    AE-X4M30PU FUNCTIONS 1. FREQUENCY CONTROL 1) AC current peak control Cooling mode Heating mode 17.6A 18.4A 2) Prevention control of outdoor heat exchanger overheating If the temperature of the outdoor heat exchanger exceeds the overheating prevention line 1or 2 during cooling, the operating frequency is lowered by approximately 5 to 15Hz.
  • Page 14 AE-X4M30PU 5. SERIAL SIGNALS Serial signals consist of all 96-bit signals. If the condition as outdoor unit unable to receive a serial signal from the indoor unit continues for 30 seconds, it closes the expansion valve which corresponds to the room which can not be communicated. If all indoor units can not communicate with the outdoor unit, the compressor is stopped.
  • Page 15 AE-X4M30PU 3) During defrosting When defrosting begins, the compressor stops. Approximately 1 minutes later, the compressor reactivates in the refrigeration cycle, and the outdoor heat exchanger is defrosted. Each mode is as follows: The outdoor fan is s topped. The operating frequency is as shown in the table below.
