This thermostat is compatible with most oil, gas, electric, hot water
systems, single stage, and multi-stage heat pumps. This thermostat
will not control line voltage systems.
Be sure to gather all tools necessary to complete your installation
before removing the old thermostat:
* Phillips Screwdriver
* Two 1.5V (AA) size alkaline batteries
Take note of these warnings and cautions before
proceeding:
* Read all installation instructions before beginning installation!
* Do not disconnect the wires from your old thermostat until all
wires have been properly labeled. You must label all wiring
properly because wire color may not indicate the function of
the wire.
* All wiring must be done in accordance with local code and
ordinances.
* Always turn power off to your furnace/compressor during the
installation process. Failure to do so could result in damage to
your thermostat and/or your heating and cooling system. Do not
restore power until your installation is complete.
* This thermostat is designed for use with 24V AC/millivolt systems
with a maximum of 1 amp. Higher amp or line voltage systems
will cause damage to your system and increase the risk of fire.

Gathering Tools and Warnings 1
Preparation
Old ermostat Removal 1
1. Turn off power to your furnace.
2. Remove the existing cover. Some thermostats may have screws
or other locking devices that must rst be removed. Once the
wallplate is exposed, locate the wire terminals. If the wire
terminals are not visible, they may be connected to the back of
the wallplate. Look for any additional screws, tabs, or locking
devices to remove the wallplate. See Figure 1. If you are still
unable to nd the terminals for the wires, it may be necessary
to contact the manufacturer of the original thermostat.
Warning: Do not remove any wires from the existing thermostat
until you have labeled all wires with the included terminal stickers.
Installation
Labeling Your Wires 2
Use the table in Figure 2. to write down your wire colors and
the letter designations on the old thermostat. This will allow you
to keep a record of your old thermostat’s wiring conguration
should you need to refer to it at a later time. This will also help our
Technical Support Department determine your system type and
proper wiring, should you need to contact them. Wire color does
not indicate the function of the wire, this is being used only to help
determine which wire has what letter designation.
Installation
Mounting the Wallplate 2
After writing down the wire colors
and letters, use the terminal stickers
to label the wires. Figures 3a and
3b will help you depending on
system type; Conventional or Heat
Pump.
To ensure wires do not fall back
into the wall hole, you may tape
them to the wall, or wrap them
around a pencil.
Figure 4. may assist you if your
old thermostat is a heat pump from
one of the listed Manufacturers and
your wire labels do not match. It is
located on the back of this sheet.
These tips will also help you in
wiring:
* Only 1 reversing valve is needed
to run a heat pump. If both “O”
and “B” are present, “B” may be
a common wire.
* Often, 2-wire heat only systems
do not have terminal labels.
Connect 1 wire to the Rh terminal
and the other to W.
* If you have a 3-wire heat only
system, the damper valve control
wire will be labeled and attached
to the “A” terminal.
* If you need further assistance
with wiring, or determining your
system type, you can contact our
Technical Support Department.
See the “Technical Support”
section for information.

1. Remove the backplate by pulling it straight off the back of the
Thermostat. Figure 4.

2. Pull the wires through the back of the mounting plate, ensuring
none of the wire labels are removed. Figure 5.

3. Using a Phillips Screwdriver, Partially install 1 screw into the
top hole of the thermostat. Ensure the thermostat is level using
the bubble level on the backplate Figure 6., then install the
other screw. Tighten both screws until secure. Figure 7.
Figure 10.
4. Check the charts on the back of this sheet and identify your
installation type. They are divided by Conventional and Heat
Pump installations.
5. Raise all of the levers on the backplate you will be using. Heat
Pump Installation labels are located on the left of the terminal
blocks on the backplate and Conventional labels are on the
right. If your installation does not call for the jumper, remove
it now. It is located in the wire holes, between the RH and RC
terminals on the conventional side. Figure 8.
6. If one of the terminals you need has a tab in front of it, use
your nger to break the tab away. Figure 8.
Note: Only break tabs you know you will be using.
7. Insert the bare end of each wire all the way into the appropriate
hole in the front of the terminal block that matches the wire
label then lower the lever. This will lock each of the wires in
place.
Note: Do not insert the wires into the holes in the top of the
mounting block. The wires should be inserted into the front close
to the hole in the mounting plate. See Figure 8.
8. Before mounting the thermostat onto the backplate, turn it over
and nd the 2 switches located on the circuit board next to the
battery compartment.
9. If you have a conventional system, set the system switch to
“Conv” and select your furnace type. Choose “Elec” for electric
based systems, and “Gas” for gas or oil based systems. Select
“HP” if you have a heat pump system and make sure the
furnace type is set to “Elec.” Figure 9.

10. Lay the ribbon across the battery compartment and install 2
(AA) Batteries into the back of the thermostat over it, Figure
10., and snap the thermostat on to the mounting plate. Refer
to “Setup” on page10 of your owner’s manual to continue setup,
scheduling, and daily use.
