When the heating command is sent out, it is started to calculate the system load demand value. If the load is 0,
all the loads will not be put into operation. If the load is >0, the EXV will be firstly opened to step Y; then the outdoor
fan is started. After 30 seconds, the compressor will increase its frequency to the required initial frequency 40Hz
before it started. It is started to count the time when the compressor frequency is increased to 20Hz. After 10
seconds, the 4-way valve is energized and then the indoor fan will run as per cold air prevention mode. The
compressor will keep running at initial frequency for 3 minutes. After that, the compressor, EXV and outdoor fan will
adjust according to logic.
