MOUNTING LOCATION:

On replacement installations, mount the new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new installations, please follow these general guidelines:

1. Mount the thermostat on an inside wall, about 5 ft. (1.5m) above the floor.

2. Do not locate the thermostat where air circulation is poor such as in a corner, alcove, or behind a door that is normally left open.

3. Do not locate the thermostat where unusual heating or cooling conditions may be present, such as: direct sunlight, above a lamp, television, or radiator, or on a wall next to an exterior door or window.

4. Do not locate in a damp environment, as this can lead to corrosion that may shorten thermostat life.

5. If painting or construction work is still ongoing, cover the thermostat completely or wait until this work is complete before installation.

WARNING:

All wiring must conform to the local codes and ordinances that are in your particular location.

REMOVE OLD THERMOSTAT:

1. Turn OFF the electricity to all heating and cooling components. Do not turn the electricity back on until all work is completed.

2. Remove the front portion of your old thermostat to expose the wiring connections.

3. Write down the letters printed near each wire terminal that is used, and also the color of each wire that is connected to it. Self-adhesive wire

OFF labels are also enclosed.

4. Carefully remove the wires one at a time, and bend them in a manner so that they do not fall back inside the wall. Do not allow bare wire ends to touch each other.

5. Loosen the mounting screws for the old thermostat and carefully remove it from the wall.

THERMOSTAT TOP VIEW

1. Strip wire insulation leaving only 3/8 in. (9.5mm) bare wire ends, and clean off any corrosion present.

2. Fill the wall opening with non-combustible insulation to prevent drafts from affecting the thermostat’s normal operation.

3. Route the wires through the opening in the new thermostat base plate, and hold the base against the wall. Try to line up the screw holes from the prior thermostat, and install the mounting screws.

4. If the previous holes cannot be used, hold the thermostat base against the wall so that it appears straight and level (position the base for best appearance) and mark for the new screw holes. Attach the base to the wall using the screws provided (use the supplied plastic anchors if needed when mounting to a soft material such as drywall).

WIRING INFORMATION:

CONNECTING THE WIRES:

When attaching the wires to the thermostat, please ensure that the bare wire ends are held ALL the way into the terminal block while the screw is being tightened.

WIRING BASE PLATE NOTICE:

This thermostat model is part of a family of similar models that have the same general visual appearance. Even though this base plate may look the same as base plates from other models, the wiring connections may have different terminal letters for different purposes. Please do not interchange the back plates and/or thermostat front halves of other similar looking models. Doing so may cause undesired heating and/or cooling operation to occur.

WIRING DIAGRAM NOTES:

(Important, please read all notes before connecting wires)

• If the information provided in the following wiring diagrams does not clearly represent or match your system, please refer to the “TECHNICAL

ASSISTANCE” section of this manual, and contact us before removing any of your existing thermostat wiring.

• All of the dashed wires shown in the wiring diagrams are either optional, or their usage depends upon your specific system type or brand. For example: Diagram #1 shows the fan wire as optional. If your system does not have a fan, than this terminal will not be used.

• Terminal letters shown in black represent typical wiring applications.

Depending upon the brand of your specific system or thermostat, your terminal letters may not match exactly. Terminal letters shown in gray represent other possible wiring designations that you might see on your existing thermostat terminals.

• The optional “C” terminal is used for powering the thermostat by the 24volt system, using the System Common wire. This can be used alone, or in addition to installing batteries as a backup. NOTE: connecting the

System Common wire to the thermostat is not necessary for heating and cooling to function properly.

• If your old thermostat has both a “Y” and “C” wire present, then “C” is most likely a System Common wire.

• For Heat Pump systems, you will use either the “O” terminal or the “B” terminal on this thermostat, but not both. If your old thermostat has both an “O” and a “B” wire present, then “B” is likely a System Common wire and may be connected to the “C” terminal. Connecting a System Common wire to this thermostat’s “B” terminal may damage the thermostat, and also your heating and cooling system.

