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 applications 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 ° F and the thermostat is programmed for 70 ° F at 7 AM, 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

6

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 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 step 3).

(page 4,

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

7 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 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.

Configuration

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

RUN

PROGRAM. This dehumidification 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. To return the fan to normal operation before the end of the time period, press the FAN 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 operation.

Heat Fast.

to provide silent key

(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 HEAT 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.

8

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 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

9 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:

Configuration

MOR

DAY

EVE

NHT

L

AVG

HI

SENSOR

A

HI

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 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 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.

This will allow you to modify both the HEAT and COOL setpoints to accommodate a HOLD condition while in Automatic

Changeover mode. Note: For proper

Automatic Changeover mode the heating setpoint must be at least 1°F lower than the cooling setpoint in each program period. If the heating setpoint is equal to or higher than the cooling setpoint this causes is conflict. The thermostat will indicate a conflict by flashing the setpoint and will resolve the conflict by choosing a heating setpoint that is an average of the two program setpoints. The cooling setpoint will be two degrees higher than the heating setpoint.

Adjustable Temperature Display

The room temperature display can be adjusted to read higher or lower by following the configuration 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

19

Features thermostat displays a room temperature of 70° but you want it to display

73°, you can adjust it. To adjust, refer to the USER CONFIGURATION section (page 4, step 1).

Programmable Fan Control

This feature allows you to have your fan operate continuously through one or more programmed time periods.

This is useful if you want constant air circulation in your location during a specific time period. If you do not use this feature, the fan will cycle normally with the heating and cooling system.

Programmable Vacation Time/

Temperature Operation.

The VACATION mode allows you to program the thermostat to hold a constant temperature for 1 to 29 days.

At the end of the day and time you select, the thermostat will return to

normal program operation. To program the number of days, press the or

cancels this feature and begins running your normal program.

Keypad Lockout.

This security feature allows you to lock out the keypad to prevent unauthorized tampering with the program. Two levels of security are available, Total

Keypad Lockout or Partial Keypad

Lockout. Total Keypad Lockout renders all buttons inoperative. Partial

Keypad Lockout allows only the or to operate for temporary temperature overrides. It also limits the temperature to the maximum heating and minimum cooling temperatures used in your program. This is

20 especially useful in buildings where unscheduled events are common.

Anyone can change the temperature, but only between the temperatures you set and only for four hours or the number of hours you specify if you set up your Hold Till timing (see

Temporary Program Override, page

18). To select or deselect this feature, refer to the USER CONFIGURATION section (page 11, steps 1 and 2).

Thermostat Startup Up

After Power Loss.

The user program and installation and configuration settings are stored in permanent memory indefinitely. After a total power loss of 24V to the thermostat for more than 4 hours the clock and day settings will be lost.

When power is restored your thermostat will maintain a heating temperature of 62 ° F and a cooling temperature

of 85 ° F. If this happens, set the clock and day of the week (using steps 1 through 6 from “Entering Your

Program”, page 12 & 13), then select

HEAT, COOL or AUTO using the

SYSTEM

button, and press PRO-

GRAM

RUN

to resume operation with your previously set program.

Compressor

Short Cycle Protection.

Your thermostat can be configured to protect your system against premature compressor failure by “locking out” the compressor. This ensures that the compressor will stay off for at least five minutes on each cycle. When the thermostat is in compressor lock-out, the word COOL will flash. During this period, the compressor will not be energized. See the installation instructions.

Service Button Menu

The Service button allows setting of maintenance reminders for three optional equipment accessories typically used with forced air heating/ cooling systems. The three accessories humidifier, air filter, and UV light are designed to enhance indoor air quality.

A humidifier will add humidity when conditions would normally make the indoor air uncomfortably dry. Air filters are designed to clean the air through a forced air system. These accessories require routine maintenance to provide optimum performance. The service button maintenance reminders are designed so that they can be customized to the requirements of each accessory. If your system is a forced air system you may have none or all three accessories. The fourth maintenance reminder is for routine servicing of your system by a

21

System and

Thermostat Diagnostics.

