CHOOSING A LOCATION FOR A NEW THERMOSTA
Near or in a frequently occupied room, preferably on an inside partitioning wall.
On a section of the wall without pipes or duct-work.
Near a window, on an outside wall, or next to a door leading outside.
This thermostat should NOT be mounted:
Exposed to direct light or heat from the sun, lamp, fireplace, or other heat radiating
objects which may cause false readings.
Near or in a direct airflow from supply registers and return-air grilles.
Near concealed pipes and chimneys.
In areas of poor air circulation, such as behind a door or in an alcove.

COMPATIBILITY
Generally, equipment with low voltage control is compatible with the thermostat. For details
on compatibility of your particular equipment, please call technical support at 1-888-468-6876.
* NOT COMPATIBLE WITH ANY 120/240 V CIRCUIT.
INSTALLATION
The following tools may be required for installation:
( ) screwdriver
Masking tape (To wrap the exposed wires temporarily and labeling the discon
Wire stripper/cutter (If necessary, to strip wires)
Power drill with a 3/16” bit (If necessary, to drill holes on the wall)
Level (If necessary, to level the thermostat)
INSTALLATION
REPLACING OLD THERMOSTAT
TURN OFF POWER to system at the furnace, or at the fuse/circuit breaker panel.
Carefully unpack your new thermostat and mounting plate; save package of screws,
instructions and receipt.
Remove cover from old thermostat. If it does not snap off when pulled firmly from the
bottom, check for a screw used to secure the cover.
Loosen screws holding thermostat to the wall and lift away the thermostat.
Disconnect wires from old thermostat or sub-base. As you disconnect each wire, use
masking tape to label it with the old terminal designation. If there are only two wires,
they don't need to be labeled.
If there is an extra wire that is not connected to your old thermostat, then you won't
need to connect it to the new thermostat.
After choosing a location for the new thermostat, you may arrange to have a
heating contractor install the control wiring for you.
Do not operate the cooling system when outside temperature is below 10
(50 ) to avoid damaging the compressor.

*
Test the system to make sure that your heating and cooling systems are working
properly before installation. If either does not work, contact a local heating/air
conditioning service person to fix the problem before installation.
Take care not to let the wires fall back into the wall or let the ends of the wires touch
one another.
The wires are usually designated 'W', 'Y', 'G', 'R’
INSTALLATION
MOUNTING THE THERMOSTAT BACK COVER
The back cover should be mounted with the large hole on the top.
Thread the existing wiring through the large hole from the back and set the back
cover flat on the wall.
Select two appropriate mounting holes and mark the locations with a pencil. If
necessary, use a level to make sure the thermostat is leveled.
Remove the back cover from the wall and drill two 3/16” holes in the marked screw
positions.
Insert the wall anchors into the holes completely. If necessary, use a hammer to
tap-in lightly.
Mount the back cover, with the two screws, to
on the top-half of the back cover.
Carefully separate the back cover from the thermostat by disengaging the 4 latches
found at the corners on the back of the thermostat. Pull firmly but DO NOT try to pry
open with a screwdriver.
INSTALLATION
CONNECTING THE WIRES TO THE TERMINALS
Depending on your heating/cooling equipment, you may
need to connect 2 to 5 wires to the thermostat.
If your old thermostat has a ‘C’ wire, please wrap it with
electrician’s tape as it is not used with this thermostat.
If you have both an ‘R’ and ‘Rc’ wire, you may connect
them together to the ‘R’ terminal of the thermostat.
If you are unsure of the connections, or for new
installation, you may refer to the wiring diagrams below.
Connect the previously labeled wires to the corresponding terminals, matching the
designations. Use a screwdriver to securely fasten the wires onto the terminals. Make sure
the wires do not short-circuit with other terminals.

INSTALLATION
SETTING THE FAN OPERATION JUMPER
Depending on your home’s heating system, you may need to change the jumper setting for
the fan operation. The jumper is located above the battery compartment.
HG - Use this setting for gas or oil-fired furnaces. This setting allows the fan
operation to be controlled by the heating system; not the thermostat. This is the
correct setting for most systems.
HE - Use this setting for electric heating systems. With this setting, the thermostat
will turn on the fan immediately with the heating system.
The jumper is pre-installed in the ‘HG ’ position as a factory default. So there is no need to
change the jumper if this is the correct setting.
To change the jumper setting, pull out the small black rectangular block and align it to the
new position and push in fully.
INSTALLATION
BATTERY INSTALLATION
2 “AA
batteries are low. It is recommended that the batteries be replaced at least once a year
Remove the back cover from the thermostat.
Insert the 2 “AA
polarity as marked.
Immediately following the battery installation, the thermostat will enter the °C/°F
selection mode. The current temperature will appear with the temperature scale
(in °C) flashing.
SELECTING THE DISPLAY IN C or F°°
Re-attach the back cover.
NOTE: To select the temperature display format in °C or °F
following the battery installation.
Use the UP or DOWN button to select the desired temperature scale (in °C or °F).
Otherwise, if no buttons are pressed within 12 seconds, °C will automatically be
selected, and the thermostat will go to its operation mode.
NOTE: Selecting the °C or °F display is a one-time process. Therefore, if you wish to change
it at a later time, you will need to reset the thermostat by pressing the RESET key
above the battery compartment and select °C or °F using the UP or DOWN button.
Attach the thermostat body to the back cover (that is already installed on the wall) by
carefully aligning the two pieces and firmly snapping the 4 latches at the back of the
thermostat.
ATTACHING THE THERMOSTAT TO THE BACK COVER
TURN OFF POWER to system at the furnace, or at the fuse/circuit breaker before wiring.

1) Check and ensure that the thermostat is set to the HEAT mode.
2) Check and ensure that the set temperature is higher than the current (room) temperature.
3) You may have to wait up to 2 minutes before the heat will turn on. The thermostat has a
built-in time delay to prevent undesirable on/off sequences.
4) After a 2-minute wait, the heating should now be on. Whenever the heating system is
running, the “ON ” icon will be flashing.
1) Check if the furnace switch and/or pilot flame is turned on, as it may have been turned off.
2) Allow several minutes for the heating system to heat up and the fan to activate. Most
heaters will heat up the system for a short while before warm air can be ventilated by the
fan. Also check that the HE/HG setting is set correctly. (Refer to page 7).
3) If the heat still does not come on, check the wiring installation again. (Refer to page 6).
1) Check and ensure that the thermostat is set to the COOL mode.
2) Check and ensure that the set temperature is lower than the current (room) temperature.
3) You may have to wait up to 5 minutes before the air conditioning will turn on. The
thermostat has a built-in time delay to protect the air conditioner compressor from
undesirable on/off sequences.
4) After a 5-minute wait, the air conditioning should now be on. Whenever the cooling
system is running, the “ON ” icon will be flashing.
1) Check if the air conditioning system’s main switch is turned on, as it may have been
turned off.
2) Wait several minutes for the air conditioning system to activate. If the air conditioning still
does not come on, check the wiring installation again. (Refer to page 6).
RESET
If the thermostat shows an abnormal display or if you
wish to change the temperature scale (°C or °F), use a
pointed object to press the RESET key.
