DEADBAND OPERATION - Controls up to two Heat and two Cool stages
(please see the diagram on the next page).
The 1st Stage of heat or cool is turned on when:
(A) The temperature spread from the setpoint is equal to or greater
than: the setpoint plus the 1st stage deadband (step #6, page 13).
This 1st stage deadband is adjustable from 1-6 degrees and the
default is two degrees.
The 2nd Stage of heat or cool is turned on when:
(A) The 1st Stage has been on for a minimum of two minutes.
And
(B) The temperature spread from the setpoint is equal to or greater
than: the setpoint plus the 1st stage deadband (step #6, page 13),
plus the 2nd stage deadband. This 2nd stage deadband is fixed at
two degrees and is not adjustable.

ELECTRIC HEAT - Selecting Electric Heat (step #5, page 13), will cause the
thermostat to turn on the fan immediately any time there is a heat
demand. Since most gas furnaces control the fan, this feature should be
off unless it is necessary for the thermostat to energize the fan with first
stage heat.
EMERGENCY HEAT - Only available if you have a Heat Pump
installed. To initiate the Emergency Heat feature, press the FAN
button. While holding the FAN button press the UP button. The

HEAT/COOL DIFFERENTIAL - The Heat and Cool setpoints will not be
allowed to come any closer to each other than the value set in Advanced
Setup step #7, on page 13. This minimum difference is enforced during
Auto changeover and Program On operation.
Note: To increase the spread between the heating and cooling setpoints,
press the MODE button until only the heat setpoint is displayed; adjust to
the desired setpoint. Press the MODE button until only the cool setpoint
is displayed; adjust to the desired setpoint. Press the MODE button again
to enter the Auto-changeover mode where both the heat and cool
setpoints are displayed.
MEMORY BACKUP - In the event of a power loss, the thermostat will retain
the stored program settings without external power or batteries.
PROGRAMMABLE FAN - This timer will start the fan at the top of each
hour and the fan will run for the number of minutes selected in step #9 on
page 14. Steps 10 & 11 restrict the hours during which the programmable
fan may operate; step #10 is the start time and step #11 is the stop time.
Selecting the same start and stop times will cause the fan to operate 24
hours a day.

LOCKED icon will disappear from the display, then release the buttons.
OUTDOOR SENSORS (Optional Accessory) - One wired or wireless
Outdoor sensor can be installed to read the outdoor temperature. To
view this sensor, press and hold the MODE button for two seconds.
Press any button to exit the outdoor temperature display.
The Outdoor Sensor measures outdoor air temperature and sends this
information to the thermostat; it measures temperature with a range of
-40 to 127 F.
The Outdoor Sensor should be connected to the
thermostat using solid conductor CAT 5, CAT 5e,
or CAT 6 type network communication cable. This
is an unshielded cable with four twisted pairs of
24 gauge solid wire; DO NOT use stranded cable.
The cable length should not exceed 250 feet. If
less than 75 feet of cable is required to connect
the thermostat to the Outdoor Sensor, a three
conductor thermostat cable (18-24 gauge) may
be used; this cable is NOT suitable for any length
greater than 75 feet.
IMPORTANT: Do no use shielded wire. Do not run
run sensor wiring in the same conduit as the
24VAC thermostat wiring. Electrical interference
May cause the sensor to give incorrect temperature readings.
See the Outdoor Sensor instructions for further details.

Warranty
One-Year Warranty - This Product is warranted to be free from defects in material and
workmanship. If it appears within one year 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.
