Congratulations!
Your new thermostat will provide years of reliable service. By saving energy, your
thermostat will pay for itself during its first season of use. Thanks you for buying our
product!
Please read this manual for complete instructions on installing and operating your
thermostat. If you require further assistance, please feel free to contact us
IMPORTANT INFORMATION
1.
This thermostat will NOT control 110/220V baseboard electric heating systems.
2. Temperature Range
This thermostat can be programmed between 41
˚
F and 95
˚
F (5
˚
C and 35
˚
C) in HEAT
mode, 45
˚
F and 99
˚
F (7
˚
C and 37
˚
C) in COOL mode. However, it will display room
temperatures from 32
˚
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
32
˚
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).
3. Compressor Protection
This thermostat provides a 4 minutes delay after shutting off the cooling system before it
can be restarted. This feature will prevent damage to your compressor caused by rapid
cycling. It does not prevent a rapid compressor restart due to short power outages.
4. Battery Warning
Two fresh AAA alkaline batteries should provide well over one year of service. However,
when the batteries become drained, the Low Battery Indicator will flash on the display.
When this message occurs, install new alkaline batteries. 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 flashing Low Battery Indicator on the LCD display.
CAUTION:
When only the Low Battery icon flashes on the display, 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 battery with new alkaline battery prior to leaving.
5.Power supply
The thermostat shall be powered by 24 VAC and with battery as backup.

INSTALLATION
What You Need
This thermostat includes two #8 slotted screws and four wall anchors for mounting. To
install your controller, you should have the following tools and materials.
■
Slotted Screwdriver(s)
■
Small Philips screwdriver
■
Hammer
■
Electric drill and 3/16” bit
■
Two 1.5V (AAA) size alkaline battery (included)
CAUTION:
To prevent electrical shock and/or equipment damage, disconnect electric power
to system at main fuse or circuit breaker box until installation is complete.
Before removing wires from old thermostat's switching subbase, label each wire with the
terminal designation it was removed from.
1. Shut off electricity at the main fuse box until installation is complete. Ensure that
electrical power is disconnected.
2. Remove Old Thermostat: A standard heat/cool thermostat consists of three basic
parts:
a. The cover, which may be either a snap-on or hinge type.
b. The base, which is removed by loosening all captive screws.
c. The switching subbase, which is removed by unscrewing the mounting screws that
hold it on the wall or adaptor plate.
3. Remove the front cover of the old thermostat. With wires still attached, remove wall
plate from the wall. If the old thermostat has a wall mounting plate, remove the
thermostat and the wall mounting plate as an assembly.
4. Identify each wire attached to the old thermostat.
5. Disconnect the wires from the old thermostat one at a time. DO NOT LET WIRES
FALL BACK INTO THE WALL.
6. Install new thermostat using the following procedures.
WARNING
Does not use on circuits exceeding specified voltage. Higher voltage will damage
control and could cause shock or fire hazard. Do not short out terminals on gas
valve or primary control to test. Short or incorrect wiring will damage thermostat
and could cause personal injury and/or property damage.
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 fig 4 through 6 and fig 1 ).
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 figs2 and figs3 . using four mounting screws.
6. Push excess wire into wall and plug hole with a fireresistant material (such as
fiberglass insulation) to prevent drafts from affecting thermostat operation.

Install AAA batteries
• The thermostat requires 2 AAA batteries to operate .
• Install 2 AAA alkaline batteries according to the polarity noted in the compartment. LCD
segments will go on.
NOTE: Replace the batteries when this LOW battery indicator appears on the display or
once a year.
Heat Pump Terminal Outputs
Refer to equipment manufacturers' instructions for specific system wiring information.
You can configure the thermostat for use with the following heat pump system types:
Single stage compressor system;
multiple stage compressor system; gas or electric
backup. This thermostat is designed to operate a single-transformer system. If you have
a two-transformer system, cut and tape off one transformer. If transformer safety circuits
are in only one of the systems, remove the transformer of the system with NO safety
circuits. If required, replace remaining transformer with a 75VA Class II transformer. After
disconnecting one transformer, the two commons must be connected together.
Use the terminal output information below to help you wire the thermostat properly for
your heat pump system. After wiring, see CONFIGURATION section for proper
thermostat configuration.

Fan operation
The Fan mode should normally be chosen in the AUTO position. The Fan will be
turned on along with normal operation of your system. In a normal gas or oil furnace,
the Fan will not be open with the equipment. For electric heat, air conditioning, and
heat pump operation, the Fan will turn on with the system. To run the Fan on
continuously, change the Fan ON . Change the Fan Circ ,Fan runs randomly for
approximately 35% of schedule period when there is no call for cooling or heating
(programmable for all schedule periods).

Auto System
When the System Selector is in AUTO position , the thermostat will automatically
change between Heating and Cooling systems, depending on your setpoint. We
recommend keeping your programmed heating and cooling temperature at least 2
˚
F
(1
˚
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.
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.
