  • Page 12: Operation Under Thermoregulator Call (Default)

    i-MAX Industrial inverter air/water heat pump with axial fans 7.2.1 OPERATION UNDER THERMOREGULATOR CALL (Default) During this operating mode (P03=1), the thermo-regulator actuates the circulator; after a time delay of P01 seconds from the circulator pump startup, the compressor also will turn ON. However, during the power off status, the circulator pump turns off with a delay of P02 minutes after shutdown status by mean of the thermo-regulator (the shutdown status is corresponding to the off status of the compressor).

    i-MAX Industrial inverter air/water heat pump with axial fans Example in cooling operation: If the difference in temperature between water inlet and outlet is greater than P09 + P10, the pump will run at maximum speed. If the difference temperature between water inlet and outlet is less than P09 - 0.2°C, the pump will run the minimum speed. In the other cases, the pump modulates trying to match the temperature difference with P09.
