keeping your programmed heating and cooling temperature at least 4
˚
F (2
˚
C) apart to
allow the Auto Season Changeover to occur when the appropriate temperature span has
been reached. However, if your heating and cooling programs set temperatures are
close, there is a built-in program to prevent the thermostat is in Temporary, a Designated
Day Override or Permanent Override, as these overrides are energy saving settings.
Auto Season Changeover will still function in Home Today mode, as this is a comfort
setting.

Heat Set Temp=68
˚
F, Cool Set Temp=78
˚
F
If the room temperature rises above 78
˚
F, then the thermostat will automatically change
to cool mode and turn on the air conditioner.
Likewise, the thermostat will automatically change to heart mode and turn on heat when
the room temperature falls below 68
˚
F.
