thermostat buttons (page 1) and

display beginning on page 2.

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

CONFIGURATIONsection(page4,step

2).

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.

Configuration

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

FAN ON for the time period selected.

(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
