20. VARIOUS PROTECTIONS
1. DISCHARGE GAS TEMPERATURE OVERRISE PREVENSION CONTROL
The discharge gas thermosensor (discharge thermistor : Outdoor side) will detect discharge gas temperature.
When the discharge temperature becomes higher than Temperature , the compressor frequency
is decreased 20rps, and it continues to decrease the frequency for 20rps every 120 seconds until
the temperature becomes lower than Temperature .
When the discharge temperature becomes lower than Temperature , the protection control of the
compressor frequency will be released.
When the discharge temperature becomes higher than Temperature , the compressor is stopped
and the indoor unit body Operation lamp and Timer lamp starts blinking.

2. CURRENT RELEASE CONTROL
The compressor frequency is controlled so that the outdoor unit input current does not exceed
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.
