2.2.1 Based Control
2.2.1.1 Compressor Control
When cooling or heating mode is turned on, indoor fan will run for a while before the compressor
starts. Under different modes, the compressor can only be stopped after running for some time (special
cases excluded). This is to protect the compressor from frequent start or stop. Once the compressor is
stopped, it must not be restarted right away. Please wait for a few minutes.
