Emergency operation
Emergency operation is available when the remote
controller malfunctions, has been lost, or otherwise
cannot be used.
To operate the system, press the OPERATION button,
which is also used as the receiver, below the unit display.
Each time this button is pressed, the OPERATION lamp
changes color to indicate the type of operation. Select the
desired type of operation.
COOL
(GREEN)
The set temperature is 4°F(2°C) below the detected room
temperature in the case of cooling operation, and 4°F(2°C)
above the room temperature in the case of heating
operation. The flap and fan speed settings are AUTO.
Auto Initial Operation Mode Selection
Selecting the operation mode
When AUTO mode is selected, the microprocessor calculates
the difference between the set temperature and the room
temperature, and automatically switches to Cooling or Heating
mode.
Room temp. Set temp.
Room temp. Set temp.
Once the mode is selected based on this function, the unit will
