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 modebut- "_001
ton on the left until the screen says hoar. o
2. Press the up or down button located on the right side of
the display until you reach the desired temperature, o_:]
3. To change the cooling temperature, press the mode but- o
ton 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.
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 °l I°]
again. You will see fan auto on the display, e
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. OL_oO ]2. To turn off emergency heat, press the mode button again o
to select heat, cool or auto.
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, abattery 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. Ix_cate the latch at the top of the thermostat. It's at the f/_
center of the top rim.
2.Pressitdown.Thiswilldisconnectthethermostatfromthe

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.
11. Close the door.
Using the thermostat to turn the heating and cooling system off
To use the thermostat to turn the heating and cooling system _oO]
off, press the mode button on the left repeatedly until the •
display shows off in the upper left. O
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.
Advancedoptions display codes chart
You can customize a few features of your thermostat. This chart shows which
features you can change and the codes associated with them. The codes will be
shown on the display when you follow the instructions.
Fahrenheit to Celsius U1 F or C
backlighting U2 On or Of
keypad lockout U3 Of, On, padlock
ChangingfromFahrenheit 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 U7 and the letter Fin the center.
2. Press the up or down button on the right to change it
from F(Fahrenheit) to C (Celsius).
3. Press the fan button on the left to exit this screen.
Turning on the continuous bacMighting
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
o' :J
powered by electricity.
1. Press and hold the mode button for about three seconds.
The display will show U7 and the letter Fin 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.
Keypadlockout
Thekeypadlockoutfeatureletsyou"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 Fin
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 indic-
ates the keypad is locked.
4. Press the fan button on the left to exit this screen.
Unlockingthe keypad
Here's how to temporarily unlock the keypad.
1. Press and hold the up and down buttons onthe right o_:]
simultaneously for about five seconds, o
2. The padlock icon will disappear. This means the keypad is unlocked and
can be used. The keypad will revert back to the locked state after you've
stopped pushing buttons for two minutes.
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 hap-
pens 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.
Thereis 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.
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.
Auto changeover .......................................... page 14
This feature automatically switches your system from heating to cooling - or from
cooling to heating - whenever necessary.
Auxiliary heat (heat pump systems only) .................... page 10
Most heat pump systems can't heat a home sufficiently when it gets very cold
outside so they use a supplemental heating source called auxiliary heat. The system
knows when to use this help and does so automatically. If it's using auxiliary heat,
the display will show aux boat on. You have no control over the auxiliary heat
function.
BacMighting .............................................. page 17
Backlighting illuminates your display when you push a button.
Emergency heat (heat pump systems only) .................. page 10
You can manually set the thermostat to use emergency heat but it is the most
expensive option. If it's using emergency heat, the display will show Em boat.
Mode .................................................... page 14
This term refers to the type of operation your system is performing. The options are
heat, cool, emergency heat, auto, and off.
