Once the indoor unit started under heating operation, if the fan stops in any case (including starting up,
defrosting, fault, no capability needs), the anti cold air operation will keep before starting the fan for the next time.
Once the indoor fan is started, unless the fan stops, the anti cold air operation will not take effect even t

◆ Blowing Residual Heat Operation
When the indoor unit runs under heating mode, if it should be stopped for reaching the temperature spot, fault,
defrosting etc., you should carry on the blowing residual heat operation before stop, in order to exclude the inner
surplus heat of evaporator and electric heater.
When the indoor unit needs to carry out blowing residual heat operation, the indoor fan should be switch to low
fan speed, and turn off the indoor fan after running the corresponding period T

Special case: For the indoor units of cassette series, it will run at low fan speed when it reaches the temperature
point, and do not need to stop the fan.
3) Compensation for Heating Temperature
Under the standard conditions, when the air conditioner is running, the units will regulate the capacity output of
indoor unit according to its setting temperature and air inlet temperature, and in order regulate the indoor
temperature to the set temperature. When the air conditioner is installed too high and under the heating mode, the
hot air will easily gather up due to the density, so the temperature of living space may not reach the set
temperature, leading to uncomfortable feeling.
Therefore, you should use the temperature compensation function under heating mode: to reflect the real
temperature of living space by reducing 2 degrees of the air inlet temperature. You may keep comfortable
temperature in the living space. Shown as the following figure:
