6. Automatic Heating / Cooling Control

( )* : FRESH AIR INTAKE MODE (Type E2)
This function is only valid as long as one indoor unit is installed within one refrigerant system or all indoor
units are controlled within a group control.
When operating in a group control, the sub-indoor units become the same operation mode of the main unit.
As for the indoor units in a group control, install them in the same air conditioning circumstances.
Use the temperature sensor which is built-in sensor of the indoor unit.
The operating mode is selected according to the set temperature and room temperature when the
operation is started.
Room temperature >
Room temperature < set temperature in remote controller – 1˚C (– 5˚C)* → Heating mode
The set temperature is corrected according to the operating mode. The correction temperature is +2
degrees in cooling mode and -2 degrees in heating mode at the time of factory shipment.
The correction value is different depending on the model. See "14. Parameter" for details.
Corrected cooling temperature – control temperature for cooling
Corrected heating temperature – control temperature for heating
When setting temperature in remote controller is 20˚C in the cooling mode (at shipment) :
Control temp. for cooling
Set temp. in remote controller
Control temp. for heating
Condition for mode change
Heating → Cooling: Room temperature > Control temperature for cooling + 0.5 degree
Cooling → Heating: Room temperature < Control temperature for heating -1.0 degree
When setting temperature in remote controller is 20˚C in the cooling mode :
Temp. for switching to cooling +2.5deg (+5.5deg)*
Control temp. for cooling
Cooling thermostat OFF temp.
