For example:WDF21A-K-EX
W-------thermostat.
1-------Model: P-common type, D-constant temperature and replacement type, Y- high temperature type.QS- Maual reset, M-the type of DAMPER THERMOSTAT
2-------When the temperature of cold (low) cut is over 0 ℃， no expression, otherwise it is expressed with “F”
3-------The absolute value of the temperature of cole (low) opened (OFF).
4-------Design series revised, indicated by Chinese spelling order A,B,C…
5-------K-K type of RANCO,A-A type of RANCO,D-the type of DANFOSS,L-the type of SAGNOMIYA.
6-------S-defrosting thermostat, X-signal thermostat, Ex-explosion-proof thermostat
Principle
The pressure of working medium in bellows, caplillary and sensor will varied with the temperature in the controlled object. The expression of bellows makes the bar to move via a lever and so the mini-switch works ON and OFF.
Far from vibration. Radius of capillary should be more than 20mm.The sensor must be impressed 150mm at least by varied temperature at the one trolled object.
The temperature in the controlled range could be made with turning the cam,i.e., the temperature goes down with clockwise and goes up with counter clockwise. All the screws on the thermostat have been sealed.
Pressing the defrost button when it needs defrost button when it needs defrosting, and then the refrigeration stops when defrosting. When the temperature rises to the lever, the thermostat resetting automatically and returning to work accordingly.
Turning the cam to a position for a force-off thermostat when the refrigerator equipment needs to be stopped temporarily. The power should be cut off if stopping working for a long time.
THE SWITCH
The arrow indicates the temperature rising; The sign C.L.H,3.4.6 are terminals; C.L. is the terminal of the SAGINOMYA type;3.4.6 is the terminal of RANCO type.
