Auto change over operation

Auto changer over operation is the function to maintain the optimal indoor temperature without any
manual control through automatic change over of operating mode (Cool, heat) of the air conditioner.
For example, when number of people increase to suddenly raise the indoor temperature during heating
operation, AC Smart automatically changes from heat to cool mode to operate the indoor unit of the air
conditioner to maintain the indoor temperature at a certain range.
The user enters the temperature difference from the reference temperature. AC Smart operates based
on the input value as follows.
• When the indoor temperature exceeds the temperature difference from the reference temperature, it
runs the cool operation to lower the indoor temperature.
• When the indoor temperature drops below the temperature difference from the reference
temperature, it runs the heat operation to raise the indoor temperature
But when the temperature deviates from the indoor temperature range by the control/monitoring or
schedule etc., the temperature is not controlled by this function.

This can't be controlled by the Auto Changeover
function because it is caused by other functions
such as Basic Control or Schedule. Thus, it doesn't
need to be operated in the Cool mode.
