To stop the wrong wiring automatic detection, push BS3. If
this function was not aborted by pushing BS3, the unit will
stop its operation after 30-90 minutes. The operation time
will depend on the number of connected indoor units.
If wrong wiring is detected after operation, the outdoor unit
and corresponding indoor unit display the error code "UF"
while the other indoor units display the error code "U9".
“oH” is displayed if no wrong wiring is detected. (Press the

This function can be used when the outdoor temperature
is between 23°F and 68°F (-5°C and 20°C) and the indoor
temperature is between 68°F and 81°F (20°C and 27°C).
If the indoor temperature is outside the above range, either
cooling or heating is automatically started to bring the indoor
temperature to the suitable temperature.
If the outdoor temperature is outside the above range and
the indoor temperature is outside the above range even
after cooling or heating, the error codes “E-2” and “E-3” are
displayed, and the function cannot be used.
