Wiring

Typical Wiring for Standard Gas/Electric HVAC System

Typical Wiring for Heat Pump HVAC System

Thermostat Power
The thermostat can be powered by either 24VAC from the HVAC system or from four (4) type AA internal batteries. 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 batteries are not required. If there is no common wire, batteries 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).
Battery Power
Powering the thermostat from batteries does not require a “C” wire connection. DO NOT install batteries if the thermostat is powered by 24VAC. They are not required for backup. If the thermostat is powered by batteries, the thermostat will operate for approximately (2) two years on four (4) AA Alkaline batteries depending on the frequency of user operations and backlight operation. Always use Alkaline batteries and replace in complete sets of four (4) at a me.
Z-Wave Operation when Battery Powered

IMPORTANT: If the thermostat is installed on a Z-Wave network, while it is battery-powered, it will NOT work as a Z-Wave repeater.
CAUTION: Do not install batteries and temporarily power the thermostat from 24VAC to include onto a Z-Wave network. Shortened battery life may occur when 24VAC power is removed

Remove Existing Thermostat

Turn off the power to the thermostat. This is usually done at the heating/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 existing thermostat wires with the wiring labels included according to the terminal markings. Some installations may have additional wires not shown in this example illustration. 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 the 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

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 existing thermostat is a mercury-containing device, it must be disposed of in compliance with federal, state, and local regulations. Many states and /or local agencies have collection/exchange programs or hazardous waste collected programs for mercury-containing devices. For more information, see the U.S. Environmental Protection Agency website at:http://www.epa.gov/osw/hazard/wastetypes/universal/mce.htm For Canada: Environment Canada and Disposing of Mercury Products at: https://www.ec.gc.ca/mercuremercury/default.asp?lang=En&n=F111AAC6-1.

Install the Back Panel
Remove the back panel of the thermostat by pushing down the thumb tab on the bottom of the body.
Figure 3. Removing the back panel of thermostat.

Mount the thermostat back panel on the wall (See Figure 4).

Use the two (2) wall anchors and two (2) Phillips screws (provided) to mount the back panel.
Level as needed.

Figure 4. Mounting the Back Panel

Standard HVAC System Connections

NOTE: For typical connections 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 connections. The lower label shows HEAT PUMP HVAC terminal connections.

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 connecting the wires.

Dual Transformer Systems
For HVAC systems that have separate heating and cooling systems, each with their own 24VAC transformers, there will be an “R” wire from the heating 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

IMPORTANT! FOR SEPARATE RC/RH SYSTEMS, THE INTERNAL RC=RH JUMPER MUST BE CUT ON THE BACK OF THE THERMOSTAT’S PRINTED CIRCUIT BOARD— (See Figure 8).

Figure 8. Internal RC=RH Jumper

Heat Pump HVAC System Connections

NOTE: For typical connections to a Heat Pump HVAC system, refer to the diagram on Page 3. The terminals on the back panel have two sets of labels. The lower label shows HEAT PUMP HVAC terminal connections. The upper label shows the STANDARD HVAC terminal connections

Thermostat Setup Menus

The thermostat must be set for the correct HVAC system type for proper operation.
Preset HVAC System settings

The thermostat is preset for the following typical HVAC system configuration:

HVAC system type: Standard gas/electric
HVAC fan type: Gas heat
HVAC heating 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 configuration other than the preset settings change the settings in the SYSTEM setup menu to match the HVAC system.

NOTE: To conserve battery life, the thermostat backlight turns off after a short me of no activity. The first press of any button turns on the backlight (but does not initiate any action). Press the button again to initiate the action desired. If the backlight is already on, button presses work with the first press.

Wait Mode
The thermostat has a Minimum of Time (MOT) delay after any heating or cooling cycle ends. This delay prevents rapid heating/cooling cycles and also provides “short cycle protection on” for the system compressor. This delay may be not cable when you change a setpoint and it does not respond immediately due to the MOT delay mer preventing the system from restarting. The MOT delays can be adjusted in the Advanced settings menu of the thermostat but there is a minimum of five minutes delay to assure compressor protection.

Minimum Run Time (MRT)
The thermostat has a Minimum Run Time delay after the start of any heating or cooling call. This minimum run time assures even heating 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 satisfy the call until the MRT expires. Changing the Mode to OFF will cancel the MRT and the system will turn off immediately. The MRT can be adjusted in the Advanced Settings menu of the thermostat.

NOTE: The MRT delays are shown by flashing heat or cool icons on the display

Entering Menu Mode

To change the System setup, go to the thermostats Menu Mode and select SYSTEM. From there
Select the correct HVAC settings to match the installation type.
Press and hold the FAN button to enter the Menu Mode. SETUP is the first menu item displayed.

Changeover Type (For Heat Pump HVAC Systems Only)
The changeover (or reversing) valve is used to change from heating to cooling operation. The HVAC system is either a Changeover with Cooling type (O) or a Changeover with Heating type (B). Most are changeover with cooling, which is the default setting.

For Changeover with Cooling systems, select WITH COOL. This is the default setting.
For Changeover with Heating systems, use the buttons to change to WITH HEAT.
Press Select to set.
Press Done to exit.

Not sure what type of Changeover system? Check the existing thermostat connecttions 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 setting accordingly.

NOTE: If heating comes on when cooling is expected or vice versa, switch the “Changeover Type” to the opposite setting.

Z-Wave Installation

Z-Wave controllers from various manufacturers may support the Z-Wave Thermostat General V2 Device class used by the Go Control 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 supporting the thermostat device class):

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 instructions).
Press any button to take the thermostat out of sleep mode.
Press and hold the FAN button for 5 seconds. SETUP will be displayed in the status display line.
Scroll to “Z-Wave” using buttons. Press SELECT.

If Z-Wave does not connect to the controller, WAIT, then FAIL will flash in the status display line.
If the thermostat fails to connect, repeat Steps three (3) thru (7) to re-try connecting.

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 deleting the thermostat from an existing network, refer to the Z-Wave controller instructions.

Inclusion and Exclusion
Inclusion or exclusion is started by putting 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 informaon frame at normal power. Low power inclusion or low power exclusion is not possible.

CAUTION: Do not install batteries and temporarily power the thermostat from 24VAC to include onto a Z-Wave network. Shortened battery life may occur when 24VAC power is removed

For Heat Pump systems only:

“Heat-E” = Emergency heat mode active

Settings the System Mode

System Modes

Off: The system is off. No heating or cooling will come on. If the system was on, it will turn off immediately.
Heat: Only heating will occur.
Cool: Only cooling will occur.
Auto: Heating or cooling will come on according to the heating and cooling setpoints.

The system will automatically switch between heating and cooling modes as needed to maintain the setpoints.

Special Heat Pump Mode: Emergency Heat
An additional system mode, “Heat-E” for Emergency Heat will be displayed if the HVAC System Type is set to Heat Pump. If there is a compressor failure with the Heat Pump system, setting the mode to Emergency Heat will allow the supplemental Aux Heat to come on first whenever there is a call for heating. It also disables the compressor output to prevent further damage to the HVAC system.

CAUTION! Emergency Heat should only be used for emergencies until the HVAC system can be repaired. Running the system in Emergency Heat mode is commonly the most expensive mode since only the electric heat strips are being used instead of the more efficient heat pump compressor\

Setting the Heating or Cooling Temperature Setpoint
To change the setpoint, press the buttons. The screen will switch to the setpoint change screen and show the current setpoint of the current heating or cooling mode. Adjust the setpoint temperature up or down with the buttons.
