GETTING STARTED
Your safety is very important. Care should be taken to review and completely understand the
installation instructions before installing and wiring the PowerShift thermostat.
A basic understanding of electrical and HVAC systems is required to properly install this
thermostat. If you have difculty following the directions, you should not proceed.
Please call Customer Care to schedule a professional installation.
By selecting the self installation option, it is the users responsibility to ensure that
the thermostat is installed safely and properly. NV Energy will not be liable for
any damages caused by failure to comply with the installation instructions.

The PowerShift Smart Thermostat requires a 24 Volt AC (24 VAC) Common Wire (C/X Wire) to supply power. If your existing thermostat is not powered
by 24 VAC, you may have to connect the Common Wire at the HVAC unit. Follow the instructions below to determine if your home has the required 24
VAC Common Wire.
Determine if your current system is using
24VAC Common Wire
Remove the existing thermostat cover from the wall plate (refer to your
thermostat manual if necessary)
Page 1

Visually inspect wire terminals to locate terminals “C or X” and “R,”
“RH” or “RC”
Determine if the Common Wire (typically blue wire, but not always) is
present and connected to the C terminal:
If Common Wire is connected to C or X terminal, you likely have
24 VAC power available
If your thermostat does not have a Common Wire connected to C
or X terminal or if you have unused wires in the thermostat wire
bundle, test the voltage of unused wires (typically blue wire) to
determine if there is 24 VAC power available
Using a volt meter, touch one voltmeter lead to the metal screw of the
C or X terminal and the other lead to R, RH, or RC terminal. RC RH W Y2 Y GC

Voltage readings of around 24V (between 24 to 30 VAC)
means there is power available at the C terminal – proceed
to Step 1 to remove your old thermostat
Voltage readings of around 0V (below 18 VAC) means the
Common Wire is not connected – visit
nvenergy.com/powershift/selnstallguide for additional
instructions on how to connect the 24VAC Common Wire at
the HVAC unit
If you can't identify the Common Wire, please visit
nvenergy.com/powershift/selnstallguide for further
instructions.
If you determine that the C/X Wire is not connected and are not
comfortable proceeding, please call 855-676-9373 to schedule a
professional installation.
1 REMOVE OLD THERMOSTAT
STEP
Turn off electricity to the HVAC system
CAUTION
It is important to verify there is no voltage at the wall.
Switch OFF power to heating and cooling equipment Locate correct
breaker(s); typically labeled A/C, FAU, or HVAC.
No voltage should be present at the thermostat
Conrm using a volt meter, touch one voltmeter lead to the
metal screw of the C or X terminal and the other lead to R, RH,
or RC terminal.
Voltage readings of around 24V means incorrect breaker has
been turned off. Switch OFF main breaker

Label Wires to match terminal name
CAUTION
DO NOT remove wires from existing thermostat until
each wire is labeled. There is no standard color
code. Ignore the color of the wires and label
according to the terminal each wire is connected to.
Wire Labels (included)
Take a picture of your existing thermostat base plate
with wires still connected to the wall plate or make a
note of which wires are connected to which terminal.
Keep this with your old thermostat in case you need to
replace in the future.
Locate wire labels provided in box with the new
PowerShift thermostat
Identify and attach labels to each wire of your
existing thermostat according to the terminal it is
screwed into. Make sure all your wires labeled
before proceeding
If you had to connect a new 24 VAC common wire,
you will use the “C/X” label on that wire

Disconnect and remove your old
thermostat from the wall
Depending on the style of your thermostat, use a
screwdriver, loosen screws of wire terminals once
labeled and disconnect wires from the wall plate
Remove all screws attaching the wall plate to the
wall and remove wall plate. Make sure the wires
do not slip back into the wall

2 INSTALL POWERSHIFT SMART THERMOSTAT
STEP
Mount PowerShift wall plate
Separate faceplate and wall plate of the PowerShift
thermostat by by pulling straight off
Hold the thermostat base plate against the wall, with the
wires coming through the center opening, above terminal
block.
Mount wallplate to wall with hardware provided. Use level and
drill with 3/16 in. drill bit if necessary
A beauty plate may be required to cover any visible holes from
previous thermostat. Contact 855-676-9373 to request beauty
plate, if needed before beginning installation.
Connect Wires to matching terminal
Insert the thermostat wires from the wall through the opening in the
PowerShift thermostat wallplate. Connect exposed end of correct
wires to matching screw terminals as labeled in Step 1
Tighten the terminal screw until each wire is secure enough to
lightly pull on without coming loose. Do not over-tighten, this may
cut the wire.

If you have just single R wire, you can use either RH or RC terminal
and leave the wire jumper-clip in place. If you have separate wires
labeled RH and RC at the wall you need to remove the wire
jumper-clip between these 2 terminals on the PowerShift
thermostat wallplate.
IMPORTANT
For Heat Pump Congurations
If you have O/B wire, you must check wire information on Terminal
Reference page 8.
Attach thermostat faceplate
& turn on electricity to HVAC system
Attach thermostat faceplate to wallplate by snapping into place.
You may need to gently push wire -bundle against wall to attach
the faceplate properly
Page 4

With all the wires connected (including the C/X wire), and the
thermostat securely attached to the wall, it is time to turn the AC
power back on. Turn the breaker to the ON position at the breaker
panel.
ON OFF
STEP 3 CONNECT POWERSHIFT GATEWAY
The PowerShift gateway device must be connected to your Internet router to enable the PowerShift system to work properly.
A Connect the provided Ethernet cable between the
gateway Ethernet port and any available port of your
home router.
B Connect the provided 5VDC power supply between the
gateway and a 120 VAC power source that will always stay
powered on.
Startup sequence
After plugging in the device the three LEDs at the top of gateway
will gradually turn solid green.

4 CHECK HVAC & TEST THERMOSTAT
STEP
Check that power is available to the thermostat
The PowerShift thermostat display will show the date, time, HVAC mode,
indoor temperature and setpoint if powered on. Pressing any button will
activate the screen.
If power is not evident, check for the following:
The Forced Air Unit/FAU breaker is turned back to the ON
position. To reset the breaker if tripped, turn the breaker to
the OFF position, then back to the ON position
Check that the correct 24VAC wires are connected to the
RC/RH and C terminals
Test the thermostat cooling mode
To activate cooling mode on the PowerShift thermostat, turn to cooling mode by pressing Menu->Mode->Cool.
On the home screen, press the down arrow until the cool setpoint is a few degrees lower than the indoor temperature.
Wait for the system to turn on, which could take up to 5 minutes.
Once the system is on, check any air vent for cool air coming out.
Once cooling system is conrmed to be functioning, adjust to desired setpoint close to the indoor temperature.
Your PowerShift thermostat will run on a default Cooling temperature program until you activate your account through the PowerShift portal.

Test the thermostat heating mode
To activate heating mode on the PowerShift thermostat, turn to heating mode by pressing Menu->Mode->Heat.
On the home screen, press the up arrow until the heat setpoint is a few degrees higher than the indoor temperature.
Wait for the system to turn on, which could take up to 5 minutes.
Once the system is on, check any air vent for warm air coming out.
Once heating system is conrmed to be functioning, adjust to desired setpoint close to the indoor temperature.
Your PowerShift thermostat will run on a default Heating temperature program until you activate your account through the PowerShift portal.
