The Fan switch should normally be located 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 be turned on by your furnace after its
warm-up delay. For electric heat and air conditioning
operation, the Fan will turn on with the system.
To run the Fan on continuously, slide the Fan switch
to the ON position.
The System Selector switch on the front of the
thermostat determines the operating mode of the
thermostat. You may select COOL, OFF, HEAT.
NOTE: Anytime you install or remove the thermostat
from the wallplate, slide the System Selector to the
OFF position to prevent the possibility of a rapid
system On-Off.
• Press to raise the Span to 3. This setting INCREASES
the cycle time by allowing your system to run LON-
GER.
• Press and hold BOTH for three seconds. The dis-
play will ash, and SPAN will be displayed on the
LCD.
• Press to lower the Span to 1. This setting DE-
CREASES the cycle time by causing your system
to run SHORTER.
After changing or cleaning the system lter, press and hold the Filter key for 3
seconds. The display will blink, and the counter will be reset to zero.
• The display will ash
to show that you are

Selector Switches (See Figure 6)
Use the switches on the back of the thermostat and in the remote control to
match the thermostat to your system (either gas or electric), choose between
temperature readout (either Fahrenheit or Celsius), and set the remote control
address.
• Heating System Selector (HG - HE switch)
The factory position for this switch is in the “HG” position. Leave it in this
position if you have a gas furnace or an oil burner. If you have an electric
furnace, test to see whether the Heat and Fan come on as expected after
installation. If the Fan operation is normal, leave it in the “HG” position.
If the Fan does not come on within a minute of the thermostat calling for
heat, change the switch position to “HE”. The system selector has no effect
in the cooling mode.
NOTE: “HG” position is for gas and most other systems. “HE” position is
for certain electric systems having a fan relay.
• F° / C° selector (Fahrenheit / Celsius)
Your thermostat is set for F° mode from the factory. In order to change to
C° mode, slide the switch to C° and press the reset button on front of the
thermostat with a paper clip.
NOTE: Unless the reset button is pressed, the thermostat will not change
temperature mode.
• Remote Control Address
Use a pin to congure the four Remote Control Address switches.
NOTE: Write down the address to which you congure these switches, as
you will have to congure the Remote Control to the same address.
Remove the battery compartment Cover from the back of the remote control.
See Figure 7. Use a pin to congure the four remote control Address switches
to same address you gave to the thermostat.

Filter Monitor
The thermostat counts the number of hours your system’s lter has been in
use. To maximize your system’s performance and energy efciency, change or
clean your lter regularly.
When the total system run time for heat and
cool reaches 400 hours, the Filter Change
Indicator will ash as a reminder to check your
system’s lter.
NOTE: Pressing the Filter key at any time for less than 3 seconds will cause the Filter
Change Indicator to appear on the LCD. This is only to conrm key operation, and
the counter is not affected unless the key is held for greater than 3 seconds.
SPAN Setting
Your thermostat is set at the factory to cycle at 1°F (0.5°C) above and below
the set temperature. (Span = 2) This setting has been designed to provide
a comfortable room temperature under most all conditions. However, if you
nd your system cycling too fast or too slow, then the Span can be adjusted
to modify the cycle time.
The Span settings remain the same for both HEAT and COOL, and can be
changed in any System Switch position.
When batteries are installed in the thermostat, or the Reset key is pressed, the
Span is reset back to setting 2.
Low Battery Warning
Your thermostat has a two-stage low battery
warning system. When the batteries are rst
detected to be weak, the rst stage low battery
warning is indicated by battery symbol ashing
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 nor-
mal operation, the thermostat enters the second
stage low battery warning which shuts down
the thermostat. In this condition, “BATT” ashes
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 conrming that new
batteries have been inserted, the thermostat will return to normal operation.
Error Mode
If the thermostat is unable to control your sys-
tem due to an unexpected battery problem,
the thermostat will enter Error Mode. In this
condition, the thermostat ashes “Er” on the
LCD display, and shuts off your system.
To correct this problem, replace the batteries with 2 new AA alkaline batteries,
even if you have recently replaced them. Next, use a paper clip to press the
RESET button next to the keypad. You will need to reprogram your thermostat
and conrm normal operation.
If Error Mode returns, please call Technical Support at
1-888-830-1326 for further information.
Remote Operation
You can use the remote control (12 volt battery not included) that came with
your thermostat to adjust the temperature setting. Press the “+” side of the
remote button to raise the setting one degree, and press it twice to raise the
setting two degrees. The “+” side of the button will glow red each time you
press it. Press the “–” side of the remote button to lower the setting one degree,
and press it twice to lower the setting two degrees. The “–” side of the button
will glow blue each time you press it. See Figure 8.
NOTE: You can not change your thermostat’s setting by more
than two degrees in either direction by using the remote control.
If you change the setting by two degrees, you must wait until
the room temperature arrives at the new setting before you
adjust the setting again with the remote control.
Auto Cut Off
Your thermostat will automatically cutoff in Heat mode if the room temperature
rises above 95°F (35°C). It will cutoff in Cool mode if the room temperature
drops below 45°F (7°C).
Note that if your system has malfunctioned and no longer responds to ther-
mostat controls, the Auto Cut-Off will have no effect.
