4. Check the charts on the back of this sheet and identify your
system type. They are divided by Conventional and Heat Pump
installations.

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.
Not all terminals will be used, this will
be determined by your system type.

Pump Installation labels are located on the left of the terminal
blocks on the mounting plate and Conventional labels are
on the right. If your installation does not call for the jumper,

This thermostat is compatible with most conventional oil, gas,
electric, hot water systems, single stage, and multi-stage heat
pumps. This thermostat will not control line voltage systems.
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:

Note: Only break tabs you know you will be using. Double
check your wiring configuration and make sure you are familiar
with the terminals you will be using.
You will need the following tools to complete your installation:
•Phillips Screwdriver (#2)

A
Jumper
Levers
•Two 1.5V (AA) size alkaline batteries
Figure 3a.
Heat Pump
Take note of these warnings and cautions before
proceeding:
•Only 1 reversing valve is needed
to run a heat pump. If both “O”
and “B” are present, “B” may be a
common wire.
RH
•Read all installation instructions before beginning installation!
If you still need assistance after reading this manual, call our
Technical Support at 1-888-830-1326.

•Often, 2-wire heat only systems do
not have terminal labels. Connect 1
wire to the Rh terminal and the other
to W.

•Do not disconnect the wires from your old
thermostat until all wires have been properly
labeled. You must label all wires properly because
wire color may not indicate the function of the wire.

•If you have a 3-wire hot water
system, the damper valve control
wire will be labeled and attached to
the “A” terminal.
Tabs
•All wiring must be done in accordance with local code and
ordinances.
•Always turn power off to your furnace/compressor before 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.
Figure 9.
•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.
7. Insert the bare end of each wire all the way into the appropriate
hole in the terminal block that matches the wire label then
lower the lever. This will lock each of the wires in place. Tuck
excess wire back into wall after they have been locked in the
mounting plate.

•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.

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.

over and find the 2 switches located on the circuit board next
to the battery compartment.

9. Set the system switch to “Conv” if you have a conventional
HVAC system or “HP” if you have a heat pump system. Set the
furnace type to “Elc” if you have an electric convention system
Note: Conventional systems use the compressor for air
conditioning and a separate furnace for heat. Heat pump systems
use the compressor for both heating and cooling.

1. Turn off power to your compressor and furnace.
2. Remove the cover to your existing thermostat. Some thermostats
may have screws or other locking devices that must first be
removed. Once the wallplate is exposed, locate the wire
terminals and try to identify the wire designations. If the wire
terminals are not visible, they may be connected to the back of
to contact the manufacturer of the original thermostat.

Labeling Your Wires
to keep a record of your old thermostat’s wiring configuration
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.
