condition using the wired remote controller. Follow
the instructions in the supplied Owner’s Manual when
operating the unit.
If you use a wireless remote controller for operations,
follow the instructions in the Installation Manual
supplied with the indoor unit.

the thermostat automatically turns the unit off due to
the indoor temperature, follow the procedure below.
The forcible test run will automatically stop after
