IMPORTANT
2, Read the entire installation section of this Owner’s Manual thoroughly before you
begin to install or operate your Thermostat.
Figure 1. Electric/Gas Switch (Fan Option)
This thermostat is configured from the factory to operate a heat/ cool, fossil fuel (gas, oil,
etc.), forced air system. It is configured correctly for any system that DOES NOT require
the thermostat to energize the fan on a call for heat. If you system is an electric heat or
heat-pump system that requires the thermostat to turn on the fan on a call for heat,
locate the ELEC/GAS switch on the back of the thermostat (see fig. 1) and switch it to
the ELEC position. This will allow the thermostat to energize the fan immediately on a
call for heat. If you are unsure if the heating/ cooling system requires the thermostat to
control the fan, contact a qualified heating and air conditioning service person. When the
thermostat is configured for Heat Pump, the thermostat will always power the circulator
fan on a call for heat in the HEAT mode. The ELEC/GAS switch must be set to match the
type of Auxiliary heat your system uses for proper operation in the EMERgency mode.
All wiring diagrams are for typical systems only. Refer to equipment manufacturers’
instructions for specific system wiring information.
Attach Thermostat Base to Wall
1. Remove the packing material from the thermostat. Gently pull the cover straight off the
base. Forcing or prying on the thermostat will cause damage to the unit.
2. Connect wires beneath terminal screws on base using appropriate wiring schematic
(see figs. 2 through 4).
3. Place base over hole in wall and mark mounting hole locations on wall using base as
a template.
4. Move base out of the way. Drill mounting holes.
5. Fasten base loosely to wall, as shown in fig. 1, using two mounting screws. Place a
level against bottom of base, adjust until level, and then tighten screws. (Leveling is for
appearance only and will not affect thermostat operation.) If you are using existing
mounting holes, or if holes drilled are too large and do not allow you to tighten base
snugly, use plastic screw anchors to secure subbase.
6. Push excess wire into wall and plug hole with a fireresistant material (such as
fiberglass insulation) to prevent drafts from affecting thermostat operation.
This thermostat can be used for conventional or heat pump system,
Please configure the thermostat according to Configuration Menu
before operation.
REMOVE THE MYLAR LABEL FORM THE LCD DISPLAY WINDOW.
INSTALLATION
3, All installation is normally performed at your thermostat.
ARMCHAIR PROGRAMMING
4 You can program your thermostat before installation by inserting the batteries and
following the instructions starting configuration menu.This can be done while you relax in
your favorite chair and is a very good way to familiarize yourself with all the functions of
your thermostat.
The following time and temperature settings are pre-programmed into the thermostat:

COMPRESSOR PROTECTION
5 The thermostat provides a 4 minutes delay after shutting of the heating or cooling
system before it can be restarted. This feature will prevent damage to your compressor
caused by rapid cycling. Note that this delay also applies to the heating system control. It
does not provide a delay when there are power outages.you can select the function on
or off at the configuration.
TEMPERATURE RANGE
6, This thermostat can be programmed between 45˚F and 95˚F (7˚C and 35˚C).
However, it will display room temperatures from 30˚F to 99˚F (0˚C and 37˚C). “HI” will be
displayed if the temperature is higher than 99˚F (37˚C), and “LO” will be displayed if the
temperature is lower than 30˚F (0˚C).This thermostat will automatically cutoff in Heat
mode if the temperature rises above 95˚F (35˚C), and automatically cutoff in Cool mode
if the temperature drops below 45˚F (7˚C).
NOTE: if the thermostat measure a temperature over 99˚F(37 ), ”HI” will be displayed
on the LCD. if the temperature is below 32˚F(0 ). and ”LO” will be displayed on the
LCD,.
POWER FAILURE
7 Whenever the main power is interrupted or fails, the battery power retains and
current time. This thermostat has permanent memory, although you will have to reset
your clock when there are power outages.
POWER SUPPLY
8 The thermostat shall be powered by 24 VAC and with batteries as backup.
BATTERY WARNING
9 Fresh alkaline batteries should provide about one year of service. However, when the
batteries become drained, “BATT” will alternate on the display with the current time.
When this message occurs, install 2 new AA batteries, You have approximately 1 minute
to change the batteries and keep thermostat’s clock and program settings. Once the
batteries have become too low to ensure proper operation, your system will be turned off,
and the display will be cleared except for “BATT” flashing on the LCD display.
CAUTION: Once only the “BATT” only display occurs, the thermostat is shut down, and
your system will no longer operate. In this condition, there is no temperature
control of your dwelling. NOTE: The backlight will not function when the
thermostat is in low battery condition.
NOTE: If you plan to be away from the premises over 30 days, we
recommend that you replace the old batteries with new alkaline batteries prior to
leaving.

