CONFIGURATION MENU FEATURES

Adjustable Temperature 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 temperature to a higher or lower value. The thermostat is calibrated at the factory to display a very accurate room temperature, 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, refer to the CONFIGURATION section (page 4, 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 temperature 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 4, item 2) the

thermostat uses 15 minutes per °F.

EXAMPLE: If the temperature in the room is 65 programmed for 70

°F and the thermostat is

°F at 7 AM, the

thermostat will start approximately 40 minutes early. The difference between the room temperature (65

(70

°F) is 5° and 5° X 8 minutes per °F =

°F) and the setpoint

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 ON L is selected). The maximum time in cooling and heat pump applications is 3 hours and 45 minutes. Cooling or heat pump applications start earlier because it takes longer to reach the desired temperature. This feature also minimizes the use of the auxiliary stages if conditions are such that the compressor stages are adequate to reach the desired setpoint. To select or deselect this feature, refer to the CONFIGURATION section (page 4, step 2).

Adjustable Humidity Display (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

Configuration

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).

Programmable Automatic 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.

Programmable Dehumidification Optimal Comfort 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 appropriate mode, in this case Cooling, and pressing the 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.

or buttons to

Programmable Dehumidification Optimal Dehumidification Mode (OPTM DHUM)

(User Menu step 6)When turned on this feature automatically reduces indoor humidity if humidity is 2% above setting. Humidity is set by pressing the HUMIDITY button when in the appropriate mode, in this case Cooling, and pressing the

or buttons to set desired humidity level followed by pressing

PROGRAM. This dehumidifi-

RUN

cation feature may use more energy by making dehumidification a priority initiating a call for cooling if humidity is 2% above desired setting. This feature may also over-cool the condition space by up to 3 degrees to achieve the desired humidity level.

Fahrenheit or Celsius Temperature Display.

(User menu, Step 7) 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 5.

Single Period Fan Control.

(User menu, Step 8) 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 for six seconds. After six seconds the display will continue to indicate PRG FAN ON for the time period selected. After this time period, the fan will return to normal operation. T o return the

fan to normal operation before the end of the time period, press the F AN button.

Beeper on.

(User menu, Step 9) The thermostat has a beeper that will emit a tone when any key is pressed. In the user menu, the BEEP feature can be turned OFF using

or to provide silent key

operation.

Heat Fast.

(User menu, Step 10) This feature, when set to ON, will bring the second stage of heating on any time you manually raise the temperature three or more degrees above room temperature. If HEA T 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.

Cool Fast.

(User menu, Step 11) 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 temperature. 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 12,13,14,15) 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

Configuration

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 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 DAY and 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:

SENSOR

MOR DAY EVE NHT

AVG

HI HI

AVG

HI AVG AVG

B LO LO LO LO

In the MOR and NHT periods, the sensor on the upper level (sensor A) 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 AV G 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 HUMID- ITY button to step through the sensors

that are installed and enabled L (local), A, B or C. Only sensors that are

installed and enabled will be listed. When the sensor you wish to change is displayed, press the DAYLIGHT SAVING TIME key to change the

priority (AVG, HI or LO). AVG is the default setting. A setting of HI gives a

sensor more importance and a setting

of LO gives less importance.

Outdoor Temperature Sense.

(User menu, Step 16) 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.
