18. 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 higher than 105°C ,the compressor frequency
is decreased 20 Hz, and it continues to decrease the frequency for 20 Hz every 120 seconds until
the temperature becomes lower than 105°C .
When the discharge temperature becomes lower than 95°C ,the control of the compressor
frequency is released.
When the discharge temperature becomes higher than 110°C ,the compressor stops.
When the discharge temperature becomes lower than 80°C ,the compressor operates.
2. CURRENT RELEASE CONTROL
01-17
The compressor frequency is controlled so that the outdoor unit input current does not exceeds
the current limit value that was set up with the outdoor temperature.
The compressor frequency returns to the designated frequency of the indoor unit at the time
when the frequency becomes lower than the release value.
3. ANTI-FREEZING CONTROL (Cooling mode)
The compressor frequency decreases on cooling mode when the indoor heat exchanger
temperature sensor detects the temperature lower than 3°C or 2-way valve temperature
sensor detects the temperature lower than 2°C.
