature Control: g! Core module 5.5 added support for decimal temperature display.  
Honeywell’s YTH8320ZW1007/U thermostat set points can be set to .5 degree increments in Celsius 
mode only.  Feedback on the g! UI’s is in .5 degree increments for Celsius mode. 
History View: The history view shows the inside temperature, outside temperature, unit run times, and 
cooling and heating set points. 
Mode Control: The climate system can be set to run in the following heating and cooling modes: Heat 
only, Cool only, Auto, Off or EHeat (Heat Pump Only).  Fan Modes: On, Auto, Circulate 
Schedule Control: Scheduling is supported from the Viewer.  The YTH8320ZW1007/U Built-in Schedule 
must be disabled to use g! scheduling. 
Shared Z-Wave Network: A single Leviton Vizia RF Z-Wave network may contain Door Locks, 
Thermostats, and Lights.  All three may be controlled over a single RS-232 Z-Wave adapter.  See the 
appropriate Z-Wave Door Lock and Z-Wave Lighting Integration Notes for details. 
Temperature Control: Temperature control can be managed by schedules tied to house modes or by 
manual control based on time (Timed Temporary Hold, Temporary Hold and Permanent Hold). 
T
HE YTH8320ZW1007/U DRIVER DOES NOT SUPPORT THE FOLLOWING FEATURES: 
Any feature not specifically noted as “supported” is not supported. 
Name Detection: All thermostats will populate during auto-discovery with their Z-Wave node number as 
their name.  Thermostat names do not read into g! at this time. 
Remote Sensors: The YTH8320ZW1007/U thermostat does not support remote sensors.

INSTALLATION OVERVIEW 
1.  Install the YTH8320ZW1007/U thermostats and wire HVAC according to standard Honeywell 
YTH8320ZW1007/U documentation. 
2.  Test the thermostat and climate system to ensure that the thermostats correctly turn on the 
appropriate heating or cooling equipment, and open or close the appropriate valves / dampers. 
3.  Install a Leviton VRC0P-1LW (+3) RS-232 Z-Wave adapter in a location convenient for both a serial 
run to the g! Controller and within range of other Z-Wave devices. 
Note: Be sure that the “+3” notation is present on the back of the VRC0P-1LW.  (See the Leviton 
application note for additional information: http://communities.leviton.com/docs/DOC-2392). 
4.  Run a Cat-5 or serial cable to the location of the Z-Wave RS-232 location. 
5.  Using a Primary Controller, such as a programming remote (ex. Leviton VRCPG), ControlThink’s 
ThinkEssentials or Leviton’s Vizia RF+ Installer Tool (v1.1.0.0) create a Z-Wave network and add 
thermostats and the RS-232 adapter according to standard procedures. 
Important! Disconnect the g! system from the VRC0P controller when any Z-Wave network 
configuration is occurring. 
6.  Connect the Serial Cabling to the Z-Wave RS-232 adapter electrically.  See the wiring diagrams. 
7. Configure g! for the thermostats and confirm communication between the thermostats and the g! 
controller. 
8.  Test the system by changing the set points, modes and schedules on the viewer and various 
thermostats, confirming that the various components in the system respond as expected. 
Z-W
AVE REPEATERS 
Many Z-Wave devices function as repeaters, meaning an incoming signal can be passed to another Z-
Wave device within range.  The maximum distance a signal can be sent from one Z-Wave device to 
another varies depending on the brand/model of the device used.  See the manufacturer’s 
documentation for the devices you intend to use for specifics. 
The signal can be extended from the controller to the device being controlled by a maximum of four 
passes, known as “hops.”  (From the controller to the first device, the first device to the second, the 
second device to the third and from the third device to the one actually being sent the signal.) 
Depending on the network configuration, occasionally it may be necessary to manually program the 
“hops” to optimize reliability.  Refer to the documentation that came with your specific programming 
tool for details. 
Note: Because Z-Wave door locks require repeaters that are “beaming-compatible” and that support 
beaming of encrypted signals we recommend using only repeaters (lamp modules, switches, etc.) that 
support these features if door locks will be a part of the installation.  See the manufacturer’s 
documentation for the devices you intend to use for specifics. 
NOTES REGARDING THE TRACKING OF Z-WAVE DEVICES: 
In general g! keeps track of the states of all of the Z-Wave Network Devices; however there is latency in 
the reporting back of the devices from the Z-Wave network.  The result is that g! updates its states as the 
devices report back.  This is evident when watching the viewer interface after a change is made at the 
device.  The viewer controls will update sequentially over a few seconds (or more on larger systems) as 
the devices report their states.

Z-WAVE NETWORK PROGRAMMING 
Program the Z-Wave according to standard procedures.  Regardless of device function, the basic setup 
of Z-Wave networks is the same.  Various limitations may be imposed based on the programming tool 
used.  Refer to the documentation that came with your specific programming tool for details. 
Typically a Z-Wave network is programmed using its Programmer/Remote Control (such as the Leviton 
VRCPG-BSG remote, ThinkEssentials Software or Vizia RF+ Installer Tool) to enroll / include devices in 
the Z-Wave Network.  The methods for using the VRCPG, ThinkEssentials and Vizia RF+ Installer Tool 
are detailed below.  Note that these instructions assume you are familiar with Z-Wave programming 
concepts.  If you require further detail or clarification, you may wish to see Leviton Vizia RF 
(www.ViziaRF.com), or Honeywell YTH8320ZW1007/U documentation / technical support for assistance. 
Important!  Programming using the Leviton VRCPG-BSG Remote is NOT supported for 
thermostats when Z-Wave locks are to be included in the system. 
While the VRCPG-BSG does allow you to enroll locks in a Z-Wave network it does not allow you to 
associate the locks with the VRC0P module. 
P
ROGRAMMING USING THE LEVITON VRCPG-BSG REMOTE: 
Setup steps below are created using a VRCPG-BSG remote.  Your steps may vary somewhat if your

TESTING THE Z-WAVE SYSTEM 
On occasion it may be necessary to test the Z-Wave system “outside” of the g! interface to verify 
communication between the thermostats and the controller (the VRC0P-1LW).  The following steps are 
intended to provide a method to test the basic communication status of the Z-Wave network. 
1.  Complete your Z-Wave network set-up as described above, ensuring all thermostats and 
controllers have been added to the network. 
2.  Connect a serial cable from your computer to the VRC0P-1LW’s RJ-11 to DB9 cable.  Use a USB 
to Serial adapter if required. 
3.  Set up a terminal program (ex: HyperTerminal) with the following settings: 
a.  9600 baud; 8 data bits; No parity; 1 stop bit; Flow Control – None 
b.  ASCII Sending Set Up 
i.  Send line ends with line feeds 
ii.  Echo typed characters locally 
4.  Send test commands to verify correct operation: 
Note: Terminal programs other than HyperTerminal may display differently.  The important thing 
is that the “