The display will indicate CHECK

SYSTEM if the room temperature does not rise within two hours of the

call for heat. After two hours the thermostat will quit calling for heat for one minute (this allows some furnaces to reset) and call for heat again. If the temperature still does not rise, it will continue to call for heat. This normally indicates the heating system is not working correctly. You may wish to consult your furnace manufacturer or service person. The display will indicate CHECK STAT if one of the following occurs.

• One of the buttons is stuck down or in. Check buttons, make sure nothing is pushing them in.

• The thermostat sensor is not functioning. If using a remote sensor, check connections, wiring and power.

• The humidity sensor is not functioning. After checking the above, press

PROGRAM

RUN to reset the display. If this does not clear the display, disconnect power for five minutes. If these checks fail to solve the problem, the thermostat should be replaced.

Adjustable Humidity Display.

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 (up to 20% RH). The sensed humidity is calibrated at the factory. If you want to adjust it, refer to the CONFIGURATION section

(page 4, step 3).

Programmable Automatic

Humidity Reduction.

This feature automatically lowers humidity 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

25

Features 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.

OFF

Factory default — no humidity reduction.

LO

Well insulated homes requiring little humidity reduction.

HI

Poorly insulated homes or homes with a lot of condensation on windows/walls.

If your window insulation is poor, you need high humidity reduction. If your window insulation is good, you need low humidity reduction (factory setting). Selection of OFF will cancel this feature. To adjust this feature, refer to the CONFIGURATION section

(page 4, step 4).

FAQs

3. My furnace (air conditioning) cycles too fast

(slow). Is there an adjustment?

1F95-391

The 1F95-391 has a feature called Adjustable Heating and Cooling Cycle times (also called

Anticipation) that allows you to increase or decrease the cycle times in heating and cooling.

This is useful if you think your cycle times are too long or too short. The higher the number you select, the longer the cycle. The lower the number you select, the shorter the cycle. The

1F95-391 is adjusted in the Installer Table (see your installation instructions). The range of adjustment for HEATING is from 1 to 40. The factory Preset is 05, the range of adjustment for COOLING is from 9 to 40. The factory Preset is 24. The cooling will not go below 9 because compressors require a longer cycle. See page 6 of your Installation Instructions.

4. Why does the blower fan keep running after the system has shut off?

Normally the blower will turn off within a few minutes after the call for heat or cool. The blower running after the system shuts off may indicate (1) the thermostat is set to FAN ON,

(2) the fan has been programmed to run at that time period or (3) something has damaged the thermostat or equipment. If the thermostat display indicates FAN ON, press the fan button once to set it to FAN AUTO, meaning the fan will cycle only with the equipment. If the display indicates PRG FAN (Program Fan), sometime during programming, the

FAN button was pushed. To remove PRG FAN (Program Fan), check all of the programmed times and temperatures. When you encounter PRG FAN, press the

FAN

button to remove it from that time period in the program. As a final test, set the thermostat to OFF.

Verify that FAN ON or FAN AUTO is not displayed. If the fan continues to run, you may want to contact your heating and cooling service person for assistance.

Contact a Local Heating & Cooling service person or visit our website at

www.white-rodgers.com to consult our “Where to Buy” Service/Dealer locator.

11. What does CHCK PAD on the display mean and how do I reset it?

This feature displays the words CHCK PAD (check humidifier) after a set time of humidifier operation. This is a reminder to maintain or clean your humidifier. When CHCK PAD is displayed, you can clear it by pressing the SERVICE button.

12.When I push the

Humidity button, the display shows HUMD MX.

What does this mean?

HUMD MX indicates the humidifier has not reached the current humidity setting in the last

10 heating cycles. If the condition persists, a service person may recommend additional humidifier capacity.

13.Why does the system run with the setpoint and room temperature the same?

In cooling, as the room temperature falls you will eventually reach the setpoint temperature.

