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 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.

INSTALL THERMOSTAT BASE:

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. Separate new thermostat housing using your thumb and index finger. Provide

pressure in opposite directions to the release tabs on the top of the housing,

in the directions shown in the diagram shown above.

4. 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.

5. 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 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 24-volt

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 both 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.

COMPLETE THE INSTALL:

INSTALL BATTERIES INTO THERMOSTAT: Install two brand new Energizer^®or

DURACELL^®“AA” size alkaline (only) batteries, into the thermostat’s battery

compartment. Ensure the batteries are installed in the proper direction.

FRONT PANEL ITEMS:

These items below are all located behind the door on the front of the thermostat.

To open the door, pull outwards using the small indentation in the center of the

top edge 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.

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).

MULTI-FUNCTION, SET SLIDE SWITCH: This switch provides an easy way to

quickly access the most commonly used thermostat settings. This switch has 5

individual positions, and unless a specific setting is being adjusted, this switch

should always remain in the RUN position for the thermostat to control the room

temperature. The other Set Slide switch positions are described in greater detail

in the ADVANCED FEATURES section. NOTE: this switch is only operable when the

thermostat is in “Programmable” mode. When the thermostat is used in

“Manual” control mode, all 5 of the switch positions will act like the RUN

position, except the “FILT/ENRGY” position.

SETBACK BUTTON: This button activates and deactivates the SETBACK feature,

which overrides the set temperature for an adjustable duration. This feature is

described in greater detail in the ADVANCED FEATURES section.

Download from Www.Somanuals.com. All Manuals Search And Download.

UP / DOWN BUTTONS: The UP and DOWN buttons are used to adjust any item

that can be changed by the user. Examples are the set temperatures, clock

times, and days of the week. In many cases, an item may be flashing if it can

currently be adjusted.

HOLD BUTTON: This button activates and deactivates the manual Temperature

Hold feature, and is also used for activating and deactivating the Special

Program feature. These features are described in greater detail in the

OPERATING INSTRUCTIONS and ADVANCED FEATURES sections.

COPY / EMERG BUTTON: While setting temperature programs, this button allows

you to quickly copy settings from one day to another. When in Normal Run mode,

the usage of this button varies depending upon your specific system

configuration. For heat pump systems, pressing this button enables your

emergency heat function, which is described in greater detail in the OPERATING

INSTRUCTIONS section. For conventional systems, there is no such thing as

emergency heat, so this button will have no effect.

NEXT BUTTON: This button is mostly used while setting items such as software

options, and temperature program periods. When there are several items on the

screen that can be changed, usually one of them is flashing indicating that it can

be adjusted. Pressing the NEXT button will cycle through which item is flashing.

SYSTEM CONFIGURATION AND SETUP OPTIONS:

Setup options for how the thermostat will function, along with choosing your

particular system type, are performed using a menu on the display screen.

TO ACCESS THE SETUP MENU: Move the System Mode switch into the OFF

position, and then hold down the EMER button for approximately 5 seconds until

the screen changes. The menu will always start with item #1, and is advanced to

each following item by a single press of the NEXT button. The options for each

item are changed using the UP or DOWN buttons.

ITEM #01 (CLOCK FORMAT): [12Hr, default] This displays the clock times using

standard AM and PM values. [24Hr] This displays the clock times using the

military-time format (example 22:00 hours, without using AM or PM).

ITEM #02 (TEMPERATURE SCALE): [F, default] Shows all temperature values in

Fahrenheit. [C] Shows all temperature values Celsius.

Download from Www.Somanuals.com. All Manuals Search And Download.

ITEM #03 (THERMOSTAT TYPE): [PROGRAMMABLE, default] Use this setting for

following a daily program routine. [MANUAL] This setting omits the program

routine and operates as a manual style non-programmable thermostat. This is

very basic and only shows the room temperature and set temperature on the

screen, with no clock.

ITEM #04 (PERIOD QUANTITY): [4P, default] Thermostat uses four periods per

day (called MORN, DAY, EVE, and NITE). [2P] The thermostat uses two periods per

day (called DAY and NITE).

ITEM #05 (EARLY RECOVERY): [OFF, default] Program Set Temperature values

start to occur at exactly the period start times. [ON] Early Recovery affects how

the transition occurs when changing from the NITE to the MORN period, and

when changing from the DAY to the EVE period. The thermostat calculates how

long it takes for your home to recover from a setback on a daily basis, and turns

on ahead of time in order to reach the target set point of the next upcoming

program period by the period’s start time. While in a recovery, the word

“RECOV.” will be shown on the display screen.

