Auto (Dual Set Point) Mode - Mitsubishi Electric AT-50B Instruction Book

Auto (dual set point) mode:

When the operation mode is set to the Auto (dual set point) mode, two set temperatures
(one each for cooling and heating) can be set. Depending on the room temperature, indoor
unit will automatically operate in either the cooling or heating mode and keep the room
temperature within the preset range.
The set temperatures that are specified for the Cool/Dry mode and the Heat mode will be
used to automatically control the room temperature to stay within the set temperatures.
This mode is especially effective during the in-between seasons, when the temperature
difference between the highest and the lowest is large and both heating and cooling modes
are used within the same day.
