Properties
- 4 outputs for controlling single or multi-stage compressors or fans
- Proportional output (PWM) for speed control via an inverter
- Input for pressure sensor (PGT 8 / 15 / 35), or temperature sensor NTC10k
- 2 digital inputs with potential-free contact (function can be parameterized)
- 3 optically isolated, digital voltage inputs for system diagnostics
- Choice of control algorithm between rotation of outputs / sequential activation / power optimization
- Changeover contact output for alarm management
- Storage of the last 9 alarms
- Automatic maintenance indicators
- Pressure – temperature – circuit depending on the refrigerant used
- RS485 interface for integration into monitoring systems
Advantages
- Suction and condensation control / pressure and temperature-controlled
- Option to control a speed-controlled compressor