• Some Heat Pump systems have a wire for AUX electric heat (usually W2), and also a separate wire for Emergency electric heat (usually E). This thermostat uses the W2 terminal for both AUX and Emergency Heat. Tape off your “E” wire, and confirm that all components function without it.

• If replacing an old thermostat that has a mechanical clock, there may be two wires labeled as “C” for the clock power. Tape off these wires and do not connect them to the “C” terminal of this thermostat.

HARDWARE SETUP OPTIONS:

On the thermostat’s circuit board, there is a row of DIP switches, labeled #1 through #8. The position of these switches will change how the thermostat operates, and also how information is conveyed to you on the LCD display screen. If you make any changes to these options, the changes are not recognized unless you either: change the position of the HEAT/OFF/COOL mode switch, or press the “HW RST” (Hardware Reset) button on the circuit board. The use of this button is further described in the “ADVANCED FEATURES” section of this manual.

These option switches are very small and should be moved carefully using objects such as: eyeglass screwdriver, fine-point pen, toothpick, or similar. The listing below describes the available choices for each option switch:

SWITCH #1 (SYSTEM): [OFF/RIGHT = FURN, default] This setting is used for the majority of all heating systems that are not heat pumps. Examples for this setting would be: natural gas furnace, hot water baseboard heat, and oil heat. [ON/LEFT = HP] Use this setting if you have a heat pump unit (which looks just like an outside air conditioning unit, but is used for both cooing and heating).

SWITCH #2 (TYPE): [OFF/RIGHT = PROG, default] The thermostat controls the room temperature by following temperature program periods that you set up based upon your daily routine. [ON/LEFT = MAN] The thermostat operates manually just like a mechanical or non-programmable model. This method of operation is very basic and only shows the room temperature and set temperature; there are no temperature programs, days of the week, or clock times.

SWITCH #3 (PERIODS): [OFF/RIGHT = 4, default] The thermostat uses four temperature program periods in both heating and cooling (MORN, DAY, EVE, and NITE). Each period has a separate start time and a set temperature.

[ON/LEFT = 2] The thermostat operates in the same manner as above, however there are only two temperature program periods for heating and cooling (DAY and NITE). This may be more convenient if you are typically home during the day, and only need the set temperature to be different while you are sleeping.

17

SWITCH #4 (SCALE): [OFF/RIGHT = F, default] All temperature values are displayed using the Fahrenheit scale. [ON/LEFT = C] This setting displays all temperature values using the Celsius scale.

SWITCH #5 (TIME): [OFF/RIGHT = 12 HR, default] This setting displays the clock times and temperature program period start time values on the screen using US standard AM and PM values. [ON/LEFT = 24 HR] This setting displays the clock and temperature program period start time values on the screen using the 24 HR military-time format (17:30 hours, 22:00 hours, without using AM/PM).

SWITCH #6 (DELAY): [OFF/RIGHT = 5 MIN, default] This sets the minimum length of time that Heat or Cool must remain either On or Off, before it will automatically switch to the alternate On or Off state. This internal delay prevents rapid cycling of your system and provides equipment protection particularly for cooling units. The 5-minute setting is fine for most applications. [ON/LEFT = 2 MIN] If you feel that your system may need to cycle more frequently than the thermostat is allowing, then you may use the

2-minute setting.

SWITCH #7 (RECOVERY): [OFF/RIGHT = DISABLE, default] The Early

Recovery feature affects how the thermostat transitions from an energy saving setback (DAY and NITE) program period, to a comfort (MORN and

EVE) program period temperature, when it is following the daily temperature programs. When this is disabled, the thermostat makes a set temperature change at the beginning of an upcoming period's start time. [ON/LEFT =

ENABLE] The Early Recovery feature will calculate the capability of your system and turn on the heating or cooling early so that the temperature in your home reaches the desired set point as close as possible to the start of the period. During the time that the thermostat is performing a recovery, the words “IN RECOVERY” will be shown, alternating at the top of the display with the current system mode.

