 CD-3700 digital intelligent digital temperature controllers and
         humidity controllers operating instructions
  
1、Product scope
CD - 3700 digital intelligent digital temperature controllers and humidity controllers are designed for all kinds of high and low voltage switchgear, box-type substation in the power system, internal environment of cabinet put oneself in another's equipment such as temperature, moisture and condensation prevention protection and design of measurement and control instrument. Especially suitable for high temperature and humidity control requirements of power distribution cabinets, terminal box, operating mechanism, relay protection and preinstalled type substation equipment.

  e.Working power supply: AC220V plus or minus 10%, power consumption < 5 w
  f.Installation method: card rail style installation, appearance size 48 * 48 * 80 mm
  g.Dry contact output relay capacity: AC220V / 3 a
  h.Sensors, temperature/humidity sensor module integrated terminal connection type
3、Product standards

  b.Electrical transient bursts immunity: GB/T17626.4
  c.Surge immunity: GB/T17626.5 requirements
  d.Electrostatic put reactance immunity: GB/T17626.2 requirements
4、The shape and the wiring diagram
5、Product features and using method
 a.Will gauge socket is installed on the card rail, in accordance with this manual step 4 connect the wiring diagram of the sensor, fan, heater and instrument communication power supply, plug in the socket and switch on the instrument when confirmed communication power supply, in order to guarantee the safety of the instrument, first of all, please disconnect the ac power socket, then instrument plug and wiring etc).
 
b.Self-checking instrument after turning on the power supply first, check whether the LED display and LED luminous tube work normally, press "set" button to enter during this period the hardware test mode, the "Ⅰ" and "Ⅱ" light at the same time, each time you press the "set" button, you can manually turn control ventilation and heat output, two minutes automatically quit the hardware test mode, enter the temperature/humidity measurement and control work.
Note: at any time, at the same time, press the "delta" and "del" key for 1 second, the instrument will implement a power function. Self-checking again!
 
c.The normal work of the instrument, every 3 seconds display cabinet put oneself in another's position inside temperature and humidity data in turn. When the light is "Ⅰ" light, said display value of temperature; When the light is "Ⅱ" light, said display value of humidity; The work of ventilation "ventilation" indicator light; The work of heating "heating" indicator light; Temperature or humidity sensor failure occurs, the appropriate temperature and humidity data is shown as "-- -". When there is a failure in the normal temperature sensor and humidity sensor, no longer shows that in turn and show only the temperature.
 
d.When humidity sensor failure occurs, cancel the humidity control functions; When the temperature sensor failure occurs, cancel all of the temperature and humidity control function.
 
e.Start heating conditions:
1) temperature measurement temperature or less start heating value or
2) humidity measured values or start the heating value
Stop heating conditions:
1) the temperature measured values or start the heating value + return difference and temperature control
2) humidity measurements humidity start heating value or less - humidity control back to the poor
Note: only when the temperature of 48 ℃ or less are allowed to start the heating; Unconditionally stop heating when the temperature is 50 ℃ or higher. In addition the temperature
And humidity respectively according to their respective actual measured value judgment independently start/stop heating.
 
f.Ventilation start conditions: (when the heater work, forced ventilation)
Temperature measured values or start ventilation set value
Ventilation conditions precedent:
Temperature measurement temperature or less start ventilation Settings - temperature control back to the poor
 
g.Control parameter setting:
 In normal control instrument and control operation state, long press "set" button for 3 seconds to loosen, the instrument will enter a state of control parameter Settings (in the state of setting all four LED indicator light will light up). Enter the set state, the display area will be the first to show the code to set the parameters selection menu, press "delta" or "del" button to choose code menu C1 to C7 (defined in the following table), under a certain code menu, press "set" key to enter to the shorter code parameter values of the menu Settings, according to the "delta" or "del" button can adjust the size of the parameter values, then click the "set" button, then back to the parameter Settings of code selection menu, you can press "delta" or "del" key again to continue to choose other control parameters setting, so can each take turns to set all the control parameters of instrument, set the parameters will be temporarily stored (will not take effect immediately), only when the long press "set" key again for three seconds to loosen, exit the Settings, set the values of the parameters will save and effective, no reset parameters will continue to maintain the original value; Continuous 90 seconds in the set state if no button operation, the instrument will automatically exit set state, will not save the new parameter value set, the original value.
                  
 
 
 
              
               Code parameter Settings menu table:

Code menu	Corresponding parameters content	The minimum value	The maximum	The default value	instructions
C1	Set the start ventilation and  temperature	30	70	40	℃
C2	Set the start heating temperature	-5	18	10	℃
C3	Set the start heating humidity	40%	90%	75%	RH%
C4	The temperature control back to the poor	4	10	5	℃
C5	Humidity control back to the poor	5%	20%	8%	RH%
C6	The machine address (unused)	1	255	1	本机地址
C7	Control mode selection (unused)	1	5	3

 
Note: sensors in connection in order to ensure the stable, first of all need to use the wire stripping tool at the end of wires are stripped the husk of the 7 ~ 8 mm, then exposing bare copper wire from the roots to bent 180 degrees, and together with the skin into the terminal to lightly tighten the screws on the terminal is ok (don't overexert when screw, in order to avoid cracking on!) .
