1-1 Temperature Adjustment
a. Normal control
Proportional control (P control)
When the temperature zone changes, this control
changes the frequency by one rank to move closer
to the set value.
When the temperature zone changes, this control
changes the frequency by one rank to move closer
to the set value.
Integral control (I control)
When the temperature zone has set time in the
same zone, this control changes the frequency
by one rank to move closer to the set value.
(Excluding the h zone.)
When the temperature zone has set time in the
same zone, this control changes the frequency
by one rank to move closer to the set value.
(Excluding the h zone.)
b. Initial control
The initial frequency is determined as shown in
the tables below based on the difference between
the temperature adjustment setting at the
beginning of operation and the room temperature.
After operation begins, normal control is performed
and therefore the correspondences in the tables
below will not hold.

c. Temperature adjustment
The temperature adjustment range is changed by
changing the operating mode with the operation switch.
changing the operating mode with the operation switch.
(1) Heating
If the room temperature is in the z zone when
operation begins, proportional/integral control is
not performed, and the machine runs at frequency
code c full power until the i zone is reached. When
the i zone is reached, the frequency changes to
the frequency code determined by fuzzy calculation,
and after that proportional/integral control is
performed.

(2) Cooling
If the room temperature is in the c zone when

(3) Indoor fan and operating frequency
The indoor fan has 12 speeds, and changing is done
in four stages, "Auto", "High", "Med", and "Low". The
relations between the indoor fan speed, air quantity
setting, operating frequency, and indoor heat
exchanger are shown in the following charts.
