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

5. Raise all of the levers on the terminals you will be using. Heat  
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,  
remove it now. It is located underneath the wire holes, between

Preparation  
To ensure wires do not fall back into  
the wall hole, you may tape them  
to the wall, or wrap them around a  
pencil.

Gathering Tools and Warnings  
6. If one of the terminals you need has a tab in front of it, use  
your finger to break the tab away. Figure 9.  
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:  
Y2  
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)  
C
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.

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.  
R, V  
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.  
Y2  
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.

Figure 3b.  
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.

Mounting the Wallplate  
8. Before mounting the thermostat onto the mounting plate, turn it  
over and find the 2 switches located on the circuit board next  
to the battery compartment.  
1. Remove the mounting plate by pulling it straight off the back of  
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  
or a heat pump. “Gas/Oil” will be used if you have gas or oil  
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.  
Gas  
Oil  
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  
the wallplate. Look for any additional screws, tabs, or locking  
devices to remove the wallplate. See Figure 1. If you are still  
unable to find the terminals for the wires, it may be necessary  
to contact the manufacturer of the original thermostat.

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 page 10 of your owners manual to continue setup,  
scheduling, and daily use.

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 mounting plate Figure 7., then install  
Figure 1.  
Labeling Your Wires  
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 thermostats 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.
