NOTE
<Note on HEAT mode operation>
Since this air conditioner heats the room by taking heat from
outdoor air to indoors, the heating capacity becomes smaller in
lower outdoor temperatures. If the heating effect is insufficient, it
is recommended to use another heating appliance in
combination with the air conditioner.
The heat pump system heats the room by circulating hot air
around all parts of the room. After the start of heating operation,
it takes some time before the room gets warmer.
In heating operation, frost may occur on the outdoor unit and
lower the heating capacity. In that case, the system switches
into defrosting operation to take away the frost. During
defrosting operation, hot air does not flow out of indoor unit.
<Note on DRY mode operation>
This operation dehumidifies the indoor air when it is humid.
<Note on AUTO operation>
In AUTO operation, the system selects a temperature setting
and an appropriate mode (COOL or HEAT) based on the room
temperature at the start of the operation.
The system automatically reselects setting at a regular interval to
bring the room temperature to user-setting level.

unit in the room.
Please adjust the precedence-room setting to match your life
style. Moreover, for precedence-room settings, please consult
the service shop where you bought the unit.

NOTE
<Note for heat pump mu lti system>
When two or more indoor units have no precedence-room
settings and are set to modes that differ from each other, the
indoor unit which is operated first activates, while the other
indoor unit does not activate and the OPERATION lamp blinks.
(This is not a malfunction.)
An indoor unit that is not in operation will automatically start
and operate in the mode in which a previously operated indoor
unit was stopped. However, if the unit in operation provides
only COOL and DRY modes, simultaneous operation is
possible.

Notes on "Good sleep cooling operation"
l
We adopt the 1/f fluctuation rhythm in temperature control.
A 1/f fluctuation rhythm is used in temperature control. With it, temperature is fluctuated within a ±1˚C
range of the set temperature.
The 1/f fluctuation is comfortable rhythm existed in the natural world. (refer to "What's the 1/f
fluctuation")
l
Air blow is the lowest when the fan is set to "AUTO".

If you don't like this function, change the operation mode. (See page 8)
What is 1/f fluctuation...
It seems irregular but there seems to be a self-resemblance rule in our mother nature.
For example, the waves in the ocean forms irregularly but when you look at the coast line, there are
some places where they look similar.
When you look close around you, our heart doesn't beat in regular intervals but shows "1/f
fluctuation" in a long term. The research shows this "1/f fluctuation" and comfort has some kind of
relation and is applied to the comfort control fiels.
