1. INDOOR UNIT
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.
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.

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.
(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 h zone is reached.
When the h zone is reached, the frequency
changes to the frequency code determined by
fuzzy calculation, and
integral control is performed.
(2) Cooling
If the room temperature is in the c zone when
operation begins,proportional/integral control is
not performed,
frequency code 9 power until the h zone is
reached. When the h zone is reached, the
frequency changes to the frequency code
determined by fuzzy calculation, and after
thatproportional/integral control is performed.
(3) Dry
After operation begins, 2 minutes (running at the h
zone) of the room temperature is stored in
memory, and that becomes the set value.
(4) Circulation
The frequency code 0 is sent to the outdoor
machine, and only the fan of the indoor machine
runs, the compressor does not run.
