Operating the Thermostat
Setting the temperatures for heating and cooling
Your thermostat is installed with the heating set at 68° F and the
cooling set at 72° F. You can use these or change them so your home
is as warm or as cool as you would like it to be. These steps will hold
the temperature where you set it.
1. To change the heating temperature, press the
mode
button on the left until the screen says heat.
2. Press the
up or down button located on the right side
of the display until you reach the desired temperature.
3. To change the cooling temperature, press the
mode
button on the left until the screen says cool.
4. Press the
up or down button located on the right side
of the display until you reach the desired temperature.
9
Operating the Thermostat
Using the fan
When the fan is on, it helps distribute air throughout your home for a
more even temperature in all spaces. You can set the thermostat so
that the fan runs only during your heating and cooling cycles (auto
mode) or to run continuously.
The thermostat is set at the factory to run automatically as needed.
Here’s how to change the setting so it runs continuously.
1. Press the
fan button on the left. The display message
will change from
auto fan to fan on.
2. To return the fan to auto mode, press the
fan button
again. You will see
fan auto on the display.
10
Operating the Thermostat
Using emergency heat (heat pump systems only)
Emergency heat is useful when the automatic auxiliary heat system
can’t keep up with demand. (Systems with heat pumps use “auxiliary
heat” when it’s too cold outside for the heat pump to heat the house
without help. The display indicator for this is
aux heat on.)
If the heat pump compressor that works with auxiliary heat fails, or if
the heat pump isn’t working at all, you can turn on the emergency
heat for that extra help. (You’ll know there’s a problem if the house
can’t seem to get warm when it’s very cold outside.) You want to avoid
using emergency heat, though, because it’s the most expensive
option. And, of course, if you suspect a problem with your heat pump,
call your heating and cooling dealer immediately.
Here’s how to set your thermostat to use emergency heat.
1. Press the mode button repeatedly until you see Em
heat
in the upper left of the display.
2. To turn off emergency heat, press the
mode button
again to select
heat, cool or auto.
11
Operating the Thermostat
Installing or replacing the batteries
You can install batteries in your thermostat so that if the power goes
out, the display will still show the indoor temperature.
In some situations, batteries are also the power source. Then, two AA
batteries should last about one year. When the batteries have lost
about one-third of their power, a battery icon appears on the display.
Two-thirds of it will be black. As the batteries get weaker, the icon
goes down to one black bar and then none. When the icon is empty,
you will begin to lose thermostat functions when it is battery powered.
When the batteries are completely dead, you won’t be able to use the
thermostat.
When using batteries for power, we recommend that you replace the
batteries at the one bar level with two AA alkaline batteries. They’re in
the back of the thermostat, so you’ll have to remove it from the wall.
Here’s how to both install and replace batteries.
1. Locate the
latch at the top of the thermostat.
It’s at the center of the top rim.
12
Operating the Thermostat
2. Press it down. This will disconnect the thermostat
from the top of the wall plate.
3. Remove the thermostat from the
wall bracket
completely by bringing it slightly toward you and
lifting it up and off the
lip on the lower edge of the
wall bracket.
4. Set the thermostat face down on a flat surface. You
will see the batteries in the lower right corner.
5. Remove and discard the old batteries.
6. Install new batteries by matching the “plus” and
“minus” ends of the batteries with the “plus” and
“minus” indicators you’ll see outside the two white
battery shapes in the space where the batteries sit.
7. Snap the batteries into place.
8. Put the thermostat back on the
wall bracket by lining up the slot
on the bottom edge of the back of the thermostat with the lip on
the
wall bracket. You will feel the slot fit over the lip.
13
Operating the Thermostat
9. With the bottom of the thermostat attached to
the bottom of the
wall bracket, bring the thermostat
back to the wall. Line up the
latch at the top of
the thermostat with the corresponding
lip on the
wall bracket.
10. Lightly push the thermostat toward the wall. When the
latch and lip
are lined up properly, you will hear the thermostat snap into place.
14
Operating the Thermostat
Using the thermostat to turn the heating and cooling system off
To use the thermostat to turn the heating and cooling
system off, press the
mode button on the left repeatedly
until the display shows
off in the upper left.
Auto changeover
The thermostat uses one of five modes: heat, cool, Em heat (heat
pump version only), auto, and off. When the mode selection is auto,
the thermostat is in auto changeover mode. This allows the system
to switch from heating to cooling – or from cooling to heating – to
maintain the temperatures you’ve set. It does this automatically.

Changing from Fahrenheit to Celsius
Your thermostat is preset to display the temperature in degrees
Fahrenheit. You can change this to Celsius.
1. Press and hold the
mode button for about three
seconds. The display will show
U1 and the letter F
in the center.
2. Press the

Advanced Options
Turning on the continuous backlighting
The thermostat display lights up for a few seconds after you press any
button. This is backlighting. It will go dark after a few seconds.
If the thermostat is powered by electricity, it is possible to have a
constant low level amount of backlighting until you press any button,
which increases the lighting temporarily. Here’s how to turn on the
constant backlight when your thermostat is powered by electricity.
1. Press and hold the
mode button for about three
seconds. The display will show
U1 and the letter F
in the center.
2. Press the
mode button twice. The display will show U2
and Off.
3. Press the
up or down button on the right to change it
from
Off to On.
4. Press the
fan button on the left to exit this screen.
18
Advanced Options
Keypad lockout
The keypad lockout feature lets you “lock” the thermostat so nobody
can change the temperature – or make any other changes – by pressing
buttons. Keypad lockout is not activated when the thermostat is
installed. Here’s how to activate it.
1. Press and hold the
mode button for about three
seconds. The display will show
U1 and the letter F
in the center.
2. Press the
mode button until the display shows U3 and Of.
3. Press the up or down button on the right to change
it from
Of to On. You will also see a padlock, which
indicates the keypad is locked.
4. Press the
fan button on the left to exit this screen.
19
Advanced Options
Unlocking the keypad
Here’s how to temporarily unlock the keypad.
1. Press and hold the
up and down buttons on the right
simultaneously for about five seconds.
2. The
padlock icon will disappear. This means the keypad is unlocked
and can be used. They keypad will revert back to the locked state
after you’ve stopped pushing buttons for two minutes.
20
What if . . .
The battery icon is displayed
The battery icon appears on the display only when the battery starts
to lose power. Replace it when one-third of the icon is black. If your
thermostat is battery powered and you wait until the icon is just a
silhouette with no black bars, you will slowly lose thermostat functions
until it doesn’t work at all.
“Aux heat on” is displayed (heat pump systems only)
Aux heat on is auxiliary heat. It applies only to the heat pump version.
If it is on, you will see
aux heat on. When it is displayed, it means the
system has determined that it’s too cold outside for your heat pump
to heat the house without help, so it’s getting help from the electric
heaters. This happens automatically.
“Em heat” is displayed (heat pump systems only)
Em heat is the display term for emergency heat and applies only
to the heat pump version. You have to turn on emergency heat
manually – it doesn’t happen automatically – so if you see
Em
heat
on the display, it means somebody has turned it on.
21
What if . . .
There is a power outage
If you lose electricity and have batteries installed, the thermostat will
continue to display the indoor temperature because it has a battery
backup power source. This means that even though your heating and
cooling system doesn’t work, you will still be able to monitor your
home’s temperature. Your settings will also be saved.
You get a system error message
Here are the possible system error messages and what they mean:
-- The room air sensor reports that the room air temperature is
above 150° or below -50°.
E4 The memory has failed and the thermostat will return to the
default factory settings. Call your heating and cooling dealer.