SWITCH #8 (BATTERY MONITOR): [OFF/RIGHT = ON, default] This setting, regularly monitors the battery level, and shows “LOW BAT” on the screen if the batteries need to be replaced. Use this setting at all times when batteries are present in the thermostat. [ON/LEFT = OFF] This setting only applies if you are NOT physically using batteries in the thermostat, and are powering the thermostat entirely from the system (“C” wire terminal).

18

GAS / ELEC SLIDE SWITCH (FAN OPERATION):

This switch is a physical component by itself on the circuit board, and is much larger than the

DIP switches listed above. [DOWN = GAS, default] This setting lets the heating system control the blower fan automatically by itself.

Systems that would typically use the “GAS” setting would be: natural gas, propane, or oil

GAS

BATTERY furnaces. This setting has no effect upon Cool mode operation. [UP = ELEC/HP] This setting

ELEC runs the system’s blower fan when heat is called for, and is required for heating systems that do not control their own fan while the thermostat is in HEAT mode. Heat pump systems, and units with an electric heating element typically require this setting.

COMPLETE THE INSTALL:

Once the hardware options are set, install two new Energizer ® or DURACELL ®

"AA" size alkaline batteries. Ensure that the batteries are installed in the proper direction as per the markings shown in the battery tray. If the batteries were already installed before changing the hardware setup options, change the position of the HEAT/OFF/COOL System Mode switch to accept the new hardware option switch settings.

FRONT PANEL ITEMS:

These two items below are both located on the right side of the thermostat housing.

HEAT / OFF / COOL, SYSTEM MODE SWITCH: Set this switch to HEAT to control your heating system, and COOL to control your cooling system. The

OFF position will disable both the heating and cooling units.

AUTO / ON, FAN MODE SWITCH: When this switch is in AUTO, the blower fan

(if present in your system) will automatically cycle on and off by itself while heating or cooling is running. When in the ON position, the blower fan will run constantly with or without a demand for heating or cooling, even when the System Mode switch is in the OFF position.

19

NOTE: The Fan Mode switch only works if your system provides a wire for the thermostat’s “G” wire terminal, to control a blower fan. The Fan Mode switch has no effect in systems that do not have a blower fan (such as a hot water radiator system).

There are on-screen indicators to show you when the thermostat is calling for heating or cooling to occur. In the Heat mode switch position, a flame will be present on the screen. A steady flame means that the thermostat is not calling for your heating system to run, while a flashing flame means that your heating system should be currently running. In the Cool mode switch position, a snowflake will be present on the screen. A steady snowflake means that the thermostat is not calling for your cooling system to run, while a flashing snowflake means that your cooling system should be currently running.

EMERGENCY HEAT: (Heat Pump Configuration Only). While in normal Heat mode, one single press of the EMER button will activate Emergency Heat mode. While in Emergency Heat, the top of the screen will change from

“Heat Mode” to show “Emer Heat”. A single press of the EMER button again will end Emergency Heat, and return back to normal Heat mode. If a power loss occurs while in Emergency Heat mode, the thermostat will continue to remain in Emergency Heat mode even after the power comes back on.

Emergency Heat mode will prevent the first stage of your heat pump system from turning on, and use only the “W2” heat terminal (Auxiliary Heat) as the primary heating source. This will not only prevent the heat pump from wasting energy if outdoor temperatures are too low to support efficient operation, but it could also prevent damage to the heat pump if outside temperatures are below the manufacturer’s recommendations. As every heat pump has different operating characteristics, you should refer to your heat pump literature to determine when to disable the heat pump and run in

Emergency Heat mode.

21

LCD DISPLAY BACKLIGHT: The display screen is lighted to assist viewing at nighttime, or in locations with low light levels. A press of any area on the touch panel will light the display for approximately 10 seconds. Any screen presses that occur while the light is on will reset the 10-second timer, causing the screen to remain illuminated for an additional 10 seconds.

