Explanation of heating operation
It may take longer to reach the set temperature for
general heating operation than for cooling operation.
The following operation is performed in order to
prevent the heating capacity from dropping or cold
air from blowing.
Defrost operation
• In heating operation, freezing of the outdoor
unit's air cooled coil increases over time,
restricting the energy transfer to the outdoor
unit's coil. Heating capability decreases and the
system needs to go into defrost operation to be
able to deliver enough heat to the indoor units:
• When an outdoor unit is operating defrost,
the indoor unit will stop fan operation, the
refrigerant cycle will reverse and energy from
inside the building will be used to defrost the
outdoor unit coil.
• The indoor unit will indicate defrost operation on
the displays "

Hot start
In order to prevent cold air from blowing out of an
indoor unit at the start of heating operation, the
indoor fan is automatically stopped. The display of
the user interface shows "
It may take some time before the fan starts. This is
not a malfunction.
INFORMATION
• The heating capacity drops when the
outside temperature falls. If this happens,
use another heating device together with
the unit. (When using together with
appliances that produce open fire,
ventilate the room constantly).
Do not place appliances that produce
open fire in places exposed to the air flow
from the unit or under the unit.
• It takes some time to heat up the room
from the time the unit is started since the
unit uses a hot-air circulating system to
heat the entire room.
• If the hot air rises to the ceiling, leaving
the area above the floor cold, we
recommend that you use the circulator
(the indoor fan for circulating air). Contact
your dealer for details.

6.2 Program dry operation

• The function of this program is to decrease the
humidity in your room with minimal temperature
decrease (minimal room cooling).
• The microcomputer automatically determines
temperature and fan speed
(cannot be set by the user interface).
• The system does not go into operation if the
room temperature is low (<20°C).
