Economy Operation; 10C Heat Operation; Various Protections; Discharge Gas Temperature Over Rise Prevention Control - Fujitsu AU*G36LRLA Service Instruction

1-20. ECONOMY OPERATION

The ECONOMY operation functions by pressing ECONOMY button on the remote controller.
At the maximum output, ECONOMY Operation is approximately 70% of normal air conditioner operation
for cooling and heating.

1 -22. VARIOUS PROTECTIONS

1. DISCHARGE GAS TEMPERATURE OVER RISE PREVENTION CONTROL

The discharge gas thermosensor (discharge thermistor : Outdoor side) will detect discharge gas temperature.
When the discharge temperature becomes more than 105°C, the compressor frequency -10rps,
and it continues the frequency -10rps every 2 minutes until the temperature becomes less than 105°C.
When the discharge temperature becomes less than 100°C,
the control of the compressor frequency is released.
When the discharge temperature becomes more than 115°C,
the compressor is stopped.
2. COMPRESSOR TEMPERATURE PROTECTION CONTROL
When the compressor temperature thermistor detects more than 110°C, the compressor is stopped at once.
