OFF or the switch's fuse is
burnt.
Set the remote
controller's temperature
setting to:
(1)When
cooling:Minimum
(2)When
heating:Maximum

receiving section
blinking?
Measure the suction
/disharge temperature.
Units equipped with liquid
crystal remote controllers only
Units equipped with wireless
remote controllers only
Did you allow 3 minutes to
elapse after turning ON?
Is there something causing the
indoor load to be large, such as
an open window or door?
(Temperature differential
=suction temperature - discharge temperature)
Units equipped with liquid
crystal remote controllers only
Operation is
normal.
Temperature
differential is 8~18˚C
The units runs but
doesn't heat the
room.
Measure the suction
/discharge temperature.
Is there something causing the
indoor heat load to be large, such
as an open window or door?
(Temperature differential
=discharge temperature - suction temperature)
Operation is
normal.
Temperature
differential is 14~30˚C
