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

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

9
temperature as the room temperature.
The temperature at each remote sensor
can be displayed by pressing the light
button twice within one second. With
the thermostat in program run or hold
mode. Temperatures at the outdoor and
indoor remote sensors will be
displayed with subsequent presses of
the light button in the following order
(if connected): outdoor sensor, sensor
L, A, B, C. You can also assign each
sensor different priorities during
different program periods. This allows
the system to maintain a comfortable
environment by giving higher priority
to occupied locations.At the same time,
giving lower priority to unoccupied
locations enhances efficient system
operation. EXAMPLE:Your home has
bedrooms on the upper level and a
guest bedroom on the main level, along
with the living room, kitchen, etc. The
thermostat (sensor L) is located in the
hall on the main level. Remote sensors
are located on the upper level (sensor
A) and the guest bedroom (sensor B).
The lower level would be occupied in
the DAYand EVE periods. The upper
level would be occupied in the NHT
and MOR periods. With no guest in the
guest bedroom, the sensors could be
programmed as follows:
In the MOR and NHT periods, the
sensor on the upper level (sensorA) has
more priority than the lower level
(sensor L), so the system will operate to
keep the temperature at the set point in
the upper level. In the DAY and EVE
periods, the lower level has the higher
priority, so the system will operate to
keep the temperature at the set point on
that level. The sensor in the guest
bedroom has the lower priority of the
sensors. If there is a guest, the sensor in
that room (sensor B) should be
changed to AVG or HI for periods
when that room will be used. To assign
priority to a sensor, press PROGRAM
VIEW
to advance the time period you
wish to modify, then press the
HUMIDITY button. On the display in
place of period of day (MOR, DAY,
EVE, NHT) the priority of the sensor
and the sensor identification will
appear. Press the HUMIDITY button

you wish to change is displayed, press
the DAYLIGHT SAVINGTIME key
to change the priority (AVG, HI orLO).
AVG is the default setting.A setting of
HI gives a sensor more importance and
a setting of LO gives less importance.
OutdoorTemperature Sense.
(User menu, Step 15) A remote sensor
(F145-1378) may be installed for
outdoor temperature measurement. The
sensor must be properly connected and
enabled using the User menu. The
display shows the outdoor temperature
from -40°to 140°F by pressing the
light button twice within one second
when the thermostat is in program run
or hold mode.
