7.6 COMPRESSOR
The compressor regulator operates when at least one relay output is configured as the compressor uc1...uc6 = 4.
The switching on/off of the compressor is controlled by:
• TemperaturereadbyprobePb1;
• Congurationoftheheatregulations;
• Defrost and dripping.
Conditions for activation
The compressor is activated if the following conditions are met:
• Thecontrollerison(regulationisblockedwhenthecontrollerisinstand-by);
• ProbePb1isworking;
• Compressor activation delay C0 from switch-on is terminated;
• Compressor switch-on delay C2 between 2 consecutive activations;
• If d1=0,2,defrostanddrippingmustbeterminated.