ITEM #06 (SYSTEM MODE): [FURN, default] This is for the majority of heating

systems that are not Heat Pumps, such as a gas furnace or hot water boiler. [HP]

Use this setting if you have a Heat Pump system, which uses the outdoor unit as

the primary heat source and may also contain an electric heating element as a

backup heat source. When set to “HP”, ensure that you have also set the

Gas/Electric circuit board option to “ELEC”, as described in the “COMPLETE THE

INSTALL” section.

ITEM #07 (FAN “G” TERMINAL OPERATION): This setting changes how your

system’s blower fan (if applicable) is controlled while the thermostat is in HEAT

or EMERG HEAT mode, when the Fan switch in the AUTO position. This setting

does not affect the fan operation while in COOL mode.

[GAS, default] The blower fan is controlled solely by the heating system itself.

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

propane, or oil furnaces, and boilers.

[ELEC] The blower fan is controlled directly by the thermostat. This setting is

required for heating systems that do not control their own fan, such as HEAT

PUMPS, and units that only have an electric-resistive heating element as the heat

source.

NOTE: If your blower fan does not operate properly after installation, try changing

the GAS / ELEC option to the “ELEC” setting.

ITEM #08 (DELAY TIME): [5, default] Thermostat waits 5 minutes before turning

the system back on after it was last run. This internal delay prevents rapid

cycling and provides equipment protection. The 5 minute setting is fine for most

applications. [2] Same operation as above but reduced to 2 minutes between

state changes.

ITEM #09, #10, #11 (SYSTEM CYCLE DURATION): These three settings will

control how frequently your heating/cooling system will be allowed to cycle ON

during room temperature control. The possible setting values for these three

items are: 60, 30, 20, 15, 12, 10, 8, and 6. Whether all three of these items are

shown, and their available values, will change depending upon what type of

heating system you have selected previously in ITEM #06.

#09 = HEAT MODE, CYCLE DURATION

#10 = COOL MODE, CYCLE DURATION

#11 = EMERGENCY HEAT, CYCLE DURATION

When the heating/cooling system turns on, it will remain running for as long as

necessary to reach and maintain your target set temperature. EXAMPLE: with an

ITEM #09 HEAT CYCLE setting of 12, the heating system will turn on

approximately 5 times per hour (turning ON once every 12 minutes). With an

ITEM #10 COOL CYCLE setting of 20, the cooling system will turn on

approximately 3 times per hour (turning ON once every 20 minutes).

ITEM #12 (STAGE-2 OFFSET): [4, default] This setting is adjusted as a number

from 0 to 9. This setting varies how low the room temperature must drop before

the second (auxiliary) heating stage becomes activated, if present. When set to 0

(ZERO), the second heating stage is completely disabled while in regular Heat

mode (however Emergency Heat mode will still function for heat pump

configurations). A lower number will make the second stage turn on sooner,

while a larger number will permit a larger decrease in room temperature to occur

before bringing on the second heating stage.

OPERATING INSTRUCTIONS:

SET DAY AND TIME: Place the Set Slide Switch into the DAY/TIME position. With

the day flashing, press UP or DOWN to set the day of the week. Press NEXT and

the clock time will start flashing. Use UP or DOWN to set the time, making sure

the AM/PM indication is correct. Holding the UP or DOWN buttons will make the

clock digits scroll rapidly. Return the Set Slide switch to the RUN position when

finished.

HEATING AND COOLING: Basic operation of your heating or cooling system can

be obtained with the Set Slide Switch in the RUN position and choosing either

HEAT or COOL on the System Mode switch. The temperature can be adjusted

using the UP and DOWN buttons. When the thermostat is first powered up, it will

follow a default temperature routine that is preset from the factory (shown

below).

NITE 10:00 PM 62 °F (17 °C) 10:00 PM 82 °F (28 °C)

EMERGENCY HEAT: (Heat Pump Configuration Only). While in normal Heat mode

with the Set Slide switch in the RUN position, one single press of the COPY/EMER

button will activate Emergency Heat mode. A single press again will end

Emergency Heat mode, and return back to normal Heat mode. While in

Emergency Heat mode, the word “EMER” will also be shown in the middle portion

of the display screen. 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.

LCD DISPLAY BACKLIGHT: The display screen is lighted to assist viewing at

nighttime, or in locations with low light levels. A press of any button on the front

panel will light the display for approximately 10 seconds. Any button 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 Program RUN mode, the set temperature can

be temporarily changed by pressing UP or DOWN. 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 word “OVERRIDE” will be shown in the display screen.

