Once the machine is started, it can run TTC overheating protection of air-blowing, but air-blowing
sensor malfunction must alarm after 4 minutes during which the compressor is started (during the
course of self-detection, there’s no such limitation)
Sensor detection methods: 100 times (one cycle of procedure run is one time, and about 5ms,
detection method for each time: continuously sampling for 8 times, then order them and take the
mean value of the middle 2 values), take the mean value.

the indoor, others don’t last.
Tpg_indoor is the highest value of the effective indoor unit (start it and it is in accord with the
running state).
The indoor heat exchanger sensor tests the temperature of the indoor heat exchanger. If the
temperature is higher than 55 , decrease the rotate speed of the compressor and do the high
temperature-preventing protection of the indoor heat exchanger; if the temperature of the indoor
heat exchanger is lower than 47 , recover to the normal control.
