The INT102 F electronic control unit is used for demand-oriented control of multi compressor packs with up to three refrigeration compressors. In this case, the first compressor is controlled in a continuously variable manner using a frequency converter.
The INT102 F electronic control unit for multi-compressor packs determines the suction pressure with a pressure transducer, using the difference between the set value and actual value to calculate the optimum frequency for the frequency converter and the switch-on and switch-off times for the compressor stages. The set value is adjusted with the display and the two-button control. The start-up parameters are stored at a separate level and can be protected with a password. Additional pressure transmitter can be connected to limit the high pressure.