TEMPERATURE OVERRIDE: While in the Normal Run screen, the set temperature can be temporarily changed by pressing the Set Temperature digits, then pressing the UP or DOWN buttons. The set temperature will return to the programmed value stored in memory when the start time of the next upcoming program period is reached (Morn, Day, Eve, Nite). While a

Temporary Override is in effect, the words “HEAT OVRRIDE” or “COOL

OVRRIDE” will be shown in the display screen. An Override may be cancelled by either pressing the HOLD button two times, or by moving the mode switch to OFF, pausing briefly, then switching back to the HEAT or

COOL position. When in the Normal Run mode, the display should say either

“HEAT MODE” or “COOL MODE”.

MINIMUM RUN TIME: The thermostat has a default internal time delay of 5 minutes between load-on and load-off activations to prevent heating or cooling system damage, which can occur from very frequent cycling. If heating or cooling does not turn on right away with a manual change in set temperature, please wait at least 5 minutes and the system should resume normal operation.

TEMPERATURE HOLD: A Temperature Hold is used for maintaining a fixed set temperature. Once a Hold is initiated, the thermostat will maintain the set temperature indefinitely. A Hold may be used for days, weeks, or even months at a time, as long as the thermostat has adequate power. To enter

Hold mode: press the HOLD button one time and the words “HEAT HOLD” or

“COOL HOLD” will appear in the display. To cancel a Hold, press the HOLD button one more time. If a mains power failure occurs during a Temperature

Hold, the thermostat will continue to remain in Hold mode even after the power comes back on.

NOTE: If you plan to leave the thermostat in Hold mode for an extended duration (unattended), it is advisable to install new Energizer ® or

DURACELL ® "AA" size alkaline batteries prior to leaving to ensure reliable operation of your heating and cooling system.

22

STATIC NOTICE: This thermostat is protected against normal static electric discharges, however to minimize the risk of damaging the unit in extremely dry weather, please touch a grounded metal object before touching your thermostat.

TEMPERATURE PROGRAMS:

By default, this thermostat has 4 separate program periods for both Heat and

Cool mode, they are: MORN, DAY, EVE, and NITE. Each period ends at the start time of the following period. The heat programs are set in HEAT mode, and the cool programs are set in COOL mode.

NOTE: If the thermostat is configured to use only 2 periods per day instead of 4 (HARDWARE SETUP OPTIONS), the thermostat will only use the DAY and NITE periods. The MORN and EVE periods will not be visible on the screen.

The following examples are shown using Heat mode. Programming in Cool mode is done in the same exact manner with the System Mode switch in the

Cool position.

SET TEMPERATURE PROGRAMS: Press the MENU button, then press the

SCROLL button until “SET/REVIEW HEAT PROGMS” is shown, then press the

OK button to enter the programming screen. Use the UP and DOWN buttons to adjust the start time for the MORN period, then press the NEXT button to advance. Use the UP and DOWN buttons to adjust the set temperature for the MORN period, then press the NEXT button to advance. Now adjust the start time and set temperature for the DAY period, pressing the NEXT button after each to advance. Continue with these same steps to adjust the start times and set temperatures for the EVE and NITE program periods.

When the NITE period is finished the thermostat will advance to Tuesday, with the MORN period start time flashing. Perform the same steps that you used for setting the Monday periods, pressing the NEXT button to advance through each flashing value.

PROGRAM COPY FEATURE: The Copy feature allows you to copy all of the program information from any one single day, to any other day of the week.

To copy heat programs, the thermostat must be in Heat mode, and to copy cool programs, the thermostat must be in Cool mode. Emergency Heat (heat pump configurations only) uses the Heat temperature program. While in a temperature programming screen, press the “COPY” button one time. The

23

words “COPY PROGRAM” will flash briefly at the top of the screen, followed by “FROM” and “TO”. Under the word “FROM” will be a flashing day of the week. Using the UP and DOWN buttons, select the day that you want to copy from. Press the NEXT button one time. Your copy from day should now be on steady with the day under the word “TO” flashing. Use the UP and DOWN buttons to select the day that you would like to copy to. A single short press of the COPY button will perform the copy, and the day flashing under the word “TO” will have advanced to the next following day. You may continue to perform short single presses of the COPY button to keep copying from the original source day to the remaining days, one after the other. Specific days may be skipped by pressing the UP button, to advance past them while they are flashing under the word “TO”. Press the EXIT button to return to the

Normal Run screen.

