Adjusting the temperature “ON-OFF” or “proportional” (0-10V). By adopting the regulation “proportional”, they avoid thermal shock conditions when the outside temperature is very low.

This system can also be identified as an emergency system to cool the room as it is provided an electromechanical controller (thermostat) that allows to feed the fan in an independently and separately when the detected temperature exceeds the predetermined values and simultaneously indicates the condition of emergency operation.
