  If your Swegon Chiller unit doesn't start and the display is off, there could be several reasons: * **No mains voltage**: Check that the main disconnect switch is in the “ON” position and verify voltage in the power supply line. * **No voltage to the auxiliary circuit**: Ensure that the protective devices upline and downline of the transformer of the auxiliary circuit are undamaged. If a protective device has triggered, reset it after addressing the cause.

  If your Swegon Chiller unit doesn't start but the display is on, it might be due to a lack of 230V auxiliary power supply. Check that the secondary circuit of the 230V transformer is intact, ensure that the protective devices downline of the 230V transformer are intact, and verify that the phase sequence is correct and the phase sequence relay is working.
