ELECTRICAL ACCESSORIES Intelligent elements for demand controlled ventilation VRPZ Electronic control with display for single phase 230V-50/60Hz fans. Analogical input 0-10V or 4-20mA: The fan works proportionally to the input value with adjustments of the minimum and maximum values of the inputs and outputs. “ON/OFF”: when the potential free contact (f.e. clock) close, the fan putting into operation according to the voltage of the analogical input. This connection associated to a PIR detector allows to have a ventilation system type minimum-maximum. Input « maximum speed »: given an external signal, the fan works at a maximum adjusted speed. Outputs: Magneto-termic dry contact. Illumination 230V 50Hz (max. 8A). Electrical supply master/slave 24Vdc (max. 100mA).
