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. 
You will need the following tools to complete your installation:
• Phillips Screwdriver (#2)
• Two 1.5V (AA) size alkaline batteries
Take  note  of  these  warnings  and  cautions  before 
proceeding:
• 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.
• 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.
• 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.
• 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

Old ermostat Removal
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 rst 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 nd the terminals for the wires, it may be necessary 
to contact the manufacturer of the original thermostat.

1.  Remove the mounting plate by pulling it straight off the back of 
the Thermostat. 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 mounting plate Figure 7., then install 
the other screw. Tighten both screws until secure. Figure 8.
Figure 11.
4.  Check the charts on the back of this sheet and identify your 
system type. They are divided by Conventional and Heat Pump 
installations.
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 
the  RH and RC terminals on the conventional side. Figure 9.
6.   If one of the terminals you need has a tab in front of it, use 
your nger to break the tab away. Figure 9.
Note:  Only  break  tabs  you  know  you  will  be  using.  Double 
check your wiring conguration and make sure you are familiar 
with the terminals you will be using.
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.
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 mounting plate, turn it 
over and nd 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 
or a heat pump. “Gas/Oil” will be used if you have gas or oil 
based conventional system. Figure 10.
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.
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 owner’s manual to continue setup, 
scheduling, and daily use.

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  thermostat’s  wiring  conguration 
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.
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.
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  hot  water 
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.
