AH/AY-X13CR
FUNCTIONS
AH-X08CR/X10CR/X13CRare not provided with the
heating function.
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.

(Hot keep fan)
Although the initial value
of the h zone is 1, it changes
to 2 after a lapse of 15 minutes.
Full power
operation only
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 caiculation,
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.
Differential

AH/AY-X08CR
AH/AY-X10CR
AH/AY-X13CR
(1) Control for indoor freezing prevention
If the temperature of the indoor heat exchanger stays
below approximately 0°C for four minutes during
cooling or dry, this control stops the compressor. Over
2°C the compressor will run again.
(2) Control for cold air blowing prevention
When heating begins, this control stops the indoor fan
until the temperature of the indoor heat exchanger
reaches 26°C. It also stops the fan if the temperature
goes below 23°C during operation.
(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.

1-3 Hot keep
If the room temperature is in the j or k zone during
heating, the compressor is turned on and off to
prevent overheating.
The fan goes off 30 seconds after the compressor
goes off.

After "3 min. on - 3 min.off" is
repeated 4 times, the compressor
goes off, and only the fan
continues to repeat “3 min. on - 8
min.off’.
3 min. on - 8 min. off
1-4 Automatic operation
The operating mode and temperature setting are
determined by the room temperature and the external
air temperature.
The operating mode will changeover automatically
with the following condition.

1. From cooling to heating
Cooling mode will changeover to heating mode when
condition of indoor temperature 1.7°C lower than the
set temperature conditions for 5 minutes.
2. From heating to cooling
Heating mode will change over to cooling mode when
condition of indoor temperature 1.3°C higher than the
set temperature conditions for 25 minutes under Hot
keep condition.
3. When the set temperature is adjusted within the
range of +2°C by the remote control's key. ('W 4);
the changeover judgement room temp. will also be
shifted within the range of +2°C.
1-5 ON-timer
The ON-timer is set by pressing the ON-timer burton.
In order to attain the set temperature at the set i me,
the operation starting time is corrected by fuzzy
computing one hour before the set time.