ADVANCED FEATURES:

TEMPERATURE SWING SETTING, OFFSET SETTING, AND TEMPERATURE

CALIBRATION:

NOTE: The Swing setting, Offset setting, and Calibration settings need to be performed in a timely manner, as the thermostat will timeout and automatically exit these adjustment screens after approximately 10 seconds without a button press.

SWING DESCRIPTION: A thermostat works by turning your heating or cooling system on and off whenever the room temperature varies from the desired set-point temperature. The amount of this variation is called the

Swing. Generally your system should cycle on about 3 to 6 times per hour.

A smaller swing number makes the system cycle more frequently, so the room temperature is more precise and constant. A larger swing number will make the system remain on for a longer duration each time and decreases the number of cycles per hour. There is only one Swing setting, and this determines the cut-in and cut-out points for both the first and second stages

(if present), in both Heat mode and Cool mode. The swing setting range is between #1 and #9 (0.25°F to 2.25°F, in 0.25°F degree increments (or 0.14°C to 1.25°C, in 0.14°C degree increments for Celsius)). Swing number 1 is the default setting.

OFFSET DESCRIPTION: This setting is shown as a number of degrees, and is similar in nature to the Swing however this only effects the operation of the second (auxiliary) heating stage, if present. The setting range for Offset is

24

from 0°F to 9°F degrees (0°C to 5°C degrees). When set to 0 degrees, the second heating stage is completely disabled while in regular Heat mode

(Emergency Heat mode will still function for heat pump configurations). The

Offset value will determine the number of degrees from the set point that will be required for the second heating stage to turn on. This setting can be used to conserve energy in situations where the second heating stage is more costly to operate when compared to the first stage.

TEMPERATURE CALIBRATION DESCRIPTION: The internal temperature sensor in this thermostat is accurately calibrated at the factory, and in most cases, alterations to this setting should not be needed. The Temperature

Calibration feature allows you to manually offset the measured temperature by as much as plus or minus 5°F (3°C) degrees from its original value. This feature can be useful to match or synchronize this thermostat to another one or more, if multiple thermostats are used in the same home.

TO CHANGE THE SWING, OFFSET, AND CALIBRATION: Press the MENU button, then press the SCROLL button until “SET/REVIEW SWING VALUE” is shown on the screen, then press the OK button. The words “ADJUST VALUE

SWING” will appear at the top of the screen, along with a single flashing digit. Use the UP and DOWN buttons to change the number value from #1 to

#9. Press the NEXT button to accept the Swing setting and proceed to the

Offset setting.

After the Swing value has been accepted, the words “ADJUST VALUE

OFFSET” will appear at the top of the screen, along with a single flashing temperature digit. Use the UP and DOWN buttons to change the number value between 0°F and 9°F degrees (0°C to 5°C). The 0° (zero) degree setting will disable the 2nd heating stage while in regular Heat mode. Press the NEXT button to accept the Offset setting and proceed to the Calibration setting.

After the Offset value has been accepted, the words “ADJUST VALUE CAL” will appear at the top of the screen, along with a single flashing temperature digit. Use the UP and DOWN buttons to change the number value between

–5°F and +5°F (–3°C and +3°C). The 0° (zero) degree setting is the default value, and will not alter the displayed room temperature from the measured reading. Press the NEXT button to accept the Calibration setting and return back to the Swing setting. You can keep pressing the NEXT button to review your three setting values, or press the EXIT button to return to the Normal

Run screen.

SETBACK FEATURE: The setback feature is similar to both a Temperature

Override and a Temperature Hold, in that both are used to maintain a fixed set temperature instead of following a programmed daily routine. A Setback can be considered the same as a Temperature Override, which can last for a longer duration that you can adjust from 1-12 hours, or 1-30 days. By default, when a Setback is activated in Heat mode, the set temperature used

26

will be 5F (3C) degrees lower than the current set temp. For Cool mode, the set temperature used will be 5F (3C) degrees higher than the current set temp.

