- Refer to the circuit diagram for the connection locations for each
thermistor.
- If there is an abnormality in the room temperature thermistor, the
temperature will be fixed at 25°C regardless of the remote control
unit display.
NOTE:
- Any abnormalities detected by the temperature thermistors are
ignored during emergency operation, so that long-term operation
in this mode should be avoided.
- After emergency mode operation has been completed and normal
operation is to be resumed, turn the power supplies for the indoor
and outdoor units off and return the DIP switch to the NORMAL
position.
- Self-diagnosis LEDS 4 to 6 will flash during emergency operation.
