Setting the temperatures for heating and cooling
Your thermostat is installed with pre–set heating and cooling temperature settings. You can use these or change them so your home is as warm or as cool as you’d like it to be. These steps will hold the temperature where you set it. For the temperature to change automatically according to your lifestyle needs – whether you’re home, away or asleep – you’ll need to follow the Touch ‘N’ Go instructions on pages 13 –19.

1. 1. Open the door.
   2. Press the up or down button located on the right side of the display. You will see the preset temperature settings for heating and cooling. The word heat will flash.
   3. Press the up or down button to change the heat setting. Stop on the correct setting.
   4. Press the hold/run button.
   5. Press the mode button located on the left side of the dis-play once. You will see the preset temperature setting for cooling appear on the right side of the display.
   6. Press the up or down button. The word cool will flash.
   7. Continue pressing the up or down button to change the cool setting. Stop at the desired cooling setting.
   8. Press the hold/run button located on the left side of the display. This holds the thermostat at that setting.
   9. Press the done button.
   10. Close the door.

 

Changing the temperature
There are times when you want to change the temperature. Here’s how.

1. Open the door.
2. Press the up or down buttons on the right side until you reach the desired temperature setting. This creates a “tem-porary hold” until the next pre–set time period. You will see temporary hold on the display. (To switch from the cooling temperature to the heating temperature – or vice versa – press the mode button on the left until the word heat or cool is flashing.)
3. To maintain that temperature setting so it doesn’t change during the next pre–set time period, press the hold/run button on the left side. The display will show hold.The temperature will stay at the setting you selected until you release the hold.
4. To return the temperature to the pre–set level for that time period, press hold/run. This releases the hold and the tem-perature will return to its programmed level.
5. Close the door.

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.

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, 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.

Touch ‘N’ Go Option	Heat	Cool
Home	68	74
Away	60	85
Sleep	66	78

Use this blank grid to determine how warm or cool you want your home to be when you’re home, away or asleep. You’ll assign time periods to those temperatures later.

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 displayasP1,P2,P3andP4.
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 22.)
The thermostat has preset periods (see below), but you can change these to fit your lifestyle.

Period	Preset Hours
P1	6:00 AM to 8:00 AM
P2	8:00 AM to 5:00 PM
P3	5:00 PM to 10:00 PM
P4	10:00 PM to 6:00 AM

What time blocks work for you? Write them in here and refer to this as you make the changes on the thermostat.

Period	Your Hours
P1
P2
P3
P4

Here’s how to change the factory–set time periods.

1. Open the door.
2. Press the days button at the bottom of the thermostat. You will see all days, weekdays and weekends flashing on the display. You will be changing the time periods accord-ing to the days of the week. All days is used when the household’s weekday and weekend schedules are the same.
3. You must select one of these three time–frame options – all days, weekdays or weekends – by pressing the up or down button located to the right of the display. You may also make your selection by pressing the days button again. (Select all days if your weekday and weekend schedules are the same.)
4. When you have selected one of the three options (all days, weekdays, weekends), press the period button at the bottom of the thermostat. You will see P and a flashing 1 on the screen. This is period 1 (P1), which begins at 6:00 AM.
5. To change the hours in P1,press thestart time button at the bottom of the screen.
6. You will see the hours in 6:00 AM flashing on the screen. Press the up or down button and stop on the desired time.
7. To change the minutes, press the start time button on the bottom of the screen again. You will see the minutes in 6:00 AM flashing on the screen. Press the up or down button and stop on the desired time.
   The “stop time” for period 1 (P1) is also the “start time” for period 2 (P2). To change the stop time for P1 – which means you are also changing the start time for P2 – use the instructions in the next step to change the start time for period 2.
8. To change the start time for period 2 (P2), press the period button at the bottom of the screen twice. This displays the information for period 2, with P2 flashing on the display.
9. You will see the hours in 8:00 AM flashing on the screen. Press the up or down button and stop on the desired time.
10. To change the minutes, press the start time button on the bottom of the screen again. You will see the minutes in 8:00 AM flashing on the screen. Press the up or down button and stop on the desired time.
11. To change the start time for period 3 (P3), press the period button at the bottom of the screen three times. This displays the information for period 3, with P3 flashing on the display.
12. You will see the hours in 5:00 PM flashing on the screen. Press the up or down button and stop on the desired time.
13. To change the minutes, press the start time button on the bottom of the screen again. You will see the minutes in 5:00 PM flashing on the screen. Press the up or down button and stop on the desired time.
14. To change the start time for period 4 (P4), press the period button at the bottom of the screen repeatedly. This displays the information for period 4, with P4 flashing on the display.
15. You will see the hours in 10:00 PM flashing on the screen. Press the up or down button and stop on the desired time.
16. To change the minutes, press the start time button on the bottom of the screen again. You will see the minutes in 10:00 PM flashing on the screen. Press the up or down button and stop on the desired time.
17. If you did not select all days when you started this process, repeat all the steps for your remaining time–frame choice – weekdays or weekends.
18. To confirm that the thermostat has accepted your changes, cycle through the four time periods by pressing days, selecting your time frame – all days, weekdays, or weekends – and then pressing the period button to see the hours assigned for each start time. Each time you press period, you will advance to the next start time.
19. Close the door.

