EXPLANATION OF HEATING OPERATION (except RXQ series)
• For general heating operation, it may take longer to reach the set
temperature than in cooling operation.
We recommend starting the operation which was used before
using timer operation.
• The following operation is performed in order to prevent the heat-
ing capacity from dropping or cold air from blowing.
Defrost operation
• In heating operation, freezing of the outdoor unit heat
exchanger increases. Heating capability decreases and the
system goes into defrost operation.
• The indoor unit fan stops and the remote control displays
“
”.
• After maximum 10 minutes of defrost operation, the system
returns to heating operation again.
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 auto-
matically stopped. The display of the remote control shows
“
”.
Note
•
The heating capacity drops as the outside temperature falls. If this
happens, use another heating device together with the unit.
(When using the appliances which produce open fire together,
ventilate a room constantly.)
Do not place appliances which produce open fire in places
exposed to the air flow from the unit or under the unit.
• It takes some time for the room to warm up from the time the unit
is started since the unit uses a hot-air circulatory system to warm
the entire room.
• If the hot air rises to the ceiling, leaving the area above the floor
cold, we recommend using the circulator (the indoor fan for circu-
lating air). Contact your dealer for details.
1-6-2 Program Dry Operation
• The function of this operation is to decrease the humidity in
your room with a minimum temperature decrease.
• The micro computer automatically determines temperature
and fan speed.
• The system does not go into operation if the room temper-
ature is low.
• The microcomputer automatically controls the temperature
and fan speed, so these cannot be set using the remote
control.
• This function is not available if the room temperature is
20°C or lower.
