WARNING: To avoid electrical shock and to prevent damage to the furnace, air
conditioner, and the thermostat, disconnect the power supply before beginning
work. This can be done at the circuit breaker.
Caution: Your thermostat is a precise instrument, handle it with care:
• Turn off electricity to the HVAC system before installing or servicing the
thermostat or any part of the system.
• Do not turn electricity back on until work is completed.
• Do not short (jumper) across electrical terminals at the control on the furnace
or air conditioner to test the system. This may damage the thermostat.
• All wiring must conform to local codes and ordinances.
This thermostat is designed for use with three AA alkaline batteries and/or 24
VAC C wire (or a 12 to 24 AC or DC source) and millivolt gas systems. Each
thermostat relay load should be limited to 1.0 A; higher amperage may cause
damage to the thermostat.

Tools
You will need a small Phillips screwdriver and a drill with a 3/16-in. (4.8 mm) bit
for wall mounts.
Location
For replacement installations, mount the thermostat in place of the old
thermostat. A new location will require moving your wiring.
For new installations and relocating the thermostat, follow these guidelines:
• Locate the thermostat on an inside wall, about 5 ft. (1.5 m) above the floor,
and in a room that is used often.
• Do not install the thermostat where there are unusual heating conditions,
such as: in direct sunlight; near a lamp, radio, television, radiator register, or
fireplace; near water pipes in a wall; or near a stove on the other side of a
wall.
• Do not locate in unusual cooling conditions, such as on a wall separating an
unheated room; or in a draft from a stairwell, door, or window.
• Do not locate in a damp area. This can lead to corrosion that will shorten
thermostat life.
• Do not locate where air circulation is poor, such as in a corner; in an alcove;
or behind a door.
• Do not install the thermostat until all construction and painting has been
completed.
• This thermostat does not require leveling.
Remove the old unit
Caution: Read the instructions carefully before removing any wiring from the
existing thermostat. Wires must be labeled before they are removed. There is no
standard color code. When removing wires from their terminals, ignore the color
of the wires and label them by the lettered terminal where they are screwed.
Switch off electricity to the heating and cooling systems, and then follow these
instructions.
1. Remove the cover from the old thermostat. Most are snap-on types and
simply pull off. Some have locking screws on the side or front. These must be
loosened. Do not remove wires. Note the letters printed near the terminals.
Attach labels (enclosed) to each wire for identification.
2. Label wires one at a time. You must label all the wires before you proceed.
P/N 1069510 • REV A • ISS 09NOV10 3

3. With all wires labeled, remove them from the old unit. Make sure the wires do
not fall back inside the wall. You can wind them around a pencil to keep them
from falling.
4. Loosen all screws on the old thermostat and remove it from the wall.
Figure 2: Labeling wires
Wiring
Make sure your wires are labeled. This may require you to find the other end
connection for each wire on your heating or air conditioning equipment and read
the label there. See “Wire reference chart” on page 16 for more information on
wire labels from different HVAC system makers.
Note: The thermostat runs on three AA alkaline batteries and/or the C wire if
available. If you do not have a C wire, you can run a new wire from the HVAC or
use a standard 12 to 24 VAC or VDC wall transformer. An external power source
is required when using a radio module.
Note: If you have both RH and RC you need to remove the jumper wire between
these two terminals (see Figure 3 on page 5).
Prepare the wires
Follow these guidelines for safe and secure wire connections:
• You will need at least 2.6 in. of wire for each connection to the thermostat. If
you do not have enough wire, splice additional wire to allow enough slack.
• Terminals accept 16 to 22 AWG wire.
• Fan out wires below the mounting hole (see Figure 3 on page 5).
• Remove insulation 1/8 in. from the tip of each wire (see Figure 3 on page 5).
• When handling, take care not to damage the labels for each wire.

Identify your wiring diagram
Select the reference page with your wiring diagram and set-up information.
• “Two-wire heat, gas millivolt or 24 VAC system (C, W, RH):” on page 11
• “Three-wire heat (C, W, RH, G):” on page 12
• “Four-wire heat/cool (C, W, Y, RH, G)” on page 12
• “Five-wire heat/cool (C, W, Y, RH, RC, G)” on page 13
• “Four-wire heat pump without AUX heat (C, B or O, Y, RH, G):” on page 13

• “Two-stage heat and two-stage cool (C, W2, W, Y, Y2, RH, G):” on page 15
• “Three-wire zoned hot water (W, RH, [A]):” on page 15
The C wire is optional, but preferred for all installation (shown as a dotted line in
the wiring diagrams listed above). Some radio modules will require the 24 VAC C
wire power.
If your combination of wires is not listed, you can use the “Wire reference chart”
on page 16 to determine your connections, contact customer support for help.
Fan out wires with the thermostat below the wall opening so that the C wire is
above the C terminal, the W wire above the W terminal, etc. This allows the
thermostat to fit snug to the wall. Wires will position behind the thermostat and up
over the terminal area. Do not bunch wires behind the thermostat. Feed any
slack back into the wall opening.

