     PWM configurable: 2.5 ,4, 6, 8, 10 kHz * auxiliary cooling fan of the VASCO, used in wall mounted applications, has a protection rating of IP20. If you require the version with IP55, please contact the supplier. VASCO is able to power the motor with a higher current for a short period of time according to the linear relation: 101% of the nominal current for 10min., 110% nominal current for 1 min.

    5.1.2 Pressure sensor VASCO requires a pressure sensor with a linear output signal within the range 4 – 20 mA. The pressure transducer can be powered by any range of DC Voltage which includes the value 15 V dc. It is necessary to set the pressure sensor characteristics in the initial configuration menu or in the installer menu (please check the relevant chapter on setting parameters).
