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 but- ton 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 but- 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.

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. Heres 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 cant keep up with demand. (Systems with heat pumps use auxiliary heat when its 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 isnt working at all, you can turn on the emergency heat for that extra help. (Youll know theres a problem if the house cant seem to get warm when its very cold outside.) You want to avoid using emergency heat, though, because its the most expensive option. And, of course, if you suspect a problem with your heat pump, call your heating and cooling dealer immediately.

Heres 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 wont 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. Theyre in the back of the thermostat, so youll have to remove it from the wall.

Heres how to both install and replace batteries.

1. Locate the latch at the top of the thermostat. Its 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 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 batteries with the plus and minus indicat- ors youll 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 youve set. It does this automatically.

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 doesnt 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 its too cold outside for your heat pump to heat the house without help, so its 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 doesnt 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 doesnt work, you will still be able to monitor your homes 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.
