SmartFan® Cirrus-2 is a programmable fan controller designed to monitor and manage one or two 12, 24 or 48VDC PWM 4 wire fans or blowers. The Cirrus-2 fan controller is easily programmed using the Navigator PRG00-F handheld remote programmer, removing the expense of a display and keypad from each fan control unit. Using the Navigator, one can customize the fan control curve, alarm thresholds, fan ON/OFF thresholds, control signal inputs, fan frequency, optional transducer supply voltage, fail-safe modes and more. Factory programming and customization available for orders as low as 50 pieces.
