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.
(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.
FUNCTIONS
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 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
operation begins,proportional/integral control is not
performed, and the machine runs at frequency
code 9 power until the i zone is reached. When the
h zone is reached, the frequency changes to the
frequency code determined by fuzzy calculation,
and after that 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.
1-2 Indoor fan control
This control uses the thermistor for the indoor heat
exchanger to control cold air blowing prevention, the
indoor fan, and overheating prevention.
