8-3. Current release control
The rotation number of compressor is controlled so that the outdoor unit input current does not ex-
ceeds current limit value set according to the outdoor temperature.
The rotation number of compressor returns according to the operation mode, when the current be-
comes lower than the release value.

8-4. Compressor temperature protection
When the compressor temperature sensor detects higher than the trigger condition below, the com-
pressor is stopped. When the compressor temperature sensor detects the release condition, the pro-
tection is released.
Trigger condition 108°C
Release condition
80°C
(3 minutes after compressor stop)
8-5. High pressure protection
Trigger condition
Pressure switch: Off (Open: Higher than 4.2 MPa)
Compressor stop
Release condition
Pressure switch: On (Close: Lower than 3.2 MPa)
(3 minutes after compressor stop)
Compressor restart
8-6. Low outdoor temperature protection
When the outdoor temperature sensor detects lower than the trigger condition below, the compres-
sor is stopped.
