In this Automatic run mode , based on the automatic setting temperature ,the set
temperature can only be changed 2 ℃(up & down)
Once the machine being shutdown , after 5 minutes stopping period ,the running
mode would be set again base on the room temperature .

4.2.1 Temperature compensation
Principle for compensation: The compensation is available only if the proper
sensor is used and it is not available when it is subject to the sensor on the
remote controller.
4.2.2 Outdoor Fan
The outdoor fan's speeds are divided into two levels which can be changed over
according to outdoor ambient temperatures.
When operating at a fixed frequency, the outdoor fan is forced to operate at the
high speed.
4.2.3 Indoor fan
When the fan speed is set at the high, medium and low fan speeds, the fan runs at a
preset speed. When the fan speed setting is automatic, the fan speed is set based on
the difference in room temperatures.

4.2.4 Prevention against condensation and insufficient heat exchange at the low
indoor fan speed.
When the indoor fan speed is set at the low fan speed, the compressor's power is
restricted as in the low temperature cooling.
4.2.5 4-way valve
State: It is interrupted in cooling.
Switchover: When initially powered on for cooling, the 4-way valve is interrupted
immediately.
When the heating is changed to the cooling, it needs an interval of 50 seconds for the
4-way valve to change over from being activated to being interrupted.
4.2.6 Cooling-pre mode
When start machine in cooling mode, the flaps will switch to cooling-pre angle,
