DETAILS
Precisely modulate the speed of ventilation fans in response to changes in ambient temperature. Optimum air circulation is maintained in ventilated areas and buildings with minimum noise and efficient use of energy. A thermistor monitors the air temperature and, as the temperature rises or falls within a preset band above set point, the fan speed is correspondingly increased or reduced between maximum and minimum idle speed values. The idle adjustment control setting includes a "zero-power FAN STOP" position at which fan speed is stopped when ambient temperature is below setpoint. This "zero-power FAN STOP" function will be over ridden by temperature control functionality meaning that power will be applied to the fan when the ambient temperature exceeds setpoint. Modulating band above set point, between the maximum and minimum speeds, is fixed at 6 deg. Temperature set point is adjustable from 35 to 95 deg F. Especially designed for agricultural buildings, although of broad application in all ventilated areas, these fan controls are compact units designed to fit on a standard 4x4 junction box. Construction protects the electronic controls against dust and solid state design ensures long life and reliable operation. Fan speed motors must be permanent split capacitance or shaded pole with built-in thermal fuse. Load must decrease as RPM increases and bearings should be capable of operating at minimum RPM for phase angle speed control.
