compressor, indoor fan run 5 minutes in low speed. And repeat on and off cycle.

8.8.3 Low room temperature protection:

When room temperature decreases to below 10℃, the compressor and the outdoor fan
will stop(indoor fan is Breeze). Dehumidifying operation will be resumed when room
temperature restores to over 13℃.
8.8.4 Under dehumidifying mode, the anti-freezing function of the indoor heat exchanger is the
same as that of cooling mode.
8.9 Heating mode
8.9.1 Generally, the 4-way valve is open in heating mode, but it is closed in defrosting mode.
4-way valve must delay 2 minutes compared with compressor if the compressor changed
into non-heating mode or turned off. 4-way valve doesn't delay in dehumidifying mode.
8.9.2 Generally, the outdoor fan is turned off with the on-off action of compressor in heating
mode, except for the defrosting mode or the end of defrost.
8.9.3 Action conditions of compressor under heating mode: compressor must run for 7
minutes after starting and then judge temperature. Meanwhile other protections are still
valid.
