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 o the 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.

EXISTING THERMOSTAT TERMINALS

LABEL THE WIRES TO MATCH THE OLD THERMOSTAT TERMINAL MARKINGS

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
C	BLUE	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: Environment Canada and Disposing of Mercury Products at: hƩps://www.ec.gc.ca/mercure- mercury/default.asp?lang=En&n=F111AAC6-1.

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.

Single and Dual Transformer Systems (Split Systems)

HVAC systems may have one or two transformers. The “R” wire connects di erently 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.
