What the blinking mode icon means

Basic operations

Auto (dual set point) and Setback modes:
When the operation mode is set to the Auto (dual set point) mode or the Setback 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.
Differences between the two modes · Auto (dual set point) mode The set temperatures that are specified for the Cool/Drying 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.

· Setback mode Room temperature is controlled to stay within the set temperature range that is specified for the Setback mode. By leaving sufficient temperature differential between the set temperature for cooling (upper limit) and heating (lower limit), it is possible to keep the room temperature within the specified range without overworking the air conditioners. This setting will be especially effective during periods of non- occupancy.
