Use this feature in climates where both air conditioning and heating are used on the

same day. When the system mode is in Auto, the thermostat automatically selects

heating or cooling depending on the indoor temperature.

While in the Auto mode, if a schedule override takes place (temporarily or perma-

nently) the thermostat will automatically adjust the cooling and heating settings to

maintain a 3-degree separation between the cool and heat settings.

For example, if the heat temperature is raised to where it gets within 3-dgrees of the

cool setting, the display will show an up arrow next to "cool" to show the thermostat

is raising the cool setting up to maintain a 3-dgreee separation.

The display will also show both "Auto" and either "Heat" or "Cool" for which tempera-

ture setting you are currently adjusting. Press the system button to select between

the heat and cool to view/adjust either mode.