NOTE: The Setback settings need to be performed in a timely manner, as the thermostat will timeout and automatically exit these adjustment screens after approximately 10 seconds without a button press.

TO START A SETBACK: Press the MENU button, then press the SCROLL button until “TEMPERATURE SETBACK” is shown, then press the OK button.

The words “OVERRIDE LEFT” will appear at the top of the screen, along with two digits and the word “HRS”. Use the UP and DOWN buttons to set the duration for how long you would like to maintain a fixed set temperature

(from 1 to 12 hours). If you would like to set the duration for longer than 12 hours, keep pressing the UP button. The display will change from “HRS” left to “DAYS” left, with an available duration of 1 to 30 days. Once you have selected your desired Setback duration, press the NEXT button to advance.

The display will change from “OVERRIDE LEFT” left to “OVERRIDE

TEMPERATURE”. Use the UP and DOWN buttons to select your desired Set

Temperature that will be used during the Setback duration. Once complete, press the NEXT button to accept the setting and return to the Normal Run screen.

TO CANCEL A SETBACK: A Setback can be cancelled by either pressing the

HOLD button two times, or by moving the mode switch to OFF, pausing briefly, then switching back to the HEAT or COOL position. When in the

Normal Run mode, the display should say either “HEAT MODE” or “COOL

MODE”.

TEMPERATURE LIMIT STOPS: There are two independent set temperature limit stops: a maximum heat set temperature, and a minimum cool set temperature. These stops do not prevent a user from performing normal actions like Temperature Override or Hold. The Heat Limit Stop prevents the set temperature from being adjusted higher than the heat limit setting. The

Cool Limit Stop prevents the set temperature from being adjusted lower than the cool limit setting. Each of these temperature stops is user adjustable in one-degree increments, and these settings are protected by a selectable 2digit code to prevent unauthorized tampering. By default, this 2-digit code is

“00”, and the temperature stops can be used as-is with this code.

NOTE: The Temperature Limit Stop settings need to be performed in a timely manner, as the thermostat will timeout and automatically exit the setting screens after approximately 10 seconds without a button press.

The following examples are shown for setting the maximum set temperature for Heat mode. Setting the Temperature Limit Stop for Cool mode is done in the same exact manner with the System Mode switch in the Cool position, and instead you will be setting the minimum set temperature for cooling.

Once a Temp Stop Lock Code has been selected, this same code is used for both Heat and Cool temp stops.

TO SET THE TEMPERATURE LIMIT STOP: Press the MENU button, then press the SCROLL button until “SET HEAT TEMP STOP” is shown, then press the

OK button. The words “ENTER CODE” and “TEMP STOP” will appear at the top of the screen, along with two digits at the left. Use the UP and DOWN buttons to enter the current Temp Stop Lock Code (“00” by default). Press the NEXT button to advance. If the code entered does not match the current

Temp Stop Lock Code, the words “WRONG CODE” will flash briefly, and you may try to enter the correct code again. If the current code has been entered correctly, you will have the ability to change the desired Temp Stop Lock

Code to something else. The words “SET CODE” and “TEMP STOP” will appear at the top of the screen, along with two digits at the left. Use the UP and DOWN buttons to enter the desired Temp Stop Lock Code to be used, and press the NEXT button to advance.

The words “SET HEAT RANGE STOP” will appear at the top of the screen, along with two large temperature digits in the middle. Use the UP and

DOWN buttons to adjust the desired maximum heat set temperature value (or minimum set temperature value for Cool mode). Once complete, press the

NEXT button to accept the setting and return to the Normal Run screen.

