Sensor Temperature Display Function
(displayed regardless of whether unit is operating or stopped)
The procedure below displays the sensor temperatures from the remote controller, indoor unit, and outdoor unit on
the remote controller.
NOTE
The temperature display appears as “- - - -” for units that are not connected.
* If monitor mode is engaged while normal operation is in progress, only the parts of the LCD display shown in the
figure will change. Other parts continue to display the same information as during normal operation.

•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.
