Characteristics:
Power: 3phase 4 wire
Rated Voltage: AC 380/220V  ±10%
Working Condition：temperature at 0-60℃， relative humidity （RH）≤85%, non-corrosive air.
Temperature control:  0-50℃
Feature: simple operation，Manual-Off-Auto control free change.  Control two groups of fans turn on or off as per temperature variation.  Effectively avoid current fluctuation when fans start on in same time, meanwhile avoid temperature dropping.
Usually be used in the wall to control the fan and cooling pad,when the inner temperature is higher than the demanded temperature,will run or stop one group fans and cooling pads according to the temperature.If the temperature is much higher ,will control another group fans and cooling pads to run or stop.
