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
When the outdoor unit heat exchanger temperature reaches trigger condition below, the compressor
is stopped and trouble display is performed.
Trigger condition
149.0°F (65°C)
8-5. 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
226.4°F (108°C)
Release condition
176.0°F (80°C)
(3 minutes after compressor stop)
