WK series temperature controller is a modern pressure responsed control device．
　　The product are widely used for the refrigerator，cold beverage machines， renrgerating storages，icecream machines etc．

　　When temperature of the sensing bulb goes up or down，bellows in temperature controller will be mpressed or lengthened， so push the switcher by lever arm in cut－on or cut－off status．So that it can protect sys tern working in normal status．
　　 The temperature of temperature controller’s proper is indicated by symbols TS．the temperature of sensor bulb by Tb.
　　 The direction of switch action during temperature increasing is indicated by the arrow－head．
　　 The length of capillary tube may be meter，3 meter or special specification to 10 meter．

　　 1．The sensing bulb of the temperature control should be set in the tem perature controlled area with good air ventilation and correct temperature indicated．
　　 But it should be taken care to place the sensing bnlb on the return air side instead of cold air outlet side，where air cooler is used in the cold storage.
　　 2．The capillary tube between the sensing bulb and the boby of control should not Pass through the region with temperature olwer than the temperature controlled, nor should it be in contact with other pipes.
　　 3．During installation，the radius of bend lug curvature for the capillary tube should not be less than 60mm., and the capillary tube shuld be clamped with straps 3OOmm.apart
　　 4．By turning the button of main adjusting screw and differential adjusting screw （before turning the locating washer should be turned off），the temperature and differential temPeature settings may be adjusted respectively according to he values indicated on he scale．
　　 5．Mounting size：62X43.5mm．
