Changing the humidity level
Your thermostat offers three humidity* options: normal, auto and off. It is set at the
factory for “normal humidify,” which is a fixed setting based on how much
humidity you want in the home. This humidity level remains constant, regardless of
the outdoor temperature. You can manually adjust the humidity level according to
your own preferences.
The second option, “auto humidify,” uses an outdoor temperature sensor (when
installed) to automatically adjust the inside humidity level according to the outside
temperature when the thermostat is set for auto humidify.
You can also turn off the humidify/dehumidify feature.
Using normal humidify
Here’s how to change the fixed (constant) humidity setting.
1. Open the door. You will seehumidifyat the bottom of
the screen when the operating mode isheatordehumid-

factory --set at 26% for humidify and 60% for dehumidify.
It there’s too much condensation on the windows, try a
lower number. If the air is too dry, try a higher number. If
your home is newer and has quality windows that create a
“tight” home, try a higher setting. If your home is older,
you might need a lower setting. You can set the humidity
between 10% and 46%; the dehumidify range is from
46% to 66%.
4. Close the door.
Using auto humidify
The auto humidify feature automatically adjusts the amount of humidity according
to the outside temperature. It can be manually adjusted when there is too much
condensation accumulating on windows or the air seems too dry. Here’s how to
switch to auto humidify and make adjustments.
1. Open the door. Press thebutton underhumidify.Yo u

fyset atnumber (1 through 9). If there is too much con-
densation on the windows, select a number lower than 5.
If there seems to be a lot of static electricity, which often
means the air is too dry, select a number higher than 5. If
your home is newer and has quality windows that create a
“tight” home, try a higher setting. If your home is older,
you might need a lower setting.
4. Close the door.

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 isauxiliary 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 themodebutton repeatedly until the arrow
under the button moves toEm heaton the
screen.
3. Close the door.

displayed on the screen, pressing and holding thedonebutton for about three
seconds clears all reminders on the screen. This might not be the best option when
you have multiple reminders but have done only one of the tasks. This option lets
you reset the reminders individually.

cool setpointssimultaneously (the two bottom buttons