IF YOU FORGET YOUR TEMPERATURE STOP LOCK CODE: The code can be reset to the factory default “00” by performing the following steps. Start with the System Mode switch in either the Heat or Cool positions, then change to the OFF position. Press and hold the HOLD, NEXT, and OK buttons all at the same time for at least 10 seconds. The screen will briefly show

“00” on the screen to confirm that the Temp Stop Lock Code has been successfully reset to the factory default of “00”.

KEYPAD LOCKOUT: You can lock the touch-panel buttons to prevent unauthorized tampering of your thermostat settings.

NOTE: These keypad lock instructions need to be performed in a timely manner, as the thermostat will timeout and automatically exit the keypad lock screens and return to the Normal Run screen after approximately 10 seconds without a button press.

TO LOCK THE KEYPAD: The System Mode switch must be in either the Heat or Cool position. Press the MENU button, then press the SCROLL button until “SET KEYBOARD LOCK CODE” is shown, then press the OK button. The words “ENTER CODE” will appear at the top of the screen, along with four digits at the left. Select a 4-digit code that you would like to use for locking the thermostat. Press the UP and DOWN buttons to change each digit individually, using the NEXT button to cycle through which digit is selected.

Pressing the OK button will lock the thermostat touch panel using the 4-digit code that is shown on the screen, and return to the Normal Run screen with a padlock shown to confirm that the thermostat is now locked.

TO UNLOCK THE KEYPAD: Press the padlock icon, and the words “UNLOCK

KEYBOARD?” will appear at the top of the screen. Press OK to proceed with entering the unlock code (or press the EXIT button to cancel). The words

“ENTER CODE” will appear at the top of the screen, along with four digits at the left. You will need to enter the proper unlock code that was used for initially locking the thermostat. Press the UP and DOWN buttons to change each digit individually, using the NEXT button to cycle through which digit is selected. With the correct lock code entered on the screen, pressing the OK button will unlock the thermostat. If the code entered does not match the current keypad lock code, the words “WRONG CODE” will flash briefly, and you may try to enter the correct code again.

IF YOU FORGET YOUR KEYPAD LOCK CODE: The following steps can regain access to the thermostat. Remove the front portion of the thermostat from the wall, and briefly press the “HW RST” HARDWARE RESET button on the thermostat circuit board. More information about the use of this button is described later in this section.

AIR FILTER MONITOR: In most systems that use a blower fan and air ducts, there is an air filter that is either replaceable or requires cleaning. The filter is usually located in the air handler, where the blower fan is. This thermostat feature assists you with keeping track of proper maintenance and/or periodic replacement intervals for your system’s filter.

29

The Air Filter Monitor counts the duration of filter usage that has occurred, since the last time the Filter Monitor has been reset. This feature is for information purposes only, and does not affect the operation of your heating or cooling equipment, or the thermostat. When the filter usage duration has expired, the words “CHANGE FILTER” will appear at the top of the display screen, alternating with the current DAY and PERIOD.

TO ACCESS FILTER INFORMATION: Press the MENU button, then press the

SCROLL button until “SET/REVIEW FILTER USAGE” is shown, then press the

OK button. The words “FILTER USAGE COUNT” will appear at the top of the screen, along with the total number of hours that have elapsed since the last time the filter counter was reset. Press the NEXT button to advance.

The words “FILTER USAGE RESET?” will appear at the top of the screen. To reset the filter counter to the start of the current limit setting press the OK button. Press the NEXT button to advance.

The words “ADJUST VALUE FILTER LIMIT” will appear at the top of the screen. This shows the current setting value for how many filter run time hours can elapse before showing “CHANGE FILTER” in the Normal Run screen. The adjustment range for this setting is from 0 hours to 2000 hours, with 720 hours as the default. A filter limit setting of 0 (zero) hours will disable the filter monitor feature. Once complete, press the EXIT button to save all settings and return to the Normal Run screen.

NOTE: Air filters are sold based upon how many days they are rated for. One day of filter run time is actually considered only 8 hours (not a full 24, since your heating and/or cooling system only runs for approximatly one third of the time). For a “90-day” filter, use a limit setting of 720 hours should be used, and for a “30-day” filter, a limit setting of 240 should be used.

