5.2.6.2˖TC high temperature-preventing control of the indoor heating unit˖
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 ć
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. ć

5.2.6.3 The control of preventing the overcurrent of the compressor˖
●During the starting process of the compressor, if the curren of the compressor is greater than 12A for
3 seconds, stop the compressor and alarm, after 3 minutes, start it again, if such state appears 3
times in 20 minutes, stop the compressor and alarm, and confirm the malfunction. Then continue to
run it only after the the power is off.
●During the starting process of the compressor, if the AC current is greater than 11A, the frequency of
the compressor decreases at the speed of 1HZ/second.
●During the starting process of the compressor, if the AC current is greater than 10A, the frequency of
the compressor decreases at the speed of 0.1HZ/second.
●During the starting process of the compressor, if the AC current is greater than 9.5A, the frequency
of the compressor increases at the prohibited speed.
●During the starting process of the compressor, if the AC current is greater than 9A, the
