Fan speed controller Introduction The fan speed controller (FSC) YMC706 is designed to control the speed of fan motor used in the outdoor air-cooled condensing unit, also can be used for other type of the motor to control the running speed(heatpump system and water-cooling condenser pump etc. The fan speed controller collects the signal of the condensing temperature of the system and automatically adjusts the motor speed according to the set program so as to reduce the power consumption and stabilize the system pressure, especially during the winter when the ambient temperature is extremely low, it can raise the condensing temperature (pressure) to maintain refrigeration system in good performance. For example, when use air-cooling condenser the condensing temperature (pressure) is high, the fan speed controller will speed up the fan motor to reduce the condensing temperature (pressure); when the condensing temperature (pressure) is low, the fan speed controller will be able to adjust a low running speed to maintain a condensing temperature (pressure) Features and Benefits ·Condenser pressure(temperature)control by fan speed variation ·Temperature input ·Panel control ·Stepless ·Save power ·Low noise ·increase the life of compressor and fan motor