ENERGY USAGE MONITOR: Your thermostat contains a timer, which records the amount of “on-time” for your heating and cooling systems. There are three records that can be displayed for both Heat and Cool modes:

1) The amount of system run time so far for today.

2) The amount of system run time for yesterday.

3) The total cumulative system run time since the timer was reset.

The Heat Energy Usage information is shown while the System Mode switch is in the Heat position, and the Cool Energy Usage information is shown while the System Mode switch is in the Cool position. The following

30

examples are shown for viewing the Energy Usage while in Heat mode.

Viewing the Cool mode information is done in the same exact manner in Cool mode.

TO VIEW THE ENERGY USAGE TIMERS: Press the MENU button, then press the SCROLL button until “REVIEW HEAT ENERGY USAGE” is shown, then press the OK button. The words “TODAYS ENERGY USAGE” will appear at the top of the screen, along with the amount of heating system runtime

(displayed as “HH:MM”, for hours and minutes). Use the NEXT button to cycle between Today’s Usage, Yesterday’s Usage, and the Total Cumulative

Usage for heat mode. NOTE: For the Total Cumulative Usage, the timer will record up to a maximum of 99 hours and 59 minutes, then the display will change to “HHHH” for hours only, without the colon in the center.

Pressing NEXT after the Total Cumulative Usage will show the words “TOTAL

USAGE RESET?” at the top of the screen. Pressing OK at this screen will clear the Heat Energy Usage timer, and start back at 0 (zero). Press the EXIT button to return to the Normal Run screen.

HARDWARE RESET: The Hardware Reset button (labeled

“HW RST”) is a small round push button that is located towards the right side of the circuit board, just below the battery holder. Pressing this button will cause the LCD

HW

RST display screen to become fully populated, the heating and cooling load relays to cycle off, read the position of the

Hardware Setup Option switches, and will perform an internal system check of the thermostat components. If your thermostat appears to be acting in an erratic manner, pressing the Hardware Reset button may remedy this behavior. The temperature programs are not erased when a hardware reset is performed, however the clock will have to be changed to match the current day and time.

SOFTWARE RESET: The Software Reset button (labeled

“SW RST”) is a small round push button that is located towards the right side of the circuit board, just below the battery holder. A Software Reset is used to erase all

SW

RST heating and cooling temperature programs, and any useradjustable software values such as: Swing, Offset, and

Calibration, to their original factory default values. To perform a Software

31

Reset, press and hold the Software Reset button for at least 5 seconds. The

LCD display screen will become fully populated, then return to normal. The thermostat will still retain the current day and time even after a Software

Reset has been performed.

COMPRESSOR PROTECTION BYPASS: This optional feature permits the installer or service technician to temporarily disable the built in compressor protection delays. This is most useful for diagnosing and testing the heating and cooling systems after installation is complete, and should not be used during normal operation. To activate this feature, start with the System

Mode switch in either the Heat or Cool positions, then change to the OFF position. Press and hold the OK button for at least 5 second. The thermostat will give a single beep sound to confirm that this feature has been activated. All compressor protection delays (in all modes of operation) will be disabled for 5 minutes. After the 5-minute duration has expired, the thermostat will return to normal operation automatically.

BATTERY REPLACEMENT:

This thermostat is powered by two “AA” Alkaline batteries. The batteries should be replaced AT LEAST once per year to ensure reliable operation (or sooner, if the “LO-BATTERY” icon appears at the bottom of the display screen). The batteries are located on the back of the thermostat, at the top of the circuit board. The front portion of the thermostat can be removed from the back half by pulling straight outwards on the top and bottom of the thermostat housing, at the large indentations that are present in the center of the top and bottom edges.

When installing new batteries, we recommend using only brand new

Energizer ® or DURACELL ® , “AA” size alkaline batteries. Please observe the polarity markings shown in the battery compartment to ensure proper installation. When finished, line up the front of the thermostat to the base, and firmly press together to securely latch the front and back halves together properly.
