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:

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.

Thermostat Setup Menus
The thermostat must be setup for the correct HVAC system type for proper operaon.
Preset HVAC System seƫngs
The thermostat is preset for the following typical HVAC system configuraon:
• HVAC system type: Standard gas/electric
• HVAC fan type: Gas heat
• HVAC heang stages: one
• HVAC cooling stages: one
If the thermostat is installed on this type HVAC system, the System Setup does not need to be
changed.
If installed on a Heat Pump HVAC system or any HVAC configuraon other than the preset sengs,
change the sengs in the SYSTEM setup menu to match the HVAC system.
NOTE: To conserve baery life, the thermostat backlight turns offaer a short me of no acvity.
The first press of any buon turns on the backlight (but does not iniate any acon). Press the buon
again to iniate the acon desired. If the backlight is already on, buon presses work with the first
press.
Wait Mode
The thermostat has a Minimum OffTime (MOT) delay aer any heang or cooling cycle ends. This
delay prevents rapid heang/cooling cycles and also provides “short cycle protecon” for the system
compressor. This delay may be noceable when you change a setpoint and it does not respond
immediately due to the MOT delay mer prevenng the system from restarng. The MOT delay me
can be adjusted in the Advanced Sengs menu of the thermostat but there is a minimum of five
minutes delay to assure compressor protecon.
Minimum Run Time (MRT)
The thermostat has a Minimum Run Time delay aer the start of any heang or cooling call. This
minimum run me assures even heang and cooling cycles. The MRT will keep the system on, even
if it reaches the setpoint room temperature, or you change the setpoint to a temperature that would
sasfy the call, unl the MRT expires. Changing the Mode to OFF will cancel the MRT and the system
will turn offimmediately. The MRT can be adjusted in the Advanced Sengs menu of the thermostat.
NOTE: The MRT delays are shown by flashing heat or cool icons on the display.

System Menu
The SYSTEM menu is used to setup the thermostat for the correct HVAC system type. The following
setup opons will be displayed in the text line:
• HVAC System Type: Standard Gas/Electric or Heat Pump
• Fan Type: Gas Heang or Electric Heang
• Changeover Valve Type (for Heat Pump Systems): Changeover with Cooling or with Heang.
To select opons:
• Use the  buons to scroll to the desired seng.
• Press SELECT to change a seng. The current seng for that selecon will be flashing.
• Change the opon with the  buons.
• When the desired opon has been selected, Press SELECT again to save it.
• Then press DONE to exit.
System Type
• For Standard Gas/Electric systems, select STANDARD This is the default seng.
• For Heat Pump systems, press the  buons to change to HEAT PUMP
• Press SELECT to set.
• Press DONE to exit.
Fan Type (For Standard HVAC systems only)
Fan type depends on the heang system type.
• For Gas heat: select GAS. This is the default seng.
• For Electric heat: press the  buons to change to ELECTRIC.
• Press SELECT to set.
• Press DONE to exit.
Changeover Type (For Heat Pump HVAC Systems Only)
The changeover (or reversing) valve is used to change from heang to cooling operaon. The HVAC
system is either a Changeover with Cooling type (O) or Changeover with Heang type (B). Most are
changeover with cooling, which is the default seng.
• For Changeover with Cooling systems, select WITH COOL. This is the default seng.
• For Changeover with Heang systems, use the  buons to change to WITH HEAT.
• Press Select to set.
• Press Done to exit.
Not sure what type Changeover system? Check the exisng thermostat connecons to help
determine this. If the original system had an orange wire connected to an “O” terminal, then this is a
“changeover with cool” system. If there was a brown wire connected to a “B” terminal, then this is a
“change over with heat” system. Set the Changeover seng accordingly.
NOTE: If heating comes on when cooling is expected or vice versa, switch the “Changeover
Type” to the opposite setting.

Z-Wave Plus InstallaƟon
Z-Wave controllers from various manufacturers may support the Z-Wave Thermostat General V2
Device class used by the GoControl Z-WAVE Thermostat. The following procedure will allow the
thermostat to be added to a Z-Wave network.
NOTE: Before adding the thermostat to a Z-Wave Network, check that it does not already belong to
one by viewing the Node ID (ZNID) located in the Thermostat Info screen. An uninstalled thermostat
should show zeros for the Node ID (000). Consult your controller’s user manual for details on
removing a device from a Z-Wave network.
Figure 16. Z-Wave Menu Setup
General Programming Procedure (for controllers supporng the thermostat device class):
1. Set your primary controller to Include, add or Install mode, to add the thermostat as a node on
your network (see your controller’s user manual for detailed instrucons).
2. Press any buon to take thermostat out of sleep mode.
3. Press and hold FAN buon for 5 seconds. SETUP will be displayed in the status display line.
4. Scroll to “Z-Wave” using  buons. Press SELECT.
5. When prompted by your Z-Wave controller, Press the YES buon in the Z-Wave Install screen.
6. Press SELECT (mode buon) to add thermostat to network.
7. Display line should flash WAIT then SUCCESS if Z-Wave connecon is made.
8. If Z-Wave does not connect to controller, WAIT, then FAIL will flash in status display line.
9. If thermostat fails to connect, repeat Steps three (3) thru (7) to re-try connecng.
Your controller will indicate the thermostat was successfully added to its network (see your
controller’s user manual for details). Also, you can check if the thermostat was successfully added
to the network by checking the ZHID (Home ID) and ZNID (Node ID) located in the Thermostat Info
screen.
For other specific tasks such as adding the thermostat to Scenes or Groups, or deleng the thermostat
from an exisng network, refer to the Z-Wave controller instrucons.
Inclusion and Exclusion
Inclusion or exclusion is started by pung the controller into add node or remove node state
and performing the General Programming Procedure outlined above. As part of the process, the
thermostat sends a node informaon frame at normal power. Low power inclusion or low power
exclusion is not possible.
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.