Auto Programming
Studies conducted by the Department of Energy estimate that
setting your thermostat back 10˚F (6 ) for two 8-hour periods
during winter can reduce your fuel bill by as much as much as
33%. By setting your thermostat up 5˚F (3 ) for tow 8-hour
periods during summer you can reduce your fuel bill up to 25%.
Your thermostat is capable of holding up to 4 separate programs
for each day ofthe week. You can program all weekdays, Monday
to Friday, to the same 4 programs as show in the table, or each
weekday can have a different set of 4 programs. Similarly
weekend programs, Saturday and Sunday, can be the same 4
programs or each weekend day can have a different set of 4 programs.

change between Heating and Cooling systems, depending on your program. We
recommend keeping your programmed heating and cooling temperature at least 4˚F
(2˚C) apart to allow the Auto Season Changeover to occur when the appropriate
temperature span has been reached. However, if your heating and cooling programs set
temperatures are close, there is a built-in program to prevent the thermostat is in
Temporary, a Designated Day Override or Permanent Override, as these overrides are
energy saving settings. Auto Season Changeover will still function in Home Today mode,
as this is a comfort setting.
For example, you may have the following temperatures programmed at a given time:
Heat Set Temp=68˚F, Cool Set Temp=78˚F
If the room temperature rises above 78˚F, then the thermostat will automatically change
to cool mode and turn on the air conditioner.
Likewise, the thermostat will automatically change to heart mode and turn on heat when
the room temperature falls below 68˚F.
HOME TODAY
This patent pending feature allows you to quickly and Temporarily Override your energy
saving program setting on days when you are normally away from home with one key
press.
Press to enter the Home Today override .The highest
HOLD
/ RUN program temperature for today will be selected from your
programs in Heat mode and become the set
temperature.(In Cool mode ,Home Today will select the
lowest program temperature for today to be the set
temperature.)
The display will alternate between “HOME” and the current time.
When pressed during the day, the thermostat will remain in Home Today mode
HOME
TODAY until the first program of the next day.
If the system is changed between Heat and Cool modes (either manually or by
Auto Season Changeover) during the “Home Today” override period, the setpoint
temperature will be automatically update. It will automatically change from the lowest
cool program setpoint to the highest heat program setpoint.
Press to exit Home Today mode before the schedule ending time. ”HOME” is
HOLD
/ RUN
no longer displayed on the LCD screen, and the thermostat returns to the current
program.
You can manually change the setpoint temperature while in Home Today mode.
Refer to the Temporary Manual Override instructions .Manually changing the set
temperature while in Home Today mode will not affect the Home Today ending
time, However, the set temperature will not change automatically with a manual
or Automatic change between heating and cooling.
Energy Monitor
The Energy monitor feature measures and stores the
amount of time the heating and air conditioning system

operates. Usage can be display for Today (since 12 am),
Yesterday, This Week (since Monday), Last Week (last
M
Monday through Sunday), and Total (up to 999 Hrs). By
monitoring your energy usage, you see how much the set-back periods are
saving, and you can test program adjustment to save even more. To review
energy usage, press to cycle through Today, Yesterday, this Week, Last Week,
and Total. Press again to return to normal mode, or wait 15 seconds for the
display to return to normal mode .You can also return to normal mode at any time
by pressing RUN.
For example: This LCD display shows Today’s usage to be 10 Hours, 26

