5-10 Protection operations on outdoor unit
5-10.1 Overheating
During cooling operation as soon as the outdoor coil temperature (OCT) increases, compressor speed
is reduced in order to avoid heat exchanger overheating. System stops compressor operation when OCT reaches 60 °C
5-10.2 Compressor discharge temperature
During operation, as soon as the discharge temperature increases, (CDT) compressor speed is reduced
in order to avoid overheating of the motor. Compressor is stopped when CDT reaches 105°C
5-10.3 Compressor power-module overheating
The module temperature, detected by a built-in thermistor, is always monitored by the control system and kept
operating in a safe area. If temperature exceeds 100°C, operation is automatically stopped.
5-10.4 Outdoor fan power-module overheating
The module temperature, detected by a built-in thermistor, is always monitored by the control system and kept
operating in a safe area. If temperature exceeds 100°C, operation is automatically stopped.
5-10.5 Compressor power-module overcurrent
In case of current driven to each motor phase greater than 10 A operation is automatically stopped
5-10.6 Outdoor fan power-module overcurrent
In case of current driven to each motor phase greater than 400mA operation is automatically stopped