Caution: Do not allow wires to touch each other or parts of the thermostat.
Connect your wires
Connect the labeled wires only to a terminal with the same letter label. Insert the
wire in the terminal well and tighten the screw securely.
Note: If you prefer, you can mount the thermostat to the wall first, and then
connect the wires.
The thermostat can be externally powered with a power source rated 12 V to 24
V AC or DC, at 300 ma or greater. If used, connect to the C and RH terminals (no
polarity).
Mount the thermostat to the wall
1. Hold the thermostat against the wall, with the wires coming over the top
above the terminal block. The thermostat will cover the hole in the wall.
Position the thermostat for best appearance.
2. Mark first and drill a 3/16 in. (4.8 mm) hole for the insert at each screw
location, then mount the unit.
3. Attach the thermostat to the wall with the screws provided. If you are
mounting the thermostat to sheet rock or if you are using the old mounting
holes, use the plastic anchors provided.

Install the batteries
Install three AA alkaline batteries (required) following the marked polarity in the
battery compartment. Put the lower battery in negative end first against the
spring, then push the positive end in. Then insert the last two batteries as shown
below.
Figure 7: Battery installation
Special battery warning
• Always replace the batteries as soon as the “Low Batt” flashes. The
thermostat is a battery-powered device. You must be responsible to replace
the batteries before they run out.
• Even if the “Low Batt” indicator does not flash, you should always replace the
batteries at least once a year. Replacing the batteries also helps to prevent
leakage that can corrode and damage the thermostat.
• if you are leaving your home for a month or more, you should replace the
batteries as a precaution against battery failure in your absence.
• Failing to replace the batteries, when necessary could cause the thermostat
to lose power or malfunction. If the thermostat loses power, then the
thermostat will not control the temperature which could result in your HVAC
system not functioning as you intended and lead to possible damage from
overheating or excessive cooling.
• If the thermostat batteries fail with the heat OFF, this could result in no
heat and possible frozen or broken pipes and water damage.
• If the thermostat batteries fail with the cool OFF, this could result in no
cooling and could cause possible damage or excessive temperatures.
• Always use new alkaline batteries.

To complete the installation
Press the Reset button (under the top cover, see Figure 1 on page 2) to
implement the HVAC switch selections.
With all the wires connected, it is time to turn the AC power back on. Do this at
the breaker you used to switch it off. The thermostat will power-up in the OFF
mode. Your thermostat is not configured to operate you HVAC system yet. You
must now configure your thermostat for your HVAC system.
HVAC setup
1. Make sure the thermostat is powered up and the MODE button is set to OFF.
The HVAC selection switches should already be set (see “HVAC selection” on
page 7).
2. With mode in OFF, press the Menu button
3. Press HVAC SETUP on the Menu screen.
4. On the HVAC setup screen, use the +/- icons to select the HVAC number.
The LCD display will show your selection and indicate the number of stages you
have selected. During setup, 2nd stage will blink when both heat and cool have
2nd stages.

If you have a heat pump HVAC system:
Heat pump with AUX heat (Fast Recovery) Select A
Heat pump with AUX heat (Efficient Recovery) Select B
Heat pump no AUX heat Select C
Note: For two-stage systems your thermostat can recover from a temperature
setback in two ways:
• Fast Recovery - this uses your 2nd stage to bring the house to target
temperature. This may use slightly more energy.
• Efficient Recovery - This uses the 2nd stage to bring your house to within a
few degrees of the target temperature and then uses the 1st stage to go the
last bit. (Refer to the Operating Guide for information about setting the
differential). This is more efficient.
Testing the installation
Follow these procedures to verify you have correctly installed the thermostat.
To check the fan (if you have the G wire):
1. Press the FAN button to turn the fan ON.
2. Verify that air is blowing from the system.

setup, and your system still does not operate, contact technical support.
Statement of use
This thermostat can be used with three AA batteries, 24 VAC (C wire), 24 VAC
adapter, heating and cooling systems, and millivolt heating. It cannot be used
with line voltage systems. This thermostat is digital and your desired heat or cool
temperatures can be set on the large touch screen with the +/- buttons. A
minimum 4-minute off time protects the compressor from damage.
This thermostat runs on three AA batteries. The thermostat can be externally
powered with a power source from 12 to 24 VAC or VDC, at 300 mA or greater. If
used, connect to the C and RH terminals (no polarity). The 24 VAC “C” wire is on
the other side of the 24 VAC heating transformer and can be found where the
other thermostat wires connect at the wall or at the furnace. Do not use the
common or ground side of the line voltage.
