4. Operating AC Smart
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
To execute the auto change over operation function, you must set the reference set temperature,
temperature difference and reference temperature.
• Reference set temperature can be set in the range of 18°C ~ 30°C (Default: 24°C).
• Temperature difference can be set in the range of 1°C~7°C (Default: 4°C).
Temperature reference can be set by one of the 3 following methods.
• All unit average: This is the method of operating the auto change over operation function based on
the average temperature detected for the indoor units within the group.
• Operating unit average: This is the method of operating the auto change over function based on the
average temperature of the operating indoor units within the group.
• Fixed: This is the method of operating the auto change over operation function based on the
temperature detected from the first registered indoor unit within the group.
When the set value or temperature reference changes during the auto change over operation
function, the changed setting is reflected when operating mode (Cool, heat) changes.
This chapter will describe the method and order of operating the function of AC Smart by using the
Auto control menu.
