Technical data

9.4 Overheat outdoor exchanger

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 65 °C

9.5 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 111°C

9.6 Compressor power-module overheating

The module temperature, detected by a built-in thermistor, is always monitored by the control system an

kept operating in a safe area. If temperature exceeds 100°C, operation is automatically stopped.

9.7 Compressor power-module overcurrent

Operation is automatically stopped in case of current driven to each motor phase greater than 9
