Thermostat Power
The thermostat can be powered by either 24VAC from the HVAC system or from four (4) type AA
internal ba
Ʃ
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
Ʃ
eries are not required. If
there is no common wire, ba
Ʃ
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).
Ba
Ʃ
ery Power
Powering the thermostat from ba
Ʃ
eries
does not
require a “C” wire connec
Ɵ
on.
DO NOT
install ba
Ʃ
eries if the thermostat is powered by 24VAC. They are not required for backup.
If the thermostat is powered by ba
Ʃ
eries, the thermostat will operate for approximately (2) two
years on four (4) AA Alkaline ba
Ʃ
eries depending on the frequency of user opera
Ɵ
ons and backlight
opera
Ɵ
on. Always use Alkaline ba
Ʃ
eries and replace in complete sets of four (4) at a
Ɵ
me.

NOT work as a Z-Wave repeater.
CAUTION:
Do not install ba

Remove Existing Thermostat
• Turn o
ff
the power to the thermostat. This is usually done at the hea
Ɵ
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
Ɵ
ng thermostat wires with the wiring labels included according to the terminal
markings. Some installa
Ɵ
ons may have addi
Ɵ
onal wires not shown in this example illustra
Ɵ
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.

24V Common (typically BLUE). When the wire is
present, the thermostat can be powered without
ba
Ʃ
eries. When the wire is absent, the thermostat
must be powered by ba
Ʃ
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 exis
Ɵ
ng thermostat is a mercury-containing device, it must be disposed
of in compliance with federal, state, and local regula
Ɵ
ons. Many states and /or local
agencies have collec
Ɵ
on/exchange programs or hazardous waste collec
Ɵ
on programs for
mercurycontainingdevices. For more informa

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 di
ff
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
Ɵ

Thermostat Setup Menus
The thermostat must be setup for the correct HVAC system type for proper opera
Ɵ
on.
Preset HVAC System se
ƫ
ngs
The thermostat is preset for the following typical HVAC system con
fi
gura
Ɵ
on:
• HVAC system type: Standard gas/electric
• HVAC fan type: Gas heat
• HVAC hea
Ɵ
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 con
fi
gura
Ɵ
on other than the preset se
ƫ
ngs,
change the se
ƫ
ngs in the SYSTEM setup menu to match the HVAC system.
NOTE:
To conserve ba
Ʃ
ery life, the thermostat backlight turns o
ff
a
Ō
er a short
Ɵ
me of no ac
Ɵ
vity.
The
fi
rst press of any bu
Ʃ
on turns on the backlight (but does not ini
Ɵ
ate any ac
Ɵ
on). Press the bu
Ʃ
on
again to ini
Ɵ
ate the ac
Ɵ
on desired. If the backlight is already on, bu
Ʃ
on presses work with the
fi
rst
press.
Wait Mode
The thermostat has a Minimum O
ff
Time (MOT) delay a
Ō
er any hea
Ɵ
ng or cooling cycle ends. This
delay prevents rapid hea
Ɵ
ng/cooling cycles and also provides “short cycle protec
Ɵ
on” for the system
compressor. This delay may be no
Ɵ
ceable when you change a setpoint and it does not respond
immediately due to the MOT delay
Ɵ
mer preven
Ɵ
ng the system from restar
Ɵ
ng. The MOT delay
Ɵ
me
can be adjusted in the Advanced Se
ƫ
ngs menu of the thermostat but there is a minimum of
fi
ve
minutes delay to assure compressor protec
Ɵ
on.
Minimum Run Time (MRT)
The thermostat has a Minimum Run Time delay a
Ō
er the start of any hea
Ɵ
ng or cooling call. This
minimum run
Ɵ
me assures even hea
Ɵ
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
Ɵ
sfy the call, un
Ɵ
l the MRT expires. Changing the Mode to OFF will cancel the MRT and the system
will turn o
ff
immediately. The MRT can be adjusted in the Advanced Se
ƫ
ngs menu of the thermostat.
NOTE:
The MRT delays are shown by
fl
ashing heat or cool icons on the display. 12

9. If thermostat fails to connect, repeat Steps three (3) thru (7) to re-try connec
Ɵ
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 speci
fi
c tasks such as adding the thermostat to Scenes or Groups, or dele
Ɵ
ng the thermostat
from an exis
Ɵ
ng network, refer to the Z-Wave controller instruc
Ɵ
ons.
Inclusion and Exclusion
Inclusion or exclusion is started by pu
ƫ
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
Ɵ
on frame at normal power. Low power inclusion or low power
exclusion is not possible.
CAUTION:
Do not install ba
Ʃ
eries and temporarily power the thermostat from 24VAC to include onto
a Z-Wave network. Shortened ba
