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. Cooling pressure over-rise protection
→hen the outdoor unit heat exchanger temperature reaches trigger condition below, the compressor
is stopped and trouble display is performed.
Trigger condition 65°C
8-5. Compressor temperature protection
→hen the compressor temperature sensor detects higher than the trigger condition below, the com-
pressor is stopped. →hen 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)
