CONFIGURATION MENU
FEATURES
AdjustableTemperature Display.
(User menu, Item 1), The room
temperature display can be adjusted to
read higher or lower by following the
User menu and adjusting the tempera-
ture to a higher or lower value. The
thermostat is calibrated at the factory to
display a very accurate room tempera-
ture, but due to various conditions and/
or personal preference, you may wish to
adjust the thermostat display higher or
lower (up to 5°F). For example, if the
thermostat displays a room temperature
of 70°and you want it to display 73°the
display can be adjusted to read 73°. To
adjust,referto theCONFIGURATION
section (page 5, step 1).
Selectable Energy Management
Recovery (EMR).
(User menu, Step 2) EMR causes the
thermostat to start operating the system
early in order to make the building
temperature reach your program
setpoint at the time you specify. In
multistage heating, the thermostat will
start 8 minutes early for every 1°F
difference between the room tempera-
ture and the next programmed
temperature. In cooling and heat pump
applications, the thermostat uses 15
minutes per °F. For heating applica-
tions in large buildings where extra
time to reach the set temperature may
be desired, EMR Long may be selected.
When EMR ON L is selected in the
user menu (page 5, item 2) the
thermostat uses 15 minutes per °F.
EXAMPLE: If the temperature in the
room is 65°F and the thermostat is
programmed for 70°F at 7AM, the
thermostat will start approximately 40
minutes early. The difference between the
room temperature (65°F) and the setpoint
(70°F) is 5°and 5°X 8 minutes per °F =
40 minutes. The setpoint on the display
will actually change to display 70°about
40 minutes early. The maximum time the
thermostat can start early in heating is 75
minutes (or 3 hours,45 minutes if EMR
ONLisselected).Themaximumtime in
coolingandheatpumpapplications is 3
hours and 45 minutes. Cooling or heat

AdjustableHumidityDisplay(RH)
(User Menu step 3) The room
humidity display can be adjusted to
read higher or lower by following the
configuration menu and adjusting the
humidity to a higher or lower value.
The thermostat is calibrated at the
factory to display a very accurate
room humidity, but due to various
conditions and/or personal preference,
you may wish to adjust the thermostat
display higher or lower (up to +/-
20%). For example, if the thermostat
displays room humidity of 40% but
you want it to display 43% you can
adjust it. To adjust, refer to the
CONFIGURATION section (page 4,
step 3).
ProgrammableAutomatic
Humidity Reduction (DRY)
(User Menu step 4) This feature
automatically lowers humidity setting
when the outside temperature drops.
This is to prevent the interior windows/
walls from reaching the dew point
where water condenses on surfaces. To
achieve automatic humidity reduction,
the thermostat lowers the humidity
when furnace cycles are long.When the
furnace runs shorter cycles, it increases
humidity. For suggested settings see
table below.
ProgrammableDehumidification
OptimalComfort Mode(OPTM
CMFT)
(User Menu step 5)When turned on
this feature automatically reduces
indoor humidity during calls for
cooling if humidity is 2% above setting.
Humidity is set by pressing the
Humidity button when in the appropri-
ate mode, in this case Cooling, and
pressing the or buttons to
set desired humidity (range 40 to 95)
level followed by pressing Run
Program. This dehumidification feature
uses less energy by maintaining
temperature and dehumidifying only
when a call for Cooling is required.
Fahrenheit or Celsius
Temperature Display.
(User menu, Step 6) This thermostat is
factory set to display temperature in
Fahrenheit. If you prefer, you may
configure the thermostat to display
Celsius. See the CONFIGURATION
Section, page 4.

Single Period Fan Control.
(User menu, Step 7) This feature
allows you to have the fan run for a
predetermined period of time by
pressing the FAN key twice within 1.5
seconds. If a time is set in the User
menu (page 4, step 8) the display will
show FAN, # hrs and PRG FAN ON
forsix seconds.After six secondsthe
displaywill continue to indicatePRG

Cool Fast.
(User menu, Step 10) This feature,
when set to ON, will bring the second
stage of cooling on any time you
manually lower the temperature three
or more degrees below room tempera-
ture. If COOL FAST is set to OFF,
the thermostat will delay the second
stage from 0 to 30 minutes based on
how well the first stage is keeping up
with your setting.
Optional Remote Temperature
Sense.
(User menu, Step 11,12,13,14) Up to
three remote sensors (F145-1328) can
be attached to this thermostat to sense
indoor temperature at locations away
from the thermostat. Each sensor may
be located as far as 300 feet away from
the thermostat. This is an excellent
feature if the thermostat is in a poor
location for sensing temperature or if
you want to install the thermostat in a
separate room to prevent tampering.
After installing and connecting the
remote sensor(s) to the thermostat, the
installer can enable each remote indoor
temperature sensor (A, B, and/or C).
When operating with remote sensor(s),
the thermostat will calculate an
average of the sensed temperatures in
all enabled sensor locations (A, B, C
and/or L), then display the average
