  • Page 32: Regulation

    6. REGULATION The regulation is based on the temperature measured by the thermostat probe (P1) with a positive differential compared to the set point: if the temperature increases and reaches the set point plus differential, the compressor will start. The compressor will stop when the temperature reaches the set point value again.
