GC-TBZ48L
BATTERY POWERED Z-WAVE PLUS THERMOSTAT
INSTALLATION INSTRUCTIONS
The Z-Wave Plus Thermostat (GC-TBZ48L) is a programmable, Z-Wave communicang
thermostat. It can be powered using 24VAC (if both “R”&”C”wires are available at the
thermostat), or using four (4) AA baeries. Using Z-Wave technology, end users have the ability
to use most compable Z-Wave hubs/controllers to operate and animate the thermostat,
configure programming sengs, as well as to display current condions in the home or office.

Thermostat Power
The thermostat can be powered by either 24VAC from the HVAC system or from four (4) type AA
internal baeries. DO NOT use this thermostat for line voltage controls (120/240VAC).
The C Wire
If the 24VAC common wire (usually blue) is present and is connected to 24VAC common at the HVAC
system end, the thermostat can be powered from the HVAC system and baeries are not required. If
there is no common wire, baeries are required.
24VAC Power
Powering the thermostat with 24VAC power requires both the 24VAC “C” common wire (typically a
blue wire) and the 24VAC ”R” return wire (typically a red wire).
BaƩery Power
Powering the thermostat from baeries does not require a “C” wire connecon.
DO NOT install baeries if the thermostat is powered by 24VAC. They are not required for backup.
If the thermostat is powered by baeries, the thermostat will operate for approximately (2) two
years on four (4) AA Alkaline baeries depending on the frequency of user operaons and backlight
operaon. Always use Alkaline baeries and replace in complete sets of four (4) at a me.
Z-Wave OperaƟon when BaƩery Powered
IMPORTANT: If the thermostat is installed on a Z-Wave network, while it is baƩery powered, it will
NOT work as a Z-Wave repeater.
CAUTION: Do not install baeries and temporarily power the thermostat from 24VAC to include onto
a Z-Wave network. Shortened baery life may occur when 24VAC power is removed.

Remove Existing Thermostat
• Turn offthe power to the thermostat. This is usually done at the heang/cooling system or
circuit breaker panel.
• Remove the cover of old thermostat to expose the wiring terminals.
• Take a picture of the wiring terminals and the wires before disconnecting them!
• Mark the exisng thermostat wires with the wiring labels included according to the terminal
markings. Some installaons may have addional wires not shown in this example illustraon.
Y1, Y2, W1, W2, O,B.
• Use the thermostat terminal “names/marking” (not the wiring color) to mark the wires.
• Remove the old thermostat base.
CAUTION: When removing thermostat, don’t let the wires slip into the wall and don’t let the wires
touch each other.
• If the old thermostat was a mercury style thermostat, dispose of it properly as described below.
Figure 2. Label Wire Terminals
NOTE: Taking a picture is critical if problems are encountered. This will allow reinstallation
of the old thermostat and will help with troubleshooting later if needed.
Terminal Typical Wire Color Function
Y YELLOW Cool
W WHITE Heat
G GREEN Fan
R RED 24VAC Return
CBLUE 24V Common (typically BLUE). When the wire is
present, the thermostat can be powered without
baeries. When the wire is absent, the thermostat
must be powered by baeries if 24VAC is present
across the R&C wires
Wiring Colors
While the thermostat terminal markings are intended to match the wire color, (R=RED, G=GREEN,
W=WHITE, Y=YELLOW) be sure to follow the terminal marking when marking the wires, even if the
wire color doesn’t match.
WARNING: If the exisƟng thermostat is a mercury-containing device, it must be disposed
of in compliance with federal, state, and local regulaƟons. Many states and /or local
agencies have collecƟon/exchange programs or hazardous waste collecƟon programs for
mercurycontainingdevices. For more informaƟon, see the U.S. Environmental ProtecƟon
Agencywebsite at:hƩp://www.epa.gov/osw/hazard/wastetypes/universal/mce.htm For Canada:

Install the Back Panel
Remove the back panel of the thermostat by pushing down the thumb tab on the boom of the body.
Figure 3. Removing back panel of thermostat.
Mount the thermostat back panel on the wall (See Figure 4).
1. Use the two (2) wall anchors and two (2) Phillips screws (provided) to mount the back panel.
2. Level as needed.

Standard HVAC System Connections
NOTE: For typical connecons to a Standard HVAC system, refer to the diagram on Page 2.
The terminals on the back panel have two sets of labels. The upper label shows the STANDARD HVAC
terminal connecons. The lower label shows HEAT PUMP HVAC terminal connecons.
Figure 5. Standard HVAC System Terminal Block Labeling
Figure 6. Standard HVAC Systems Terminal Block Connections
Single and Dual Transformer Systems (Split Systems)
HVAC systems may have one or two transformers. The “R” wire connects differently depending on
the system.
Single Transformer System
Most HVAC systems have a single 24VAC transformer. For these systems, there is only one “R”
wire and it can be connected to either the thermostat’s RC or RH terminal as these are internally
jumpered together.
If installing a Standard HVAC system, connect the wires from the HVAC system to the corresponding
terminals on the thermostat back terminal block. Use the table below as a guideline for connecng
the wires.
Wire Terminal
Y Connect to the Y1 terminal
G Connect to the G terminal
R Connect to either RC or RH terminals (Except for Dual Transformer Systems, See Next
Page)
C Connect to the C terminal. C wire (24VAC common) may not be present. If not present,
baeries MUST be installed.
W Connect to the W1 terminal
NOTES: Ensure that the appropriate wires are screwed into the terminal blocks firmly.
Gently pull on the wires to confirm the connecon.
Push all excess wiring back into the wall opening.

Dual Transformer Systems
For HVAC systems that have separate heang and cooling systems, each with their own 24VAC
transformers, there will be an “R” wire from the heang system and an “R” wire from the cooling
system.
For dual transformer systems, connect the “C” wire from the cooling system to the thermostat’s “C”
terminal. DO NOT CONNECT THE “C” WIRE FROM THE HEATING SYSTEM.
Figure 7. Dual Transformer HVAC System Thermostat Terminal Connections
Connect the wires from the HVAC system to the corresponding terminals on the thermostat back
terminal block. Use the table below as a guideline for connecng the wires.
