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 #7, page 12).
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 #7, page 12),
plus the 2nd stage deadband. This 2nd stage deadband is fixed at
two degrees and is not adjustable.

ELECTRIC HEAT - Selecting Electric Heat (step #6, page 12), 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
Cool setpoint display will read ‘EH’ (emergency heat).

by pressing the FAN and UP buttons. During Emergency Heat, only OFF

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 #8, on page 12. 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.
SINGLE SETPOINT BEHAVIOR - When configured as a Single Setpoint
thermostat, page 11, step 3, the large number is the setpoint. In Auto
mode the deadband is above and below the setpoint. To avoid short
cycling in single setpoint it is recommended that the deadband be set
for at least 2 degrees, page 12, step 7.

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

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
