to before cooling is turned on (without regard to deadband).
Deadband: The number of degrees the thermostat will wait, once a
setpoint has been reached, before energizing heating or cooling.
Differential: The forced temperature difference between the heat set-
point and the cool setpoint.
Heat Setpoint: The coolest temperature that the space should drop
to before heating is turned on (without regard to deadband).
Icon: The word or symbol that appears on the thermostat display.

Installation Instructions
Remove & Replace the Old Thermostat
To install the thermostat properly, please follow these step by
step instructions. If you are unsure about any of these steps,
call a qualified technician for assistance.
Assemble tools: Flat blade screwdriver, wire cutters and wire
strippers.
Make sure your Heater/Air Conditioner is working properly
before beginning installation of the thermostat.
Carefully unpack the thermostat. Save the screws, any brackets, and instructions.
Turn off the power to the Heating/Air Conditioning system at
the main fuse panel. Most residential systems have a separate
breaker for disconnecting power to the furnace.
Remove the cover of the old thermostat. If it does not come off
easily, check for screws.
Loosen the screws holding the thermostat base or subbase to the
wall and lift away.
Disconnect the wires from the old thermostat. Tape the ends
of the wires as you disconnect them, and mark them with the
letter of the terminal for easy reconnection to the new thermostat.
Keep the old thermostat for reference purposes, until your new
thermostat is functioning properly.

This jumper configures the thermostat to control a conventional
gas/electric system or a heat pump. If your system is anything
other than a heat pump, leave this jumper set for GAS/ELEC.*
*For some commercial heat pumps, this jumper will need to
be set for GAS/ELEC. Consult the commercial heat pump literature.
When J1 is configured to control a heat pump, this jumper (J2)
must be set to control the appropriate reversing valve. If RV=O
is chosen, the W1/O/B terminal will energize in cooling. If RV=B
is chosen, the W1/O/B terminal will energize in heating.
When J1 is set for GAS/ELEC:

Warranty
Five-Year Warranty - This Product is warranted to be free from defects in material and
workmanship. If it appears within five years from the date of original installation, whether or not
actual use begins on that date, that the product does not meet this warranty, a new or
remanufactured part, at the manufacturer’s sole option to replace any defective part, will be
provided without charge for the part itself provided the defective part is returned to the distributor
through a qualified servicing dealer.
THIS WARRANTY DOES NOT INCLUDE LABOR OR OTHER COSTS incurred for diagnosing, repairing,
removing, installing, shipping, servicing or handling of either defective parts or replacement
parts. Such costs may be covered by a separate warranty provided by the installer.
THIS WARRANTY APPLIES ONLY TO PRODUCTS IN THEIR ORIGINAL INSTALLATION LOCATION AND
BECOMES VOID UPON REINSTALLATION.
LIMITATIONS OF WARRANTIES – ALL IMPLIED WARRANTIES (INCLUDING IMPLIED WARRANTIES OF
FITNESS FOR A PARTICULAR PURPOSE AND MERCHANTABILITY) ARE HEREBY LIMITED IN DURATION TO
THE PERIOD FOR WHICH THE LIMITED WARRANTY IS GIVEN. SOME STATES DO NOT ALLOW LIMITATIONS
ON HOW LONG AN IMPLIED WARRANTY LASTS, SO THE ABOVE MAY NOT APPLY TO YOU. THE
EXPRESSED WARRANTIES MADE IN THIS WARRANTY ARE EXCLUSIVE AND MAY NOT BE ALTERED,
ENLARGED, OR CHANGED BY ANY DISTRIBUTOR, DEALER, OR OTHER PERSON WHATSOEVER.
ALL WORK UNDER THE TERMS OF THIS WARRANTY SHALL BE PERFORMED DURING NORMAL WORKING
HOURS. ALL REPLACEMENT PARTS, WHETHER NEW OR REMANUFACTURED, ASSUME AS THEIR
WARRANTY PERIOD ONLY THE REMAINING TIME PERIOD OF THIS WARRANTY.
THE MANUFACTURER WILL NOT BE RESPONSIBLE FOR:
1. Normal maintenance as outlined in the installation and servicing instructions or owner’s
manual, including filter cleaning and/or replacement and lubrication.
2. Damage or repairs required as a consequence of faulty installation, misapplication, abuse,
improper servicing, unauthorized alteration or improper operation.
3. Failure to start due to voltage conditions, blown fuses, open circuit breakers or other
damages due to the inadequacy or interruption of electrical service.
4. Damage as a result of floods, winds, fires, lightning, accidents, corrosive environments or
other conditions beyond the control of the Manufacturer.
5. Parts not supplied or designated by the Manufacturer, or damages resulting from their use.
6. Manufacturer products installed outside the continental U.S.A., Alaska, Hawaii, and
Canada.
7. Electricity or fuel costs or increases in electricity or fuel costs for any reason whatsoever
including additional or unusual use of supplemental electric heat.
8. ANY SPECIAL INDIRECT OR CONSEQUENTIAL PROPERTY OR COMMERCIAL
DAMAGE OF ANY NATURE WHATSOEVER. Some states do not allow the exclusion of
incidental or consequential damages, so the above may not apply to you.
This warranty gives you specific legal rights and you may also have other rights which may vary
from state to state.
