7. Discharge Air Temperature Control
Discharge air temperature is controlled using the indoor unit discharge air temperature sensor. The discharge
air temperature is set in the EEPROM on the PCB. The setting is different depending on the model. Refer to
“15. Parameter” for details.

① Temperature less than “Discharge air temperature setting – 2˚C” is continuously detected for 20
minutes in cooling mode
② Temperature more than “Discharge air temperature setting + 2˚C” is continuously detected for 20
minutes in heating mode
③ Temperature less than “Discharge air temperature setting – 3.5˚C” is continuously detected for 7
minutes in cooling mode
④ Temperature more than “Discharge air temperature setting + 3.5˚C” is continuously detected for 7
minutes in heating mode
There is no priority order between the room temperature control and discharge air temperature control.
Relation between thermostat ON/OFF and room temperature control/discharge air temperature control
Thermostat turns OFF: Either room temperature control or discharge air temperature control satisfi es
thermostat OFF condition.
Thermostat turns ON: Both of room temperature control and discharge air temperature control satisfy
thermostat ON condition.
8. RAP Valve Kit Control
The RAP valve kit is sometimes used in the 2-Way system.
The RAP valve kit prevents refrigerant from collecting in the indoor heat exchanger when the indoor unit is
stopped. The following table shows the RAP valve kit operation.
