Auto changeover
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
permanently) 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-degrees 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-degree separation.
The display will also show both "Auto"
and either "Heat" or "Cool" for which
temperature setting you are currently
adjusting. Press the system button to select between the heat and cool to view/
adjust either mode.
CAUTION: To avoid possible compressor damage, do not use Auto
Changeover if the outside temperature drops below 50°F (10°C).
