regardless of the room temperature.
"Lo" mode operation is done
regardless of the room temperature.
Refer to page 45.
"Lo" mode and "Stop" mode are

compressor operation.
Refer to page 49.
Operation mode is changed to one
of "Super lo", "Lo", "Med", "Hi",
"Super Hi" and "Stop" according to
the room temperature, time and
heat exchanger temperature.
When the heat exchanger
temperature becomes 18˚C or less
except for the preheating
operation mode, "Stop" is set.
(The operation recovers at 18.66˚C)
Operation mode is changed to one
of "Lo", "Med", "Hi", "Super Hi" and

Refer to page 51 and 53.
The following operation mode is
set depending on the room
temperature when the operation is
started.
However, in the auto cooling
mode, the Cool rhythm

temperature becomes the
preset tempe 0.66˚C after
the Dash operation is
completed.
Note:
1. Refer to data in Page 41 Table 1 and 2 for each constant shown by capital letters in the diagram.
Note
(1)Mode is not changed after the
operation is started.
(2)The preset temperature can be
changed within
±
3˚C using the
room temp. control button " "
"V". For example, if the preset
temperature for cooling is
increased by +2˚C to change it
to 29˚C, the preset
temperature for heating is also
changed to 25˚C.
Also the operation mode
selected from the room
temperature at the start of
operation is judged based on
the changed value.
