22. VARIOUS PROTECTIONS

1. DISCHARGE GAS TEMPERATURE OVERRISE PREVENSION CONTROL

The discharge gas thermosensor (discharge thermistor : Outdoor side) will detect discharge gas

temperature.

ASU9 / 12RL

219°F(104°C)

214°F(101°C)

230°F(110°C)

When the discharge temperature becomes higher than Temperature ,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 Temperature .

When the discharge temperature becomes lower than Temperature ,the control of the control of the

compressor frequency is released.

When the discharge temperature becomes higher than Temperature ,the compressor is stopped

and the indoor unit LED starts blinking.

(Table 17 : Discharge Temperature Over Rise Prevension Control / Release Temperature)

Temperature

2. CURRENT RELEASE CONTROL

The compressor frequency is controlled so that the outdoor unit input current does not exceeds

the current limit velue 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.
