2) Heating mode:
when the unit detects that the indoor main display panel is started to heat, the four-way valve is switched to the air coil pipeline;
when a user selects a floor mode, the four-way valve is switched to a floor heating pipeline, and meanwhile, the two-way valve on the water collector is opened;
