13. Operation Control
13.1 Basic Function
Inverter control, which equipped with a microcomputer in determining the most suitable operation mode as time
passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operation
mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and
performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by
the microcomputer at indoor unit that judging the condition according to internal setting temperature and intake air
temperature.
13.1.1 Internal Setting Temperature
Once the operation starts, remote control setting temperature will be taken as base value for temperature shifting
processes. These shifting processes are depending on the air conditioner settings and the operation environment.
The final shifted value will be used as internal setting temperature and it is updated continuously whenever the
electrical power is supplied to the unit.

13.1.4.2 Automatic Operation (For Single Split Connection Only)
y
This mode can be set using remote control and the operation is decided by remote control setting temperature,
remote control operation mode and indoor intake air temperature.
During operation mode judgment, indoor fan motor (with speed of Lo-) is running for 30 seconds to detect the
indoor intake air temperature.
Every 10 minutes, the indoor temperature is judged.
For the 1st judgment
o If indoor intake temperature - remote control setting temperature 3.6°F, COOL mode is decided.
o If -3.6°F indoor intake temperature - remote control setting temperature < 3.6°F, DRY mode is decided.
o If indoor intake temperature - remote control setting temperature < -3.6°F , HEAT mode is decided.

For the 2nd judgment onwards
o If indoor intake temperature - remote control setting temperature 5.4°F, if previous operate in DRY mode,
then continue in DRY mode. otherwise COOL mode is decided.
o If -3.6°F indoor intake temperature - remote control setting temperature < 5.4°F, maintain with previous
mode.
o If indoor intake temperature - remote control setting temperature < -3.6°F, HEAT mode is decided.

Feedback control
o Immediately after the fan motor started, feedback control is performed once every second.
o During fan motor on, if fan motor feedback 2550 rpm or < 50 rpm continue for 10 seconds, then fan motor
error counter increase, fan motor is then stop and restart. If the fan motor counter becomes 7 times, then
H19 - fan motor error is detected. Operation stops and cannot on back.
13.4 Outdoor Fan Motor Operation
Outdoor fan motor is operated with fan speed number of rotation. It starts when compressor starts operation and it
stops 30 seconds after compressor stops operation.
