Carrier Programmable Dual Fuel Thermostats Installation, Start-Up, And Operating Instructions Manual page 5

press of SET TIME/TEMP button switches between the available
option (small display) and the available selections within each
option (large display).
CONFIGURATION OPTIONS—SELECTION:
Option 1—Anticipator Adjustment
This adjustment controls the sensitivity and cycle rate of the
thermostat. Higher numbers decrease the sensitivity and slow the
cycle rate. Lower numbers increase the sensitivity and cycle rate.
However, a limiting feature will not allow more than 4 cycles per
hour, regardless of setting. Anticipator values can range from 1 to
9. Factory default is 3. This default setting will provide optimum
performance in nearly all installations. Try it first. Do not change
setting unless there is evidence of need to do so.
Unlike conventional anticipators, this setting is not to be deter-
mined by current draw. There is not need to measure, know, or
compensate for current. There is also no droop with this thermo-
stat. Regardless of setting and the number of stages, both heating
and cooling will control to their respective set points.
TO ADJUST:
1. Enter configuration mode (if not already there). See above.
The upper small (COOL set point) display will be flashing 01.
If not, use up and down buttons to move it to 01.
2. Press SET TIME/TEMP button once to flash the current
selection of 1 through 9 on the large display. Factory default
is 3.
3. Use up and down buttons to move between the available
choices.
4. Press SET TIME/TEMP button again to flash the upper small
disply for selection of another option, or press END to exit the
configuration mode.
Option 2—Clean Filter Timer
Select hours of blower operation (heating, cooling, or fan) before
CLEAN FILTER icon is displayed. With OFF selected, icon will
never come on, disabling this feature. Time selection can be from
400 to 3600 hrs by selecting numbers 1 through 9. (Time is 400X
number selected.) Factory default is 2 (800 hrs). Recommended
selections are: disposable filter—400 to 800 hrs, media
filter—1200 to 1600 hrs, or electronic air cleaner—1600 to 2400
hrs of blower operation.
TO SELECT OR ADJUST:
1. Enter configuration mode if not already there. See above. Use
up and down buttons to make small (now flashing) display
indicate 02.
2. Press SET TIME/TEMP button once to flash current selection
of OF, or 1 through 9 on large display. Factory default is 2.
3. Use up and down buttons to move between the available
choices.
4. Press SET TIME/TEMP button again to flash upper small
display for selection of another option, or press END to exit
configuration mode.
Option 3—Fahrenheit or Celsius Operation
Select between Fahrenheit and Celsius operation. Factory default
is Fahrenheit.
TO SELECT:
1. Enter configuration mode if not already there. See above. Use
up and down buttons to make small (now flashing) display
indicate 03.
2. Press SET TIME/TEMP button once to flash current selection
of F or C. Factory default is F.
3. Use up and down buttons to move between C and F on large
display.
4. Press SET TIME/TEMP button again to flash upper small
display for selection of another option, or press END to exit
the configuration mode.
Option 8—Auxiliary Heat Lockout Setting
This option allows selection of an outdoor temperature of 5°
through 55°F in 5° steps (or equivalent values in C), or OF (off).
Furnace is prevented from operating for outdoor temperatures
above the selected temperature. If OF (off) is selected, furnace
operation is allowed at all outdoor temperatures. If selected,
emergency heat (EHEAT) overrides this feature. Factory default is
OF. This setting can only be equal to or above the setting choice
made for Option 11. Moving this setting lower may "push" Option
11 setting downward.
TO SELECT:
1. Enter configuration mode if not already there. See above. Use
up and down buttons to make small (now flashing) display
indicate 08.
2. Press SET TIME/TEMP button once to flash large display.
3. Use up and down buttons to move between 5, 10, 15, 20, 25,
30, 35, 40, 45, 50, 55, or OF on large display. Factory default
is OF. Remember, this may change setting for Option 11.
4. Press SET TIME/TEMP button again to flash upper small
display for selection of another option, or press END to exit
the configuration mode.
Option 11—Balance Point Setting
This option allows selection of an outdoor temperature of 5°
through 55°F in 5° steps (or equivalent values in C), or OF (off).
Heat pump is prevented from operating for outdoor temperatures
below selected temperature. If OF (off) is selected, heat pump
operation is allowed at all outdoor temperatures. Factory default is
OF. This setting can only be equal to or below the setting choice
made for Option 8. Moving this setting higher may "push" Option
8 setting upward.
TO SELECT:
1. Enter configuration mode if not already there. See above. Use
up and down buttons to make small (now flashing) display
indicate 11.
2. Press SET TIME/TEMP button once to flash large display.
3. Use up and down buttons to move between 5, 10, 15, 20, 25,
30, 35, 40, 45, 50, 55, or OF on large display. Factory default
is OF. Remember, this may change setting for Option 8.
4. Press SET TIME/TEMP button again to flash upper small
display for selection of another option, or press END to exit
configuration mode.
Option 13—Room Temperature Offset Adjustment
This option allows calibration (or deliberate miscalibration) of the
room temperature sensor. There are various reasons why home-
owners may want to have the displayed temperature adjusted to a
higher or lower value. The selected number is the number of
degrees, plus or minus, which will be added to the actual
temperature. The numbers can range between -5 and +5. Factory
default is 0. This adjusted value will be used as the actual
temperature for both the display and the control action. For
example, if 2 is selected. 72° actual will read 74°. If set point is 72°
then the room will control to an actual temperature of 70° which
will be displayed and acted upon as if it were 72°. The effect is that
a positive number selection will make the room temperature lower
and vice versa. The thermostat is calibrated within an accuracy of
plus or minus 1° when shipped from the factory, so this adjustment
will provide the best accuracy when set to 0.