An Override may be cancelled moving the mode switch to OFF, then back to HEAT

or COOL.

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 word “HOLD” will appear in the display.

To cancel a Hold, press the HOLD button one more time. If a complete 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.

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.

SET TEMPERATURE PROGRAMS: Move the Set Slide switch to the TEMP PROG

position. Programming will start with Monday. Use the UP/DOWN buttons to

adjust the start time for the MORN period, then press the NEXT button to

advance. Use the UP/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. Return the Set Slide switch to the RUN position when you are

finished.

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. With the Set Slide

switch in the TEMP PROG position, press the COPY/EMER button one time. The

words “COPY PROG” will briefly appear on the screen and flash once, followed by

“FRM” and “TO”. Next to FRM, a day of the week will be flashing. Using the

UP/DOWN buttons, select the day that you want to copy from. Press the NEXT

button one time. Your “copy from” day should be on steady with the “copy to”

day 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/EMER button will perform the Copy,

and the flashing “copy to” day will have advanced to the next following day. You

Download from Www.Somanuals.com. All Manuals Search And Download.

may continue to perform short single presses of the COPY/EMER button to

proceed with copying to the remaining days, one after the other (specific days

may be skipped by pressing the UP button to advance past them when they are

flashing in the “copy to” location). To exit the Copy feature, and return to the

regular temperature program screen, press and hold the NEXT button for more

than 2 seconds. Return the Set Slide Switch to the RUN position when you are

finished.

ADVANCED FEATURES:

TEMPERATURE CALIBRATION: 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.

NOTE: The Temperature Calibration setting need to be performed in a timely

manner, as the thermostat will timeout and automatically exit the adjustment

screen after approximately 10 seconds without a button press.

TO CHANGE THE TEMPERATURE CALIBRATION: Ensure that the System Mode

switch is in the OFF position and the Set Slide switch is in the RUN position.

Press and hold both the UP and DOWN buttons together for at least 5 seconds.

The words “SET” and “CAL” will appear in the upper right corner of the screen,

along with a single flashing temperature digit. Use the UP/DOWN buttons to

change the number of degrees of adjustment. 0° degrees is the default value,

and means no correction is being applied. Press the NEXT button to accept the

setting.

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 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.

TO START A SETBACK: Ensure that the System Mode switch is in either the Heat

or Cool position, and that the Set Slider is in the RUN position. Press and hold

the SETBACK button for at least 2 seconds. The screen will change and show the

words “HOURS LEFT” and “OVERRIDE”, along with two digits. Use the UP/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

“HOURS LEFT” to “DAYS LEFT”, with an available duration of 1 to 30 days. Once

your desired Setback duration is shown on the screen, you can either wait for the

screen to advance forward on its own, or press the NEXT button (behind the door)

one time to jump ahead rapidly. Now use the UP/DOWN buttons to select your

desired set temperature that will be used for the Setback duration. Just like the

previous step, you can either wait for the screen to advance on its own, or press

the NEXT button to advance and return to the Normal Run screen.

TO CANCEL A SETBACK: While in the Normal Run screen, press and hold the

SETBACK button for at least 2 seconds. The word “OVERRIDE” will disappear

from the screen and the Setback will be cancelled. Moving the System Mode

switch or Set Slide switch, will also cancel a Setback.

SPECIAL PROGRAM FEATURE: The Special Program operates in the same manner

as the normal heating and cooling programs do, however the Special Program

activation is temporary, for a selected number of days (1-30). The Special

Program period times and temperatures can all be set to different values to

accommodate a wide variety of usage circumstances that may occur, such as:

being home for a couple days instead of at work, or a vacation cut short. This

feature eliminates the need to temporarily alter the normal temperature program

settings that continue to be used most of the time. The heat Special Program is

set in HEAT mode, and the cool Special Program is set in COOL mode. The

“number of days remaining” counter decrements by one day, every 12:00 AM

(Midnight).

NOTE: Just like the regular temperature programs, The Special Program has 4

separate periods for both Heat and Cool mode (MORN, DAY, EVE, and NITE). If the

thermostat is configured to use only 2 periods per day instead of 4 (HARDWARE

SETUP OPTIONS), the Special Program will only use the DAY and NITE periods.

The MORN and EVE periods will not be visible on the screen.

