Quick Start
Understanding Touch ‘N’ Go feature
The unique Touch ‘N’ Go feature on your thermostat is a revolutionary
tool that lets you use a simpler programming option – literally, touch and
go – to help you get the maximum comfort control from the entire comfort system.
With the touch of one Touch ‘N’ Go button – home, away or sleep – you
can tell your thermostat where you’ll be. To keep the home at that comfort level indefinitely, you add one more button – hold/run – and you’re
set. It’s the ideal choice for somebody whose schedule varies from day
to day or doesn’t fit into the two or four predictable time periods allowed
by the thermostat.
At the same time, these three comfort options – home, away and sleep –
are connected to the thermostat’s full-level programming power so that
you get the home comfort you desire exactly when you want it.
The three Touch ‘N’ Go buttons are preset at the factory for typical heating and cooling temperature settings and assigned to specific time periods. You can change these temperature settings and the hours you want
to use them easily. Learn how to do that and discover how useful this
device is as you read through this manual.
12
Programming the Thermostat
Programming the Touch ‘N’ Go feature
The Touch ‘N’ Go feature on your thermostat involves the home, away
and sleep buttons immediately under the display. They are used for
two programming options. One is more sophisticated than the other.
The simpler programming option requires you to either accept the
preset temperature settings for when you are home, away or asleep,
or to set your own Touch ‘N’ Go heating and cooling temperature
settings. Either way, your home, away and sleep settings are
automatically linked to one of four time periods that are also preset
(and changeable) on the thermostat.
You can override those preset time periods and their relationship to
your home, away and sleep buttons by pressing one of those three
buttons at any time. This will let you create a “temporary hold” at that
comfort level until the next programming period.
You can also hold the thermostat at your home, away or sleep
temperatures by pressing one of those three buttons and then
pressing the hold button.
This approach is popular with people who don’t follow the same
routine every day. And while you need to remember to push one
of those three buttons when you leave, come home, or go to bed,
13
Programming the Thermostat
doing that is easier for some than manually re-setting the temperature
several times a day.
The more sophisticated programming option works well with people who
tend to follow a more predictable routine and who also want to get the
most from this thermostat’s potential. For both programming options, you
must set-up your Touch ‘N’ Go heating and cooling temperatures in order
to use the thermostat’s expanded programming options.
Here are the temperature settings that are pre-programmed for your
home, away and sleep periods.

Programming the Thermostat
Changing the temperature time periods
After you have set your three Touch ‘N’ Go buttons with temperature
settings for when you’re away, home and asleep, you can program the
time of day you want to use for those temperature settings.
The thermostat has four time ranges called periods. They are identified
on the display as P1, P2, P3 and P4.
With four time period options, you have a great deal of schedule and
temperature flexibility. For example, in a household where nobody is
home during the day, the users might use P1 for the morning before
they leave for work, P2 for the hours they are at work, P3 for the period
when they are home in the evening, and P4 when they are sleeping.
In situations where somebody is home most of the day, P1, P2 and
P3 can all be assigned the same “home” temperatures, while P4 is
reserved for the sleeping hours. (To learn how to reduce the number
of time periods from four to two, see page 23.)
20

The thermostat has preset periods (see below), but you can change
these to fit your lifestyle.

Programming the Thermostat
Assigning time periods to temperatures
To get the most from your thermostat’s programming features, you will
want to take the remaining steps that will link your four schedule time
periods (P1, P2, P3 and P4) to the heating and cooling temperatures
you set with the Touch ‘N’ Go buttons – home, away and sleep.
Taking these final steps will be easier if you complete the grid below
before programming the thermostat. It will help you decide how you
want to assign the comfort temperatures you’ve selected for home,
away and sleep to the time periods you’ve established. The completed
grid will help you keep track of your information as you work with
the thermostat.
Here’s an example of how this would look using the factory-set
periods and Touch ‘N’ Go options.

Operating the Thermostat
Using Touch ‘N’ Go buttons
Once you have set the temperatures and time periods that correspond
with your three Touch ‘N’ Go comfort buttons (see Programming the
Touch ‘N’ Go feature, page 14, and Assigning time periods to
temperatures, page 27), you won’t need to use your Touch ‘N’ Go
buttons unless you want to make a temporary change. For example, if
you go to bed earlier than usual, pressing the sleep button will lower
the temperature sooner than scheduled. If you go to bed later than
usual, pressing the home button will keep the home warmer past your
usual bedtime but you’ll need to press sleep before you go to bed.
To make a temporary change
1. Open the door.
2. Press the home, away or sleep button that you want. You will see
the words temporary hold on the display and the triangle icon ( )
over the button you’ve selected. The system will change
to the temperature setting programmed for that lifestyle
period. It will maintain that temperature setting until the
start of the next programmed cycle.

3. To return to the originally programmed lifestyle period, press the
appropriate home, away or sleep button. The system will return to
that time period and the words temporary hold will disappear.
4. Close the door.
To hold it at home, away or sleep
There might be situations when you want to override the programming
and hold the home’s temperature at one of the three home, away or
sleep comfort levels. This is useful when you’re going on vacation or
traveling, or when you’re home unexpectedly. Here’s how to prevent
the thermostat from changing temperatures when it reaches the next
programming time period.
1. Open the door.
2. Press the desired button under the display – home,
away or sleep.
3. Press the hold/run button on the left side. You will see
the word hold on the display.