The system will continue to run until it reaches the low side of the temperature setting. As an example: If set to 78 degrees with the room temperature falling the thermostat will continue to call for cool as the temperature decreases in the following manner. 78.9, 78.8,

78.7, 78.6, 78.5, 78.4, 78.3, 78.2, at approximately 78.2 the thermostat will quit calling for cool. This is why it is not unusual for the room temperature and set temperature to read the same but the system continues to run. The amount of time it takes for the system to shut off

(cont.)

13.Why does the system run with the setpoint and room temperature the same?

is dependent on system sizing, thermostat location, etc. Note: The thermostat display only displays whole numbers. Internally the thermostat calculates decimals.

In heating as the room temperature increases the system will continue to run until the thermostat reaches the high side of the temperature setpoint.

14. How do I reset my thermostat?

There are 3 possibilities to consider, excluding tampering.

1. Loss of power from the system, 24VAC should be constant to maintain a display.

2. Static electricity or a voltage spike from the heating equipment might be resetting the thermostat. Static electricity can be eliminated by touching something before touching the thermostat to dissipate the static charge. A voltage spike from the equipment can be eliminated using an isolation relay as described in the link below.

http:www.white-rodgers.com/pdfs/instruction_sheets/0037_5426_A.pdf

You can also check the wire routing to verify the thermostat or remote wires are not running parallel to high voltage lines with high inductive loads which could (in extreme cases) create a voltage spike at the thermostat.

3. Thermostat not functioning properly. A simple test would be to bench test one of the units for a couple of days to see if it resets or move it to another system where a reset has never occurred.

15. How do I temporarily

Override the program and

Hold Til Timing?

16. What is the thermostat Click Test?

1F95-391

Any time your program is running and you would like to override it for a specific amount of time, press or until the temperature you want is displayed. The display will indicate HOLD, and the number of hours remaining in the hold period will be indicated with the word HRS. To adjust the length of time for the override, press TIME FWD or

TIME BACK. The time you select will become the new number of hours for the Hold Til timing. Once your time is selected, let the thermostat revert back to normal operation on its own to accept the change.

Many furnaces have safety devices that shut the system down when a lock-out condition occurs in the furnace. If the thermostat is turned off or the call for heat is cancelled (by lowering and then raising the set temperature) the furnace may start operating again. A diagnostic to see if the thermostat is operating when the room temperature is below the thermostat setting (in heat) is to lower the setting below the room temp. Within about 3 seconds the thermostat should make a soft click sound. This sound is the thermostat turning off the call for heat and usually indicates the thermostat is operating properly. If the thermostat does not click you would be suspicious of the thermostat and try resetting it by following it’s reset operation. If the thermostat does not click after being reset contact your heating and cooling service person or place of purchase for a replacement. If the thermostat clicks and the heat works intermittently contact the furnace manufacturer or local service person. They will want to observe the condition when it is not working.

16. What is the thermostat

Click Test?

1F95-391

You can raise and lower the temperature a few degrees above and below the room temperature and each time expect to hear the thermostat click on and off within a few seconds. If it clicks, it is operating properly.

17. What do AUX,

EMER, and MALF indicators mean on a heat pump thermostat?

Aux. = Auxiliary Heat or the second stage of heat in the Heat mode. This is energized when the Heat Pump is not keeping up with the thermostat setting. It is normal operation with most pumps for the thermostat to call for auxiliary heat.

Emer. = Emergency Heat. When switched to Emergency the thermostat bypasses the pump and uses the back-up heat. This is useful if the pump is not operating correctly or if the temperature outside is so cold that the pump is not economical to run.

Malf. = Malfunction. Malfunction indicates the heat pump system is sending a signal to the

Malfunction Light on the thermostat terminal marked “L”. It does not indicate a malfunction in the thermostat. The manufacturer of the Heat Pump system can determine the likely cause of malfunction indication on the thermostat.

In many heat pump systems Emergency and Auxiliary heat are the same source. If you switch the thermostat to Emergency it will bypass the heat pump and bring on the back-up heat. If you leave the thermostat in the Heat mode it will call for Auxiliary when the pump is not keeping up with your setpoint temperature. Emergency is energized on a call for heat in the Emergency heat mode.
