					                    WS-01A temperature and humidity control instrument
Ⅰ、Main Technical Indexs
  1、 size:80×160           hole:76×156
  2、 measure precision:humidity display less than 3%, the humidity control less than 3%
  3、Temperature display less than 1%, the temperature control less than 1%
  4、Relay output contact capacity:AC220V/ 7A
  5、 Range of the temperature :  CU50(-19.9~150℃) Range of the humidity:       0~100%RH
  6、Power voltage:AC85~242V ~50Hz
  7、Work environment:temperature 0~50.0℃, relative humidity≤85%RH, without corrode
  and strong electric radiation.
Ⅱ、Instrument panel and connection scheme




Ⅲ、meter operater
   1、You need install the humidity sensor at need test humidity’s occasion.
   2、Make the meter be electrified after it connect the power、sensor and the control loop ,and
then it check itself:All the shine tube strokes lighten (except OUT light)  ,so as to test whether
the luminescent system is normal。If some pieces couldn’lighten,stop using it and send to mend
(the process only last for 0.5S) ,and then enter into the normal test control state.
   3、Meter under the normal working condition:the left-above row nixie tube display the testing
temperature value ,and the below row display the temperature setting value.When the testing
temperature value is lower than the setting value,the temperature control output light will be
lightened,and output the temperature control.The right-above row nixie tube display the testing
humidity value,and the below row display the humidity setting value,when the testing humidity
value is lower than the setting value,the humidity control output light will be lightened,and
output the humidity control.

                                              1
                           temperature       Use this to plus or minus If there is
           SC1             error modify      error during testing temperature.                   -19.9~20
           Hy2           Humidity return                      The same as abve                   0.1~50.0
                         difference
                                             Meter ’ s on-off control insensitive                0.1~50.0
           Hy1              Temperature      interval.if the value↓the control effect
                         return difference   will       get   well , the        relay   output
                                             continually         throb   will     affect   its
                                             operating life.
                            Humidity         Use this to plus or minus If there is
           SC2             Error modify        error during testing humidity.                    -19.9~20
     1、Setting temperature value:press left▲key or▼key 3s,then enter into the temperature
  setting state,press▲key or▼key to change the value.Long time to press ▲key or ▼key to
  plus and minus,   after modify the parameter value,    press any key on the right to save and exit or
  wait for 5S to save and exit automatically.
     2、Setting humidity value:    press right▲key or ▼key 3 second,then enter into the humidity
  setting state,press▲key or▼key to change the value.Long time to press ▲key or ▼key to
  plus and minus,   after modify the parameter value,    press any key on the right to save and exit or
  wait for 5S to save and exit automatically.
     3、                                                (        :
        Setting the modify value of temperature error SC1) simultaneity press left▲key and left
  ▼key 3S to enter into the temperature error modify SC1 setting state,left-above row nixie tube
  display the parameter ‘SC1’     ,and the left –below row display SC1 parameter value,press▲
  key or ▼key to modify the parameter,Long time to press ▲key or ▼key to plus and minus,
  after modify the parameter value,press any key on the right to save and exit ‘SC1’setting
  state.then enter into the temperature return differences value ‘Hy1’setting ,left-above row
                                             ,
  nixie tube display the parameter ‘Hy1’ the left-below row display Hy1 parameter value,           ress
  ▲key or▼key to change the value.Long time to press ▲key or ▼key to plus and minus,              after
  modify the parameter value,press any key on the right to save and exit or wait for 5S to save
  and exit automatically.
     4、 same method
        The               (press any key on the left) humidity return difference Hy2、
                                                        set                                  humidity
  error moditySC2,    after modify the parameter value,   press any key on the left to save and exit or
  wait for 5S to save and exit automatically.
     Wrong direction:
     5、meter control:
heating control:when the temperature measure value<setting value-Hy,the meter start
             hearting,the light of heat is lighten.
humidity control:when the humidity measure value<setting value-Hy 时,the meter start
             humidify control,the light of humidity lighten.
  Pv window display  “HH”                           the                              or
                              means sensor break、 testing value is overloaded, the type of the
  sensors are not matched with.;when display “LL”means the testing value excess lower-limit
  or the sensor should be connected wrong.