Press and hold for 3 seconds to reset the Energy Monitor’s counters.
The display will blink, and counters will be cleared to zero.
NOTE: Clearing the Energy Monitor counter will also clear the Filter Monitor counter , as
Filter usage and Total Energy usage are the same. Also, clearing the filter Monitor
counter will clear ALL Energy Monitor counters as well.
Filter Monitor
Your thermostat also keeps a record of the number of hours
your filter has been in use. To maximize your system’s
performance and energy efficiency,
change or clear your filter regularly.
When the total system run time for heat and cool reaches 500
hours, you need clean or change your system’s filter, “FILT” will
continue to flash until the counter is set back to zero.
Press to review total filter usage. The display will blink “FILT”

The Filter Monitor will display up to 999 hours and 59 minutes of
usage. In this example, the counter is at 410 Hours, 26 minutes.
To reset the Filter Monitor counter, depress FILTER for 3
seconds. The display will blink, and the counter will be reset to zero.
NOTE: Clearing the Filter Monitor counter will also clear ALL Energy Monitor counters,
as Filter usage and Total Energy usage are the same. Also, clearing the Energy Monitor
counters will clear the Filter Monitor counter as well.
Auto Recovery
Auto Recovery calculates how early to turn your system back on, so that the room
temperature is already comfortable by the start of the comfort temperature program
period. Auto Recovery work’s in both Heat and Cool modes.
When the thermostat is in Auto Recovery mode, the display will
alternate “RECO” with time, and the program indicator will flash.
Auto Recovery can be disabled by sliding the Recovery switch
on the circuit board to disable.
Auto Recovery will not operate if Permanent hold or Temporary hold is in operation.
Auto Recovery can be canceled manually if HOLD is pressed during the recovery
process.
Auto Recovery will be canceled and change to next period.
Details of Auto Recovery Operation:
Auto Recovery can be disabled by sliding the Recovery switch on the circuit board to
the DISABLE position.
Today is in operation.
Auto Recovery can be canceled manually if HOLD is pressed during the recovery
process. If a recovery process is canceled manually then the recovery process will not
start again until the next program period starts (an exception is that if time or program is
changed then the thermostat will check Auto Recovery conditions immediately).
Auto Recovery will be canceled and change to Home Today mode if HOME TODAY is
pressed during the recovery process.
Keyboard lock
The keyboard can be locked to prevent unauthorized changes to
the thermostat.
To lock or unlock the keyboard, press and hold hold/run Key for 3
seconds. The keyboard is locked. when LOCK appears on the

Backlighting
Your thermostat has an electroluminescent lamp that backlights the display for easy
viewing in the dark.
When any key is pressed the display is illuminated.
The display will remain illuminated for 8 seconds after the last key is pressed. This
allows the light to stay on if you need to operate several keys.
NOTE: If the thermostat is in Low Battery warning condition, the backlight will not
operate. Replace with 2 new AA alkaline batteries to restore the Backlight function.
Low Battery Warning
Your thermostat has a two-stage lower battery warning system.
When the batteries are first detected to be weak, the first stage
low battery warning is indicated
by “BATT” flashing on the LCD display. At your earliest
convenience, you need to replace the batteries with 2 new AA
alkaline batteries.
When the batteries become too weak for normal operation, the
thermostat enters the second stage low battery warning which
shuts down the thermostat. In this condition, “BATT” flashes
alone on the display, and the thermostat will turn your system Off.
Your system will remain shut-off until the batteries are replaced.
NOTE: The thermostat will still keep the current Set Temperature and Filter run time in
memory until new batteries are installed. After confirming that new batteries have been
inserted, the thermostat will return to normal operation.
