According to temperature and humidity sensor’s signal of ventilation heating,cooling and others,microcomputer controllerset the parameters in a certain curve to meet requirement of livestock growth,and the characteristics are as follows:

 1.All Closed waterproof chassis,IP65,easy installation secure and reliable,large screen LCD,Chinese demonstration,man-machine interface,convenient parameters set,

 2.8 stages,constant blowing,cooling equipment,heater,

 3.Access up to two temperature sensors and humidity sensor,in shorter time it gets accurate average temperature,

 4.Through the set of six fixed temperature curve and the smallest ventilation,the controller can adjust the temperature timely according to requirement,

 5.Setting minimum ventilation and circulation,

 6.Unique horizontal and vertical ventilation switch,

 7.Temperature setting for comfortable environment,

 8.Simulation operation:build-in minimum ventilation,avoiding catastrophic accident in case of controller failure,

 9.Special protection when starting,

 10.Controller can be connected to the computer,which brings easy information collection and different control strategy.
