• receive a setpoint speed selection or setpoint control-value selection and transmit the same to the fluid delivery device (4);
• and
• a control module (14) communicatively connected to the central control unit (10) to receive the commands and actuate and/or regulate the fluid delivery device (4), wherein the control module is configured to:
• supply a first-time operating power to the fluid delivery device (4) when an emergency mode is deactivated,
• establish a communications connection (12) between the control module (14) and the central control unit (10), and
• activate the emergency mode of the fluid delivery device (4) when the setpoint speed selection or the setpoint control-value selection exceeds a trigger value or the fluid delivery device (4) is operated at an invalid speed or with an invalid control value for longer than an activation time, wherein the emergency mode operation comprises maintaining a cooling function for the fluid delivery device.