TO SET THE SPECIAL PROGRAM VALUES: Move the Set Slide switch to the SPEC

PROG position. The screen will display “S-PROG”. Use the UP/DOWN buttons to

adjust the start time for the MORN period, then press the NEXT button to

advance. Use the UP/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

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 2-digit 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.

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.

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 SET THE AIR FILTER DURATION: Move the Set Slide switch to the “FILT/ENRGY”

position. The words “FILTER LEFT” will be shown at the top of the display

screen. Press either of the UP/DOWN buttons to select the desired filter duration

(in days) from the following choices: OFF, 30, 60, 90, 120, 180, or 365. If the

filter duration value is set to “OFF”, then the Air Filter Monitor will be completely

disabled.

TO RESET THE FILTER USAGE COUNTER: Move the Set Slide switch to the

“FILT/ENRGY” position. The words “FILTER LEFT” will be shown at the top of the

screen. Press both the UP and DOWN buttons together, and the usage counter

will return to the beginning of the value that it originally started counting from.

Refer to the previous paragraph, should you wish to change the starting value for

the filter monitor. Return the Set Slide switch to the RUN position when you are

finished.

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.

TO VIEW THE HEAT USAGE TIMERS: Place the System Mode switch in the OFF

position, and the Set Slide switch in the FILT/ENRGY position. Press and hold the

NEXT button while sliding the System Mode switch from OFF to HEAT. The words

“TODAY USAGE” will appear at the top of the screen, along with the word “HEAT”

and the amount of heating system runtime (displayed as “HH:MM”, for hours and

minutes). Use the UP/DOWN buttons to cycle between Today’s Usage, Yesterday’s

Download from Www.Somanuals.com. All Manuals Search And Download.

Usage, and the Total Cumulative Usage. 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.

Return the Set Slide switch to the RUN position when you are finished.

TO RESET THE HEAT ENERGY USAGE: While viewing the Total Usage value, press

and hold the HOLD button for at least 4 seconds. The usage should now be

displayed as “00:00”. Return the Set Slide switch to the RUN position when you

are finished.

TO VIEW THE COOL USAGE TIMERS: Place the System Mode switch in the OFF

position, and the Set Slide switch in the FILT/ENRGY position. Press and hold the

NEXT button while sliding the System Mode switch from OFF to COOL. The words

“TODAY USAGE” will appear at the top of the screen, along with the word “COOL”

and the amount of cooling system runtime (displayed as “HH:MM”, for hours and

minutes). Use the UP/DOWN buttons to cycle between Today’s Usage, Yesterday’s

Usage, and the Total Cumulative Usage. 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.

Return the Set Slide switch to the RUN position when you are finished.

TO RESET THE COOL ENERGY USAGE: While viewing the Total Usage value, press

and hold the HOLD button for at least 4 seconds. The usage should now be

displayed as “00:00”. Return the Set Slide switch to the RUN position when you

are finished.

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 display screen to

become fully populated, the heating and cooling load relays to

HW RST

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: A Software Reset is used to erase ALL heating and cooling

temperature programs, and to return all user-adjustable software settings back

to their original factory default values. To perform a Software Reset, first ensure

that the thermostat’s Keypad Lockout is not enabled and then move the System

Mode switch to the OFF position. Press and hold the UP, DOWN, and NEXT

buttons all together for at least 5 seconds. The LCD display screen will become

fully populated (let go of buttons at this point), and than return to normal. The

clock will have to be changed to match the current day and time.

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, press and hold both the NEXT and HOLD

buttons, while also perform a single press of the Hardware Reset button (the LCD

display screen will become fully populated). Continue to hold the NEXT and

HOLD buttons until the LCD display screen returns to normal. 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

phrase “LO BATT” appears in the display screen). The batteries are located on

the back of the thermostat’s circuit board. The front portion of the thermostat

can be removed from the back half by using the tabs on the top edge of the

thermostat housing.

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.

BATTERY GRAPHIC: Anytime that batteries are

physically present in the thermostat, there will be

a visual indication of the remaining battery life

available on the thermostat’s display screen.

When brand new batteries are installed in the

battery compartment, this graphic should indicate

full battery life remaining with all bars present.

Over time, as the battery life decreases to the

point of having only 1 bar left, the Temperature

and Clock digits will start to alternate between

showing their normal content, and the words “LO

BATT”. At this point the batteries will need to be replaced as soon as practical to

avoid uninterrupted operation of your heating and/or cooling system. In most

cases, the thermostat will be capable of providing you approximately two months

of normal operation once the point of 1 bar left has been reached, and the screen

shows the words “LO BATT”.
