6-3-8 Heating-run mode
6-3-8-1 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 or line controller.
6-3-8-2 Indoor fan
The fan speed is set at the high, medium or low fan speed, it operates at
a preset speed (in the cold air prevention, it is forced to run at the
ultra-low flowrate or stop).
When the fan speed is set in the auto-run, the fan speed setting is made
according to the room temperature differences (except for the cold air
prevention).

6-3-8-3 Cold air prevention
In the heating-run, to prevent the indoor fan from blowing cold air, the
indoor fan speed is different from the set speed after turning on
air-conditioner.
6-3-8-4 Residual heat blowing off
When the compressor is turned off in the heating run, the indoor fan does
not stop at once, but until the indoor evaporator temperature is below
23
0
C, but for 30 seconds at the latest.
6-3-8-5 Outdoor fan
The outdoor fan speeds are divided into three levels which can be
changed over according to outdoor ambient temperatures.
6-3-8-6 4-way valve
State: It is electrified in heating.
Switchover: When initially powered on for heating, the 4-way valve is
activated immediately.
In the change from cooling to heating, it needs an interval of 50 seconds
for the 4-way valve to change over from being interrupted to being
activated.