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.

Pre — set Period Start Time	Period Number	Pre — set Touch ‘N’ Go Option for Each Period
6:00 AM	1	Home
8:00 AM	2	Away
5:00 PM	3	Home
10:00 PM	4	Sleep

Complete this schedule according to daily routine and use it as you follow the instructions below.

Your Period Start Time	Period Number	Your Touch ‘N’ Go Option for Each Period
	1
	2
	3
	4

Here’s how to connect your four time periods with the three comfort ranges – home, away and sleep.

1. Open the door.
2. Press the days button at the bottom of the thermostat. You will see all days, weekdays and weekends flashing on the display.
3. Select one of these three options by pressing the up or down button located to the right of the display. You may also make your selection by pressing the days button again. Select all days if your weekday schedule is the same as your weekend schedule.
4. When you have selected one of the three options (all days, weekdays, weekends), press the period button at the bottom of the thermostat. P1 will flash on the display.
5. Press the Touch ‘N’ Go button – home, away or sleep –you want to use during period 1 (P1) from the row of but-tons just below the display. You will see the triangle icon
   (B) above the button selected. This tells the thermostat whether you are home, away, or asleep during P1. The thermostat will use the heating and cooling temperature settings you’ve selected for that Touch ‘N’ Go button. For example, if your heating temperature setting for home is 72 degrees, the thermostat will keep the heat at 72 during P1.
6. Press the period button twice. P2 will flash on the display.
7. Press home, away or sleep.
8. Press the period button twice. P3 will flash on the display.
9. Press home, away or sleep.
10. Press the period button twice. P4 will flash on the display.
11. Press home, away or sleep.
12. If you did not select all days when you started this process, then repeat all the steps for your remaining time–frame choice – weekdays or weekends.
13. To confirm that the thermostat has accepted your changes, cycle through the four time periods by pressing days, selecting your time frame – all days, weekdays,or weekends – and then pressing the period button to see the Touch ‘N’ Go option assigned for each start time. Each time you press peri-od, you will advance to the next start time.
14. Press done or close the door.

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 13, and Assigning time periods to temperatures, page 26), 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 set-ting until the start of the next programmed cycle.
3. To return to the originally programmed lifestyle period, press the appropri-ate home, away or sleep button. The system will return to that time peri-od 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.
4. To return to your original programming schedule, press the hold/run button. The word hold will disappear.
5. Close the door.

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.

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.

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.

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 37.) 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.

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 cen-ter 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 com-pletely 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 or recycle the old batteries.
6. Install new batteries by matching the “plus” and “minus” ends of the batter-ies 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 brack-et, 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.

3. 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.
4. Close the door.

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 (flashing) and P (for programmable). (If you don’t, continue to press the up button, cycling through the op-tions until you get to U4 (flashing) and P.)

5. Press the done button on the right.
6. Close the door.

SPECIAL FEATURES

Auto Changeover
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.

WHATIF…

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.

Thereisa poweroutage
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.

COMMON TERMS AND WHERE TO FIND THEM

Auto changeover
This feature automatically switches your system from heating to cooling – and from cooling to heating – whenever necessary when the thermostat is set in auto mode.

Auxiliary heat (heat pump systems only)  
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  
backlighting illuminates your display. When the thermostat is powered by electricity, the backlight is on constantly at a dim level that brightens when you push a button. With battery powered thermostats, the backlight is off until you press a button.

Emergency heat (heat pump systems only) 
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 heat when you press the mode button.

Hold  
This function holds the current set temperature.

Mode 
This term refers to the type of operation your system is performing. The options are heat, cool, emergency heat, heat cool, and off.

Override 
This happens when you temporarily disregard the thermostat’s programmed temperature settings and schedules by using the temporary hold or hold options.

Smart Recovery
This feature allows your system to shift from one temperature period to the next scheduled period at an energy–efficient rate.

Temporary hold 
This function lets you temporarily maintain your temperature settings. The system will return to the scheduled settings during the next time period.

Time period  
The thermostat features four time periods. These blocks of time are linked to temperatures you set according to how warm or cool you want the house during those time periods. The time periods are also linked to your Touch ‘N’ Got settings of home, away and sleep.

Touch ‘N’ Go
The three Touch ‘N’ Go buttons – home, away and sleep – let you change programmed time periods with the touch of a button. They are particularly useful for somebody who doesn’t want to take advantage of the thermostat’s full programming capability or somebody whose schedule varies from day to day.Copyright 2014 Carrier Corporation, 7310 W Morris St. Indianapolis, IN 46231