Using the thermostat to turn the heating and cooling system off
Here’s how to use the thermostat to turn the heating and cooling
system off.
1. Open the door.
2. Press the mode button on the top left repeatedly until
the display shows off in the upper left.
3. Close the door.
32
Operating the Thermostat
Using the fan
The fan function helps distribute warmth or cooling throughout your
home for a more even temperature in all spaces. The thermostat is
automatically set so that the fan runs only during your heating and
cooling cycles (auto mode). However, you can adjust the settings so
that the fan runs continuously, even between cycles or when the
system is turned off.
1. Open the door.
2. Press the fan button on the left side. You will see fan on
in the lower left corner of the display.
3. To return the fan to auto mode, press the fan button
again. You will see fan auto on the display.
4. Close the door.
33
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. Open the door.
2. Press the mode button three times. You will see
Em heat in the upper left of the display.
3. Close the door.
34
Operating the Thermostat
Changing the batteries
Your thermostat is probably powered by the HVAC equipment, but
if it isn't, it's battery powered. You can tell if it’s battery powered by
checking in Advanced Programming Options. (See page 38.) If there’s
no lighting until you touch a button, it’s battery powered. When the
thermostat uses electricity, the batteries (if installed) take over if the
electricity goes out. This allows you to monitor the indoor temperature
when there’s no electricity.
When powered by batteries, your thermostat’s two AA batteries should
last about one year. When your batteries have lost about one-third of
their power, a battery icon shows up on the display in the upper right
corner. Two-thirds of it will be black. As the batteries get weaker, the
icon goes down to one bar and then none. When the battery icon is
less than full, you will first see the loss of backlight function. When
the batteries are completely dead, you won’t be able to use the
thermostat.
35
Operating the Thermostat
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.
1. Locate the latch at the top of the thermostat. It’s at
the center of the top rim.
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.
36
Operating the Thermostat
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 two
slots on the bottom edge of the back of the thermostat with the
two lips on the wall bracket. You will feel the slots fit over the lips.
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.

Turning off the continuous backlighting
If your thermostat is not powered by the equipment and is instead battery
powered, the display will light 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, there is always a low level
amount of backlighting until you press any button, which increases the
lighting temporarily. Here’s how to turn off the constant low level backlight
when your thermostat is powered by electricity.
1. Open the door.
2. Press and hold the home and sleep buttons under the

Advanced Programming Options
Changing from programmable to nonprogrammable
It is possible to convert your thermostat’s operation from programmable
to nonprogrammable. This eliminates its advanced features. When
switching to the nonprogrammable format, you lose the programming,
hold, days of the week on the display, and Smart Recovery features.
Switching to nonprogrammable also means you’ll give up some of
the thermostat’s energy saving features. The time of day will still
show on the display and you will be able to increase or decrease the
temperature settings manually. Here’s how to switch to nonprogrammable.
1. Open the door.
2. Press and hold the home and sleep buttons under the
display simultaneously for about three seconds.
3. Press the up button at the top right of the display.
You will see U4 and P (for programmable). (If you
don’t, continue to press the up button, cycling
through the options until you get to U4 and P.)

Changing the number of programming periods
Your thermostat is preset with four time periods (P1, P2, P3, P4). You
can change this to two. Here’s how to change the number of periods
in the day.
1. Open the door.
2. Press and hold the home and sleep buttons under the
display simultaneously for about three seconds.
3. Press the up button at the top right of the display
repeatedly. You will see U5 and 4. (If you don’t,
continue to press the up button, cycling through
the options until you get to U5 and 4.)
4. Press the mode button on the left to change it from

5. Press the done button on the right.
6. Close the door.
46
Special Features
The thermostat displays one of five modes: heat, cool, Em heat
(heat pump version only), heat cool, and off. When the mode selection
is for both heating and cooling, 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
programmed. It does this automatically.
Smart Recovery
The Smart Recovery feature transitions your home from one temperature
period (P1, P2, P3, P4) to the next so that the your home’s temperature
matches the temperature setting at the start of each time period. This
means, for example, that if your sleep period temperature setting is
lower than the period that precedes it, the thermostat will start cooling
down the home before the beginning of the scheduled sleep period.
It does this at an energy-efficient rate. This not only helps make your
home as comfortable as possible, it also makes your thermostat more
cost effective. Call your dealer to adjust Smart Recovery settings.
47
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 you wait until the icon is just a silhouette with no black bars, the
thermostat won't have the power to function correctly. Replace the
battery to restore thermostat functions.
“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. When emergency heat has been turned on,
Em heat is displayed when you press the mode button. 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.
48
What if . . .
There is a power outage
If you lose electricity and have batteries installed, the thermostat will
continue to display the status 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.
In addition, you won’t have to reprogram the thermostat because your
settings are retained even if the battery dies. The display will continue
to show the time for 8 hours while there is no electricity.
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 This means the memory has failed and the thermostat will return
to the factory settings. Call your heating and cooling dealer.

Auxiliary heat (heat pump systems only) . . . . . . . . . . . . . . . .page 34
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 heat
on. You have no control over the auxiliary heat function.
Backlighting . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .page 40
