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 ≥ 2°C, COOL mode is decided.
o If -2°C ≤ indoor intake temperature - remote control setting temperature < 2°C, DRY mode is decided.
o If indoor intake temperature - remote control setting temperature < -2°C, HEAT mode is decided.
