*Room temp. controlled: = Controlled room temperature
•When body thermostat controlled:
Controlled room temperature = Indoor unit intake temp. (TA) – Intake temperature shift (*1)
•Remote control thermostat controlled:
Controlled room temperature = Remote controller temp.
*1 Intake temperature shift: This is the shift value considered the temperature difference between the upper area
and lower area of the room in heating mode.
It is the value of the code “06” in the indoor unit’s EEPROM setting.
