Caution:
• before carrying out any maintenance, disconnect the controller from the power supply by moving the main system switch
to “off”. Once having powered down the controller, wait at least 5 minutes before disconnecting the electrical cables;
• always make sure that the compressor has stopped completely. Freely rotating motors may generate dangerous voltages
across the terminals on Heosone, even when this is not powered;
• the controller does not feature protection against short-circuits to earth; suitable devices must be used to detect faults
upstream of the circuit.
