  • Page 34: Evaporator Configuration

    HOT mode (mOd parameter=1) The NECTOR controller activates the hot resistance control when the ambient temperature drops below the set value minus the differential (r0); it switches off the resistance when the ambient temperature is higher than the set value.

  • Page 35: Changing Of Date And Time Settings

    NECTOR For the correct management of the system: - Connect the cycle reversal solenoid valve to the defrost output. - Connect the liquid solenoid valve to the liquid solenoid valve outlet (AUx = +/- 8) Doing so during the defrosting phase will ensure closing of the liquid solenoid valve and activation of the hot gas defrosting cycle.

    5.33 Parameters: Au1/2 (3°), StU (2°), r1 (2°). The NECTOR controller activates the humidity call when the ambient humidity drops below the set value StU minus the differential r1; it disengages the humidity call when the ambient humidity exceeds the set value. Configure Au1/2 = +/- 7 to enable a digital output as humidification consent.
